Lenfest Ocean Program

Supporting Science and Communicating Results

Research Projects

The Lenfest Ocean Program supports marine research that informs policy decisions about the marine environment. Program staff consult with scientists, stakeholders, and decision makers to identify policy-relevant research questions and develop research projects. We do not accept unsolicited proposals.

The Lenfest Ocean Program focuses on the environmental, economic, and social impacts of fishing, fisheries management, and aquaculture.
