The NOAA Marine Debris Program (MDP), authorized in the Marine Debris Act (33 U.S.C. 1951-1958), provides funding to support eligible organizations to conduct research directly related to marine debris through field, laboratory, and modeling experiments. The MDP invites applications for research funding in any of three areas of focus: research that explores the ecological risk associated with marine debris and determines debris exposure levels; research that examines the fate and transport of marine debris; and/or research that quantifies habitat impacts resulting from marine debris and the gains in ecosystem services that result when debris is removed. Projects may address one or more of these research priorities and should be original, hypothesis-driven projects that have not previously been addressed to scientific standards. Successful proposals through this solicitation will be funded through cooperative agreements. Funding of up to $1,500,000 is expected to be available for Marine Debris Research grants in Fiscal Year 2019 (FY19). Typical awards will range from $150,000 – $250,000. Funding for this grant competition comes through the NOAA Marine Debris Program as appropriations to the Office of Response and Restoration, National Ocean Service. Proposals are due December 14, 2018.
