Information to be Derived:
Summary of Activity and Data Gathered: This was the second cruise to the Dominican Republic as part of the five-year agreement between USGS and DGM. We returned to Samana Bay for seismic equipment of greater penetration in order to see basement. We didn't. The thickness of sediment here appears to be similar to the Cibao Valley (within the same structural trend on-shore) where cores have penetrated more than 7 km of sediment. In the Manzanillo-Monte Cristi area we concentrated our studies on a spit where heavy minerals (particularly titanius) have been concentrated. We evaluated the extent of this deposit offshore. Shipek grab samples: 40; Beach samples: 14; Piston cores: 12; Vibracores: 4.
