CANADIAN FORCES DEPLOYED CAMP DESIGN

Captain G. Brent Thornhill, B.Sc. (Civ. Eng.) CD

Major Patrick J. Heffernan, Ph.D. (Eng.) P.Eng., CD

Canadian Forces personnel have been building temporary deployed camps for many years around the world to support operations in Canada's Arctic, for United Nations assistance and humanitarian organizations over the past 40 years. Increased construction and maintenance costs coupled with surge engineering effort to restore damage to permanent infrastructure from war or natural disasters has shifted the focus to the reusable, redeployable camps to house and support military personnel. Continued operations throughout the world encourage an environment where lessons learned are reviewed and revised. Military Engineers constantly strive to provide cost-effective, timely solutions to many of the challenges in providing a high standard of living while on deployed operations.

Short construction times, low life cycle costs, minimized maintenance efforts, low-skill set personnel define the focus of deployed camp planning and implementation. Expedient construction is required to support military operations in support of operations other than war, where commanders expect and demand full facility use in a very compressed time period. Cost comparisons to repairing permanent infrastructure have demonstrated that in time periods of less than normal use/design lives, those temporary facilities offer significant cost savings. This is especially true when antiquated infrastructure must be repaired or improved upon to meet Canadian standards (health, safety, fire and environmental). Maintaining infrastructure must allow minimal sustainment costs to be realized and to reduce support personnel levels. Training user personnel to construct, maintain and tear down similar infrastructure develops rapid response to starting the operation, repairs to snags and decommissioning of the camp, regardless of the weather or threat. This minimizes engineer requirements on site, thereby allowing direct supervision of the camp construction versus being the main implementation force. Additionally, user/owner and maintenance personnel can ensure environmental compliance with respect to fuel handling, wastewater treatment, solid waste disposal and noise can be met without difficulty.

Facilities planning for military operations have strict guidelines on area use, utilities, maintenance and protection of personnel. Many of deployments demand the same high standards of living conditions regardless of the climatic conditions: Arctic, temperate, jungle or desert. Guidelines on deployed camp facility planning include the function of the camp, engineer services, siting and military considerations. Operations may require support to airfield operations (fixed and/or rotary), assistance to non-governmental agencies and resupply to other personnel, which impact many of the engineer services.

Site considerations for deployed camps require thorough knowledge of site access, soils, topography, fire prevention, roads, solar orientation, predominant winds, water sources, site security and environmental concerns. Engineering services, in broad terms, of electrical power generation and distribution, water treatment, storage and distribution, wastewater treatment, solid waste disposal, fuels storage and dispensing, heating, ventilating and fire protection. Engineering decisions regarding road construction and maintenance, personnel movement, airfield support and maintenance, warehousing, evacuation planning, medical treatment, and hazardous material handling must be addressed within life expectancy of the camp, camp population/composition and hours of operation.

 

CAMP EUREKA ACCOMMODATIONS/OPERATIONS BUILDING DESIGN

Captain G. Brent Thornhill, B.Sc. (Civ. Eng.) CD

Major Patrick J. Heffernan, Ph.D. (Eng.) P.Eng., CD

A permanent facility within the Canadian High Arctic to house 48 personnel for all seasons and conduct support operations across the upper reaches of Ellesmere Island was required in Eureka (80°00'N 85°54'W). Support to communications, resupply aircraft, survival and sovereignty operations were considered to be the main provisos for the facility. Design conditions within the Arctic are arduous at best but the facility was required to meet several unique conditions. Though the building would be primarily occupied from May to August, it had to be able to support operations at any time of the year with a minimal effort. The development of remote monitoring of the facility from Leitrim, Ontario was to be also considered.

Specific user requirements of the facility were numerous, including 95% reliability of all systems. Medical, airfield and communication support for the surrounding area. Food preparation and storage facilities to support 48 personnel with 28 days of food storage. Exercise and entertainment facilities to encourage off-duty interaction and physical fitness to reduce stress. Utilities operations and general operations of the facility could not depend on attendant maintenance personnel. In fact unskilled labourers and general military skills were the only skill sets available for the operation of the facility whilst occupied. All utility systems had to be able to be turned on and off by the same personnel who occupied the facility. Environmental considerations included wastewater treatment, solid waste disposal and sensitivity to indigenous animals. Survivability of personnel and stores had to be ensured.

Building design had to have total flexibility within the envelope to permit any possible renovations within the building without structural design changes. An integrated expansion capability within the foundation and substructure frame in the event of future expansion was integrated into the building. The utility design was required to meet the needs of 48 personnel with minimal attendance for 3 storm days. More specifically within the envelope, the building had to hold potable water sufficient for 48 personnel on a low-water consumption rate. Self-draining water and wastewater systems improves the survivability of piping and fixtures. An aerobic digester and facultative lagoon forms a minimal attendance wastewater treatment system to permit year-round operation. Electrical distribution of the structure was designed to minimize non-engineer (tradesmen) alterations while maximizing high voltage distribution to increase reliability of critical circuits. Ventilation zone design with a crawl space plenum permits flexibility of use for the 4 defined living areas through heat exchangers, perimeter floor vents and a centralized return system. A boiler heating system (polypropylene glycol-water) design, coupled to the ventilation system permits overall zone control with individual room baseboard heaters. In order to achieve a high comfort level and expedient construction, the architectural finish and accompanying furnishings were selected to be calming and comfortable to personnel while allowing rapid erection with minimal finishing.

