Rocky intertidal species diversity along the Kenai Peninsula, Alaska: 2003 - 2004

Anne Salomon & Jennifer Ruesink
We investigated the relative roles of natural factors and shoreline harvest leading to localized declines of the black leather chiton, Katharina tunicata, on the Kenai Peninsula, Alaska. Field surveys of the significant predictors of K. tunicata across 11 sites suggest that its current spatial variation is significantly related to human exploitation and sea otter predation. Traditional ecological knowledge further revealed that several benthic marine invertebrates (sea urchin, crab and clams) have declined sequentially, with reduced...

Recovery monitoring and restoration of intertidal oiled mussel beds in Prince William Sound, Alaska: 1989 - 2000

Malin Babcock, Patricia Harris, Mark Carls, Christine Broderson & Stanley Rice
Study History: After the 1989 Exxon Valdez oil spill, many researchers began measuring hydrocarbon concentrations in mussels, sediment, and other matrices in Prince William Sound to assess resource damage. The specific focus of this project was dense aggregations of intertidal mussels (Mytilus trossulus) within the slick trajectory. Oil accumulated in these filter-feeders; total polynuclear aromatic hydrocarbon concentrations were high in 1989 and remained relatively high for several years in mussel beds on unconsolidated sediment. The...

Forage fish diet in Prince William Sound, Alaska: 1994 - 1996

Molly Sturdevant
The Forage Fish Diet Overlap component of the Alaska Predator Ecosystem Experiment (APEX) investigated the trophic interactions of forage fish prey of seabird populations which were impacted during the Exxon Valdez oil spill. We analyzed more than 5000 specimens of 14 forage species, and zooplankton and epibenthic prey samples from Prince William Sound (PWS), 1994-96. Forage fish were collected monthly in western PWS with purse seines in 1994 and in three regions of PWS (southwestern,...

Assessment of Bivalve Recovery on Treated Mixed-Soft Beaches In Prince William Sound, 1989-1997

Dennis Lees & William Driskell
National Oceanic and Atmospheric Administration treatment effects studies from 1989 through 1997 suggested that bivalve assemblages on beaches in Prince William Sound treated with high-pressure washing were severely injured in terms of abundance, species composition, and function. Restoration Project 040574 assessed the generality and persistence of this apparent injury to this assemblage. We found that the initial conclusions were accurate, indicating that a considerable proportion of mixed-soft beaches in treated areas of the sound remained...

Resistance of naturally spawned pink salmon eggs to mechanical shock

John Thedinga, Mark Carls, Jacek Maselko, Ronald Heintz &
Routine hydraulic sampling of pink salmon eggs (Oncorhynchus gorbuscha) is the subject of a long-running dispute over impacts of the Exxon Valdez oil spill on embryo survival in Prince William Sound, Alaska, because relationships between the time of spawning, sensitivity of eggs to mechanical damage, and sample timing were unclear. Previous laboratory or hatchery studies demonstrate that resistance of eggs to mechanical damage increases with maturity, but applicability to natural populations requires an understanding of...

Pacific Herring (Clupea pallasii) Stable Isotope Tracers: Food Webs of Fishes-Prince William Sound, Alaska (1994-1998)

Thomas C. Kline
This project is a component of the Sound Ecosystem Assessment (SEA) program, a multi-disciplinary effort to acquire an ecosystem level understanding of the marine and freshwater processes that interact to constrain levels of fish, marine bird, and marine mammal production in Prince William Sound (PWS). Research conducted under the Sound Ecosystem Assessment project (SEA, /320) has shown that Pacific herring have significant dependence on Gulf of Alaska carbon. Accordingly, herring are subject to changes in...

Ecology and demographics of Pacific sand lance in Lower Cook Inlet, Alaska: 1997 - 1999

Martin Robards & John Piatt
Study History: The purpose of this study was to characterize the basic ecology, distribution, and demographics of sand lance in lower Cook Inlet. Recent declines of upper trophic level species in the northern Gulf of Alaska have been linked to decreasing availability of forage fishes. Sand lance is the most important forage fish in most nearshore areas of the northern Gulf. Despite its importance to commercial fish, seabirds, and marine mammals, little is known or...

Observer classification of live, mechanically damaged, and dead pink salmon eggs

Mark Carls, John Thedinga & Robert Thomas
Susceptibility of pink salmon (Oncorhynchus gorbuscha) eggs to mechanical damage (shock) was studied to test the ability of observers to discriminate among live, dead, and shocked eggs. In a series of six laboratory trials, the mean error rate in discrimination did not exceed 12% and was less than or equal to 3.5% in 4 of 6 trials. The most common error was misclassification of shocked eggs as live (less than or equal to 9 +/-...

Summary of influenza A subtypes in wild birds from GenBank and 49 studies

& Sarah Olson
Wild aquatic birds are recognized as the natural reservoir of avian influenza A viruses (AIV), but across high and low pathogenic AIV strains, scientists have yet to rigorously identify all competent hosts and subtypes. We examined 11,870 GenBank records to provide insight into patterns of global AIV subtype diversity and richness. Further, we conducted an extensive literature review and communicated directly with scientists to accumulate data from 49 study locations and over 250,000 birds. We...
