The chemocline extends in depth from 80 to 100 m (meters) and the steepest gradient is between 98 and 100 m. The monimolimnion is anoxic, contains hydrogen sulflde, and has a salinity about two-thirds that of seawater. Turnover appears to introduce additional sodium chloride from the chemocline to the mixolimnion, but diffusion is probably the dominant mixing mechanism. Vertical profiles show a dichothermic temperature curve. A minimum temperature of 3°C in the chemocline is unexplained, but higher temperatures in the monimolimnion may be a result of solar radiation. At the lower limit of the chemocline there is a sharp decrease in pH, which could be due to bacterial action. Redoubt Lake is probably a relict fiord. The data presented herein support the hypothesis that the lake was gradually isolated from the sea by uplift. While seawater was entering the lake, it probably mixed with the freshwater in the mixolimnion and therefore the monimolimnion is less saline than seawater. Geologic and geophysical evidence support the speculation that significant amounts of saltwater inflow probably ceased about 650-800 years before the present.</p>","language":"English","publisher":"U.

Radiometric age determinations on selected metamorphic rocks have helped to identify two major metamorphic events, one in Late Cretaceous time that was characterized by penetrative deformation, and one in the Miocene Epoch that resulted in widespread recrystallization and igneous intrusions. Mapped facies units show many discontinuities across major faults, and their distribution indicates major differential uplift between several structurally bound crustal blocks within a strongly deformed mobile belt west of the Art Lewis fault. Late Cretaceous metamorphic gradients indicate that the blocks have been tilted to the west or northwest parallel to their general structural grain.

Results of potassium-argon age determinations combined with field relations, petrography, and major- and trace-element chemistry suggest six major intrusive events: (1) late Paleozoic gabbro to quartz diorite intruded Paleozoic metamorphic rocks that are probably equivalent to the Kaskawulsh Group in adjacent areas of Canada, (2) Triassic quartz diorite formed one small pluton in undated metamorphic rocks near Mt. St. Elias, (3) Jurassic tonalite and granite intruded upper Paleozoic(?) and lower Mesozoic(?) metamorphic rocks, (4) Late Cretaceous or Tertiary altered tonalite formed three widely separated plutons in metasedimentary rocks of Jurassic(?) and Cretaceous age in the Yakutat Group, (5) Eocene granodiorite and granite, and (6) late Cenozoic tonalite and granodiorite intruded both the Yakutat Group and upper Paleozoic(?) and lower Mesozoic(?) metamorphic rocks. The Paleozoic, Jurassic, and Cretaceous or Tertiary plutonic suites are restricted to particular geologic terranes, and the Jurassic and Eocene suites correlate with regional plutonic belts present elsewhere in southern Alaska. The distribution of the Tertiary plutons does not require large-scale horizontal displacements along the Fairweather and other major high-angle faults. The available data indicate that the mineral resource potential of the Yakutat-St. Elias area is low for those deposits that are generally related to magmatic processes. </p>","language":"English","publisher":"U.

At both localities, pillow basalts are interbedded with flysch, and the gabbros intrude both the sheeted dikes and the immediately overlying sedimentary rocks. At the Resurrection Peninsula, small bodies of serpentinized dunite are present in the gabbro, and overlying low-grade metasedimentary rocks and mafic tuffs are interbedded with sedimentary rocks. At Knight Island the sheeted dikes intrude Paleocene and Eocene(?) sedimentary rocks. These igneous rocks have petrographic features similar to those of oceanic tholeiites and have some of the characteristics of ophiolites. They apparently were formed near the continental margin, because both sequences intrude and are interlayered with flysch.

Landslides associated with earthquakes may cause as much damage as the initial ground shaking.

