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.

    Estuarine Ecosystem Recovery in Puget Sound

    A clean and abundant sediment supply is critical for building and maintaining viable estuarine and wetland habitats.
