This data set contains a grid representing the elevation to the late Wisconsinan to early Holocene regressive unconformity (Ur) offshore of western and southern Martha's Vineyard and north of Nantucket. These data are useful for assessing relations between geologic framework and sea-bed morphology. The late Wisconsinan regressive unconformity (Ur) locally merges with Holocene transgressive unconformity (Ut) and defines the upper surface of glacial deposits.

The imagery 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.
