The stratified sequence covering the acoustic basement is gently deformed and includes marine clastic and diatomaceous sediments ranging in age from middle or late Miocene through early Pleistocene. Dense argillite, siltstone, and calcareous sandstone of early Tertiary age in and near the Zhemchug Canyon probably represent an older part of this sequence. The main layered sequence accumulated above the acoustic basement in shallow water, and, because the older beds now lie as much as 1000 m below sea level, the continental margin must have undergone considerable subsidence during late Tertiary and Quaternary time. A rich pollen flora indicates that the shoreline lay only a few tens of kilometers away from the site of the Pribilof Canyon during late Miocene time.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1969)80[1471:CTAEPR]2.0.CO;2","usgsCitation":"Hopkins, D., Scholl, D.W., Addicott, W.O., Pierce, R.L., Smith, P.B., Wolfe, J.A., Gershanovich, D., Kotenev, B., Lohman, K.E., Lipps, J.H., and Obradovich, J.D., 1969, Cretaceous, Tertiary, and early Pleistocene rocks from the continental margin in the Bering Sea: Geological Society of America Bulletin, v. 80, no. 8, p. 1471-1480, https://doi.org/10.1130/0016-7606(1969)80[1471:CTAEPR]2.0.CO;2.","productDescription":"12 p.","startPage":"1471","endPage":"1480","costCenters":[],"links":[{"id":389121,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Bering Sea, Pribilof Canyon, Zhemchug Canyon","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -174.517822265625,\n              54.99022172004893\n            ],\n            [\n              -164.520263671875,\n              54.99022172004893\n            ],\n            [\n              -164.520263671875,\n              58.21123794344608\n            ],\n            [\n              -174.517822265625,\n              58.21123794344608\n            ],\n            [\n              -174.517822265625,\n              54.99022172004893\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"80","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Hopkins, David M.","contributorId":37409,"corporation":false,"usgs":true,"family":"Hopkins","given":"David M.","affiliations":[],"preferred":false,"id":823057,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Scholl, David W. 0000-0001-6500-6962 dscholl@usgs.gov","orcid":"https://orcid.org/0000-0001-6500-6962","contributorId":3738,"corporation":false,"usgs":true,"family":"Scholl","given":"David","email":"dscholl@usgs.gov","middleInitial":"W.","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":823058,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Addicott, Warren O.","contributorId":80668,"corporation":false,"usgs":true,"family":"Addicott","given":"Warren","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":823059,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pierce, Richard L.","contributorId":265588,"corporation":false,"usgs":false,"family":"Pierce","given":"Richard","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":823060,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Smith, Patsy Beckstead","contributorId":69135,"corporation":false,"usgs":true,"family":"Smith","given":"Patsy","email":"","middleInitial":"Beckstead","affiliations":[],"preferred":false,"id":823061,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Wolfe, Jack A.","contributorId":102474,"corporation":false,"usgs":true,"family":"Wolfe","given":"Jack","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":823062,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Gershanovich, David","contributorId":265589,"corporation":false,"usgs":false,"family":"Gershanovich","given":"David","email":"","affiliations":[],"preferred":false,"id":823063,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Kotenev, Boris","contributorId":265590,"corporation":false,"usgs":false,"family":"Kotenev","given":"Boris","email":"","affiliations":[],"preferred":false,"id":823064,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Lohman, Kenneth E.","contributorId":265591,"corporation":false,"usgs":false,"family":"Lohman","given":"Kenneth","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":823065,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Lipps, Jere H.","contributorId":174189,"corporation":false,"usgs":false,"family":"Lipps","given":"Jere","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":823066,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Obradovich, John D.","contributorId":84361,"corporation":false,"usgs":true,"family":"Obradovich","given":"John","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":823067,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}}

Earth heat originates from radioactive decay of U, Th and K in the crust and mantle. Although land heat-flow measurements in the Arctic are too few for regional interpretation, those from Cape Thompson, Barrow and Cape Simpson, Northern Alaska are discussed and figured to show what they contribute to understanding of permafrost, climatic change and shoreline movements. Measuring thermal conductivity and gradient is much simpler in ocean basins than on land. Locations of such measurements are mapped, the results for the Alaskan quadrant in more detail. The sharp change in heat flow at the edge of the Alpha Cordillera, shown in a geothermal model, suggests that this feature is a huge accumulation of basalt, rather than mantle material or remnant of a foundering continent as previously postulated.

