A Town Meeting on Energy : Prepared for Interior Alaskans

On March 26, 1977, an all-day Town Meeting on Energy was held at the Hutchison Career Development Center on Geist Road in Fairbanks, Alaska. This event was sponsored by the Alaska Humanities Forum in cooperation with the Fairbanks North Star Borough School District; the Institute of Water Resources at the University of Alaska, Fairbanks; and the Fairbanks Town and Village Association. This publication reports the activities during and the information resulting from this town meeting.Published through a grant from the Alaska Humanities Forum under the auspicies of the National Endowment for the Humanities

Solar Energy Resource Potential in Alaska

Solar energy applications are receiving attention in Alaska as in much of the rest of the country. Solar energy possibilities for Alaska include domestic water heating, hot-water or hot-air collection for space heating, and the use of passive solar heating in residential or commercial buildings. As a first analysis, this study concentrated on applying solar energy to domestic hot-water heating needs (not space heating) in Alaska, and an analysis of solar hot-water heating economics was performed using the F-CHART solar energy simulation computer program. Results indicate that solar energy cannot compete economically with oil-heated domestic hot water at any of the five study locations in Alaska, but that it may be economical in comparison with electrically heated hot water if solar collector systems can be purchased and installed for $20 to$25 per square foot.This work was made possible by a grant from the Solar Planning Office, West, 3333 Quebec, Denver, Colorado. It was performed as the Alaskan response to a western regional solar energy planning grant from the U. S. Department of Energy. The authors wish to acknowledge the support and cooperation of the Alaska State Department of Commerce, Division of Energy and Power Development, through whose efforts the grant was made available, especially Clarissa Quinlan, Grant Peterson, and Don Markle

Hydrologic Properties of Subarctic Organic Soils

Completion Report for U. S. Forest Service Institute of Northern Forestry Cooperative Agreement No. 16 USC 581; 581a-581iThe need for understanding the natural system and how it responds to various stresses is important; this is especially so in an environment where the climate not only sustains permafrost, but develops massive seasonal frost as well. Consequently, the role of the shallow surface organic layer is also quite important. Since a slight change in the soil thermal regime may bring about a phase change in the water or ice, therefore, the system response to surface alterations such as burning can be quite severe. The need for a better understanding of the behavior and properties of the organic layer is, therefore, accentuated. The central theme of this study was the examination of the hydrologic and hydraulic properties of subarctic organic soils. Summarized in this paper are the results of three aspects of subarctic organic soil examinations conducted during the duration of the project. First, a field site was set up in Washington Creek with the major emphasis on measuring numerous variables of that soil system during the summer. The greatest variations in moisture content occur in the thick organic soils that exist at this site. Our major emphasis was to study the soil moisture levels in these soils. This topic is covered in the first major section, including associated laboratory studies. Those laboratory studies include investigations of several hydraulic and hydrologic properties of taiga organic and mineral soils. Second, some field data on organic moisture levels was collected at the site of prescribed burns in Washington Creek to ascertain the sustainability of fires as a function of moisture levels. This portion of the study is described under the second major heading. The last element of this study was a continued application of the two-dimensional flow model that was developed in an earlier study funded by the U. S. Forest Service, Institute of Northern Forestry, and reported by Kane, Luthin, and Taylor (1975a). Many of the results and concepts gathered in the field work were integrated into the modeling effort, which is aimed at producing better estimates of the hydrologic effects of surface disturbances in the black spruce taiga subarctic ecosystem. This knowledge should also contribute to better fire management decisions of the same system.The work upon which this report is based was made possible by a cooperative aid agreement funded by the U. S. Forest Service, Institute of Northern Forestry, Fairbanks, Alaska. Contribution to this study was also made by Ohio State University

Effects of seasonability and variability of streamflow on nearshore coastal areas: final report

General nature and scope of the study: This study examines the variability of streamflow in all gaged Alaskan rivers and streams which terminate in the ocean. Forty-one such streams have been gaged for varying periods of time by the U. S. Geological Survey, Water Resources Division. Attempts have been made to characterize streamflow statistically using standard hydrological methods. The analysis scheme which was employed is shown in the flow chart which follows. In addition to the statistical characterization, the following will be described for each stream when possible: 1. average period of break-up initiation (10-day period) 2. average period of freeze-up (10-day period) 3. miscellaneous break-up and freeze-up data. 4. relative hypsometric curve for each basin 5. observations on past ice-jam flooding 6. verbal description of annual flow variation 7. original indices developed in this study to relate streamflow variability to basin characteristics and regional climate.This study was supported under contract 03-5-022-56, Task Order #4, Research Unit #111, between the University of Alaska and NOAA, Department of Commerce to which funds were provided by the Bureau of Land Management through an interagency agreement

Der Fahrtabschnitt M78/2 vom 1. April (Port of Spain, Trinidad) bis 11. Mai 2009 (Rio de Janeiro, Brasilien) ist die letzte Ausfahrt im Rahmen des DFG-Schwerpunktprogramms SPP 1144 zu den Hauptarbeitsgebieten zwischen 5° und 11°S entlang des südlichen mittelatlantischen Rückens. Fahrtleiter ist Dr. Richard Seifert vom Institut für Biogeochemie und Meereschemie der Universität Hamburg. Die zentralen Fragestellungen des SPP 1144 sind: Wie findet der Energie- und Stofffluss vom Erdmantel in den Ozean statt? Auf welchen Zeitskalen erfolgen die Prozesse an Spreizungszonen? Die auf vorangegangenen Fahrten (M62/5, CD169, M64/1, M68/1 und Atalante 2008) entdeckten aktiven Hydrothermalfelder bieten hervorragende Voraussetzungen für die geplanten Arbeiten.
