PurposeResearch
ObjectivesSecond year of a six-year co-operative research programme between the United States Geological Survey (USGS) and IOS to survey the exclusive economic zone (EEZ).

GLORIA sonar coverage of US EEZs in the Gulf of Mexico and off Puerto Rico (also part of Cayman Trough). Also, single channel seismic reflection profiles with 80 or 160 cubic inch airgun, 3.5kHz high resolution profiles and 10kHz narrow beam echo-sounding profiles recorded, along with continuous magnetic anomaly profiles.

Objectives:
The area to be covered extended from near the shelf break to the median line with Mexico, and the overlapping coverage was intended to include part of the West Florida Escarpment and Desoto Canyon, with a main objective to complete the sonar mosaic of the Mississippi Fan.
