The time of ‘docking’ of the terranes against cratonic Alaska is critical to defining their amalgamated size and extent during their northward motion as well as their role in the evolution of the Bering Sea. One of the largest of the tectonostratigraphic terranes, the Peninsular terrane of south central and southwestern Alaska, extends offshore along the outer Bering Sea continental margin (Beringia). Paleomagnetic data suggest that this terrane has moved northward through all of Cenozoic time, but geologic data imply that the terrane had accreted to Alaska by the end of the Mesozoic. In early Cenozoic time the eastern part of the Aleutian arc appears to have been superimposed on the Peninsular terrane, and postulated northward Cenozoic motion of the terrane would therefore have required northward motion of the arc. Two accretion models, based on docking times for terranes in Alaska, are proposed, and they illustrate that large areas of the abyssal Bering Sea, the Alaska Peninsula, the Aleutian arc, and the Beringian continental margin may be part of a superterrane or microplate called Aleutia (microplate as defined by Beck et al. (1980), i.e., a microplate is a displaced segment of lithosphere that has crustal roots, whereas a superterrane is an amalgamation of terranes which may or may not be rootless). Model A implies that the Aleutian arc developed in situ on the southern edge of Aleutia after the microplate had docked. In model B, the final docking time of the Peninsular terrane is late Cenozoic, which implies that the Aleutia microplate encompasses a mammoth area that includes parts of southern Alaska, the Alaska Peninsula, the southern Beringian margin, the abyssal Bering Sea (Kula plate), and the Aleutian arc. If model A is correct, the docking time of the Peninsular terrane is late Mesozoic or earliest Tertiary. The Aleutia microplate in this model is made up solely of the abyssal Bering Sea (Kula plate), which presumably docked at the same time or slightly after the Peninsular terrane accreted against Alaska. If model B is correct, that is, if the Aleutia collided with nuclear Alaska during the Cenozoic, then a late Cenozoic suture zone, the vestige of a large open sea that must have closed between Aleutia and Alaska, must exist in south central and southwest Alaska. Either evidence for Cenozoic closure and suturing has been obliterated in Alaska or the inferences of Cenozoic terrane motion derived from paleomagnetic data are suspect.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB088iB04p03439","usgsCitation":"Marlow, M.S., and Cooper, A.K., 1983, Wandering terranes in southern Alaska: The Aleutia Microplate and implications for the Bering Sea: Journal of Geophysical Research B: Solid Earth, v. 88, no.

It is not uncommon for a bander to have a marked bird remain in the vicinity of its banding site throughout a season and then to recapture or sight the bird there during the following season, or occasionally for several successive seasons. However, these \"special\" birds are rarely encountered away from the banding site and, if they are, it is usually because they have died and the band has been reported. Rarely do we get multiple recaptures or resightings of an individual bird that allow us to compare site fidelity at the two ends of its migration route or to determine the timing of movements between these points. Here we describe an instance of a uniquely marked Black Turnstone (<i>Arenario melanocephola)</i>&nbsp;that was studied on both its breeding and wintering grounds for 5 consecutive years. We believe this represents one of the most detailed accounts of this nature for a North American bird. </p>","language":"English","publisher":"Western, Inland, and Eastern Bird Banding Associations","usgsCitation":"Gill, R., Handel, C.M., and Shelton, L.A., 1983, Memorial to a Black Turnstone: An examplar of breeding and wintering site fidelity: North American Bird Bander, v. 8, no. 3, p. 98-101.","productDescription":"4 p.","startPage":"98","endPage":"101","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337244,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337242,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.westernbirdbanding.org/publications_NABB.html","text":"Journal's Website"}],"volume":"8","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c277fae4b014cc3a3e770e","contributors":{"authors":[{"text":"Gill, Robert E.

