T. S. Smith, Steven T. Partridge, Steven C. Amstrup, S. Schliebe
2007, Arctic (60) 187-194
We observed polar bear (Ursus maritimus) maternity den sites on Alaska’s North Slope in March 2002 and 2003 in an effort to describe bears’ post-den emergence behavior. During 40 sessions spanning 459 h, we observed 8 adults and 14 dependent cubs outside dens for 37.5 h (8.2% of total observation...

The atlantic salmon: Genetics, conservation and management
Eric Verspoor, Lee Stradmeyer, Jennifer L. Nielsen, editor(s)
2007, Book
Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a...

Seabirds as indicators of marine ecosystems: Introduction: A modern role for seabirds as indicators
John F. Piatt, William J. Sydeman, Francis Wiese
2007, Marine Ecology Progress Series (352) 199-204
A key requirement for implementing ecosystem-based management is to obtain timely information on significant fluctuations in the ecosystem (Botsford et al. 1997). However, obtaining all necessary information about physical and biological changes at appropriate temporal and spatial scales is a daunting task. Intuitively, one might assume that physical data are more...
Alaskan birds at risk: Widespread beak deformities in resident species
Caroline R. Van Hemert
2007, Birding (39) 48-55
The team creeps silently across a well-tended lawn, eyes drawn to a small wooden box perched several meters up a lone birch tree. The first biologist is armed with a broom in one hand and a bug net in the other. Her partner wields a lunchbox-sized plastic case and a...
Retrospective analysis of AYK Chinook salmon growth
Gregory T. Ruggerone, Jennifer L. Nielsen, B.A. Agler
2007, Report
Harvests of Yukon and Kuskokwim Chinook salmon declined significantly during 1998- 2002 in response to fewer returning salmon. Factors affecting the decline in Chinook salmon abundance are largely unknown. Growth of salmon in freshwater and the ocean is generally thought to influence salmon survival, therefore we examined historical Chinook salmon...
Winter movement dynamics of black brant
Mark S. Lindberg, David H. Ward, T. Lee Tibbitts, John Roser
2007, Journal of Wildlife Management (71) 534-540
Although North American geese are managed based on their breeding distributions, the dynamics of those breeding populations may be affected by events that occur during the winter. Birth rates of capital breeding geese may be influenced by wintering conditions, mortality may be influenced by timing of migration and wintering distribution,...
Seasonal movements and environmental conditions experienced by Pacific halibut in the Bering Sea, examined by pop-up satellite tags
Andrew C. Seitz, Timothy Loher, Jennifer L. Nielsen
2007, Scientific Report of the International Pacific Halibut Commission 84
Currently, Pacific halibut are managed as one population extending from California to the Bering Sea. However, we hypothesize that a spawning subpopulation of Pacific halibut exists in the Bering Sea. In this study, we examined the seasonal migration and depth-specific behavior of Pacific halibut in the Bering Sea, which serve...

The USGS works in cooperation with American Indian and Alaska Native governments to conduct research on (1) water, energy, and mineral resources, (2) animals and plants that are important for traditional lifeways or have environmental or economic significance, and (3) natural hazards. This report describes most of the activities that...
Relative Coastal Change-Potential Assessment of Glacier Bay National Park and Preserve
Elizabeth A. Pendleton, E. Robert Thieler, S. Jeffress Williams
2006, Open-File Report 2005-1247
A change-potential index (CPI) was used to map the relative coastal change-potential of the shoreline to future sea-level fluctuation within Glacier Bay National Park and Preserve (GBNPP) in southeastern Alaska. The CPI ranks the following in terms of their physical contribution to coastal change: geomorphology, regional coastal slope, rate of...

2006, Open-File Report 2006-1094
On October 8, 2005, a M 7.6 earthquake near Muzafarrabad, Pakistan, triggered a landslide that dammed the Karli River and one of its tributaries about 4 km upstream of the confluence of the Karli and Jhelum rivers near the town of Hattian Bala. The smaller dam on the tributary of...
Renesting by dusky Canada geese on the Copper River Delta, Alaska
Thomas F. Fondell, J. Barry Grand, David A.W. Miller, R. Michael Anthony
2006, Journal of Wildlife Management (70) 955-964
The population of dusky Canada geese (Branta canadensis occidentalis; hereafter duskies) breeding on the Copper River Delta (CRD), Alaska, USA, has been in long-term decline, largely as a result of reduced productivity. Estimates of renesting rates by duskies may be useful for adjusting estimates of the size of the breeding...

Basaltic thermals and Subplinian plumes: Constraints from acoustic measurements at Shishaldin volcano, Alaska
Sylvie Vergniolle, Jacqueline Caplan-Auerbach
2006, Bulletin of Volcanology (68) 611-630
The 1999 basaltic eruption of Shishaldin volcano (Alaska, USA) included both Strombolian and Subplinian activity, as well as a “pre-Subplinian” phase interpreted as the local coalescence within a long foam in the conduit. Although few visual observations were made of the eruption, a great deal of information regarding gas velocity,...
USGS Streamgages Linked to the Medium Resolution NHD
David W. Stewart, Alan Rea, David M. Wolock
2006, Data Series 195
The locations of approximately 23,000 current and historical U.S. Geological Survey (USGS) streamgages in the United States and Puerto Rico (with the exception of Alaska) have been snapped to the medium resolution National Hydrography Dataset (NHD). The NHD contains geospatial information about mapped surface-water features, such as streams, lakes,...
Gravity and Aeromagnetic Gradients within the Yukon-Tanana Upland, Black Mountain Tectonic Zone, Big Delta Quadrangle, east-central Alaska
R. W. Saltus, W. C. Day
2006, Open-File Report 2006-1391
The Yukon-Tanana Upland is a complex composite assemblage of variably metamorphosed crystalline rocks with strong North American affinities. At the broadest scale, the Upland has a relatively neutral magnetic character. More detailed examination, however, reveals a fundamental northeast-southwest-trending magnetic gradient, representing a 20-nT step (as measured at a flight height...
Ground water in the Anchorage area, Alaska: Meeting the challenges of ground-water sustainability
Edward H. Moran, Devin L. Galloway
2006, Fact Sheet 2006-3148
Ground water is an important component of Anchorage's water supply. During the 1970s and early 80s when ground water extracted from aquifers near Ship Creek was the principal source of supply, area-wide declines in ground-water levels resulted in near record low streamflows in Ship Creek. Since the importation of Eklutna...

2006, Scientific Investigations Map 2931
The U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program recently completed a national assessment of volatile organic compounds (VOCs) in ground water (Zogorski and others, 2006). As part of this assessment, samples of ambient ground water collected from 3,498 wells during 1985-2002 were selected for characterizing the occurrence of 55...