 

INFLUENCE OF LOW TEMPERATURE ON THE PERFORMANCE OF THE

BUFFALO POUND WATER TREATMENT PLANT, SASKATCHEWAN, CANADA

By P.T. Srinivasan, T. Viraraghavan and J. Bergman

The toughest treatment period for many water treatment plants is in the cold weather months. This is mainly due to a number of factors such as slower chemical reaction rates and an increased water viscosity at the lower temperatures. The viscosity of water basically doubles as the water temperature changes from the warm summer months to cold winter months. This in reality implies that at colder months i) ineffective coagulation can occur; ii) higher chemical demands may be needed; iii) slower settling rates of particles can be expected; and iv) filters tend to produce high turbid waters. In Canada, the raw water temperature for many water treatment plants may be in the range of 1 - 4°C during winter months and then rise to a range of 15 - 20°C during the summer months. Literature indicates that in cold waters, rate of conversion of monomeric aluminum present in alum (during coagulation) to polymeric forms before precipitation is slow and also produces a floc which is light and disordered due to enclosed water molecules.

The objective of the present study is to examine the influence of temperature on the performance of Buffalo Pound Water Treatment Plant (BPWTP). The BPWTP is a surface water treatment facility supplying water to the Regina and Moose Jaw areas. The treatment plant consists of the following unit operations: prechlorination, rapid mixing, flocculation, sedimentation, rapid sand filtration and activated carbon filtration. During winter months, the activated carbon filters are bypassed. Raw water temperature at the inlet to the plant ranges from 2 to 19°C with a yearly average of about 10°C.

In analyzing the data, the influence of granular activated carbon contactors on the water quality at BPWTP is not taken into account. It is seen that for 1994 to 1996 when the water temperature is less than 5°C (January - March), turbidity removal fluctuates widely in the range of 92 - 80% and when the water temperature increases up to 16°C (in June), relatively increasing trend in turbidity removal (>90%) can be seen. Overall, turbidity removal follows temperature trends. Suspended solids removal follows a similar trend. Percentage dissolved organic carbon (DOC) removals at colder months (<5°C) (January - March; November - December) indicated that removals were less (25 - 30%) compared to removals (45 - 65%) during summer months (water temperature 10 - 15°C). During colder months, total aluminum increased after treatment.

This paper will examine the implications of low temperature on the unit operations and processed of BPWTP.

 

PERFORMANCE OF UASB REACTORS TREATING MUNICIPAL

WASTEWATER UNDER LOW-TEMPERATURE CONDITIONS

Kripa Shankar Singh and T. Viraraghavan

Environmental Systems Engineering, University of Regina, Regina, Canada, S4S 0A2

The feasibility of using upflow anaerobic sludge blanket systems for the treatment of low-strength dilute municipal wastewater under low-temperature conditions was investigated for cold region applications. High-rate upflow anaerobic sludge blanket systems would be an attractive treatment option for wastewaters generated from remote and isolated camps, penal institutions, and winter recreation facilities where connection to municipal sewer systems is either not available or too costly. Domestic wastewater from these sources is generally discharged poorly treated to surface waters and the soil resulting in adverse environmental impacts. It is necessary to provide simple and affordable small treatment systems to alleviate the unhealthy sanitary condition in these remote areas. Moreover, simple operation and construction of the UASB systems makes application of the process feasible for small communities living in remote areas (e.g. Indian Reserves in Canada). This study would offer a possibility to reduce the problem of disposal of wastewaters from remote/rural areas.

In the present investigation, two eight-litre (total volume) UASB reactors (seeded with anaerobic sludge from the digester at the City of Regina Wastewater Treatment Plant) were started-up at 48h hydraulic retention time (HRT) and 20°C. Subsequently, the performance of reactors was evaluated at temperatures of 32, 20, 15, 11 and 6°C and several HRTs ranging from 48 to 3h during the operational periods of more than 800 days. Reactors were fed with the City of Regina municipal wastewater (total COD, BOD and SS ranged from 350 to 600, 150 to 270, and 80 to 250 mg/L, respectively). Under stable conditions, the removal of COD, BOD and SS ranged from 38 to 90%, 47 to 91% and 50 to 92% respectively for low to high temperature range studies. Sulfate concentration in the influent during the stable periods varied between 46 to 70 mg/L sulfur at each HRT and temperature. Sulfate reduction ranged from 10 to 90% showing a decreasing trend with a decrease in temperature at each HRT.

