This data set contains a grid representing Holocene fluvial, estuarine (Qfe), nearshore marine (Qmn), and deepwater marine (Qmd) sediment thickness (in meters) beneath Vineyard and western Nantucket Sounds. These data are useful for assessing relations between geologic framework, sea-bed morphology, and sediment textural trends. Qfe is the lowermost Holocene sedimentary deposit that partially fills the fluvial valleys incised into the surface of Pleistocene glacial drift. Qmn and Qmd are surficial sediments that also fill valleys and partially blanket the sea floor.
