Mallows Bay

The National Aquarium


In November 2019, Calvert County’s Mallows Bay, a stunning and ghostly ship graveyard now teeming with aquatic life, became America’s 14th national marine sanctuary. Listen in to learn more about this fascinating Chesapeake treasure.


As chief executive officer, John Racanelli leads a team of 600 full and part-time employees and 1,000 volunteers in pursuing the National Aquarium’s mission to inspire conservation of the world’s aquatic treasures. More than 1.5 million people annually visit the Aquarium’s venue in Baltimore, Maryland, while millions more are touched by the Aquarium’s education programs, outreach activities, social media campaigns and conservation initiatives.
