NOAA Ocean Explorer: Battle of the Atlantic: Archaeology of an Underwater WWII Battlefield:

NOAA and its research partners are surveying, for the first time since they sank more than 70 years ago, the remains of two ships that were involved in a convoy battle off North Carolina during World War II. The “Battle of the Atlantic: Archaeology of an Underwater WWII Battlefield” expedition is part of an ongoing research project to document and highlight a little-known, but important, chapter in the nation’s maritime history.
