Stellwagen Bank National Marine Sanctuary Celebrates its 20th Anniversary

摘要

It's been twenty years since Stellwagen Bank and its surrounding waters off the Massachusetts coast was designated a National Marine Sanctuary. Named for Henry Stellwagen, the US Navy lieutenant who mapped the bank in 1854, the underwater plateau has been known to mariners since at least the 1700s, when sections of it first appear on nautical charts. In 1992 Congress designated the area (638 square nautical miles) as the country's tenth National Marine Sanctuary (NMS).
