Bradford Butman, Tammie J. Middleton, E. Robert Thieler, and William C. Schwab
This report presents maps of the sea floor topography, shaded relief, and backscatter intensity of the Hudson Shelf Valley at a scale of 1:150,000 based on multibeam echo-sounder data. The multibeam surveys were conducted aboard the vessel Frederick G. Creed in fall 1996, 1998, and spring 2000. The maps are presented on two sheets in PDF format (see links below).
The discussion on the map sheets is also available in HTML (with links to individual figures), PDF [133 kb], or TEXT-ONLY version. The Figures page includes thumbnails and links to all the figures in this report; open this page to preview and link to figures while reading the text.
