| | USGS OFR 02-002: Summary Report - Block Island Sound (Site not responding. Last check: 2007-10-13) |
 | | An extensive high-resolution, seismic-reflection survey was conducted in Block Island Sound (Figure 1) by the U.S. Geological Survey, in cooperation with the State of Connecticut Geological and Natural History Survey, Department of Environmental Protection (D.E.P.), to determine the stratigraphic framework and Quaternary history of the sound. |
 | | The bedrock and coastal-plain strata are unconformably overlain by glacial drift. |
 | | Block Island, Fishers Island, and Long Island are capped by two glacial drift sheets representing two ice advances, one of late Wisconsinan age and one that predates the late Wisconsinan (Donner, 1964; Sirkin 1971, 1976, 1982; Mills and Wells, 1974). |
