k382ar.m77t - MGD77 data file for Geophysical data from field activity K-3-82-AR in Arctic from 08/25/1982 to 09/08/1982

Single-beam bathymetry data along with DGPS navigation data was collected as part of field activity K-3-82-AR in Arctic from 08/25/1982 to 09/08/1982, http://walrus.wr.usgs.gov/infobank/k/k382ar/html/k-3-82-ar.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/k/k382ar/html/k-3-82-ar.bath.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.1982年8月25日至1982年9月8日，科研人员在北极地区开展野外作业K-3-82-AR，期间采集了单波束测深数据（Single-beam bathymetry data）与差分全球定位系统（DGPS）导航数据，相关元数据可通过以下链接查阅：http://walrus.wr.usgs.gov/infobank/k/k382ar/html/k-3-82-ar.meta.html 本数据集由美国海岸与海洋地质计划（Coastal and Marine Geology Program, CMGP）信息库野外作业目录中的以空格分隔的美国信息交换标准代码（ASCII）文本文件重新格式化而来，格式化后采用美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）下属国家地球物理数据中心（National Geophysical Data Center, NGDC）制定的MGD77T格式，原始数据的访问地址为：http://walrus.wr.usgs.gov/infobank/k/k382ar/html/k-3-82-ar.bath.html MGD77T格式包含头文档文件（.h77t）与数据文件（.m77t）两类文件。有关该格式的详细说明，可参阅本元数据文件交叉参考部分所列的相关出版物。
