About the Program
Identification, Mapping and Assessment of Derelict Fishing Gear in the Chesapeake Bay
A pilot project using side scan sonar and other remote sensing and imaging technologies to identify, map, and assess the prevalence and impacts of derelict fishing gear (DFG) and other submerged debris in selected areas of the Chesapeake Bay.
The identification and mapping of DFG and other submerged marine debris is performed using remote sensing (e.g., side scan sonar, magnetometer, and other digital imaging technologies). Study design for the project is informed by consultation with the Northwest Straits Commission. In situ observations for target verification, assessment, and classification are accomplished using underwater videography (drop-down cams, video and sonar equipped remotely operated vehicles), and SCUBA divers assisted by blue wave sonar to vector to targets in low visibility conditions. An assessment of socioeconomic impacts will also be performed in partnership with the University of Maryland Chesapeake Biological Laboratory .
The results of this pilot project will be used to develop a comprehensive effort to locate and remove detrimental derelict crab pots throughout the Bay.
This project is housed within NOAA's Ocean Service, Office of Response and Restoration, Chesapeake Bay Office. It has been funded by the Marine Debris Program.
