The coastal waters off the Delmarva Peninsula extend from the mouth of the Chesapeake Bay at Fisherman Island, VA to the entrance to the Delaware Bay at Cape Henlopen, DE, encompassing most of Delaware and the Maryland and Virginia Eastern Shores. Tourism accounts for the majority of the ocean economy in the Delmarva Atlantic counties and contributes nearly $800 million in GDP annually. Visitors to Delaware beaches, Maryland and Virginia barrier islands and other locations along the coast depend on MARACOOS coastal observing for safety during hazardous weather and poor water quality events. Data generated by MARACOOS partners improve the safety of residents and visitors in the Delmarva region by shortening Coast Guard search times and predicting and monitoring severe storms.
