Detailed Description

Research Oceanographer Jessica Lacy investigates the influence of tides, waves, and water levels on wave-exposed tidal salt marshes, helping to understand how these important ecosystems will respond to sea level rise. 

Marshes are important ecosystems, both because they provide habitat for wildlife and birds and because they buffer nearby human communities from flooding. Yet nearly 90% of marshes in California’s San Franciso Bay have been drained or destroyed, leaving these communities vulnerable to flooding from sea level rise. 

Jessica Lacy, Research Oceanographer with the USGS Pacific Coastal and Marine Science Center, studies how tides and waves affect marsh ecosystems in San Francisco Bay, seeking to understand if and how these marshes will be able to keep up with changing ocean conditions. This work helps inform marsh restoration efforts going on in the area, ensuring that they will be successful in future conditions.
