| Purpose | To ensonify the central region of the Cayman Trough with the GLORIA sidescan system. | ||||||||
| Location | Cayman Trough, Cayman Islands, Caribbean Sea, North America, North Atlantic; | ||||||||
| Summary | The Cayman Trough is a narrow rectangular deep which contains a sea floor spreading system. The survey took place over the coastal region of the spreading ridge and along one line to the eastern extremity of the Trough. These data provide detailed information of the history of spreading in the trough and thus the nature of the northern Caribbean plate boundary. | ||||||||