Simply stated, a large bird can accommodate a marker that is large enough to be seen readily by an observer but still small enough not to alter behavior or impair flight (see Marion and Shamis 1977 for review). Such is not true with smaller birds, and consequently information on their migration routes and distribution is usually poorer than for larger birds. The use of colored leg bands increases the frequency of detection of small birds that have been banded; however, a large percentage of such marked birds is usually still overlooked. Only by using highly visible techniques, such as plumage dyes and bleaches in conjunction with leg bands, can one obtain significant numbers of sightings of small birds. Here we present information from sightings of large numbers of marked Dunlins (<i>Calidris alpina</i>) and Western Sandpipers (<i>C. mauri</i>) that dramatically demonstrates this. </p>","language":"English","publisher":"Western, Inland, and Eastern Bird Banding Associations","usgsCitation":"Handel, C.M., and Gill, R., 1983, Yellow birds stand out in a crowd: North American Bird Bander, v. 8, no. 1, p. 6-9.","productDescription":"4 p.","startPage":"6","endPage":"9","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337249,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337243,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.westernbirdbanding.org/publications_NABB.html","text":"Journal's Website"}],"volume":"8","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c277fae4b014cc3a3e770c","contributors":{"authors":[{"text":"Handel, Colleen M. 0000-0002-0267-7408 cmhandel@usgs.gov","orcid":"https://orcid.org/0000-0002-0267-7408","contributorId":3067,"corporation":false,"usgs":true,"family":"Handel","given":"Colleen","email":"cmhandel@usgs.gov","middleInitial":"M.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":681624,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gill, Robert E.

Three discrete periods of ash-fall at Kodiak correlate, respectively, with Plinian tephra layers designated A, CD, and FG by Curtis (1968) in the VTTS. The ash-flow sequence overlapped with but outlasted pumice fall A, terminating within 20 hours of the initial outbreak and prior to pumice fall C. Layers E and H consist mostly of vitric dust that settled during lulls, and Layer B is the feather edge of the ash flow. The fall units filled and obscured the caldera, but arcuate and radial fissures outline a 6-km<sup>2</sup><span>&nbsp;</span>depression. The Novarupta lava dome and its ejecta ring were emplaced later within the depression. At Mt. Katmai, 10 km east of the 1912 vent, a 600-m-deep caldera of similar area also collapsed at about this time, probably owing to hydraulic connection with the venting magma system; but all known ejecta are thought to have erupted at Novarupta. Mingling of three distinctive magmas during the eruption produced an abundance of banded pumice, and mechanical mixing of chilled ejecta resulted in deposits with a wide range of bulk composition. Pumice in the initial fall unit (A) is 100% rhyolite, but fall units atop the ash flow are &gt; 98% dacite; black andesitic scoria is common only in the ash flows and in near-vent air-fall tephra. Pumice counts show the first half of the ash-flow deposit to be 91–98% rhyolite, but progressive increases of dacite and andesite eventually reduced the rhyolitic component to &lt; 2%. The later, rhyolite-poor flows were hotter, less mobile, and widely produced partially welded tuff and vapor-indurated sillar.</p><p>The main ash flow was too deflated and sluggish 16 km from the vent to surmount a 25-m-high moraine in its path but was diverted around it and continued 5 km down-valley, engulfing and charring trees but not toppling all of them. Thin ash-flow veneers feather 30–40 m up the enclosing valley walls but only where a constriction in the central VTTS locally raised the flow level. In the upper VTTS, the “high sand mark” is not a veneer but a marginal bench formed in thick tuff by differential compaction. Flooding from adjacent glaciers led to phreatic explosions that ejected blocks of tuff more welded than any yet exposed. A cluster of phreatic craters dammed a lake atop the tuff, the breaching of which caused a flood that scoured the ash-flow surface in the central VTTS, transported 50-cm blocks of welded tuff &gt; 20 km to the lowermost VTTS, and deposited 1–8 m of debris there.