k185ar.m77t and k185ar.h77t: MGD77T data and header files for single-beam bathymetry data for field activity K-1-85-AR in the Arctic from 09/04/1985 to 09/04/1985

Single-beam bathymetry data along with SINS navigation data was collected as part of the U.S. Geological Survey cruise K-1-85-AR. The cruise was conducted in the Arctic on September 4, 1993. The chief scientists were Erk Reimnitz and Peter Barnes from the USGS Coastal and Marine Geology office in Menlo Park, CA.
The overall purpose of this study and the geophysical source are unknown.
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/k185ar/html/k-1-85-ar.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.

本数据集包含美国地质调查局（U.S. Geological Survey, USGS）航次K-1-85-AR采集的单波束测深数据与捷联式惯性导航系统（SINS）导航数据。该航次于1993年9月4日在北极地区开展，首席科学家为来自美国地质调查局加利福尼亚州门洛帕克海岸与海洋地质办公室的Erk Reimnitz与Peter Barnes。

本研究的整体目标及地球物理数据源均尚不明确。

本数据集由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）国家地球物理数据中心（National Geophysical Data Center, NGDC）制定的MGD77T格式，从存储于海岸与海洋地质计划（Coastal and Marine Geology Program, CMGP）信息库野外活动目录（网址：http://walrus.wr.usgs.gov/infobank/k/k185ar/html/k-1-85-ar.meta.html）中的空格分隔ASCII文本文件转换而来。MGD77T格式包含头文件（文档文件，后缀为.h77t）与数据文件（后缀为.m77t）。有关该格式的更多细节，可参阅本元数据文件交叉参考部分所列的相关出版物。
