Purpose | Scientific objectives of this cruise leg were: (1) to investigate the zone of juncture between the south flank of the Antillean ridge and the north edge of the Venezuelan Basin along the depressed Muertos Trough; (2) to examine structural deformation in the Anegada Trough where the Greater Antilles are joined by the Lesser Antilles and Aves Swell; and (3) to study the northeastern sector of the Puetro Rico Trench where predicted relative plate motion should be transitional between westward underthrusting of the Lesser Antilles and east-west strike-slip motion north of the Greater Antilles. | ||||||||
Location | eastern Greater Antilles, northeast Caribbean Sea, North America, North Atlantic; | ||||||||
Summary | Sub-bottom acoustic profiles were obtained over about 5,840 km of track line in the project area. One dredging station was occupied and three sonobuoy refraction profiles made. Total geophysical track miles: 3,028 (5,840 km); Time Log: #17a; Seismic Log: #17b; Gravity Log: #17c; Bathymetry Log: #17d; and Daily Log: #17e. | ||||||||
