• Alaskan water resources: Selected abstracts, 1974

      Hartman, Charles; Finch, Sheila (University of Alaska, Institute of Water Resources, 1977-02)
      As one of the 51 Water Resources Research Institutes administered under the Water Resources Research Act of 1964, IWR receives a semimonthly journal entitled Selected Water Resources Abstracts. The bulletin, published by the Water Resources Scientific Information Center (WRSIC) of the Office of Water Research and Technology, includes abstracts of documents covering the water-related aspects of the life, physical, and social sciences as well as related engineering and legal aspects of the characteristics, conservation, control, use, or management of water. Each abstract in the bulletin is classified into 10 fields and 60 groups of water research categories (see page iii). In addition, the journal contains a subject, author, and organizational index. In an attempt to keep interested parties abreast of the research being done in water resources in Alaska, the Institute of Water Resources is planning to publish yearly all abstracts listed under the subject index "Alaska." This report covers all citations for 1974.
    • Analysis of Alaska's water use act and its interaction with federal reserved water rights

      Curran, Harold J.; Dwight, Linda Perry (University of Alaska, Institute of Water Resources, 1979-02)
      Since the passage of Alaska's Water Use Act in 1966, the amount of water required by Alaska's growing population and resource development has increased very rapidly. The need to review the adequacy of existing water use laws and their administration has been expressed both by those trying to comply with regulations and by those attempting to enforce standards and permit requirements. This report summarizes the historical development of the doctrine of prior appropriation in Alaska. The statutory authority, regulations, and administration of Alaska's Water Use Act by the Alaska Department of Natural Resources are presented. Overlapping state agency authorities are discussed, and existing and proposed regulations are analyzed. The application of federal reserved water rights to Alaska and the status of quantification of these rights is explained. The report presents options for the State of Alaska to manage water use on federal lands, and for preserving minimum stream flows for maintenance of fish and wildlife habitats.
    • An Analysis of the Demands for Water from the Private Sector in a Sub-Arctic Urban Area

      Haring, Robert C. (University of Alaska, Institute of Water Resources, 1972-04)
      Manufacturing and domestic uses of water are very important to local communities throughout Alaska, although manufacturing typically represents relatively high levels of consumption in terms of population use equivalents. This study is concerned principally with the present water use practices and associated problems in the private sector of the North Star Borough, Alaska.
    • Annotated Keys to the Genera of the Tribe Diamesini (Diptera: Chironomidae), Descriptions of the Female and Immatures of Potthastia iberica Tosio, and Keys to the Known Species of Potthastia

      Doughman, Jan S. (University of Alaska, Institute of Water Resources and Engineering Experiment Station, 1985-08)
      A review of available information on the tribe Diamesini led to the construction of generic keys to most life stages. Serra-Tosio (1971b) first described Potthastia iberica from an adult male from the Spanish Pyrenees. Evaluation of specimens collected in the Nearctic, from Idaho (in 1967) and Georgia (in 1981 and 1983), indicate that this species is extant in eastern and western highland streams that appear to be typical trout streams. This new group of specimens contained a mature male and female pupa and immatures, and associations made it possible to describe the female and the immatures for the first time. Adult specimens conform very closely to the holotype. The known species of Potthastia are keyed.
    • Annual report of research progress

      MIRL (University of Alaska Mineral Industry Research Laboratory, 1969)
      The great importance of minerals to a state's sound economy can be no better illustrated than by the discovery of oil and gas in Alaska in 1957 in the Kenai Peninsula. This event has led to the establishment of local basic and secondary industries which in turn will enrich the coffers of the state. In a parallel manner, the discovery of oil and gas on the North Slope in 1968 will not only produce basic and allied industries but will also be a catalyst assisting the development of other mineral resources to provide a diversification of industry--so important to the long range economic strength of a state. Also, further economic development of mineral resources is, to a large degree, dependent on mineral science research in the same way that research and development were necessary to develop the jet engine and hence, give a break-through in air transportation; thus, without geological and mineral processing research, mines cannot continue to be found and developed. The following pages will provide evidence of a significant contribution toward the shortening of the knowledge gap in mineral search instrumentation, gold size distribution, coal processing, prospector education, resource evaluation, and exploration oriented computer techniques. The demand by the Alaskan public, industry, and governmental agencies for this information has justified the reprinting of several of this year's research reports. This response by industry and the public has given increased impetus to the goal of MIRL: to aid in the expansion of Alaska's mineral economy through a program of applied and basic research--to seek knowledge today for use tomorrow.