THe Hebgen Lake, Mont., earthquake of 1959 triggered a very large landslide (fig. 1) that killed and injured many people, formed a temporary lake, and blocked travel in the area. The Anchorage, Alaska, earthquake of 1964 triggered extensive subaerial (fig 2.) and submarine landslides; tsunamis (seismic sea waves) generated by the submarine landslides caused extensive damage and many fatalities in coastal areas. The earthquake in western Peru in 1970 triggered a massive debris avalanche (fig. 3) that destroyed the cities of Yungay and Ranrahirca; it probably caused about one-half of the 38,000 fatalities attributed to the earthquake. The San Fernando, Calif., earthquake of February 9, 1971, triggered more than 6000 individual landslides, most of which were small (fig. 4), in the surrounding upland areas. Fortunately, only a few of them damaged manmade structures because residential and industrial development had been restricted almost wholly to the relatively flat floor of the San Fernando Valley.</p>\n<p>Each of the major earthquakes described above had magnitudes greater than 6.5. Although smaller earthquakes may cause less damage to manmade structures by ground shaking, they are capable of triggering slope failures, especially renewed movements of old, marginally stable landslide deposits (fig. 5), in hillside areas.&nbsp;</p>","language":"English","publisher":"U.S Geological Survey","usgsCitation":"Nilsen, T.H., 1977, Landslides: Earthquake Information Bulletin (USGS), v. 9, no. 2, p. 27-33.","productDescription":"7 p.","startPage":"27","endPage":"33","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":319289,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"9","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"56f3be44e4b0f59b85e02ea3","contributors":{"authors":[{"text":"Nilsen, T.

An additional 142,800 hectares (550 square miles or 352,900 acres) lying in part between the study area and the International Boundary and in part contiguous to the southwest of the study area were studied because of their importance to the evaluation of the study area itself. Unless otherwise specified, the term Study Area as used in this report includes both the formally designated study area and these contiguous areas.

Nesting begins as soon as the tundra starts to clear of snow and appears to be timed so that the young of the year reach independence before the end of adult insect emergence. Arthropod prey become abruptly scarce after the period of insect emergence and thus probability of success for late broods is low. Time of nesting is also discussed in relation to factors of predation and timing of molt. At least 42.9% of males and 45.4% of females survived the next season after 1 year of age. Maximum longevity observed for both sexes is 6 years. Mean clutch size for all years investigated was 5.06 eggs per clutch. Clutch size showed both yearly and seasonal variation. The data indicate that timing of nesting is the chief factor in the observed clutch size differences, further modified by habitat quality, second nesting attempts, and probably age of female. Over a 4-year period the longspur breeding population on a 17-ha study plot declined from 15 to 2 breeding females. Life-table analysis indicates that low fledgling success for 3 consecutive years apparently was the main cause of this decline. Overall mean egg success was 44.0%, but close to 60% in 4 years considered more \"normal.\" The low egg success was due to 3 consecutive years of high predation, which may have been related to the disrupted lemming cycle of the Barrow region.</span></p>","language":"English","publisher":"American Ornithological Society","usgsCitation":"Custer, T.W., and Pitelka, F.A., 1977, Demographic features of a lapland longspur population near Barrow, Alaska: The Auk, v. 94, no. 3, p. 505-525.","productDescription":"21 p.","startPage":"505","endPage":"525","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":133955,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":341290,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.jstor.org/stable/4085218"}],"volume":"94","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49ffe4b07f02db5f780a","contributors":{"authors":[{"text":"Custer, Thomas W. 0000-0003-3170-6519 tcuster@usgs.gov","orcid":"https://orcid.org/0000-0003-3170-6519","contributorId":2835,"corporation":false,"usgs":true,"family":"Custer","given":"Thomas","email":"tcuster@usgs.gov","middleInitial":"W.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":312783,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pitelka, Frank A.","contributorId":58508,"corporation":false,"usgs":true,"family":"Pitelka","given":"Frank","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":312782,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Its open waters, tidal flats, tidal marshes and solar evaporation ponds provide critical foraging, resting and breeding habitat for migratory and resident birds. The avifauna of San Francisco Bay has received considerable attention; however, little of it has been directed toward assessing the overall importance of the Bay as a nesting area. Works by Grinnell and Wythe (1927), Grinnell and Miller (1944) and Sibley (1952) are the only comprehensive studies of San Francisco Bay avifauna. These studies, while major contributions, are broad in scope as they relate to the breeding avifauna of the Bay's estuarine areas. Several studies by Johnston (1955, 1956a, b), Marshall (1948a, b), DeGroot (1927, 1931) and Zucca (1954) have concentrated on the breeding biology of individual species; however, much of the marsh reclamation and Bay fill has occurred since. The present breeding status of many resident and migratory birds is poorly known for San Francisco Bay. Included among these are three rare or endangered forms: California Black Rail, California Clapper Rail and California Least Tern. In addition, some species now found in the area represent recent breeding range extensions. This study, undertaken from March to September 1971 and including a few more recent data, presents a quantitative assessment of the present breeding bird populations in the South San Francisco Bay area.</p>","language":"English","publisher":"Western Field Ornithologists","usgsCitation":"Gill, R., 1977, Breeding avifauna of the south San Francisco Bay estuary: Western Birds, v. 8, no. 1, p. 1-12.","productDescription":"12 p.","startPage":"1","endPage":"12","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"links":[{"id":337144,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337143,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.westernfieldornithologists.org/archive/V08/journal-08-1.php","text":"Volume 8, Number 1 on Journal's Website"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -122.30255126953126,\n              37.355967684576406\n            ],\n            [\n              -121.90498352050781,\n              37.355967684576406\n            ],\n            [\n              -121.90498352050781,\n              37.644684587165884\n            ],\n            [\n              -122.30255126953126,\n              37.644684587165884\n            ],\n            [\n              -122.30255126953126,\n              37.355967684576406\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"8","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c12664e4b014cc3a3d353f","contributors":{"authors":[{"text":"Gill, Robert E.

