This data set contains a grid representing Holocene fluvial, estuarine (Qfe) and nearshore marine (Qmn) sediment thickness (in meters) offshore of western and southern Martha's Vineyard and north of Nantucket. 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 are surficial sediments that also fill valleys and partially blanket the sea floor.

This file is a 32-bit GeoTIFF image compressed using the LZW compression format with a world file. To utilize these data an image processing or GIS software package capable of importing a 32-bit TIFF image with LZW compression is needed. Standard image viewing software cannot translate a 32-bit image.
