Direct studies have been made in domestic fowl (<i>Gallus gallus var. domesticus</i>; Gilbert 1972), turkeys (<i>Meleagris galloparvo</i>; Bacon and Cherms 1968), and Common quail (<i>Coturnix coturnix</i>; Bacon and Koontz 1971), by feeding the birds a capsule containing dye each day, and counting dye rings in the yolks after the eggs have been hardcooked. Recently developed methods of fixing and staining eggs have revealed differences in yolk deposited during day and night, thus permitting another estimation of the number of days during which yolk was deposited, and without direct contact with the female (Grau 1976). In eggs from chickens and quail that have been fed dyes, yolk that stained darkly with dichromate was shown to be deposited during the active daytime feeding periods, while pale-staining yolk was deposited during the night. Thus, pairs of light and dark rings, which together take a day to be deposited, may be counted to estimate time of yolk formation.</p><p>In the present study we have applied the yolk ring method of estimating the number of days during which the bulk of the yolk is deposited around the central white core (Grau 1976) to the eggs of some shorebirds, gulls, terns and alcids.</p>","language":"English","publisher":"Cooper Ornithological Society","doi":"10.2307/1367636","usgsCitation":"Roudybush, T., Grau, C., Petersen, M.R., Ainley, D., Hirsch, K., Gilman, A., and Patten, S., 1979, Yolk formation in some Charadriiform birds: The Condor, v. 81, no. 3, p. 293-298, https://doi.org/10.2307/1367636.","productDescription":"6 p.","startPage":"293","endPage":"298","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":502955,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://digitalcommons.usf.edu/condor/vol81/iss3/12","text":"External Repository"},{"id":335660,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"81","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58a5770de4b057081a24eec5","contributors":{"authors":[{"text":"Roudybush, T.E.","contributorId":181760,"corporation":false,"usgs":false,"family":"Roudybush","given":"T.E.","email":"","affiliations":[],"preferred":false,"id":669477,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Grau, C.R.","contributorId":181762,"corporation":false,"usgs":false,"family":"Grau","given":"C.R.","email":"","affiliations":[],"preferred":false,"id":669478,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Petersen, Margaret R. 0000-0001-6082-3189 mrpetersen@usgs.gov","orcid":"https://orcid.org/0000-0001-6082-3189","contributorId":167729,"corporation":false,"usgs":true,"family":"Petersen","given":"Margaret","email":"mrpetersen@usgs.gov","middleInitial":"R.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":669479,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ainley, D.

During the first 5 min the kittiwake managed to become airborne a number of times but the jaeger maintained its hold and forced it back to the water. After 5 min the jaeger began to submerge the kittiwake's head, still holding it by the neck. Because of the kittiwake's struggling, the jaeger was unable to hold it under for more than 5 sec at a time. For the next 15 min it continued to submerge the victim's head, lift it out of the water, and then submerge it again. When it held the kittiwake under water, it kept both feet on its lower neck; this may have helped keep the head submerged. In the last 5 min of this activity, when the kittiwake offered little resistance, the jaeger occasionally used only its feet to push it under water.

Pairs arrived on breeding ponds as soon as sufficient meltwater was available to allow their take-off and landing. Loons apparently do not initiate nests immediately after their arrival, even when nest-sites are available. Delayed egg-laying may be dependent on a period of yolk formation. Delaying yolk formation until after arrival on nest ponds is an adaptation by loons to the variable time suitable habitat becomes available for nesting. Predation of eggs by Glaucous Gulls, Long-tailed and Parasitic jaegers and foxes varied in relation to the location of the nest-site, and the availability of alternate prey. Hatching success was the lowest recorded for Arctic Loons (5%) in 1974, when eggs of both loons and Cackling Geese were taken in large numbers by predators. Hatching success increased to 32% in 1975 when an abundance of tundra voles was observed. No loon eggs hatched after the hatching of the Cackling Goose eggs when this alternate prey was no longer available.

