SEISMIC REFRACTION INVESTIGATIONS IN SELECTED AREAS OF NARRAGANSETT BAY, RHODE ISLAND
Abstract
Seven reversed refraction profiles were fired in 4 shallow water areas in Narragansett Bay, R. I. Results are presented in the form of reversed travel time graphs and cross sectional representations of the strata. Seismic velocities and layer depths are shown in tabular form. The thickness of the sediment layer varies from about 14 to 52 m, with the thicker portions generally occurring in the northernmost area. The depth of the upper refracting horizon, the boundary between the sediment layer and the intermediate layer, varies from 23 to 45 m below mean low water. The intermediate layer varies in thickness from about 290 m at the northern end of the bay to 58 m toward the south. The lower refracting horizon, the boundary between the intermediate layer and the third layer, ranges in depth from 85 to 340 m below the datum level.