</p><p>Rhyolitic ejecta contain only 1–2% phenocrysts but andesite and dacite have 30–45%. Quartz is present and augite absent only in the rhyolite, but all ejecta contain plagioclase, orthopyroxene, titanomagnetite, ilmenite, apatite, and pyrrhotite; rare olivine occurs in the andesite. The zoning ranges of phenocrysts in the rhyolitic and intermediate ejecta do not overlap. New chemical data show the bulk SiO<sub>2</sub><span>&nbsp;</span>range to be: rhyolite 77 ± 0.6, dacite 66-64.5, and andesite 61.5–58.5%. The dacitic and andesitic ejecta contrast in color and density, and it is not certain whether they form a compositional continuum. Analyses reported by Fenner within the 66–76% SiO<sub>2</sub><span>&nbsp;</span>range were of banded pumice and lava and of bulk tephra that mechanically fractionated and mixed during flight. Despite the gap of 10% SiO<sub>2</sub>, Fe-Ti-oxide temperatures show a continuous range from rhyolite (805–850°C) through dacite (855–955°C) to andesite (955–990°C). Thermal continuity and isotopic and trace-element data suggest that all were derived from a single magmatic system, whether or not they were physically contiguous before eruption. If the rhyolitic liquid separated from dacitic magma, extraction was so efficient that no dacitic phenocrysts were retained and no bulk compositions in the range 66–76% SiO<sub>2</sub><span>&nbsp;</span>were created; if it were a partial melt of roof rocks atop an intermediate magma body, then such rocks had no O- or Sr-isotopic contrast with the andesite-dacite magma and clearly did not include the Jurassic arkosic or granitic basement. The presence of Holocene domes of pre-1912 glassy dacite adjacent to the 1912 vent suggest that the 7 km<sup>3</sup><span>&nbsp;</span>(or more) of high-silica rhyolitic magma (a composition rare in the Aleutian arc) was generated in less than a few thousand years. The 1912 vent is semi-encircled by several andesitic stratocones and is as close to Mageik, Trident, and Griggs volcanoes as it is to Mt. Katmai. The erupted magma probably occupied only shallow levels of an extensive system of injection and storage under a cluster of several stratovolcanoes. Although Quaternary basalt is not known to have erupted here, the intrusion of basaltic magma probably sustains the greater-VTTS magmatic system.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0377-0273(83)90003-3","issn":"03770273","usgsCitation":"Hildreth, W., 1983, The compositionally zoned eruption of 1912 in the Valley of Ten Thousand Smokes, Katmai National Park, Alaska: Journal of Volcanology and Geothermal Research, v. 18, no. 1-4, p. 1-56, https://doi.org/10.1016/0377-0273(83)90003-3.","productDescription":"56 p.","startPage":"1","endPage":"56","numberOfPages":"56","costCenters":[],"links":[{"id":221521,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Katmai National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -156.368408203125,\n              57.66303463288711\n            ],\n            [\n              -153.25927734375,\n              57.66303463288711\n            ],\n            [\n              -153.25927734375,\n              59.33318942659219\n            ],\n            [\n              -156.368408203125,\n              59.33318942659219\n            ],\n            [\n              -156.368408203125,\n              57.66303463288711\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"18","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baa4ee4b08c986b3227c4","contributors":{"authors":[{"text":"Hildreth, W. 0000-0002-7925-4251","orcid":"https://orcid.org/0000-0002-7925-4251","contributorId":100487,"corporation":false,"usgs":true,"family":"Hildreth","given":"W.","affiliations":[],"preferred":false,"id":360971,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The wedges occur in peat that has accumulated since about 3500 yr BP and have grown episodically as the permafrost table fluctuated in response to fires, other local site conditions and perhaps regional climatic changes. Radiocarbon dates suggest one or two episodes of ice-wedge growth between about 3500 and 2000 yr BP as woody peat accumulated at the site. Subsequent wedge truncation evidently followed a fire that charred the peat. Younger peat exhibits facies changes between sedge-rich components that filled troughs over the ice wedges and woody bryophytic deposits that formed beyond the troughs. A final episode of wedge development took place within the past few hundred years. Pollen data from the site indicate that boreal forest was present throughout the past 6000 yr, but that it underwent a gradual transition from a predominantly deciduous to a spruce-dominated assemblage. This change may reflect either local site conditions or a more general climatic shift to cooler, moister summers in late Holocene time. The history of ice-wedge growth shows that wedges can form and grow to more than 1 m apparent width under mean annual temperatures that probably are close to those of the Fairbanks area today (-3.5°C) and under vegetation cover similar to that of the interior Alaskan boreal forest. The commonly held belief that ice wedges develop only below mean annual air temperatures of -6 to -8°C in the zone of continuous permafrost is invalid.</span></p>","language":"English","publisher":"INSTAAR, University of Colorado","doi":"10.2307/1550918","usgsCitation":"Hamilton, T.D., Ager, T.A., and Robinson, S., 1983, Late Holocene ice wedges near Fairbanks, Alaska, USA: Environmental setting and history of growth: Arctic and Alpine Research, v. 15, no. 2, p. 157-168, https://doi.org/10.2307/1550918.","productDescription":"12 p.","startPage":"157","endPage":"168","costCenters":[],"links":[{"id":221658,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","volume":"15","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a44e7e4b0c8380cd66eb4","contributors":{"authors":[{"text":"Hamilton, T.