Despite this wide breeding distribution, the reported nesting habitat is generally restricted to steep, rocky islands and continental headlands (see Dement’ev and Gladkov 1951, Kozlova 1957, Gabrielson and Lincoln 1959, Portenko 1973, Sealy 1973, and Sowls et al. 1978). Nests are typically excavated in steep slopes and/or on vegetated plateaus, well above normal tidal influence but occasionally within the spray or storm-wash zone. Nowhere has <i>L. cirrhata</i> or any other puffin species been reported to nest in a flat, estuarine habitat in substrate normally affected by tides during the breeding season. Portenko (1973: 137) refers to Tufted Puffins breeding on Alyumka Island in the Anadyr \"estuary\" (64°40'N, 177°37'E), but Alyumka Island is a rocky coastal island having immediate offshore waters between 3-18 m deep (A.A. Kistchinski, The Ringing Center, Moscow, and George Tyner, U.S. Defense Mapping Agency, pers. comm.).</p><p>During the summers of 1976, 1977, and 1978, we found 14-18 pairs of Tufted Puffins nesting on 4 narrow sand islands (5-7 ha each) along the northcentral Alaska Peninsula at Nelson Lagoon (56°00'N, 161°10'W). As of June 1979, 25 active burrows had been reported there (Margaret R. Petersen, pers. comm.). The islands lie approximately 1.3 km from the Bering Sea coast and are protected from the sea by a long, narrow (0.5 kin) sand peninsula. The main deepwater channel in the lagoon, 3-7 m deep and 100-300 m wide at mean low water (MLW), separates the islands from the peninsula. The islands, which are free of permafrost, have a uniformly low profile with the highest elevation 1-2 m above mean high water (MHW) (Fig. 1). Each island is circumscribed by a gently sloping (&lt;5°), narrow (5-15 m) sand/gravel beach that graduates at MLW to intertidal mud- and sandflats. These are extensive on the south and southeast sides (several hundred m) and relatively narrow (10-20 m) on the north and northwest or channel sides. The banks of each island are moderate to near vertical in slope. Puffin burrows face the channel, are located at or near the vegetation/beach interface, and extend into the bank horizontally or slightly downward. Beach rye (<i>Elymus arenarius mollis</i>) grows over most of each island and is used as nesting cover by several hundred Glaucous-winged Gulls (<i>Larus glaucescens</i>) and lesser numbers of Common Eiders (<i>Somateria mollissima v-nigra</i>). Predation by gulls on puffin eggs or chicks was not observed, nor did we see gulls rob food from adult puffins returning to their burrows from foraging in the Bering Sea (cf. Nettleship 1972). Puffins were never observed feeding in the lagoon.</p>","language":"English","publisher":"American Ornithological Society","usgsCitation":"Gill, R., and Sanger, G.A., 1979, Tufted Puffins nesting in estuarine habitat: The Auk, v. 96, no. 4, p. 792-794.","productDescription":"3 p.","startPage":"792","endPage":"794","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337556,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337555,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://americanornithologypubs.org/page/access","text":"Publisher's Website"}],"country":"United States","state":"Alaska","otherGeospatial":"Nelson Lagoon","volume":"96","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c90130e4b0849ce97abd71","contributors":{"authors":[{"text":"Gill, Robert E.