The average biogas production and methane content ranged from 40 to 1,900 mL/d and 65 to 86% respectively.

Mass balance calculations on COD and sulfur revealed that the recovery of methane in the gas phase was very low compared with soluble COD removals, especially during low-temperature operations. Reasons for low methane recovery can be ascribed to the increased solubility of methane at low temperatures which resulted in more than 50% dissolved in aqueous phase and lost in the effluent. Moreover, a major fraction (30 to 40%) of COD consumed in sulfate reduction would have also caused the reduction in methane production. Digital image analysis and scanning electron microscopy revealed the aggregation of biomass which progressed from smooth to flocculent to small granules. The mean size of this aggregated sludge particle ranged from 0.2 to 3.0 mm. Because of good settling characteristics (sludge volume index = 18 mL/g) of these aggregates high sludge retention time could be maintained even at low HRT. This investigation concluded that the UASB systems with some adjustments are technically feasible at a small treatment system for remote camps and small communities in cold regions. The paper will present a design of a UASB treatment system for a small community located in a cold region.

 

EFFECTIVENESS OF RIGID INSULATION IN ROCK TRENCHES

FOR THERMAL PROTECTION OF BURIED WATER PIPES

Lyne Daigle and Jack Q. Zhao

Residents in most parts of Canada may face the potential of their water service pipes being frozen in cold winter months. This problem not only creates inconvenience of losing water, but also incurs unwanted expenses in thawing the frozen pipe. In an effort to find solutions to mitigate the problem, laboratory testing was conducted to investigate the effect of latent heat on the thermal protection of buried pipe. PVC moulds, which represent a rock trench, were filled with clay soils, granular "A" material with an without extruded polystyrene rigid insulation, and granular "A" material mixed with expanded polystyrene beads. Water was included as control. The model trenches were then subjected to -15°C. The embedded thermocouples measured the frost penetration in the model trench. The results show that high moisture content backfill materials showed longer time for frost to reach the centre of the specimen where the pipe would be laid, than low moisture content backfill materials because of the release of heat during water freezing. The use of rigid polystyrene (Styrofoam) insulation material on top and bottom of a pipe actually promoted a faster frost penetration to the pipe location than without the insulation. Numerical model was created using the finite element method, and verified with water in the model trench. The study shows that the rigid insulation material was not effective in protecting the pipe in rock trenches.

HEALTHY HOUSE ON-SITE WATER MANAGEMENT SYSTEM

By Robert A. LeCraw, P.Eng., Phone: 905-853-0626 / Fax: 905-853-8807 / E-Mail: ral@raleng.com, Rolf Paloheimo, Phone: 416-466-5172 / Fax: 416-466-5173, Bill Fandrick, Phone: 867-669-7078 / Fax: 867-873-2348, Chris Ives

The irony of the North is the perception that the abundance of fresh surface water ensures ample supply for communities, resource based industry, and camps. The reality is much different. The adequate treatment and delivery of potable water and the environmentally acceptable collection, treatment and disposal of sewage can be a tremendous financial burden. The cost of delivering water to a residence in the Arctic is approximately 1,000 times greater than in Southern Canada. Innovative solutions appropriate to cold climates are required to ensure an adequate supply of treated water at an affordable cost.

Substantial savings in water and servicing costs can be realized through the use of recycled water. Canada Mortgage and Housing, the National Research Council, and the Government of the Northwest Territories have funded a research project to collect and treat sanitary wastewater to a high quality that may be used for all non-potable uses within a residence. Five demonstration units were installed in Yellowknife in September 1998, one will be installed in Iqaluit in the late fall of 1998, and five in Cape Dorset in the winter of 1998/1999.

 

MARINE TRANSPORTATION,

AN ESSENTIAL SERVICE IN COLD REGIONS DEVELOPMENT

E-Mail: info@mariport.com

Without effective and economic marine transportation, many promising cold region ventures could not be developed. Typically base metal operations will only go ahead if there is marine transportation available to take ore or concentrates to market. Oil and gas ventures suffer much the same problem unless, like the North Slope, pipeline is an option. Even rare metal and gemstone operations can benefit from the reduced cost that marine resupply can offer.

The paper will present a series of brief case studies on cold region marine operations. It will also look at the economics of working with ice capable ships, and risk factors associated with navigation in ice. The potential impact of the Polar Code will be addressed, as will the new ice regime system introduced by Canadian Coast Guard.

Case studies will include: Annual Canadian Eastern Arctic Community Resupply; US North Slope Oil Project; Coronation Gulf Concentrate Transport; Lone Gull Uranium Mine; Polaris Mine; Voisey=s Bay Mine; Canadian Oil and Gas Projects; and Russian Oil and Condensate Transportation.

 

ALTERNATIVE CONCEPTS FOR WATER AND SEWER MAIN

ACCESS IN THE NORTHERN TERRITORIES

K.R. Johnson, M.A.Sc., P.Eng.