The Yakataga Formation, with an aggregate outcrop thickness of about 5,000 m, is characterized by variable amounts of distinctive neritic marine tillite-like diamictite and laminated siltstone containing dropstones interpreted as ice-rafted glacial debris. The lithology, sedimentary structures and molluscan fauna of the formation suggest that active tidal glaciers or an ice shelf were present along the landward margin of the basin possibly beginning in early or early middle Miocene time. Dropstone distribution in outcrop sections indicates that glaciers reached tidewater intermittently during the Miocene and were almost continually present throughout the Pliocene and much of the Pleistocene. Paleomagnetic and nannoplankton dating of the upper 1,181 m of the Yakataga Formation at Middleton Island indicate that this part of the sequence probably was entirely deposited during the Matuyama reversed polarity epoch of the Pleistocene during which the sedimentation rate was of the order of 1 m/1,000 years. Lithologically similar deposits of poorly consolidated sandy mud and pebbly mud continue to accumulate locally near tidal glaciers in the same area, and older late Quaternary deposits are undoubtedly present offshore. The anomalous late Cenozoic glaciation recorded in the sediments along the Gulf of Alaska margin reflects a fortuitous combination of a subsiding shelf basin adjacent to an area of extremely high elevations and exceptionally heavy precipitation, an environment that persists to the present.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Recent and ancient sedimentary environments in Alaska: Proceedings of the Alaska Geological Society Symposium held April 2-4, 1975, at Anchorage, Alaska","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"Alaska Geological Society","publisherLocation":"Anchorage, AK","usgsCitation":"Plafker, G., and Addicott, W., 1976, Glaciomarine deposits of Miocene through Holocene age in the Yakataga Formation along the Gulf of Alaska margin, Alaska, <i>in</i> Recent and ancient sedimentary environments in Alaska: Proceedings of the Alaska Geological Society Symposium held April 2-4, 1975, at Anchorage, Alaska, p.

