k195hw.m77t and k195hw.h77t: MGD77T data and header files for single-beam bathymetry data for field activity K-1-95-HW in in Hawaii from 06/14/1995 to 06/18/1995

Metadata Updated: November 12, 2020

Single-beam bathymetry data along with DGPS navigation data was collected as part of the U.S. Geological Survey cruise K-1-95-HW. The cruise was conducted in Oahu, Hawaii from June 14 to June 18, 1995. The chief scientist was Mike Torresan from the USGS Coastal and Marine Geology office in Menlo Park, CA. The purpose of this cruise was to conduct an integrated study on the distribution and character of dredged materials as well as the effects of dredged material on the marine environment. A three phase study provided information to evaluate the effects on seafloor substrate and the benthic fauna. The studies include geophysical profiling and imaging, bottom photography, sampling, chemical and physical analyses of sediment, and evaluations of the benthic population, population density, and adverse impacts to the benthic fauna. The geophysical source was an ODEC 3.5 kilohertz (kHz) echosounder. 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/k195hw/html/k-1-95-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.
