BALTIMORE, MD—The Maryland Geological Survey has embarked on a mission to map the Chesapeake Bay’s bottom, using advanced technology to create a detailed picture of the underwater landscape. This initiative aims to identify suitable areas for oyster restoration, crucial for the health of the Bay’s ecosystem.
Using a custom-built boat equipped with interferometric side-scan sonar, a magnetometer, and a sub-bottom profiler, the team is collecting data on the sediment and underlying structures beneath the water. This equipment provides a comprehensive view of the Bay’s bottom, revealing information about its depth, hardness, and the presence of any metal objects. The data collection process is meticulous and involves following precise lines across the Bay and its tributaries. This method, akin to “mowing the lawn,” ensures complete coverage of the area. The team often works in winter months, navigating challenging conditions such as cold temperatures, ice, and wind to avoid interference from crab pot floats and other boats.
Stephen Van Ryswick, Director of the Maryland Geological Survey, emphasized the importance of this work: “We need this data to determine where the suitable bottom is…We look at where the new data gives us the most value, where new data can help us make decisions.”…
