Great Salt Lake Elevations

Great Salt Lake Elevations

The United States Geological Survey (USGS) has been collecting water-surface-elevation data from Great Salt Lake since 1875 and continuously since October 1902. The north part of the lake has been monitored since April 1966.

In July 2021, the southern portion of the Great Salt Lake reached a new historic low, with average daily water...

Quantifying Nutrient Mass and Internal Cycling in Great Salt Lake

The Great Salt Lake (GSL) is an indispensable economic and ecological resource.  It provides critical habitat and food for millions of migratory birds, and generates nearly $200 million per year from recreational activities and the brine shrimp harvest industry (Bioeconomics, 2012).  These uses, habitat and aquaculture, rely on a balanced supply of nutrients in the Great Salt Lake to support...

San Francisco Bay Bathymetry

Bathymetry of a dynamic tidal estuary, such as San Francisco Bay, provides the observable linkage between anthropogenic modifications of the landscape—such as evolving land use practices, flood control, and water diversions—and natural forces of climate-driven river flow, sea level change, tides, and wind. By examining our record of hydrographic surveys, spanning over 150 years, we can gain...

Coastal Climate Impacts

The impacts of climate change and sea-level rise around the Pacific and Arctic Oceans can vary tremendously. Thus far the vast majority of national and international impact assessments and models of coastal climate change have focused on low-relief coastlines that are not near seismically active zones. Furthermore, the degree to which extreme waves and wind will add further stress to coastal...

Dynamic coastlines along the western U.S.

The west coast of the United States is extremely complex and changeable because of tectonic activity, mountain building, and land subsidence. These active environments pose a major challenge for accurately assessing climate change impacts, since models were historically developed for more passive sandy coasts.