B.C. Grieco, P.Eng.,

A study to investigate alternate, less costly access systems for below ground water and sewer main servicing was undertaken by UMA Engineering Ltd. on behalf of the Government of the Northwest Territories. The system most commonly used in permafrost areas of the Northwest Territories and Nunavut Territory is a buried insulated steel access vault.

The study was based on a decision analysis of a number of alternative concepts. Information for the concepts was wasted on a survey of infrastructure access systems in Alaska, the Yukon Territory, the Northwest Territories and the Nunavut Territory. These concepts were then refined, and combined to provide a large number of potential access systems.

A total of 17 alternatives were evaluated using a Kepner-Tregoe Decision Analysis. The evaluation indicated that the three highest ranking alternatives for access to sewer and water mains (in decreasing rank) are:

  • Common below ground mains with insulated steel access vaults.
  • Common below ground mains with insulated High Density Polyethylene (HDPE) access vaults.
  • Separate below ground mains with shallow insulated HDPE water access vaults (requiring a portable shelter), and insulated HDPE sewer access vaults.

 

PERFORMANCE OF SEWAGE TREATMENT SYSTEMS IN

CAMPS AND COMMUNITIES OF THE NORTHWEST TERRITORIES

Ken Johnson, P.Eng.,

Anne Wilson

A variety of sewage treatment systems are utilized for camps and communities in the Northwest Territories region of Canada. The systems vary from conventional mechanical systems to constructed lagoons, natural lakes, wetlands and a combination of systems. The systems number 60 for the individual communities themselves, which does not include the various camp facilities throughout the Northwest Territories.

Information on the performance of these systems has historically been compiled on an inconsistent basis depending upon the available resources, and the opportunity for compliance monitoring by the regulatory authorities. A recent compilation of new system performance data, and historical data from past reports has provided an opportunity to compare the relative performance of various systems. Although the information is limited, it identifies the potential limitations to technologies such as conventional mechanical systems and wetlands systems, and the potential reliability of constructed lagoon systems. The information also defines a database upon which to build for future cold region waste management technology decision making for the regulatory authorities, the mining sector, communities, and the environmental consulting sector.

THE RAGLAN MINE WILL ALSO BE FEATURED IN A TECHNICAL PRESENTATION BY ATCO STRUCTURES INC.

RAGLAN MINE, NORTHERN QUEBEC, CANADA

Frost-shattered boulders dominate the moon-like landscape about 90 kilometres south of Deception Bay in northern Quebec, the home of the Raglan Mine site. The flurry of activity associated with the mine is attributed to the growing demand for stainless steel, which is expected to consume the nickel ore produced.

Here at Katinniq, 61 degrees 39 minutes north latitude on Quebec's Ungava Peninsula, Bechtel Quebec Ltd. is providing engineering, procurement, and construction management services for Falconbridge Limited's Raglan Mine. The work includes building a road and three bridges; a nickel-ore concentrator; a dam to retain spring runoff; and storage facilities to hold supplies and nickel concentrate during periods when severe arctic weather makes access to the site impossible. The conditions are challenging: at an elevation of 600 to 700 metres above sea level, the area's climate is colder and more brutal than Baffin Island, with about 23 frost-free days a year. Average winter temperatures of -30°C can plummet to -50°C. Daily average wind speeds of 30 km/hr can increase to 100 to 120 km/hr during blizzards. Snow drifts wreak havoc during construction, and even the top metre of permafrost (which extends down as far as 500 metres) rarely melts.

The port of Deception Bay, the remote mine site's door to Quebec City, is closed during the October to June winter, when sea ice accumulates to thicknesses of up to two metres. Erratic and severe weather can also thwart aircraft landings.

In 1998, Falconbridge will be reaping the rewards of its half-billion dollar investment ($385 million for construction and $120 million for mine development) as the mine starts processing 800,000 metric tonnes of nickel ore per year and producing up to 130,000 metric tonnes of nickel-copper concentrate annually, valued at about U.S. $100 million. While typical mines have a life span of up to 15 years, this mine may be around for 25 years because of its rich ore bodies.

Technically speaking, the problems of design were the same as elsewhere, but they were compounded by further constraints. All the piles for the foundation work were fairly simple, except the temperature of the rock is at -6 to -7°C. Special concrete and grout to hydrate and set at these sub-zero temperatures was developed for the project.

The impact of global warming, and the associated risk with the various structures of the project, was also used in the geotechnical analyses, assuming that there could be a half-degree Celsius increase in temperature every 10 years. While the Raglan project has a potential life span of 25 years, the permafrost engineering used a design life of 50 years. Since Raglan is the first Quebec mine to undergo environmental impact assessments, feedback about the project's effect on the sensitive northern environment was sought from aboriginal and non-aboriginal communities.

