HLY-07-01 Raw Knudsen 320B/R Depth Sounder Data [Sambrotto/LDEO]

This dataset includes data from the Knudsen 320B/R Depth Sounder system onboard the US Coast Guard Cutter Healy during the Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program (BEST-BSIERP) 2007 cruise. BEST-BSIERP together are the Bering Sea project. The Knudsen depth sounder records the 3.5 kHz data (Sub Bottom Profile). The various types of data files have been organized into gzipped daily tar files. The following is a list of the file extensions and their meaning: .keb - Binary Knudsen Playback File .kea - ASCII log of depth, settings and environmental data .sgy - Binary SEG-Y extended Seismic format The Knudsen_serial_out_format.bmp data file shows the format of the data files.

本数据集涵盖2007年白令海生态研究-白令海综合生态研究计划（BEST-BSIERP）航次中，美国海岸警卫队希利号搭载的克努森320B/R测深仪系统采集的相关数据。BEST-BSIERP整体即为白令海项目。该测深仪可记录3.5 kHz海底剖面（Sub Bottom Profile）数据。各类数据文件已被整理为gzip压缩的每日tar归档文件。以下为各文件扩展名及其含义：.keb——二进制克努森回放文件（Binary Knudsen Playback File）；.kea——包含水深、仪器设置与环境数据的ASCII日志文件；.sgy——采用拓展地震SEG-Y格式的二进制文件。Knudsen_serial_out_format.bmp文件展示了本数据集内数据文件的格式规范。