Twenty species were recorded, eight of them breeding on the study area. Temporal patterns of relative abundance were obtained from aerial and ground censuses. Prominent events in the seasonal southward movements were (a) congregation of non- and post-breeding birds after mid-June, (b) an early migratory peak before early August dominated by Western Sandpipers, Short-billed Dowitchers, Least Sandpipers, and Whimbrels, and (c) a later, much larger peak in late Setember and early October dominated by Dunlins, Rock Sandpipers, Bar-tailed Godwits, and Long-billed Dowitchers. In the five-month period July- November, several hundred thousand shorebirds used the study area as a stopover and/or staging area. The most abundant species was the Dunlin. The area is also critical for such species as the Bar-tailed Godwit, apparently serving as a unique concentration site for this species prior to fall migration.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Shorebirds in Marine Environments (Studies in Avian Biology no. 2)","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Cooper Ornithological Society","usgsCitation":"Gill, R., and Jorgensen, P.D., 1979, A preliminary assessment of the timing and migration of shorebirds along the northcentral Alaska Peninsula, chap. <i>of</i> Shorebirds in Marine Environments (Studies in Avian Biology no. 2): Studies in Avian Biology, v. 2, p. 113-123.","productDescription":"9 p.","startPage":"113","endPage":"123","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337543,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337542,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.americanornithology.org/content/studies-avian-biology","text":"<I>Studies in Avian Biology</i> Homepage"}],"country":"United States","state":"Alaska","otherGeospatial":"Alaska Peninsula, Nelson Lagoon","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -161.69952392578125,\n              55.658996099428364\n            ],\n            [\n              -160.0762939453125,\n              55.658996099428364\n            ],\n            [\n              -160.0762939453125,\n              56.160847254089816\n            ],\n            [\n              -161.69952392578125,\n              56.160847254089816\n            ],\n            [\n              -161.69952392578125,\n              55.658996099428364\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c90130e4b0849ce97abd73","contributors":{"editors":[{"text":"Pitelka, Frank A.","contributorId":58508,"corporation":false,"usgs":true,"family":"Pitelka","given":"Frank","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":684307,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Gill, Robert E.

Intrusive rocks associated with the mineral deposit form two composite epizonal to hypabyssal stocks and many dikes in country rocks. The stocks are characterized by a variety of textural rock types varying from equigranular or weakly seriate biotite granite to porphyries with aphanitic or very fine grained and aplitic groundmasses. These rocks contain about equal amounts of quartz, albitic plagioclase, and microperthitic microcline and less than 2.5% biotite. Unaltered rocks contain between 0.2 and 1% CaO, less than 1.7% combined Fe</span><sub>2</sub><span>O</span><sub>3</sub><span>, FeO, and MgO, and 74.4 to 77.7% SiO</span><sub>2</sub><span>. Total alkalis are between 8 and 9%, and K</span><sub>2</sub><span>O/Na</span><sub>2</sub><span>O is about 1.1. The range of major-oxide variation is small, but it is systematically related to lithology. Many trace-elements, including B, Pb, Sn, and Li have low concentrations. Intrusive rocks associated with the Quartz Hill deposit are more albitic and possibly trace-element depleted compared to some other rocks associated with porphyry molybdenum deposits.All observed metallization and alteration is within the Quartz Hill stock. Molybdenite forms fracture coatings and occurs in veins with quartz. Alteration is widespread and includes development of secondary quartz, pyrite, K-feldspar, biotite, white mica, chlorite, and zeolite. Field relations indicate that the stocks were emplaced after regional uplift and erosion of the Coast Range batholithic complex, and K–Ar data show that intrusion and alteration took place in late Oligocene time, about 27 to 30 Ma ago. Data from the Ketchikan quadrangle indicate that porphyry molybdenum metallization in the Coast Range batholithic complex is associated with regionally extensive but spotty, middle Tertiary or younger, felsic magmatism.</span></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/e79-165","issn":"00084077","usgsCitation":"Hudson, T., Smith, J., and Elliott, R.L., 1979, Petrology, composition, and age of intrusive rocks associated with the Quartz Hill molybdenite deposit, southeastern Alaska: Canadian Journal of Earth Sciences, v. 16, no. 9, p. 1805-1822, https://doi.org/10.1139/e79-165.","productDescription":"18 p.","startPage":"1805","endPage":"1822","costCenters":[],"links":[{"id":222248,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -134.98399926363345,\n              56.25002201433318\n            ],\n            [\n              -134.98399926363345,\n              54.61996337638038\n            ],\n            [\n              -129.86277390708392,\n              54.61996337638038\n            ],\n            [\n              -129.86277390708392,\n              56.25002201433318\n            ],\n            [\n              -134.98399926363345,\n              56.25002201433318\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"16","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7858e4b0c8380cd78698","contributors":{"authors":[{"text":"Hudson, T.","contributorId":33446,"corporation":false,"usgs":true,"family":"Hudson","given":"T.","affiliations":[],"preferred":false,"id":363139,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, James G.","contributorId":44534,"corporation":false,"usgs":true,"family":"Smith","given":"James G.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":false,"id":363140,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Elliott, Raymond L.","contributorId":82667,"corporation":false,"usgs":true,"family":"Elliott","given":"Raymond","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":363141,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These large erosional bedforms and associated current ripples are found in areas where sediment grain size is 0.063-0.044 mm (4-4.5 ??), speeds of bottom currents are greatest (20-30 cm/s mean speeds under nonstorm conditions, 70 cm/s during typical storms), circulation of water is constricted by major topographic shoals (kilometers in scale), and small-scale topographic disruptions, such as ice gouges, occur locally on slopes of shoals. These local obstructions on shoals appear to disrupt currents, causing separation of flow and generating eddies that produce large-scale scour. Offshore artificial structures also may disrupt bottom currents in these same areas and have the potential to generate turbulence and induce extensive scour in the area of disrupted flow. The size and character of natural scour depressions in areas of ice gouging suggest that large-scale regions of scour may develop from enlargement of local scour sites around pilings, platforms, or pipelines. Consequently, loss of substrate support for pipelines and gravity structures is possible during frequent autumn storms. ?? 1979 Springer-Verlag New York Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF02423277","issn":"09430105","usgsCitation":"Larsen, M.C., Nelson, H., and Thor, D., 1979, Geologic implications and potential hazards of scour depressions on bering shelf, Alaska: Environmental Geology, v. 3, no. 1, p. 39-47, https://doi.org/10.1007/BF02423277.","startPage":"39","endPage":"47","numberOfPages":"9","costCenters":[],"links":[{"id":205268,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF02423277"},{"id":222598,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a197fe4b0c8380cd559f2","contributors":{"authors":[{"text":"Larsen, M.