This is not the first time that mining operations have flourished on the Ungava Peninsula. Years earlier, an asbestos operation thrived at Asbestos Hill, about 35 kilometres from Katinniq. The abandoned road built to service Asbestos Hill was upgraded to become a transportation link to the Raglan site, and another 60 kilometre road was constructed. A facility to house a 100 person mining-exploration camp was established in 1991, was used to house workers until the accommodation complex was built.

In 1996, the water reservoir (for domestic and process use); and the accommodation, service (vehicle maintenance) and, administration buildings were completed. The accommodation complex, designed to serve 300 mine workers, has a central area with a cafeteria, full recreational facilities including a games room, exercise area, bowling alley and a whirlpool, and is connected to the service and office building by an elevated walkway.

The maintenance of the permafrost was taken into account in the design of these buildings using the common practice of building on pile foundations. A pile foundation system was used for the accommodation complex, which rests on stilts one to two metres above the ground surface. This separation allows the wind to circulate under the structure, preventing snow build-up and dispersing the heat from the building to keep the permafrost layer from melting, and causing settlement problems. The service and administration building's floor is a concrete slab resting on a gravel pad with ducts installed beneath the building to prevent melting of the permafrost. When the air temperature is colder than the ground temperature, large fans direct colder ambient air through these ducts to keep the permafrost layer intact.

Permafrost may also be a help rather than a hindrance in some cases. The design of the dikes for containing acid-generating waste rock incorporated permafrost as a low permeability barrier.

During the summer of 1996, while the piles and foundation for the ore concentrator were constructed at Katinniq, the construction of 12 modules - two for the diesel-fuelled power plant and ten for the ore concentrator - began at a construction yard on the St. Lawrence River near Quebec City. By the spring of 1997, the massive cube-shaped modules, weighing between 900 and 1,200 tonnes, were ready for transport. Early in July, the first of two tug-towed barges began the two-week trip to Deception Bay carrying the first seven modules. The remaining five units left later in the month.

Once the modules arrived in Deception Bay, they were moved to 24-axle flat-bed trailers, which took more than two days to make the 95 kilometre journey to the Raglan site, travelling at two to three km/hr. Concerns about high winds causing problems with transporting the 20 metre tall structures turned out to be unnecessary, and the modules arrived six days ahead of schedule.

The Raglan Mine is a modern example of Cold Region resource development, which takes into account the environmental and social aspects, as well as strictly technical aspects of working in a northern latitude.

THIS ISSUE FEATURES AN EDITED ARTICLE ON CANADA'S CRISIS IN ARCTIC SCIENCE: THE URGENT NEED FOR AN ARCTIC SCIENCE AND TECHNOLOGY POLICY; OR, "WHY WORK IN THE ARCTIC? NO ONE LIVES THERE"

The complete article was published in Arctic, the Journal of the Arctic Institute of North America, June, 1998.

Authors

John H. England, Arthur S. Dyke and Gregory H.R. Henry

John H. England is a professor in the Department of Earth and Atmospheric Sciences, University of Alberta.

Canada has entered a deep crisis in Arctic science. The lack of a formal Arctic Science and Technology Policy has left our highly fragmented efforts in Arctic research exceedingly vulnerable during times of financial stress and left us effectively without a voice. Logistical support, essential for operating in our vast northern territory, has all but disappeared as a facilitator for both government and university research. Within two years, only specially funded research will be possible, and the Arctic science community must alert the government to take action. If nothing is done to secure its future, Canada's capacity to perform Arctic research will collapse.

THE FEDERAL ROLE

The most telling sign of diminishing commitment to northern research in Canada has been the progressive withdrawal during the past decade, of all major research agencies within the Federal Government. Traditionally, these agencies have constituted the core of northern research, housed mainly in the departments of Environment, Fisheries and Oceans, and Natural Resources, with the latter playing a key role through the Polar Continental Shelf Project (PCSP). Our primary research agencies have included the Atmospheric Environment Service, the Geological Survey of Canada, the Canadian Hydrographic Service, the Canadian Wildlife Service, Health Canada, the Canadian Museum of Nature, and the Canadian Museum of Civilization. These, along with university researchers from all disciplines, have been served logistically by the PCSP. Concurrently, the government agencies have routinely spun off substantial support for university collaborators, particularly for graduate students, in informal but effective synergies that enhanced university research capacity in the Arctic greatly beyond what would otherwise have been possible. This support also served to build numerous bridges between federal scientists and academia that facilitated cooperative programs and diminished unproductive rivalries.

In the process of downsizing federal science, Canada has dismantled much of the infrastructure necessary to pursue and promote our national and international responsibilities in our own backyard. By eliminating hundreds of scientists from federal laboratories, we have created a science-employment environment that has diverted, and continues to divert, students away from science. No one appears to be measuring these effects, but the reality is evident. Increasingly, so many young Canadian PhDs are moving to the United States or Europe that many professors ask whey they still bother training scientists at the taxpayers' expense. Someone should answer - carefully.

Arctic research was especially hard hit because it was, and is, seen to be more expensive. Many managers seem to have surrendered to this charge. Yet, we are unaware of any comparative cost-benefit studies of Arctic versus southern research.

