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.

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.

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...

Thus, for Sockeye Salmon to colonize a system, projects like dam removals must provide access to lakes. However, if the lakes contain...