      MIRL (University of Alaska Mineral Industry Research Laboratory, 1966)
      The mineral and human resources of a state and/or nation are to a large extent the basis of a strong and flourishing economy. In Alaska this is currently illustrated by the activities of the oil and gas industry and the resulting large sums of money that have gone into the state Treasury to help give a sound financial basis to Alaska. The Mineral Industry Research Laboratory has concentrated its efforts on research that will help in the more complete utilization of Alaska's mineral resources for work in the state's mineral industry. This report describes in moderate detail the projects that have been undertaken. These are in the areas of mineral economics, exploration, mining, mineral benefication, beach and ocean mining, utilization of nonmetallics, use of coal resources, and the solving of numerous' specific problems posed by mining people of the state. Training of young men and women for the mineral industry is stimulated by their having the opportunity to work on projects as a part of their graduate program under the supervision of the staff of MIRL. Theses completed offer a considerable amount of information to the public. Recent completed theses are listed in this report. The laboratory has been supported financially by the state of Alaska and various grants and work in kind from individuals and agencies. Private industry has helped in purchasing equipment and cooperative projects are underway with government agencies. Personnel and facilities of the College of Earth Sciences and Mineral Industry supplemented by other professional personnel are involved in teaching and research as set forth in enabling legislation for the Laboratory.

      Continuous research is the key to problem solutions and also to new developments in winning minerals from any environment, be it the land, the air, or the sea. Strong research programs yield both present and future benefits and are part of any vigorous, dynamic development. In Alaska, new mineral deposits must be searched for; marginal and submarginal deposits must be reviewed in terms of sophisticated methods of mining, benefication and extraction; and greater utilization must be developed for Alaska's industrial minerals, fuels, and off-shore mineral deposits. Continuous research, directed toward solving problems of present mineral production and uses, yields a technology which will solve future problems, and is essential if a vigorous mineral industry is to continue to play its basic role in Alaska's growing economy. Since mineral resources are of limited value without human resources, the Mineral Industry Research Laboratory is also dedicated to the development of Alaska's young men and women for careers in the mineral industry.

      MIRL (1967)
      This year the Mineral Industry Research Laboratory has concentrated its efforts on projects relating to the more complete utilization of Alaska's mineral resources. This report briefly describes the projects that have been undertaken. These are broad in scope including topics such as mineral economics, exploration, mining, mineral beneficiation, beach and ocean mining, use of coal resources, resource evaluation, and market research analysis. Studies have been undertaken which investigate problems or topics in nearly all areas of the state, including Southeastern Alaska, Anchorage area, Northern Alaska and the Fairbanks area. In the future the MIRL Annual Report will be presented on a fiscal basis. To bridge the gap this year, an addendum to this report will be prepared in the Spring.

      MIRL (1964)
      Research that will lead to the utilization of Alaska's mineral resources and hence create new wealth must be 1::ontinued at an increased rate in the future if a strong mineral industry is to be developed and maintained. Current investment in minerals research is a judicious practice that will pay dividends to the State in the future. The Engineering Council for Professional Development, in their 1964 report which continued the accreditation of the engineering curri1:: ula at the University of Alaska, emphasized this concept when they stated: ''Regardless of the mining industry's present size, the State clearly needs a mining center in its State University not only for teachi} 1g but also for research and for service to prDspectors and mine operators." The Mineral Industry Research Laboratory is dedicated to those objectives of research, instruction and service which will help build the mineral economy of Alaska.