What are the long-term costs to Canada of eliminating the Arctic scientific capacity it paid to create over the last 50 years? When the inevitable next "national imperative" (an energy crisis, for example) pushes us back into the Arctic on short notice, what price will we pay for the lost corporate and scientific memories? In the natural sciences, it commonly takes an individual half a career to develop his or her best set of research questions. Persistence and continuity are indispensable.

Expense has not been the only objection. "Why work in the Arctic? No one lives there," said a former head of the Geological Survey of Canada, who - apparently on no stronger argument that this - rendered all Arctic research in that agency basically irrelevant. It is seemingly impossible to defend a program against such a stance, or at least, in this case, defence was unsuccessful. Unfortunately, our impression is that the success of Arctic research in Canada has relied all too often on the good graces of a handful of individuals who were favourably disposed towards the importance of the Arctic. Such reliance left it vulnerable to those who were not.

There is also a fundamental ethical issue here regarding Canada's relationship to its Arctic territories: is it appropriate for Canada to take an interest in Arctic science and in the environment only when opportunities for exploitation of natural resources by southern or foreign interests loom large, or only when such exploitation seems necessary for the good of the nation? This is a rather colonial attitude. Yet the current spurning by federal agencies of long-term Arctic science, not so much by choice as by economic necessity, sends exactly this message. Most appreciate that basic scientific problems, including those like global change with particularly strong and recognized Arctic relevance, can only be addressed in the long term. Still, acceptance of this fact does not secure support for the research.

UNIVERSITY RESEARCH

In comparison to our neighbour to the south, a greater proportion of Canadian science has been done in federal laboratories. Assuming this is undesirable, a new balance might have been struck by shifting resources to the universities, using a carefully planned strategy designed not to diminish our overall capacity. Unfortunately, however, Canadian universities and federal science departments experienced downsizing simultaneously. The combined result has been a massive retirement and deportation of Canada's scientific human resource base. One can only be confused, therefore, by statements in the last federal budget that announced an impending shortfall of scientific talent a decade down the road, while deliberate steps continue to be taken to reduce Canada's science capacity.

The funding crunch for university research has resulted in a steep decline in applications for logistical support to PCSP during the 1990s, from a high of 70 projects down to 40 this year. Government projects have declined even more severely, by close to 50%. In 1980, PCSP actually supported 166 field parties and this number grew to a high of 250 parties during that decade.

In the meantime, our established community of northern scientists is aging and retired, or retiring younger. Upcoming researchers face fewer opportunities. As confidence in Canadian prospects of funding and logistical support for northern research continues to erode, it comes as no surprise that few will risk their futures by investing in northern careers. Hence, academic recruitment in Canada for northern research has reached alarmingly low levels and a compelling option, if not a necessity, for anyone with northern interests is to head to the United States or Europe. Indeed, few Canadian universities are recruiting Arctic specialists today, possibly because the chances of building a program attractive to the university are so daunting. Or our southern universities themselves may simply have lost interest.

Canada now faces a crises in northern research (and perhaps research in general) that, if left unchecked, will ensure our failure to train and support the next generation of scientists and lead to a collapse of Canadian scientific sovereignty. We will then be unable to meet basic national obligations to adequately monitor, manage, and safeguard our environment, let alone to take a leadership role or to strongly contribute to issues of international importance. It is already much more common to hear science about Canada from others at international meetings than it is to hear Canadian science. But, to be perfectly clear about what we think is wrong here, it is not the attention of our neighbours and friends. Indeed, we suspect that Americans who are sensitive to this issue go out of their way to include Canadians in their programs, allowing the problem to seem less severe than it is.

LEARNING FROM THE FRIENDLY GIANT

While Canada has been dismantling Arctic research, the United States has demonstrated a renewed commitment through rigorous legislation, strong funding, and required interagency cooperation. A comparison of the two countries in Arctic matters reveals American vision towering over Canadian indecision and parsimony, and the consequence is opportunity and leadership versus unemployment and ever-dwindling significance. Surely this cannot be because Arctic research is less relevant to Canada! It is the saddest form of flattery when we are informed that the recent American initiative arose from the pleas of American scientists, familiar with PCSP, who sought, in part, to emulate our success in Arctic research.

In northern matters, Canada suffers even more from a lack of leadership than from a lack of resources. Therefore, given Canada's reluctance to take a fully integrated, leadership role in the Arctic, it is instructive to look closely at what is clearly an extremely progressive American lead.

