COI Funded Project: A Census of Warm, Salty Intrusions From Georges Bank to Cape Hatteras

Proposed Research

Exchange between the waters of the continental shelf and the open ocean is important to a wide range of scientific and societal problems, including determination of shelf water properties, whether the shelf is a source or sink of carbon, and dispersal of pollutants. However, exchange between the shelf and open ocean is so poorly understood that it is uncertain even what the dominant processes are. A potentially important exchange mechanism are lenses of warm, salty open ocean water that are often observed at mid depth over the continental shelf. I propose to use historical data to determine how common such lenses are, when and where they occur, and how large they are. This information will be used to determine the importance of such lenses to exchange between the open ocean and continental shelf.
