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.

Land use and tsunami hazards in the Pacific Northwest

Tsunamis have the potential to cause considerable damage to communities along the U.S. Pacific Northwest coastline. As coastal communities expand over time, the potential societal impact of tsunami inundation changes.

To understand how community exposure to tsunami hazards may change in coming decades, we projected future development (i.e. urban, residential, and rural), households, and...

National Parks North Coast and Cascades Network Critical Loads

Nutrients such as nitrogen are essential for plant and animal growth and nourishment, but overabundance can cause adverse effects. Excess amounts of nitrogen from the atmosphere can cause a lake to go through eutrophication, the process in which excess nitrogen triggers a series of events that cause a lake to become fatally low in dissolved oxygen. Alpine lakes are especially sensitive to...