Anyone concerned with the plight of future direction of northern research in Canada should read the Fifth Biennial Revision (1998-2002) of the U.S. Arctic Research Plan (IARPC, 1997). It is evident that it is "the result of an extensive process of planning, consultation and revision" (p.4). The Plan outlines national needs (nonrenewable and renewable resources, global change, social and environmental issues), a broad range of special focus multiagency research programs, and a host of agency programs. The total interagency funding for fiscal year 1997 was US $172 million, and for 1998 it is US $156 million. A selection of agencies includes the Department of Defence, the Department of the Interior, Department of Energy, National Aeronautics and Space Administration, and the National Science Foundation, which includes the Office of Polar Programs. The multiagency programs stand out for their breadth and depth, and include issues such as risks to the environment and people in the Arctic, surface heat budget of the Arctic Ocean, Beringian systems studies, and Arctic data and information. The multiagency Beringian study could just as easily describe the Canadian Arctic Archipelago, emphasizing that this region is "emerging as a major international arena for interdisciplinary study of scientific issues and global change with historical and modern perspectives". It emphasizes the fundamental importance of "baseline data and monitoring" .

Simply put, the scope, integration, and support for Arctic research in the United States is enormous. And make no mistake, it is based rigorously and thoughtfully upon established principles and objectives. There is no indecision here! No suffocating parsimony. It seems to us that Canada at this point has two choices: rely entirely on the United States for all Arctic science (contracts would probably be welcomed) or seriously acknowledge its own geographic identity and behave accordingly.

WHITHER PCSP: NOT AFFORDABLE AT 20 CENTS PER CAPITA PER YEAR!

It is important here to return to and to make clear the plight of the Polar Continental Shelf Project. It highlights the contrast between U.S. and Canadian Arctic strategies, and it effectively shows the urgency and the extent of our crises.

PCSP, currently celebrating its 40th anniversary, was established by Act of Parliament in 1958, as part of Prime Minister Diefenbaker's "northern vision". It was visionary, it has been gloriously successful, it has fostered most of Canadian Arctic research and assisted non-Canadian research. PCSP started out as a bold and innovative solution to the scientific field requirements for exploring the vast and diverse Canadian Arctic Archipelago and adjacent continental shelf. Its successes, ingenuity, and efficiency are a monument to the dedicated efforts of its directors on behalf of Canadian polar science. It is now entirely a logistical operation, but a seasoned one, based in Ottawa with facilities in Resolute Bay (High Arctic) and Tuktoyaktuk (western Arctic; now dormant). Each spring and summer it has operated chartered aircraft (Twin Otters, helicopters) that provide the coordinated logistical support for staging and evacuating fly (tent) camps widely dispersed throughout the northern mainland and islands. Principally, it has operated north of the Arctic Circle. PCSP supports scientists from both universities and government research agencies who, for the most part, live frugally while investigating everything from archaeology to zoology, to borrow George Hobson's expression. At its peak during the 1970s and 1980s, PCSP had a budget of around Cdn. $6 million, largely dedicated to logistics. Only three years ago, it was further evaluated for its perceived usefulness to its clients: the government evaluators reported that they had never seen such high praise in 30 years of assessment! Despite such glowing recommendation, despite its extremely modest budget (20 cents per Canadian per year at its peak), despite being indispensable to its clients, despite the fact that it makes a Canadian presence in Arctic research possible, and despite its astonishing success in safety and efficiency, its budget has been cut progressively and it now struggles to survive.

Despite the political interest, by 1999 PCSP's budget for its entire Arctic field operation will drop to about Cdn. $1 million (US $710,000; approaching one-sixth of peak funding, without correction for inflation). The NSF-funded PALE Project (Paleoecology of Arctic Lakes and Estuaries) has a Steering Committee budget of US $600,000. Soon PCSP will be able to offer only a meager Cdn. $250,000 (US $178,000) for the entire Canadian university community. About one-third its level of only three years ago, this amount would fall within the range of a single modest NSF project. A recent report from an Arctic institute at an American university lists nearly US $20 million in current research grant holdings for that institution. At Cdn. $1 million per year, PCSP's logistical operation costs Canadians about 3 cents per citizen per year, less than the GST on a 50 cent chocolate bar! Compared to the present U.S. Arctic research commitment, PCSP, which started out so bold and gave us such pride, now looks like a rusted-out VW Beetle with four flat tires eclipsed by the gleaming technology of the space shuttle. This contract cannot be dismissed as due solely to economies of scale; to a large degree, it is due to Canada's economy of self-betrayal.

The crises for Arctic research in Canada is thus obvious. The overall effect of our collective failure, however, will also be much greater than the straight percentage reduction in support because the overall reduction in the synergy and caliber of Arctic research will be much greater as critical mass is lost. The political danger here is that it becomes easy to misconstrue the diminished ranks of university applicants and number of government projects as expressions of diminished scientific interest and low relative importance of Arctic science to the nation. Nothing could be further from the truth, but saying this will not solve the problem.