    • Applicability of siberian placer mining technology to Alaska

      Skudrzyk, F.J.; Barker, J.C.; Walsh, D.E.; MacDonald, Rocky (University of Alaska Mineral Industry Research Laboratory, 1991)
      The result of Perestroyka and Glasnost has been an awakening of potential for cooperation between East and West. Nowhere has that been better demonstrated than between Alaska and Magadan Province, USSR. This report summarizes a one year effort financed by ASTF, with participation from several technical organizations, to establish contacts with the Siberian placer mining industry. The purpose of the project was to provide initial assessment of the Soviet technology for placer mining in permafrost. A ten day trip to Magadan province by an ASTF team and a similar length visit to Alaska by the Soviet mining group representing the All Union Scientific and Research Institute of Gold and Rare Metals, (VNII-I), Magadan are described. The report also reviews translated data on mining in permafrost and describes surface and underground placer mining technology developed by the Soviets. The report also lists relevant publications on Soviet mining research and state of the art Soviet mining technology and expertise.
    • Application of Artificial Recharge Technology for Managing the Water Resources - Anchorage, Alaska

      Guymon, Gary L. (University of Alaska, Institute of Water Resources, 1972-06)
      The purpose of this report is to explore the usefulness of artificial recharge in Alaska where there are significant known water supply problems, specifically Anchorage, Alaska. More importantly, however, this report is intended as a vehicle for updating what is known about artificial recharge and for making this information available to water resources agencies and water supply planners in Alaska. The report is not intended to be an original scientific research but is a synthesis of new knowledge developed by the writer and others within the last half-decade. This report concentrates primarily on artificial recharge by off-stream basins in an effort to narrow what is a rather broad field. The concepts discussed under this restricted heading, however, are generally applicable to other recharge methods such as on-stream artificial recharge. Artificial recharge by basins is defined for purposes of this report as the practice of ponding water in constructed off-stream ponds with the explicit intention of allowing water to infiltrate into the underlying aquifer.
    • Application of hydrocyclones for recovery of fine gold from placer material

      Rao, P.D.; Wolff, E.N.; Maneval, D.R. (University of Alaska Mineral Industry Research Laboratory, 1982)
      Alaska and other gold areas have seen a sharp resurgence of placer mining in the last few years. Mines using sluice boxes usually recover gold down to 100 mesh, but recovery of gold finer than this size is a function of particle shape factor, sluice box design and operating parameters. It is felt that a concentrating device is needed to recover gold finer than 100 mesh that may not be recoverable in a sluice box. The device should be capable of processing a large volume of water and solids discharged from the sluice-box. Compound water cyclones, successfully used in the coal processing industry, seem to offer solutions. A system using these devices could recover a concentrate which would be one twenty fifth the size of the original solids in a two stage process. It is not intended to produce a finished product with cyclones, but to reduce bulk so that the reduced concentrate, free of slimes, could further be treated by flotation, gravity methods, or cyanidation to isolate the gold. This report addresses only the application of hydrocyclones for concentrating gold from placer material.
    • Application of hydrocyclones for the treatment of wastewater in gold placer mining

      Lin, H.K. (University of Alaska Mineral Industry Research Laboratory, 1980)
      This is a report on experimental application of hydrocyclones for the wastewater treatment in placer mining, with emphasis on their use in combination with a kind of large molecular weight flocculant. The simultaneous flocculating and clarifying of placer mining effluents was tested and evaluated.
    • Application of palynological techniques for correlation of coal seams in the Lower Lignite Creek area, Nenana Coal Field

      McFarlane, R., Sanders, R., and Rao, P.D. (University of Alaska Mineral Industry Research Laboratory, 1980-03)
      This study concerns spores and pollen in the coals of the lower Lignite Creek area in the Nenana Coal Field, which is operated by Usibelli Mining Company. The seams studied are part of the Suntrana Formation which contains a large portion of the coal reserves of Nenana coal. These coals are mid-Miocene in age and are separated from each other by cyclic sandstone, clay and silt deposits, which reflect alternating periods of coal forming swamps and depositing streams. A preliminary study of the mega and micro botanical fossils of this area was made in 1969 by Wolfe and Leopold (Wahrhaftig et al, 1969). Palynological investigation was done on 26 samples of the Suntrana Formation and evidence from this and fossil leaves indicate that the formation should be placed in the Seldovian stage.
    • Application of portable delayed neutron activation analysis equipment in the evaluation of gold deposits

