Genetic differentiation of sockeye salmon subpopulations from a geologically young Alaskan lake system
C. V. Burger, William J. Spearman, M. A. Cronin
1997, Transactions of the American Fisheries Society (126) 926-938
The Tustumena Lake drainage in southcentral Alaska is glacially turbid and geologically young (<2,000 years old). Previous field studies identified at least three subpopulations of sockeye salmon Oncorhynchus nerka at Tustumena Lake, based on the distribution and timing of spawners. The subpopulations included early‐run salmon that spawned in six...

Testing for handling bias in survival estimation for black brant
James S. Sedinger, Mark S. Lindberg, Eric A. Rexstad, Nathan Chelgren, David H. Ward
1997, Journal of Wildlife Management (61) 782-791
We used an ultrastructure approach in program SURVIV to test for, and remove, bias in survival estimates for the year following mass banding of female black brant (Branta bernicla nigricans). We used relative banding-drive size as the independent variable to control for handling effects in our ultrastructure models, which took...
Estimating age of sea otters with cementum layers in the first premolar
James L. Bodkin, Jack A. Ames, Ronald J. Jameson, Ancel M. Johnson, Gary M. Matson
1997, Journal of Wildlife Management (61) 967-973
We assessed sources of variation in the use of tooth cementum layers to determine age by comparing counts in premolar tooth sections to known ages of 20 sea otters (Enhydra lutris). Three readers examined each sample 3 times, and the 3 readings of each sample were averaged by reader to...

How Does Climate Change Influence Alaska's Vegetation?: Insights from the Fossil Record
Water Resources Division, U.S. Geological Survey
1997, Fact Sheet 071-97
Plant fossils, such as leaves, wood, cones, pollen, and seeds, provide important evidence of how Alaska's vegetation has responded to climate changes over time periods of centuries to millions of years. Long-term trends of global temperatures have been reconstructed from oxygen isotope measurements of microscopic fossils (foraminifera) in the Pacific...

During FY 1997, the USGS engaged in cooperative research projects, data collection, informal outreach, and work done under Memoranda of Understanding that related to American Indians or Alaska Natives. Some work was technical and/or research-oriented. Other work was educational....
Sea otter mortality from the Exxon Valdez spill: Evaluation of an estimate from boat-based surveys
David L. Garshelis, James A. Estes
1997, Marine Mammal Science (13) 341-351
The Exxon Valadez oil spill killed large numbers of sea otters (Enhydra lutris) in Prince William Sound (PWS), Alaska, where the spill originated, as well as within the oil’s path along the coasts of the Kenai Peninsula and Kodiak Island. Sea otters attracted particular attention after the spill due to...
A strategy for monitoring glaciers
Andrew G. Fountain, Robert M. Krimmel, Dennis C. Trabant
1997, Circular 1132
Glaciers are important features in the hydrologic cycle and affect the volume, variability, and water quality of runoff. Assessing and predicting the effect of glaciers on water resources require a monitoring program to provide basic data for this understanding. The monitoring program of the U.S. Geological Survey employs a nested...

Evaluation of conditions along the grounding line of temperate marine glaciers: An example from Muir Inlet, Glacier Bay, Alaska
K.C. Seramur, R.D. Powell, P.R. Carlson
1997, Marine Geology (140) 307-327
In the marine environment, stability of the glacier terminus and the location of subglacial streams are the dominant controls on the distribution of grounding-line deposits within morainal banks. A morainal bank complex in Muir Inlet, Glacier Bay, SE Alaska, is used to develop a model of terminus stability and location...

1997, Journal of Geophysical Research B: Solid Earth (102) 20639-20643
This special section of the Journal of Geophysical Research addresses the composition and structural evolution of the lithosphere in northern Alaska. Investigations reported in this section were mainly undertaken as part of the Trans‐Alaska Crustal Transect (TACT), an integrated geological and geophysical transect of the entire Alaskan lithosphere along...
Crustal implications of bedrock geology along the Trans-Alaska Crustal Transect (TACT) in the Brooks Range, northern Alaska
Thomas E. Moore, W. K. Wallace, C. G. Mull, K.E. Adams, George Plafker, W. J. Nokleberg
1997, Journal of Geophysical Research B: Solid Earth (102) 20645-20684
Geologic mapping of the Trans-Alaska Crustal Transect (TACT) project along the Dalton Highway in northern Alaska indicates that the Endicott Mountains allochthon and the Hammond terrane compose a combined allochthon that was thrust northward at least 90 km in the Early Cretaceous. The basal thrust of the combined allochthon climbs...
Tectonic evolution of the central Brooks Range mountain front: Evidence from the Atigun Gorge region
C. G. Mull, R.K. Glenn, K.E. Adams
1997, Journal of Geophysical Research B: Solid Earth (102) 20749-20772
Atigun Gorge, at the northern front of the eastern Endicott Mountains, contains well-exposed rocks of the upper part of the Endicott Mountains allochthon and rocks of the structurally higher Picnic Creek or Ipnavik River allochthon. These allochthons contain rocks as young as Early Cretaceous (Valanginian) and are separated by a...

Controls on accretion of flysch and melange belts at convergent margins: Evidence from the Chugach Bay thrust and Iceworm melange, Chugach accretionary wedge, Alaska
Timothy M. Kusky, Dwight Bradley, Peter J. Haeussler, Susan M. Karl
1997, Tectonics (16) 855-878
Controls on accretion of flysch and mélange terranes at convergent margins are poorly understood. Southern Alaska's Chugach terrane forms the outboard accretionary margin of the Wrangellia composite terrane, and consists of two major lithotectonic units, including Triassic-Cretaceous mélange of the McHugh Complex and Late Cretaceous flysch of the Valdez Group....
