  NOAA explorers Caves in Bermuda

  Bermuda (Global Adventures): The Green Bay Cave in Bermuda the longest known cave on the island and the target of a NOAA expedition running until September 30, 2009. Deep water marine caves represent one of the Earth’s last largely unexplored frontiers of undiscovered fauna.
  
  More than 150 limestone caves are known from the island of Bermuda, many of which have extensive, but relatively shallow submerged portions that connect to the sea via tidal springs along the coastline. These inland caves are inhabited by a number of diverse eyeless and colorless crustaceans and other invertebrates. Many of these organisms are “living fossils” and some are most closely related to deep-sea organisms, so a press release on NOAA’s ocean explorer website
  
  The existence of ancient cave species and the fact that all known Bermuda caves were dry and air filled during Ice Age periods of lower sea level suggests that an alternate, now deep water cave habitat must have existed in Bermuda.
  
  While previous investigations of marine caves have been limited to those within depths of up to 165 feet (50 meters), current research suggests that caves can occur at almost any depth within the sea. The geological history of Bermuda coupled with biological evidence indicates a strong possibility for the presence of deepwater caves near the island.