      Sims, J.M. (University of Alaska Mineral Industry Research Laboratory, 1980-03)
      The attributes of a gold analysis system which could act as a panacea for the needs of the explorationist and the miner alike would include: i) The capability of being used as a qualitative as well as a quantitative tool yielding accurate results in respect of large samples. ii) The capability of generating results on site either in the field or within a prospect or mine. iii) An identifiable cost effectiveness in relation to other methods. iv) The capability of being housed in an equipment package which combines ruggedness, portability and reliability with operational options which permit measurements to be made on outcrops, mine faces, borehole cores as well as direct in-situ down-the hole determinations. The portable x-ray fluorescence gold analyser is on the threshold of meeting all the criteria cited above. Since the system is non-destructive in so far as the sample is concerned check assays employing conventional techniques can be run on a small percentage of the sample population. This report by its very nature is a state of the art review which sets out to describe the current instrument package, the principles by which it functions, its performance compared with detailed chip channel sampling and then suggests how the system may evolve in terms of its application to the investigation of hard-rock and placer deposits.
    • Application of the Finite-Element Method for Simulation of Surface Water Transport Problems

    • Applications of trend surface analysis and geologic model building to mineralized districts in Alaska

      Heiner, L.E.; Wolff, E.N. (University of Alaska Mineral Industry Research Laboratory, 1967)
      The Mineral Industry Research Laboratory, University of Alaska, has investigated the application of computers and statistics to mineral deposits in Alaska. Existing programs have been adapted and new ones written for the computers available at the University. The methods tested are trend surface analysis and geologic model making. An existing coeffecient of association program was converted to Fortran IV , but was not applied to an Alaskan problem. A trend surface is a mathematically describable surface that most closely approximates a surface representing observed data. In geologic model making, regression analysis is used to determine what geologic features are significant as ore controls. Coefficient of association compares samples to each other on the basis of a variable being present or absent. Trend surfaces were computed for dips and s t r i k e s of geologic features ( v e i n s , f a u l t s , bedrock) for Southeastern Alaska, the Chichagof district , and the Hyder district . Results for the f i r s t two are presented as maps. Trend surfaces and residual maps were prepared for geochemical data from the Slana district, Alaska. A mineral occurrence model was made for a portion of the Craig Quadrangle, and potential values were computed for c e l l s in the area. Appraisals of potential values by five geologists are compared with those of the model. An IBM 1620 multiple regression program is included.
    • Arsenic in the Water, Soil Bedrock, and Plants of the Ester Dome Area of Alaska

      Hawkins, Daniel B.; Forbes, Robert B.; Hok, Charlotte I.; Dinkel, Donald (University of Alaska, Institute of Water Resources, 1982-06)
      Concentrations of arsenic as large as 10 ppm (200 times the safe limit for drinking water) occur in the groundwater of a mineralized residential area near Fairbanks. Bedrock of the area contains 750 ppm As, primarily as arsenopyrite and scorodite. The oxygen-poor groundwater is enriched in As(III) and ferrous iron while the surface waters are iron free and contain less than 50 ppb As(V). Arsenic is removed from the water by coprecipitation with ferric hydroxide. Some iron-rich stream sediments contain as much as 1,400 ppm arsenic. The distribution of arsenic in the groundwater is controlled by the distribution of arsenic in the bedrock. The arsenic content of the B soil horizon over mineralized veins is about 150 ppm, while that over barren rock is 30 ppm. The vegetation over the veins is not significantly enriched in arsenic. Lettuce, radishes and tomatoes grown with arsenic-rich water (5 ppm) contain 16, 8 and 1 ppm As, respectively; these amounts are significantly greater than plants not treated with arsenic. Preliminary studies by state and federal health agencies show no detrimental effects on the health of persons drinking these arsenic-rich waters.
    • An Atmospheric carbon monoxide transport model for Fairbanks, Alaska

      Carlson, Robert F.; Fox, John (University of Alaska, Institute of Water Resources, 1976-06)
      A comprehensive computer model of atmospheric carbon monoxide transport has been developed for Fairbanks, Alaska. The model, based on a finite element method computational scheme, accents input from specified vehicle traffic parameters inc1uding miles per day, number of cold starts, and total idle time. The carbon monoxide concentrations are calculated for specified time intervals at numerous points throughout the urban area. A test of the model against the data of January 22, 1975, indicates a good correspondence. Extremely high carbon monoxide concentration were calculated at an unmeasured point down wind of the business district. The model should prove useful for a number of community needs including parking management, planning and zoning, episode strategy planning, and carbon monoxide forecasting.
