Cruise summary report
|Ship name (ship code)||RV Farnella (74AE)|
|Cruise period||1985-08-07 — 1985-09-01|
|Port of departure||Miami, United States|
|Port of return||New Orleans, United States|
|Objectives||Second 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.
1. To complete a reconnaissance survey using lapping sidescan data of the western part of the Gulf of Mexico lying within the US 200 nautical mile zone and in waters deeper than approximately 500m.
2. To complete sonar and seismic cover of the complex contintental slope west of the Mississippi Fan, extensively deformed during recent salt tectonism.
3. To complete the donar cover of the East Breaks Slide, a major submarine failure, first surveyed in part during the 6/82 Farnella cruise.