LOOKING AHEAD

What we present here echoes the thoughts of many Arctic researchers who are struggling to find signs of hope on Canada's horizon. The Government of Canada strongly supported the establishment of the Arctic Council, and the government's commitment to conservation under the Arctic Environmental Protection Strategy clearly requires an ongoing contribution from Canadian scientists. The Standing Committee on Foreign Affairs and International Trade (SCFA) recommended that "the Government commit to maintain, and seek to increase, support for basic Arctic science and research as an important element of circumpolar cooperation." It effectively sets aside the "expense" argument in stating that "the cost of Canada's [Arctic] research was never high in comparison to the amounts spent by other Arctic states". It validated the argument advanced to it by Michel Allard that "Canadian scientific research in the North produced, especially from 1950 to 1989, . . . spectacular results with investments that were in fact far inferior to those made by the major powers."

So where can we go from here? Clearly it is intolerable to languish in our present state. Therefore, as an idea for discussion by the Canadian Arctic science community, we resurrect here the proposal that Canada establish a Canadian Polar Institute. This institute would effectively house and coordinate our national goals and expertise in Arctic social and natural science, technology, logistics (PCSP), and policy. It should be a real (as opposed to a virtual) institute, where people can gather and interact.

It should be established by an Act of Parliament, and set firmly upon principles and objectives included in an Arctic Science and Technology Act. International cooperation with other Arctic institutes and agencies would be an implicit objective. We can see no other way to safeguard Arctic research and its essential infrastructures in times of intense funding stress. A Canadian Polar Institute could also play an indispensable role in planning and coordinating future Arctic research.

We emphasize the need to collect, coordinate, and streamline existing Arctic interests in a new Polar Institute. Coordination of logistics must now be matched by coordination of research to demonstrate optimum efficiency. To facilitate the greatest efficiency and expertise in Canadian Arctic interests, the Institute should house both the PCSP and the Polar Commission. PCSP could then be fundamentally rejuvenated and tethered to a strong, mandated, research agenda. The Polar Commission would continue to act as the nation's premier Arctic-Antarctic policy adviser, and it would continue to promote public awareness of the North. The Polar Commission would have the added advantage of continuous and direct access to an active scientific community. Similarly, the Arctic scientific community would benefit from the broader perspectives of the Polar Commission, including its First Nations members, who could strongly influence research agendas. Finally, the Institute would promote appropriate linkages with Canada's three northern territories and with First Nations organizations in the arctic regions of the provinces, primarily Labrador and arctic Quebec.

THIS ISSUE FEATURES INFORMATION ON THE 1ST COLD REGIONS SPECIALTY CONFERENCE OF THE CANADIAN SOCIETY FOR CIVIL ENGINEERING SCHEDULED FOR JUNE 3 TO 5, 1999 IN REGINA, SASKATCHEWAN. FOR REGISTRATION INFORMATION CONTACT KEN JOHNSON.

1ST COLD REGIONS SPECIALTY CONFERENCE OF THE COLD REGIONS ENGINEERING DIVISION OF THE CSCE

The Cold Regions Engineering Division (CRED) of the CSCE has been an official Technical Division of the Society since 1986. The Division has maintained a relatively low profile with regard to technical activities because of the limited human resources of the Division members. The Division has, however, participated in the publication of several milestone documents, most significantly the Cold Regions Utilities Manual. The Manual was updated in 1996 through the lead efforts of Dr. Dan Smith in association with the ASCE Technical Council on Cold Regions Engineering.

The 1st Cold Regions Specialty Conference of the Cold Regions Engineering Division represents a milestone event for the Division in undertaking a high profile activity within the Society. This is also a very exciting time for a Cold Regions Specialty Conference to occur in Canada. The formation of the Nunavut Territory in 1999, the transportation related studies occurring in the NWT, and the start-up of the first diamond in North America represent the so-called "tip of the iceberg" in ongoing activity in the Canadian North.

The idea for this conference may be traced back to a relaxing evening in August, 1997 at the Department of National Defence (DND), Eureka Camp in the high Arctic (80 degrees North Latitude). Jean Heroux and Ken Johnson were enjoying after dinner conversation with the Camp staff, and marveling over the local activity associated with the Camp construction. This included the reconstruction of the DND Eureka Camp, the proposed reconstruction of the Environment Canada Eureka Camp down the road, and the construction of the Astrolab Observatory perched on the adjacent hills more than 15 kilometres from Eureka. Out of this discussion a Specialty Conference on Remote Camps was born.

The Cold Regions Specialty Conference promises to be an interesting event with a variety of technical presentations on remote camp facility design and construction, waste management for remote camp facilities, and remote camp facility resupply. Amongst these theme related technical presentations will be a variety of other Cold Regions Engineering related technical presentations.

Thirteen technical presentations are expected at the conference. The range of the technical presentations, relating to design, construction and research on remote camps, and other cold regions related activity, is going to provide a very notable opportunity to discover the science and the application of remote camp technologies.

A panel discussion on Environmental Management for Remote Facilities is also scheduled for the end of the conference. Panel members will include representatives of government, industry and consulting.

The conference is endorsed by the Department of National Defence, the Royal Military College of Canada, the Government of the Northwest Territories, the Department of Indian and Northern Affairs, Environment Canada, and the Nunasi Corporation.