The Survey estimates that fields discovered in Alaska through 1972 ultimately may produce about 26 billion bbl of oil and 68 Tcf of natural gas. In northern Alaska, Paleozoic and Mesozoic shelf and slope carbonate and clastic rocks of the Brooks Range orogen were thrust relatively northward over the depressed south margin of the Paleozoic and Mesozoic Arctic platform. A foredeep, the Colville geosyncline, developed across the depressed margin of the platform in earliest Cretaceous time. Detritus from the Brooks Range filled the foredeep and prograded northward to fill the Cretaceous and Tertiary North Chukchi and Umiat-Camden basins and form the progradational Beaufort shelf. The largest petroleum reserves (Prudhoe Bay and associated fields) and the best prospects for additional large discoveries in Alaska lie in the areally extensive upper Paleozoic to Tertiary carbonate and clastic rocks of northern Alaska. In southern Alaska, a series of arc-trench systems developed on oceanic rocks during Jurassic and Cretaceous time. Between these arcs and the metamorphic (continental) terranes of east-central and northern Alaska, large back-arc and arc-trench gap basins received thick volcanic and detrital deposits. These deposits were extensively, and commonly intensely, deformed and disrupted by mid-Jurassic to Tertiary plutonism, Laramide oroclinal bending, wrench faulting, and arc-related compression. This deformation, coupled with low porosity (in part produced by diagenetic mobilization of labile constituents), has left these rocks with only modest, local prospects for petroleum. Laramide events compressed and consolidated (\"continentalized\") the late Mesozoic back-arc basin deposits and welded them to the older continental terranes on the north and east. Subsequent sedimentation was localized and nonmarine except in onshore and offshore coastal basins, where thick sections of mixed marine and nonmarine Tertiary sediments accumulated. The Aleutian arc and the associated Queen Charlotte transform-fault system have dominated structural and depositional patterns in southern Alaska, including many of the Tertiary coastal basins, since the early Cenozoic. The Tertiary coastal basins are areally extensive, and in some areas contain many large folds. They are known to be petroliferous in Bristol Bay and the Gulf of Alaska, and to contain major accumulations of oil and gas at Cook Inlet, but they are relatively little explored.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Circum-Pacific energy and mineral resources (AAPG Memoir 25)","largerWorkSubtype":{"id":3,"text":"Organization Series"},"language":"English","publisher":"AAPG","publisherLocation":"Tulsa, OK","usgsCitation":"Grantz, A., and Kirschner, C., 1976, Tectonic framework of petroliferous rocks in Alaska: hydrocarbons, chap. <i>of</i> Circum-Pacific energy and mineral resources (AAPG Memoir 25), p. 291-307.","productDescription":"17 p.","startPage":"291","endPage":"307","costCenters":[{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"links":[{"id":266659,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266658,"type":{"id":15,"text":"Index Page"},"url":"https://archives.datapages.com/data/specpubs/mineral1/data/a175/a175/0001/0250/0291.htm"}],"country":"United States","state":"Alaska","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 172.5,51.2 ], [ 172.5,71.4 ], [ -130.0,71.4 ], [ -130.0,51.2 ], [ 172.5,51.2 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5108fd95e4b0d965cd9f2393","contributors":{"authors":[{"text":"Grantz, Arthur agrantz@usgs.gov","contributorId":2585,"corporation":false,"usgs":true,"family":"Grantz","given":"Arthur","email":"agrantz@usgs.gov","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":472602,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kirschner, C.E.","contributorId":81107,"corporation":false,"usgs":true,"family":"Kirschner","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":472603,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

St. Matthew Island is made up of approximately 500 m of subaerial calc-alkaline volcanic rocks ranging in composition from high-alumina basalt to rhyolite. Four K-Ar analyses of samples from this volcanic sequence give Late Cretaceous ages of 65-77 m.y., and intercalated carbonaceous tuff layers yield Cretaceous pollen assemblages. Along the northeast coast of St. Matthew Island, the volcanic rocks are intruded by granodiorite that gives an early Tertiary K-Ar age of 61 m.y. Correlations with on-land geology in northeast Siberia and marine geophysical data from the western Bering Sea strongly suggest that St. Matthew Island represents a southeastward extension of the Okhotsk-Chukotsk belt, a Cretaceous and early Tertiary volcanic arc that borders the Pacific margin of Siberia for nearly 3,000 km. The apparent continuation of this volcanic arc along the margin of the Bering shelf at least as far east as St. Matthew Island supports suggestions by Burk and by Scholl and others that in late Mesozoic time the Pacific plate margin coincided with the present Bering shelf margin and did not shift to the Aleutian trench until the end of Cretaceous or the beginning of Tertiary
