The NRL (Naval Research Laboratory) Remote Sensing Experiment was carried out in and around Phelps Bank (about 40 miles south - southeast of Nantucket Island) during July, 1982. The exercise was the pilot experiment in a program to examine how and why ocean surface expressions of bathymetric features are sometimes manifest. The specific expressions of interest occur in several types of radar images of the ocean surface. The most interest is in SAR (synthetic aperture radar) images since they appear to be most sensitive to the surface bathymetric signatures; and historically these signatures were first observed in SAR imagery. The exercise involved a surface ship (USNS HAYES) and several aircraft. The HAYES collected meterorological, Oceanographic and Bathymetric data in the operational area. Since this exercise was concerned with bathymetric effects, the precision depth recorder (PDR) system on the HAYES was continually run while in the area bounded by 40 deg and 41 deg N, and 69 deg and 70 deg W. The maximum concentration of data was in the area 40 deg 40 min N to 41 deg N and 69 deg 40 min W. This report describes the data, the instrumentation, its method of collection, and finally presents the data in graphical and tabular form. The data here covers a relatively large area. The same PDR data was more densely scanned in the immediate vicinity of Phelps Bank and plotted in Gordon and Greenewalt (1982).
