These factors lend special significance to ground water as a water-supply source, even though perennially frozen ground (permafrost) profoundly modifies ground-water flow systems in much of Alaska north of the maritime southern coast and southeastern panhandle areas. Frozen ground is a virtually impermeable layer that restricts recharge, discharge, and movement of ground water, acts as a confining layer and limits the volume of unconsolidated deposits and bedrock in which water may be stored.</p>\n<p>Ground water is an untested resource in most of Alaska, but in many areas potential development of ground water far exceeds current use. Alluvium of major river valleys, such as the Yukon, Tanana, Kuskokwim and Susitna Rivers, probably contains the most extensive aquifers in the State. Large amounts of ground water are also stored in glacial outwash aquifers that underlie coastal basins and valleys, such as those at Kenai and Anchorage in the Cook Inlet lowland. Individual wells yielding more than 1,000 gallons per minute have been developed in the Tanana River valley, Cook Inlet lowland, and the coastal valleys at Seward and Juneau. Comparable yields should be possible in other areas that have similar geohydrologic environments. No major aquifers have been identified in glacial and glaciolacustrine deposits of interior valleys or in deltaic deposits. Major bedrock aquifers have been identified only in carbonate rocks of the Brooks Range and on the north side of the Alaska Range. Springs issuing from the carbonate rocks of the Brooks Range have discharges as great as 16,000 gallons per minute.</p>\n<p>Most ground-water recharge occurs beneath reaches of stream channels that are losing flow to the ground-water system. Most ground-water discharge also takes place along reaches of stream channels. This discharge augments streamflows during summer and maintains low flows during winter when there is no surface-water runoff. On the basis of a streamflow hydrograph separation technique and using the 60 percent flow-duration value as an indicator of ground-water discharge, it is estimated that 25 percent of the total volume of streamflow in Alaska (exclusive of coastal, maritime environments) is contributed by ground-water discharge.</p>\n<p>The thawing of frozen ground in the permafrost regions of Alaska causes construction and engineering problems. Disturbance of the ground surface disrupts the natural thermal equilibrium and tends to thaw part of the permafrost. Thawing can cause loss of strength, a decrease in volume, and an increase in erosion potential, particularly if the frozen ground is fine grained and poorly drained.</p>\n<p>Present deficiencies in the ground-water information base are obvious limiting factors to ground-water development in Alaska. There is a need to extend the ground-water data-collection network and to pursue special research into the quantitative aspects of ground-water hydrology in cold regions, particularly the continuous permafrost zone.</p>","language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/pp813P","usgsCitation":"Zenone, C., and Anderson, G.S.,

They are listed by the quadrangles (scale 1:250,000) into which Alaska has been subdivided for topographic mapping (p. 3). As these three agencies also issued reports and maps on other subjects, the following lists are selected in the sense that such documents are not included. Most of the listed reports and maps bear a 1977 imprint date; a few with earlier imprint dates actually were not delivered until 1977.</p><p>Reports that deal with regional tectonic hypotheses, regional syntheses, Alaska as a whole, or with areas that can not be identified with a specific quadrangle are listed under Alaska - General, as are statistical presentations, indexes, and the like. Reports and maps that deal with offshore areas not within quadrangle boundaries are listed under Offshore Areas. The Alaska - General and Offshore Areas lists appear before the alphabetically arranged quadrangle listings.</p><p>This index is intended to bring up to date the other indexes of this series, which are listed on p. 2.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr78283","usgsCitation":"Cobb, E.H., 1978, Selected Geological Survey, U.S. Bureau of Mines, and

