Single-beam bathymetry, magnetics, and gravity data along with transit satellite navigation data was collected as part of field activity L-9-81-AA in Aleutian Arc, Alaska from 07/19/1981 to 08/13/1981, http://walrus.wr.usgs.gov/infobank/l/l981aa/html/l-9-81-aa.meta.html 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/l/l981aa/html/l-9-81-aa.bath.html http://walrus.wr.usgs.gov/infobank/l/l981aa/html/l-9-81-aa.grav.html http://walrus.wr.usgs.gov/infobank/l/l981aa/html/l-9-81-aa.mag.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).