Burt pointed out the ever-changing characteristics of home-range area and the consequent absence of boundaries in the usual sense--a finding verified by investigators thereafter.  In the studies summarized in this paper, sizes of home ranges of Peromyscus varied within two magnitudes, approximately from 0.1 acre to ten acres, in 34 studies conducted in a variety of habitats from the seaside dunes of Florida to the Alaskan forests.      Variation in sizes of home ranges was correlated with both environmental and physiological factors; with habitat it was conspicuous, both in the same and different regions.  Food supply also was related to size of home range, both seasonally and in relation to habitat.  Home ranges generally were smallest in winter and largest in spring, at the onset of the breeding season.  Activity and size also were affected by changes in weather.  Activity was least when temperatures were low and nights were bright.  Effects of rainfall were variable.  Sizes varied according to sex and age; young mice remained in the parents' range until they approached maturity, when they began to travel more widely. Adult males commonly had larger home ranges than females, although there were a number of exceptions. An inverse relationship between population density and size of home range was shown in several studies and probably is the usual relationship.  A basic need for activity and exploration also appeared to influence size of home range.      Behavior within the home range was discussed in terms of travel patterns, travels in relation to home sites and refuges, territory, and stability of size of home range.  Travels within the home range consisted of repeated use of well-worn trails to sites of food, shelter, and refuge, plus more random exploratory travels.  Peromyscus generally used and maintained several or many different home sites and refuges in various parts of their home ranges, and frequently shifted about so that their principal activities centered on different sets of holes at different times.      Once established, many Peromyscus remained in the same general area for a long time, perhaps for the duration of their lives.  Extent of their travels in different directions and intensity of use of different portions of their home ranges varied within a general area in response to habitat changes, loss of neighbors, or other factors.  Various authors have obtained both direct and indirect evidence of territoriality, in some degree, among certain species of Peromyscus.      Young mice dispersed from their birth sites to establish home ranges of their own. Adults also sometimes left their home areas; some re-established elsewhere; others returned after exploratory travels.  Most populations contained a certain proportion of transients; these may have been wanderers or individuals exploring out from established home ranges or seeking new ones.  When areas were depopulated by removal trapping, other Peromyscus invaded.  Invasion rates generally followed seasonal trends of reproduction and population density.      Peromyscus removed from their home areas and released elsewhere returned home from various distances, but fewer returned from greater distances than from nearby; speed of return increased with successive trials.  The consensus from present evidence is that ho-ming is made possible by a combination of random wandering and familiarity with a larger area than the day-to-day range.  Records of juvenile wanderings during the dispersal phase and of adult explorations very nearly encompassed the distances over which any substantial amount of successful homing occurred.      Methods of measuring sizes of home ranges and the limitations of these measurements were discussed in brief synopsis.

In the United States, including Alaska and Hawaii, 763 of 6,435 gages registered seiches. Nearly all the seismic seiches were recorded at teleseismic distance. This is the first time such far-distant effects have been reported from surface-water bodies in North America. The densest occurrence of seiches was in States bordering the Gulf of Mexico. The seiches were recorded on bodies of water having a wide range in depth, width, and rate of flow. In a region containing many bodies of water, seiche distribution is more dependent on geologic and seismic factors than on hydro-dynamic ones. The concept that seiches are caused by the horizontal acceleration of water by seismic surface waves has been extended in this paper to show that the distribution of seiches is related to the amplitude distribution of short-period seismic surface waves. These waves have their greatest horizontal acceleration when their periods range from 5 to 15 seconds. Similarly, the water bodies on which seiches were recorded have low-order modes whose periods of oscillation also range from 5 to 15 seconds. Several factors seem to control the distribution of seiches. The most important is variations of thickness of low-rigidity sediments. This factor caused the abundance of seiches in the Gulf Coast area and along the edge of sedimentary overlaps. Major tectonic features such as thrust faults, basins, arches, and domes seem to control seismic waves and thus affect the distribution of seiches. Lateral refraction of seismic surface waves due to variations in local phase-velocity values was responsible for increase in seiche density in certain areas. For example, the Rocky Mountains provided a wave guide along which seiches were more numerous than in areas to either side. In North America, neither direction nor distance from the epicenter had any apparent effect on the distribution of seiches. Where seismic surface waves propagated into an area with thicker sediment, the horizontal acceleration increased about in proportion to the increasing thickness of the sediment. In the Mississippi Embayment however, where the waves emerged from high rigidity crust into the sediment, the horizontal acceleration increased near the edge of the embayment but decreased in the central part and formed a shadow zone. Because both seiches and seismic intensity depend on the horizontal acceleration from surface waves, the distribution of seiches may be used to map the seismic intensity that can be expected from future local earthquakes.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"The Alaska earthquake, March 27, 1964: effects on the hydrologic regimen (Professional Paper 544)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, DC","doi":"10.3133/pp544E","usgsCitation":"McGarr, A., and Vorhis, R.C., 1968, Seismic seiches from the March 1964 Alaska earthquake: U.S. Geological Survey Professional Paper 544, Report: 43 p.; 1 Plate: 39.97 inches x 27.98 inches, https://doi.org/10.3133/pp544E.","productDescription":"Report: 43 p.; 1 Plate: 39.97 inches x 27.98 inches","additionalOnlineFiles":"Y","costCenters":[{"id":380,"text":"Menlo ParkCalif.

