a298sc.m77t and a298sc.h77t: MGD77T data and header file for single-beam bathymetry for field activity A-2-98-SC in Santa Monica Bay from 08/23/1998 to 08/31/1998

Single-beam bathymetry data along with GPS navigation data was collected as part of the U.S. Geological Survey cruise A-2-98-SC. The cruise was conducted in Santa Monica Bay from August 23 to August 31, 1998. The chief scientists were Homa Lee and Brian Edwards from the USGS Coastal and Marine Geology office in Menlo Park, CA.
The purpose of this cruise was to collect box core, gravity and piston core samples to understand anthropogenic affects on sedimentation. 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/a/a298sc/html/a-2-98-sc.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.
