Geological Framework Data from Long Island Sound, 1981-1990: A Digital Data Release

As part of this program, a highly successful regional-scale study of theSeismic reflection acquisition illustration geologic framework was completed. Reconnaissance high-resolution seismic reflection data were collected and used to establish the basic stratigraphy within the Sound and to map the major geologic units (Needell and Lewis, 1984; Lewis and Needell, 1987; Needell and others, 1987); field verification of the geologic interpretations of the seismic profiles was primarily accomplished with vibratory cores (Williams, 1981; Thomas, 1985; Neff and others, 1989).

These interpretations were in turn used to produce basin-wide syntheses of the late Quaternary depositional history (Lewis and Stone, 1991; Stone and others, 1998; Lewis and DiGiacomo-Cohen, 2000). Unfortunately, the original seismic records and core logs were generated only in analog form. These unique paper documents, which are still under demand for industrial applications and academic research, are fragile and have become ragged from frequent use.