These investigations have demonstrated sizeable northward displacements for rocks of late Palaeozoic, Mesozoic, and early Tertiary age in those regions, with northward motion at times culminating in collision of the allochthonous terranes against the backstop of 'nuclear' Alaska14,15. A fundamental question is which parts of Alaska underwent significantly less latitudinal translation relative to the 'stable' North American continent, thereby serving as the 'accretionary nucleus' into which the displaced 'microplates'16 were eventually incorporated17,18? Here we present new palaeomagnetic results from tuffs and associated volcaniclastic rocks of early Cretaceous age from the Yukon-Kuskokwin delta region in western Alaska. These rocks were probably overprinted during the Cretaceous long normal polarity interval, although a remagnetization event as recent as Palaeocene cannot be ruled out. This overprint direction is not appreciably discordant from the expected late Cretaceous direction for cratonal North America. The implied absence of appreciable northward displacement for this region is consistent with the general late Mesozoic-early Tertiary tectonic pattern for Alaska, based on more definitive studies: little to no poleward displacement for central Alaska, though substantially more northward drift for the 'southern Alaska terranes' (comprising Alaska Peninsula, Kodiak Island, Prince William Sound area, and Matunuska Valley) since late Cretaceous to Palaeocene time. ?? 1983 Nature Publishing Group.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Nature","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1038/305516a0","issn":"00280836","usgsCitation":"Globerman, B., Coe, R.S., Hoare, J., and Decker, J., 1983, Palaeomagnetism of lower cretaceous tuffs from Yukon-Kuskokwim delta region, western Alaska: Nature, v. 305, no. 5934, p. 516-520, https://doi.org/10.1038/305516a0.","startPage":"516","endPage":"520","numberOfPages":"5","costCenters":[],"links":[{"id":205079,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/305516a0"},{"id":221038,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"305","issue":"5934","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a73aae4b0c8380cd7719e","contributors":{"authors":[{"text":"Globerman, B.R.","contributorId":105432,"corporation":false,"usgs":true,"family":"Globerman","given":"B.R.","affiliations":[],"preferred":false,"id":360741,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Coe, R.

Many (50-80%) of these animals were observed surfacing with mud trails or lying on their sides, characteristics both associated with feeding. A migration route close to shore (within 1-2 km) was used until whales neared Egegik Bay, where they began to head west 5-8 km offshore, across northern Bristol Bay. Smaller numbers of gray whales were present throughout summer in nearshore waters and estuaries along the north side of the Alaska Peninsula. At Nelson Lagoon gray whales normally used the lagoon in spring, were absent during early summer, returned in mid-summer, and then were present until late November when they departed for the wintering grounds. Gray whales were present in the lagoon most often during periods of peak tidal flow; those that appeared to be feeding were oriented into the current. Three behaviors that appeared to be associated with feeding were observed: side-feeding from a stationary position within shallow waters of lagoon channels, diving within the lagoon and in nearshore waters, and elliptical side-feeding in the surf zone along the outer coast. Large crustaceans of the genus <i>Crangon</i> were available to and probably eaten by gray whales at Nelson Lagoon.</span></p>","language":"English","publisher":"Arctic Institute of North America","publisherLocation":"Calgary, AB","doi":"10.14430/arctic2276","usgsCitation":"Gill, R., and Hall, J.D., 1983, Use of nearshore and estuarine areas by gray whales (<i>Eschrichtius robustus</i>) in the eastern Bering Sea: Arctic, v. 36, no. 3, p. 275-281, https://doi.org/10.14430/arctic2276.","productDescription":"7 p.","startPage":"275","endPage":"281","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":480225,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.14430/arctic2276","text":"Publisher Index Page"},{"id":334784,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Bering Sea","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -167.03613281249997,\n              54.08517342088679\n            ],\n            [\n              -167.03613281249997,\n              59.80063426102869\n            ],\n            [\n              -154.3359375,\n              59.80063426102869\n            ],\n            [\n              -154.3359375,\n              54.08517342088679\n            ],\n            [\n              -167.03613281249997,\n              54.08517342088679\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"36","issue":"3","noUsgsAuthors":false,"publicationDate":"1983-01-01","publicationStatus":"PW","scienceBaseUri":"589847abe4b0efcedb7072e5","contributors":{"authors":[{"text":"Gill, Robert E.

