This CD-ROM contains copies of the navigation and field sidescan sonar data collected within the Exclusive Economic Zone (EEZ) surrounding Puerto Rico and off the eastern United States during cruises aboard the R/V FARNELLA. The survey of the Puerto Rico EEZ was completed during one cruise between 4 November and 3 December, 1985. The survey of the EEZ off the eastern United States was completed during five cruises between 2 February and 30 May, 1987. The data were collected as part of the USGS EEZ-SCAN program which was a cooperative mapping program between the US Geological Survey and the Institute of Oceanographic Sciences of the UK. The survey areas included the entire US EEZ of Puerto Rico and the US Virgin Islands as well as of the eastern United States from the Canadian international boundary at Georges Bank to the Bahamian international boundary east of Florida. GLORIA imagery was collected seaward of approximately 400 m water depth.