The changes in shoreline processes and beach morphology that were suddenly initiated by the earthquake were similar to those ordinarily caused by gradual changes in sea level operating over hundreds of years, while other more readily visible changes were similar to some of the effects of great but short-lived storms. Phenomena became available for observation within a few hours which would otherwise not have been available for many years.\n\nIn the subsided areas—including the shorelines of the Kenai Peninsula, Kodiak Island, and Cook Inlet—beaches tended to flatten in gradient and to recede shoreward. Minor beach features were altered or destroyed on submergence but began to reappear and to stabilize in their normal shapes within a few months after the earthquake. Frontal beach ridges migrated shoreward and grew higher and wider than they were before. Along narrow beaches backed by bluffs, the relatively higher sea level led to vigorous erosion of the bluff toes. Stream mouths were drowned and some were altered by seismic sea waves, but they adjusted within a few months to the new conditions.\n\nIn the uplifted areas, generally around Prince William Sound, virtually all beaches were stranded out of reach of the sea. New beaches are gradually developing to fit new sea levels, but the processes are slow, in part because the material on the lower parts of the old beaches is predominantly fine grained. Streams were lengthened in the emergent areas, and down cutting and bank erosion have increased.\n\nExcept at Homer and a few small villages, where groins, bulkheads, and cobble-filled baskets were installed, there has been little attempt to protect the postearthquake shorelines. The few structures that were built have been only partially successful because there was too little time to study the habits of the new shore features and to design appropriate protection measures. Emergence of large areas that were once below water and permanent submergence of once-useful land areas have led to many problems of land use and ownership in addition to the destruction or relocation of wildfowl, shellfish, and salmon habitats.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"The Alaska earthquake, March 27, 1964: Regional effects (Professional Paper 543)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/pp543J","usgsCitation":"Stanley, K.W., 1968, Effects of the Alaska earthquake of March 27, 1964, on shore processes and beach morphology: U.S. Geological Survey Professional Paper 543, vi, 21 p., https://doi.org/10.3133/pp543J.","productDescription":"vi, 21 p.","numberOfPages":"34","costCenters":[{"id":380,"text":"Menlo ParkCalif.

These rocks were invaded, probably in the Tertiary, by dikes and a small stock of porphyry. The ore deposits of the area are the Golden Zone breccia pipe, a nearly vertical body about in the center of the porphyry stock, and steeply dipping veins. Most veins strike north to northeast and are commonly only 1-5 feet thick, but locally are as much as 15 feet thick. Both pipe and vein deposits are gold deposits of low to moderate grade that are characterized by abundant arsenopyrite; some contain possibly economic amounts of copper, lead and zinc minerals. Of the deposits of the mine area, only the Golden Zone has been explored to any extent, and both it and some of. the veins deserve further exploration to determine their potential.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr68122","usgsCitation":"Hawley, C.C., Clark, A.L., and Benfer, J.A., 1968, Geology of the Golden Zone mine area, Alaska: U.S. Geological Survey Open-File Report 68-122, Report: 18 p.; 1 Plate: 25.60 × 20.18 inches, https://doi.org/10.3133/ofr68122.","productDescription":"Report: 18 p.; 1 Plate: 25.60 × 20.18 inches","costCenters":[],"links":[{"id":496185,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_8250.htm","linkFileType":{"id":5,"text":"html"}},{"id":42692,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1968/0122/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":42691,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1968/0122/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":147063,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1968/0122/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Golden Zone mine area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -149.667,\n              63.225\n            ],\n            [\n              -149.667,\n              63.202\n            ],\n            [\n              -149.628,\n              63.202\n            ],\n            [\n              -149.628,\n              63.225\n            ],\n            [\n              -149.667,\n              63.225\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acfe4b07f02db6801bd","contributors":{"authors":[{"text":"Hawley, C.