Functional relationships are derived for obtaining the trajectory from the spatial distribution of velocity and for obtaining the velocity distribution from the trajectory. It is established that the trajectory end-points impose only an integral condition on the velocity distribution, and that no individual point on the velocity distribution can be determined if only the end-points are known. An example is given of a deduced velocity distribution that is consistent with (although not uniquely determined by) the end-points of several trajectories on the lower reach of Columbia Glacier, Alaska. It is shown that constructing a velocity distribution by assigning the average trajectory velocity to the trajectory mid-point can be subject to errors of several per cent for velocity distribution features that are typical of actual glaciers. The error in this method is determined, and closed-form expressions for the trajectory are obtained, for linear velocity distributions and for two classes of second-degree distributions. The class of functions is identified to which the velocity distribution must belong for this error to be zero.</p></div></div>","language":"English","publisher":"Cambridge University Press","doi":"10.3189/S0022143000008261","issn":"00221430","usgsCitation":"Rasmussen, L.A., 1983, Calculation of a velocity distribution from particle trajectory end-points.: Journal of Glaciology, v. 29, no. 102, p. 203-214, https://doi.org/10.3189/S0022143000008261.","productDescription":"12 p.","startPage":"203","endPage":"214","numberOfPages":"12","costCenters":[],"links":[{"id":480226,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3189/s0022143000008261","text":"Publisher Index Page"},{"id":222695,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"102","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"5059f2ffe4b0c8380cd4b537","contributors":{"authors":[{"text":"Rasmussen, Lowell A.","contributorId":36930,"corporation":false,"usgs":true,"family":"Rasmussen","given":"Lowell","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":362697,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

It has a calc-alkaline dacitic composition with abundant pyroxene, plagioclase, and FeTi oxides, and minor hornblende, biotite, apatite, and zircon. Thin, clear, bubble-wall fragments are the dominant type of glass shard. This tephra can be recognized by its glass and phenocryst compositions, as determined by X-ray fluorescence, microprobe, and instrumental neutron activation techniques. It has an age between the limits of 60,000 and 120,000 yr, set by 14C and fission-track measurements, respectively. Old Crow tephra has been recognized in the Koyukuk Basin and Fairbanks region of Alaska, and in the Old Crow Lowlands of the northern Yukon Territory, some 600 km to the east-northeast. The source vent is unknown, but these occurrences, considered in relation to the distant locations of potential Quaternary volcanic sources, demonstrate the widespread distribution of this tephra and underscore its importance as a regional stratigraphic marker. ?? 1983.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0033-5894(83)90026-1","issn":"00335894","usgsCitation":"Westgate, J., Hamilton, T.D., and Gorton, M., 1983, Old Crow tephra: A new late Pleistocene stratigraphic marker across north-central Alaska and western Yukon Territory: Quaternary Research, v. 19, no. 1, p. 38-54, https://doi.org/10.1016/0033-5894(83)90026-1.","startPage":"38","endPage":"54","numberOfPages":"17","costCenters":[],"links":[{"id":266558,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0033-5894(83)90026-1"},{"id":220966,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"19","issue":"1","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"505a6d53e4b0c8380cd7508f","contributors":{"authors":[{"text":"Westgate, J.A.","contributorId":63164,"corporation":false,"usgs":true,"family":"Westgate","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":360611,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hamilton, T.