This kind of evidence can be used to improve estimates of when earthquakes will recur on faults known to be seismically active and to identify active faults that have no record of movement during recent history.</p>\n<p>The approach is not new. Robert Page of the U.S Geological Survey described the effects of the 1958 earthquake on trees along the Fairweather fault in Alaska. He showed that tree rings methods could have been used to identify and to closely date this event. We undertook a similar study of the northern part of the San Andreas fault, in part because there are no historic records prior to 1906 along this segment.</p>\n<p>Earthquakes and surface rupture along faults affect trees in several different ways. Direct effects include fracturing, twisting, and tilting of trees that grown on the surface of the break.

Preliminary study of an assemblage obtained from the lower half of the formation revealed six to eight forms apparently identical to specimens previously known from the Tournaisian of southern France and northwestern Turkey, including four genera not previously described from North America. Sparse, poorly preserved conodonts in the same sample are of Late Devonian age. We conclude that certain radiolarian species, hitherto known only from the early Carboniferous, span the Devonian-Carboniferous boundary. The radiolarian assemblage of the Ford Lake Shale sample contrasts markedly with Late Devonian assemblages known from the Canol Shale of northern Canada and the Huron Member of the Ohio Shale; the Ford Lake Shale fauna may reflect greater oceanic influences than these other localities, which lie farther inland from the Devonian continental margin.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Holdsworth, B.K., Jones, D.L., and Allison, C., 1978, Upper Devonian radiolarians separated from chert of the Ford Lake Shale, Alaska: Journal of Research of the U.S. Geological Survey, v. 6, no. 6, p. 775-788.","productDescription":"14 p.","startPage":"775","endPage":"788","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":315070,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":315069,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1978/vol6issue6/report.pdf","text":"Report","size":"26.93 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Alaska","otherGeospatial":"Ford Lake Shale, Kandik Basin, Yukon River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -141.5,\n              64.75\n            ],\n            [\n              -141.5,\n              65\n            ],\n            [\n              -141,\n              65\n            ],\n            [\n              -141,\n              64.75\n            ],\n            [\n              -141.5,\n              64.75\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"6","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"56ac9b89e4b0403299f53b82","contributors":{"authors":[{"text":"Holdsworth, Brian K.","contributorId":75571,"corporation":false,"usgs":true,"family":"Holdsworth","given":"Brian","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":590297,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jones, D.
