Structural evolution of an arc-basin: The Gravina Belt in central southeastern Alaska
Peter J. Haeussler
1992, Tectonics (11) 1245-1265
The upper Middle Jurassic-Lower Cretaceous Gravina belt lies along the eastern margin of the Alexander terrane in southeastern Alaska. This group of turbidites and mafic to intermediate volcanic rocks was deformed during mid to Late Cretaceous time during the closing of a basin of unknown size between the Alexander terrane...
Antipredator strategies in breeding Bristle-thighed Curlews
Brian J. McCaffery, Robert E. Gill Jr.
1992, American Birds (46) 378-383
Each fall the world’s breeding population of Bristle-thighed Curlews (Numenius tahitiensis) arrives on the central Pacific wintering grounds following a migration that entails a non- stop flight of over 5000 kilometers. Sun-drenched, palm-shrouded atolls will be their home for the ensuing eight months. Even in the avian world, however, such...
Reproductive implications of egg-size variation in Black Brant
Paul L. Flint, James S. Sedinger
1992, The Auk (109) 896-903
We analyzed variation in egg size of Black Brant (Branta bernicla nigricans) in relation to clutch size, laying date, female age, year, and position in the laying sequence. A total of 3,478 eggs was measured over three years. Egg size increased with clutch size and female age, and decreased with...
Paleomagnetism and geochronology of 23 Ma gabbroic intrusions in the Keku Strait, Alaska, and implications for the Alexander Terrane
Peter J. Haeussler, Robert S. Coe, Paul R. Renne
1992, Journal of Geophysical Research B: Solid Earth (97) 19641-19649
Samples of Tertiary gabbro from 24 sites in the Keku Strait, Alaska, help constrain the displacement history of the Alexander terrane. Step heating experiments on a plagioclase separate from these previously undated intrusions indicate a discordant 40Ar/39Ar age of 23.1 ± 1.7 Ma. The characteristic magnetization resides in magnetite, is...
Paleomagnetism of the Late Triassic Hound Island Volcanics: Revisited
Peter J. Haeussler, Robert S. Coe, T.C. Onstott
1992, Journal of Geophysical Research B: Solid Earth (97) 19617-19639
The collision and accretion of the Alexander terrane profoundly influenced the geologic history of Alaska and western Canada; however, the terrane's displacement history is only poorly constrained by sparse paleomagnetic studies. We studied the paleomagnetism of the Hound Island Volcanics in order to evaluate the location of the Alexander terrane...
Breeding distribution of the Black Turnstone
Colleen M. Handel, Robert E. Gill Jr.
1992, The Wilson Bulletin (104) 122-135
Eighty-five percent of the world population of Black Turnstones (Arenaria melanocephala) nest on the central Yukon-Kuskokwim Delta, Alaska, 65% concentrated in a narrow band of salt grass, graminoid, and dwarf shrub meadows within two km of the...
Change-in-ratio estimators for populations with more than two subclasses
Mark S. Udevitz, Kenneth H. Pollock
1991, Biometrics (47) 1531-1546
Change-in-ratio methods have been developed to estimate the size of populations with two or three population subclasses. Most of these methods require the often unreasonable assumption of equal sampling probabilities for individuals in all subclasses. This paper presents new models based on the weaker assumption that ratios of sampling probabilities...
A comparison of aerial and boat-based surveys for marbled murrelets in southeast Alaska, July 23-28, 1991
John F. Piatt, Bruce Conant, Chris Iverson
1991, Report
Aerial and boat-based surveys for Marbled Murrelets (Brachyramphus marmoratus) were conducted simultaneously over short transect distances (ca. 2 km) in three different areas of the Alexander Archipelago to assess the accuracy and variability of aerial counts compared to boat-based counts. Additional aerial surveys were conducted over a wider geographic area...
Elevations and distances in the United States
Water Resources Division, U.S. Geological Survey
1991, Report
The information in this booklet was compiled to answer inquiries received by the U.S. Geological Survey from students; teachers; writers; editors; publishers of encyclopedias, almanacs, and other reference books; and people in many other fields of work. The elevations of features and distances between points in the United States were...
Denali Park wolf studies: Implications for Yellowstone
L. David Mech, Thomas J. Meier, John W. Burch
1991, Conference Paper, Transactions of the 56th North American Wildlife and Natural Resources Conference
The Northern Rocky Mountain Wolf Recovery Plan approved by the U.S. Fish and Wildlife Service (1987) recommends re-establishment of wolves (Canis lupus) in Yellowstone National Park. Bills proposing wolf re-establishment in the Park have been introduced into the U.S. House and Senate. However, several questions have been raised about the...
Observations at convergent margins concerning sediment subduction, subduction erosion, and the growth of continental crust
Roland E. von Huene, D.W. Scholl
1991, Reviews of Geophysics (29) 279-316
At ocean margins where two plates converge, the oceanic plate sinks or is subducted beneath an upper one topped by a layer of terrestrial crust. This crust is constructed of continental or island arc material. The subduction process either builds juvenile masses of terrestrial crust through arc volcanism or new...
