| Description |
Single-beam bathymetry data along with DGPS navigation data was collected as part of the U.S. Geological Survey cruise K-2-94-HW. The cruise was conducted in Mamala Bay, Offshore Honolulu, Oahu, Hawaii from May 16 to May 23, 1994. The chief scientists were Mike Torresan and Monty Hampton from the USGS Coastal and Marine Geology office in Menlo Park, CA. The purpose of this cruise was to sample and groundtruth the 1993 Acoustic data of the seafloor of Mamala Bay over the US Corps of Engineers Deep Ocean dredged material disposal sites used by Pearl and Honolulu Harbors. The geophysical source is a 12 kilohertz (kHz) Raytheon DSF-6000 fathometer. These data are reformatted from space-delimited ASCII text files located in the Coastal and Marine Geology Program (CMGP) InfoBank field activity catalog at http://walrus.wr.usgs.gov/infobank/k/k294hw/html/k-2-94-hw.meta.html into MGD77T format provided by the NOAA's National Geophysical Data Center(NGDC). The MGD77T format includes a header (documentation) file (.h77t) and a data file (.m77t). More information regarding this format can be found in the publication listed in the Cross_reference section of this metadata file. [More]
