Coastal Ecosystem Response to Sea-level Rise

USGS WERC’s Dr. Karen Thorne, her team of reseachers, and her partners are currently taking a local site network approach to describe current and future conditions and projected responses of coastal ecosystems to sea-level rise and other stressors. The Coastal Ecosystem Response to Climate Change (CERCC) program’s goal is to understand how ecosystems vary in their ability to keep up with sea-...

Land Treatment Digital Library

The LTDL was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The...

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...

Land Use and Climate Change Team

We are a research team focusing on understanding the rates, causes, and consequences of land change across a range of geographic and temporal scales. Our emphasis is on developing alternative future projections and quantifying the impact on environmental systems, in particular, the role of land-use change on ecosystem carbon dynamics.

We are interested in how land-use and climate...

Uranium in Groundwater

The Issue: Recent groundwater monitoring in northeastern Washington has shown elevated levels of uranium in several community water systems and in private wells. Naturally occurring uranium is associated with granitic and metasedimentary rocks, as well as younger sedimentary deposits, that occur in northeastern Washington. The occurrence and distribution of uranium in...

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...

Spokane Valley - Rathdrum Prairie

The Spokane Valley/Rathdrum Prairie aquifer, which extends across Idaho and Washington, is the sole source of drinking water for more than 450,000 people. Recently submitted water-rights requests would substantially increase withdrawals from the aquifer. The public and state resource management agencies need an improved understanding of the SVRP hydrologic system in order to ensure appropriate...

Faunal assemblages and multi-scale habitat patterns in headwater tributaries of the South Fork Trinity River - an unregulated river embedded within a multiple-use landscape

Headwaters can represent 80% of stream kilometers in a watershed, and they also have unique physical and biological properties that have only recently been recognized for their importance in sustaining healthy functioning stream networks and their ecological services. We sampled 60 headwater tributaries in the South Fork Trinity River, a 2,430 km2...
