Corals Play a key role in cold waters
Corals Play a key role in cold waters Marine scientists are taking their first, up-cloe
look at deep sea corals found on the ocean floor off Nova Scotia.
Corals, which resemble small trees but are really a colony of
simple organisms living on the ocean floor have long been viewed as
a tropical phenomenon. Sophisticated ocean mapping techniques and
subsea video cameras have recently shown large coral reefs in cold
northern waters where the organisms are believed to be as old as
500 years. Canadian fishermen have come to believe that the deep
sea corals provide essential habitat for cod, redfish and several
other marine species. They say the devastation of the coral
colonies caused by heavy bottom dragging fishing gear can be linked
directly to the decline of major fisheries. AUGUST 2, 2000