These sea bed micro-features are regionally widespread but are not uniformly distributed. Furthermore, the microrelief, texture, and lithologic structure of sea bed sediments have been significantly modified by the disruptive processes associated with ice gouge formation. \r\n\r\nAn analysis of some 10,.200 individual gouges shows that the density of ice gouges increases with increasing latitude, increasing slope gradients, and decreasing water depth. Across the northern half of the shelf few trackline segments are free of ice gouges; in the southern portion numerous segments contain no ice gouges. However, ice gouges extend at least as far south as Cape Prince of Wales Shoal. Densities of over 200 gouges per km of trackline are not uncommon in water depths less than 30 m ,but no values higher than 50 km are encountered in water deeper than 50 m. No ice gouges have been observed in water depths exceeding 58 m. Saturation ice gouge densities (greater than 300/Pan) occur along the eastern side 6f Barrow Sea Valley and the northeast flank of Hanna Shoal. \r\n\r\nMaximum gouge incision depths per km of trackline are greatest in water 36 to 50 m deep . A maximum incision depth of 4.5 m occurs in the 35-40 m water depth interval. Individual ice gouge events wider than 100 m, most produced by multi-keeled ice fragments, are found between 31 and 45 m depths. The dominant azimuth of gouge furrows shows no preferred orientation on the Chukchi Sea shelf; only locally does bathmetric control of the trend of gouges appear. \r\n\r\nThe occurrence of current-produced bedforms within individual ice gouges suggests an interaction between slow-moving grounded or gouging ice keels and swift currents. In other cases, current-produced bedforms, interpreted as being in equilibrium with existing flow regimes, lie adjacent to ice gouges, suggesting contemporary ice gouging to water depths of at least 43 m.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr78693","usgsCitation":"Toimil, L.J., 1978, Ice-gouged microrelief on the floor of the eastern Chukchi Sea, Alaska: a reconnaissance survey: U.S. Geological Survey Open-File Report 78-693, 44, [68] leaves :ill., maps ;28 cm.; (113 p. - PGS), https://doi.org/10.3133/ofr78693.","productDescription":"44, [68] leaves :ill., maps ;28 cm.; (113 p. - PGS)","costCenters":[],"links":[{"id":144818,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1978/0693/report-thumb.jpg"},{"id":39316,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1978/0693/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ae4b07f02db5fb725","contributors":{"authors":[{"text":"Toimil, Lawrence J.","contributorId":53806,"corporation":false,"usgs":true,"family":"Toimil","given":"Lawrence","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":163160,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The two modes occur at 54 ? 4 and 37 ? 3 weight per cent chromic oxide corresponding to chromite designated as high-chromium and high-aluminum chromite respectively. The high-chromium chromite occurs exclusively with highly magnesian olivine (Fo92-97) and some interstitial diopside. The high-aluminum chromite is associated with more ferrous olivine (Fo88-92), diopside, enstatite, and feldspar.\r\n\r\nThe plot of the mole ratios Cr/(Cr+Al+Fe3+) vs. Mg/(Mg+Fe2+) usually presented for alpine chromite is shown to have a high-chromium, high-iron to low-chromium, low-iron trend contrary to that shown by stratiform chromite. This trend is characteristic of alpine type chromite and is termed the alpine trend. However, a trend similar to that for startiform chromite is discernable on the graph for the high-chromium chromite data. This latter trend is well-developed at Red Mountain, Seldovia, Alaska.\r\n\r\nAnalysis of the iron-magnesium distribution coefficient, Kd=(Fe/Mg)ol/(Fe/Mg)ch, between olivine and chromite shows that Kd for the high-chromium chromite from all ultramafic complexes has essentially the same constant value of .05 while the distribution coefficient for the high-aluminum chromite varies with composition of the chromite. These distribution coefficients are also characteristic of alpine-type chromites. The constant value for Kd for the high-chromium chromite and associated high-magnesium olivine in all alpine complexes suggests that they all crystallized under similar physico-chemical conditions.\r\n\r\nThe two types of massive chromite and their associations of silicate minerals suggest the possibility of two populations with different origins. Recrystallization textures associated with the high-aluminum chromite together with field relationships between the gabbro and the chromite pods, suggest that the high-aluminum chromite was formed by metamorphic recrystallization of the ultramafic rocks and adjacent gabbro.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr78119","usgsCitation":"Bird, M.L., 1978, Electron-microprobe study of chromitites associated with alpine ultramafic complexes and some genetic implications: U.S. Geological Survey Open-File Report 78-119, vi, 39 leaves, 15 leaves of ill. :ill. ;27 cm.; (61 p. - PGS), https://doi.org/10.3133/ofr78119.","productDescription":"vi, 39 leaves, 15 leaves of ill. :ill. ;27 cm.; (61 p. - PGS)","costCenters":[],"links":[{"id":140064,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1978/0119/report-thumb.jpg"},{"id":35451,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1978/0119/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a18e4b07f02db6052c1","contributors":{"authors":[{"text":"Bird, M.

The U. S. Geological Survey has begun a detailed evaluation of geologic environmental conditions in continental shelf regions in order to facilitate safe development of continental shelf resources. Investigations of geohazards in the northeastern Gulf of Alaska (Fig. 1) began in 1974 when 6500 km of high and medium resolution seismic reflection data were collected from the eastern gulf between Yakutat and Montague Island (Carlson, Bruns and Molnia, 1975; Von Huene and others, 1975). The first extensive sediment sampling program was begun in 1975 when approximately 400 samples of continental shelf sediments were collected from the same area of the gulf (Carlson and others, 1977b). A limited number of geotechnical measurements were made from these samples and samples collected by subsequent programs, however, systematic measurement of geotechnical properties was not started until the 1977 cruise of the NOAA ship DISCOVERER. Once unstable environments or \"geohazards\", such as slumps and slides, are delineated, geotechnical testing is an important means of quantifying such geologic processes and consequently furthering our understanding of them.</p><p>The purposes of this report are two-fold: (1) to report variations of physical properties in 1-2 meter gravity cores and (2) to recognize any variations in the areal distribution of these properties within and adjacent to an area of mass movement in the northeastern Gulf of Alaska.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr781071","usgsCitation":"Carlson, P.R., Levy, W.P., Molnia, B.F., and Hampson, J.C., 1978, Geotechnical properties of sediments from the Continental Shelf south of Icy Bay, northeastern Gulf of Alaska: U.S. Geological Survey Open-File Report 78-1071, 29 p., https://doi.org/10.3133/ofr781071.","productDescription":"29 p.","costCenters":[],"links":[{"id":419318,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1978/1071/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":161005,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1978/1071/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Icy Bay, northeastern Gulf of Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -141.74386722970848,\n              60.27643600738864\n            ],\n            [\n              -141.74386722970848,\n              59.78959667023767\n            ],\n            [\n              -141.0247576005145,\n              59.78959667023767\n            ],\n            [\n              -141.0247576005145,\n              60.27643600738864\n            ],\n            [\n              -141.74386722970848,\n              60.27643600738864\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac7e4b07f02db67b0a9","contributors":{"authors":[{"text":"Carlson, Paul R.","contributorId":81469,"corporation":false,"usgs":true,"family":"Carlson","given":"Paul","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":204000,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Levy, William P.","contributorId":102910,"corporation":false,"usgs":true,"family":"Levy","given":"William","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":203999,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Molnia, Bruce F. 0000-0001-8102-6269","orcid":"https://orcid.org/0000-0001-8102-6269","contributorId":301013,"corporation":false,"usgs":true,"family":"Molnia","given":"Bruce","email":"","middleInitial":"F.","affiliations":[{"id":36171,"text":"National Civil Applications Center","active":true,"usgs":true}],"preferred":true,"id":203997,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hampson, John C.
