Washington
Washington's Puget Sound is a complex ecosystem directly adjacent to a robust metropolitan area that scientists from the USGS Western Fisheries Research Center study. Recent surveys have looked at juvenile surf smelt, a key link in the food web that are consumed by predators such as salmon, orca, and many marine birds.

Fine sediment infiltration in Chinook spawning gravels in the Sauk River Basin, Washington
The Issue: There is concern that inherently high finer-grained (small gravel, sand, and silt) sediment loads in the Sauk River system may adversely affect egg-to-fry survival of ESA-listed Chinook salmon in the Sauk River and lower Skagit River Basin. However, there are no quantitative data for the Sauk River basin to assess if fine sediment deposition and infiltration into...
Cheatgrass and Medusahead
Invasive annual grasses, such as cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.
Southeast Sound Groundwater Flow Model
The Issue: Groundwater is an important resource for domestic, commercial, and industrial usage in the Puyallup River and Chambers-Clover Creek Watersheds, and groundwater discharge helps maintain late-summer and early-fall streamflow (baseflow) in many area streams. Consequently, as the population grows, and commercial and industrial activity increase, so does the demand for...

Life History of Pacific Northwest Fishes through Age and Growth Structures
The focus of our research is the ecological analysis of Pacific Northwest fishes through age and growth structures such as: scales, fin rays and otoliths (small calcium carbonate deposits beneath the brain used in hearing and balance that grow in proportion to the overall growth of the fish). These structures are utilized as research tools for understanding life histories and habitat...

Examining controls on the solubility in the ocean of iron from dust and volcanic ash- John Crusius
Biological productivity in the Gulf of Alaska is limited by availability of the micronutrient iron. Dust derived from Alaskan glacial flour and from Asian deserts, and ash from Alaskan volcanoes, episodically supply iron from the atmosphere. This internship would carry out studies on archived material from a variety of dust and ash samples to examine controls on the supply of this...
Effects of Nanophyetus salmincola on the Health and Survival of Puget Sound Steelhead
Low early marine survival rates of Puget Sound steelhead (Oncorhynchus mykiss), the state fish of Washington, have contributed to its dramatic population decline and current listing as a “Threatened Species” under the Endangered Species Act. Determining the cause(s) of this elevated mortality remains a primary objective of the Salish Sea Marine Survival Project, a large US / Canada effort...
Genomic Mechanisms that Underlie Lack of Recovery of Prince William Sound Herring Following the 1990s Collapse
In the decades following the Exxon Valdez Oil Spill (EVOS), it has become increasingly apparent that oil can be toxic at extremely low concentrations to developing fish embryos including herring, where some toxic phenotypes may be apparent during embryogenesis, but some are delayed until later in life. Therefore, acute and lingering oil may act as an insidious selective force within...

Erhardt, John M.; Tiffan, Kenneth F.Geomorphic evolution of a gravel‐bed river under sediment‐starved vs. sediment‐rich conditions: River response to the world's largest dam removal
Understanding river response to sediment pulses is a fundamental problem in geomorphic process studies, with myriad implications for river management. However, because large sediment pulses are rare and usually unanticipated, they are seldom studied at field scale. We examine fluvial response to a massive (~20 Mt) sediment pulse released by...

Aragon-Long, Susan C.; Burkett, Virginia R.; Weyers, Holly S.; Haig, Susan M.; Davenport, Marjorie S.; Warner, Kelly L.A bioenergetics evaluation of temperature‐dependent selection for the spawning phenology by Snake River fall Chinook salmon
High water temperatures can increase the energetic cost for salmon to migrate and spawn, which can be important for Snake River fall‐run Chinook salmon because they migrate great distances (>500 km) at a time when river temperatures (18–24°C) can be above their optimum temperatures (16.5°C). Average river temperatures and random...

In many watersheds, hatchery stocks are released concurrently with the wild population, thus raising the potential for density‐dependent effects. Competition...
Davis, Melanie J.; Woo, Isa; Ellings, Christopher S.; Hodgson, Sayre; Beauchamp, David A.; Nakai, Glynnis; De La Cruz, Susan E.W.Crustal inheritance and a top-down control on arc magmatism at Mount St Helens
In a subduction zone, the volcanic arc marks the location where magma, generated via flux melting in the mantle wedge, migrates through the crust and erupts. While the location of deep magma broadly defines the arc position, here we argue that crustal structures, identified in geophysical data from the Washington Cascades magmatic arc, are equally...