The intrusion is 12 km wide and 27 km long, and has an exposed cumulate layering thickness of about 6000 m. The contact consists of biotite and hornblende gneiss of the granulite facies, which forms a discontinuous belt as much as 200 m wide. The outer contact of the zone is a fault, along which it is in contact with regionally metamorphosed biotite schist and amphibolite of the amphibolite facies. This fault seems to be a peripheral fault along which the intrusion was uplifted to its present level. The layering in the intrusion forms an asymmetrical funnel that is elongate northwestward and is structurally deepest at the southeast end near Mount La Perouse where the layering has inward dips of as much as 85°.</p><p class=\"chapter-para\">Although the region was probably under compression at the time the gabbro was intruded, there is evidence that the intrusion's extremely sunken form is due not to tectonism but instead to subsidence from magmatic loading at high temperatures that continued after solidification. This tectonism was probably related to the interaction between the north-moving Pacific oceanic plates and the North American continent during the Tertiary. This interaction, which involved long-term right-lateral movement with a compressional component, and possibly minor subduction, on the site of the Fairweather fault, may have controlled the mode of magmatic intrusion and possibly the production of magma at depth, but does not appear to have significantly deformed the intrusion.</p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/petrology/24.4.377","issn":"00223530","usgsCitation":"Loney, R.A., and Himmelberg, G.R., 1983, Structure and petrology of the La Perouse gabbro intrusion, Fairweather Range, southeastern Alaska: Journal of Petrology, v. 24, no. 4, p. 377-423, https://doi.org/10.1093/petrology/24.4.377.","productDescription":"47 p.","startPage":"377","endPage":"423","numberOfPages":"47","costCenters":[],"links":[{"id":221442,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9c2ae4b08c986b31d2f5","contributors":{"authors":[{"text":"Loney, R.

Analyses of texture, mineralogy, paleontology, and sedimentary structures enable definition of eight lithologic units. Mineralogic studies show that past and present sedimentation at Portage has been largely mud and sand from the Susitna River on the northwest side of Cook Inlet. Six radiocarbon dates from concentrated organic debris in the core and on the surface enable determination of sedimentation rates for four intervals and show rates to be higher and to vary more at depth than rates nearer the surface. The glacier-carved Turnagain Arm fiord has been receiving sediment for at least the past 14 000 years, as estimated by extrapolation of calculated sedimentation rates to the thickness of unconsolidated sediment drilled at Portage, which totals approximately 300 m. Presently, deposition is accomplished \"instantly\" as the result of tectonic subsidence and compaction of sediment caused by periodic earthquakes, in combination with a turbid estuarine system.</span></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/e83-071","issn":"00084077","usgsCitation":"Bartsch-Winkler, S., Ovenshine, A., and Kachadoorian, R., 1983, Holocene history of the estuarine area surrounding Portage, Alaska, as recorded in a 93 m core: Canadian Journal of Earth Sciences, v. 20, no. 5, p. 802-820, https://doi.org/10.1139/e83-071.","productDescription":"19 p.","startPage":"802","endPage":"820","costCenters":[],"links":[{"id":221282,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","city":"Portage","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -149.02228178661144,\n              60.86065317996815\n            ],\n            [\n              -149.02228178661144,\n              60.82913039884252\n            ],\n            [\n              -148.93384427530816,\n              60.82913039884252\n            ],\n            [\n              -148.93384427530816,\n              60.86065317996815\n            ],\n            [\n              -149.02228178661144,\n              60.86065317996815\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"20","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a31e9e4b0c8380cd5e33a","contributors":{"authors":[{"text":"Bartsch-Winkler, S.","contributorId":31388,"corporation":false,"usgs":true,"family":"Bartsch-Winkler","given":"S.","affiliations":[],"preferred":false,"id":360781,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ovenshine, A.T.","contributorId":80268,"corporation":false,"usgs":true,"family":"Ovenshine","given":"A.T.","affiliations":[],"preferred":false,"id":360783,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kachadoorian, R.","contributorId":43231,"corporation":false,"usgs":true,"family":"Kachadoorian","given":"R.","affiliations":[],"preferred":false,"id":360782,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Varve thickness in Skilak Lake is sensitive to annual temperature and snowfall because Skilak Glacier, the dominant source of sediment for Skilak Lake, is sensitive to these climatic parameters. Trends of varve thickness are well correlated with trends of mean annual cumulative snowfall (r = -0.902) of the southern Alaska climatological division and with trends of mean annual temperature of the southern (r = 0.831) and northern (r = 0.786) Alaska climatological divisions. Trends of varve thickness also correlate with trends of annual temperature in Seattle and North Head, Washington (r = 0.632 and 