Additional Documentation: NGDC has multibeam bathymetric data for this cruise, however the tracklines, found here in GEODAS do not exactly correspond to the multibm data available. Single beam bathymetric data from DATE/TIME 8502190757983 to 8502191623050 are, from URI processed multibm data with an interpolation scheme in 1 MINUTE, EXTRACTIONS CLOSEST TO THE MINUTE (VERTICAL BM). Multibeam data for this, survey only available between 107.756 and 105.786 degrees west.
