The Mid-Atlantic Bight (MAB) extends 1000 km alongshore, from Cape Cod, MA to Cape Hatteras, NC. It includes five major estuarine systems and a wide continental shelf cut by a deep cross-shelf valley and multiple shelf-break canyons. The footprint encompasses 76 million people, or 25% of the US population, and the nation’s highest coastal population density makes increasingly competing demands for marine and coastal resources. The MAB is a dynamic boundary between cooler arctic waters and warmer tropical waters, with complex seasonal physical dynamics. These dynamics structure shellfish and migratory fish habitats that support both commercial and recreational fisheries. Developed watersheds and urban estuaries, impacted by a century of industrialization and growing coastal populations, degrade coastal water quality and diminish recreational economies. To further compound these challenges, climate warming is altering fish and shellfish habitats in the MAB, and new rainfall patterns with more frequent extremes are impacting homes, farms and reservoirs. Our group’s focus is on understanding these dynamics to understand the trajectory of our home in the Mid-Atlantic.