0.850, respectively). Comparisons of trends of varve thickness with trends of annual temperature in California, Oregon, and Washington suggest no widespread regional correlation. Trends of annual snowfall in the southern Alaska climatological division and trends of annual temperature in the southern and northern Alaska climatological divisions are reconstructed for the years 1700-1906 A.D. Climatic reconstructions on the basis of varve thickness in Skilak Lake utilize equations derived from the regression of series of smoothed climatological data on series of smoothed varve thickness. Reconstruction of trends of mean annual cunulative snowfall in the southern Alaska climatological division suggests that snowfall during the 1700s and 1800s was much greater than that during the early and mid-1900s. The periods 1770-1790 and 1890-1906 show marked decreases in the mean annual snowfall. Reconstructed trends of the annual temperature of the northern and southern Alaska climatological divisions suggest that annual temperatures during the 1700s and 1800s were lower than those of the early and mid-1900s. Two periods of relatively high annual temperatures coincide with the periods of low annual snowfall thus determined. ?? 1983.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0033-5894(83)90015-7","issn":"00335894","usgsCitation":"Perkins, J., and Sims, J., 1983, Correlation of Alaskan varve thickness with climatic parameters, and use in paleoclimatic reconstruction: Quaternary Research, v. 20, no. 3, p. 308-321, https://doi.org/10.1016/0033-5894(83)90015-7.","startPage":"308","endPage":"321","numberOfPages":"14","costCenters":[],"links":[{"id":266560,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0033-5894(83)90015-7"},{"id":221039,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"3","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"5059fc2ee4b0c8380cd4e175","contributors":{"authors":[{"text":"Perkins, J.A.","contributorId":49769,"corporation":false,"usgs":true,"family":"Perkins","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":360899,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sims, J.D.","contributorId":9230,"corporation":false,"usgs":false,"family":"Sims","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":360898,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Since the beginning of this century, the population has shifted from nesting in numerous small colonies associated with freshwater marshes in interior California and southern Oregon to nesting primarily in large colonies on human-created habitats along the coast. Colonies at Grays Harbor, Washington and San Francisco and San Diego bays, California account for 77% of the current Pacific Coast population (6,000 pairs), which has breeding and wintering areas separate from those of populations east of the continental divide. There also appears to be some segregation on the wintering grounds by birds from the three major colonies within the Pacific population. Age-related seasonal movements in the Pacific population are characterized by (1) a brief period of northward dispersal by newly fledged birds before migrating to the wintering grounds, (2) a residency on the wintering grounds through their second winter, (3) a return to the breeding grounds the third summer, when most birds are thought to prospect breeding sites and some may breed, and (4) attainment of adulthood the fourth summer, with subsequent annual movements between wintering and breeding grounds.</p><p>The Pacific population has increased 70% since 1960, apparently all by intrinsic growth. Over half (57%) of the fledglings reach their fourth year, and they have a subsequent annual survival rate of 89% and a mean breeding life expectancy of 8.6 yr. An average annual fledging rate of 0.64 young per pair was calculated as necessary to have provided the observed growth of the population during its recent expansion. Growth of some of the <i>individual</i> colonies, however, particularly those in Washington, could only have resulted from extensive recruitment of birds from other Pacific Coast colonies. Philopatry is low in this population, and the growth of the northern colonies involved recruitment primarily of first- time breeders but also of some older adults. Factors promoting both first-time breeders and older adults to join new and often distant colonies are discussed.</p>","language":"English","publisher":"American Ornithological Society","usgsCitation":"Gill, R., and Mewaldt, L., 1983, Pacific Coast Caspian Terns: Dynamics of an expanding population: The Auk, v. 100, no. 2, p. 369-381.","productDescription":"13 p.","startPage":"369","endPage":"381","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337561,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337560,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.jstor.org/stable/4086532 "}],"volume":"100","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c90130e4b0849ce97abd6d","contributors":{"authors":[{"text":"Gill, Robert E.

The early and late Wisconsin maxima were times of prolonged annual sea-ice cover and a short cool period of phytoplankton productivity during the ice-free season. The middle Wisconsin interstade, at least in the southern Bering Sea, had greater seasonal contrast than today, with some winter sea-ice cover, an intensified temperature minimum, and high spring productivity. Variations in clastic and reworked fossil material imply varying degrees of transport to the basin by Alaskan rivers.
