The United States manages millions of square miles of coastal ecosystems that support a variety of recreational, commercial and subsistence activities. Sea Grant helps residents, natural resource managers and businesses protect and restore healthy coastal habitats for continued ecosystem and public well-being.

Meet Sea Grant Experts Working for Healthy Coastal Ecosystems

Jenny Hofmeister, Ph.D.

Post-Doctoral Researcher, Scripps Institution of Oceanography - To keep endangered white abalone alive, California Sea Grant-funded researcher Jenny Hofmeister studies the ecology and behavior of southern California octopuses to address how we can outsmart the octopus—abalone’s most voracious predators in deep water.

"Predation is natural, but in order to successfully restore white abalone, we need to give them a head start."

Michael Wetz, Ph.D.

Associate Professor of Marine Biology, Texas A&M University - Corpus Christi - Michael's Texas Sea Grant-funded research focuses on the health of Baffin Bay, an impaired estuary in South Texas that experiences persistent harmful algal blooms and hypoxia. He integrates citizen science with experiments to identify key influences on water quality, information that is used to develop mitigation strategies.

"The community support for our research has been incredible. For nearly six years, we've worked hand-in-hand with community members. This support gives me hope that we can solve the challenges facing Baffin Bay."

Jessica Brown

Stormwater Specialist, Georgia Sea Grant - As lead of the Georgia Sea Grant Stormwater Program, Jessica works with coastal communities and decision makers to implement cutting-edge management strategies that treat polluted runoff and reduce flooding.

"Providing communities with the tools and knowledge needed to invest green stormwater infrastructure solutions will result in benefits to ecosystems, water resources, public health, and quality of life. We find solutions to the pollution.”

California Sea Grant publishes new research on microplastics in San Diego estuary fish

In a study led by California Sea Grant Extension Specialist Theresa Talley, researchers found that nearly a quarter of fish sampled from a creek that flows into San Diego Bay contain microplastics. This work, which was recently published in the journal PLOS ONE, examined plastics in coastal sediments and three species of fish.

Great Lakes Resurgence

Cleanup efforts bring life to local waterfronts

Revitalization breaks through in this photo essay from National Geographic photographer Peter Essick, in collaboration with the Great Lakes Sea Grant Network, demonstrating the renewed majesty of the Great Lakes.

 Take a visual tour of the restoration and resurgence of Great Lakes tributaries that were designated as Areas of Concern under the 1987 Great Lakes Water Quality Agreement. These tributaries were pinpointed due to significant pollution and habitat problems, but with funding from the Great Lakes Restoration Initiative, Areas of Concern are getting cleaned up and habitat is being restored.

An ecological investment is bringing life back to the aquatic environment. Tourism, recreation, and development are returning to the basin’s rivers, harbors, and lakes.

NOAA, partners release harmful algal bloom forecast for western Lake Erie

A large summer bloom is predicted

The Lake Erie Harmful Algal Bloom (HAB) Seasonal Forecast, produced by NOAA and released with Ohio Sea Grant, gives coastal managers, lake users, and drinking water facility operators a general sense of the potential severity of the upcoming bloom season. NOAA is forecasting a large bloom for 2019, with a severity index greater than 7. The index is based on the bloom’s biomass – the amount of harmful or toxic algae – over a sustained period.  Last year’s bloom had a severity of 3.6 and the 2017 bloom had a severity of 8.
