HLY-08-02 Raw 75 KHz ADCP Data [Ashjian/LDEO]

This dataset includes data from the 75 KHz ADCP system onboard the US Coast Guard Cutter Healy during the Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program (BEST-BSIERP) 2008 0802 (late spring) cruise. BEST-BSIERP together are the Bering Sea project. The ADCP system measures currents in the depth range from about 30 to 300 m in good weather. In bad weather or in ice, the range is less, and sometimes no valid measurements are made. The individual data files have been collected into tar files by day according to the sequence number. The following is the list of file extensions and their meaning of the data files contained in the tar files: ENR - Raw Binary ADCP Data
ENS - Binary ADCP Data
ENX - Binary Ensemble Data
STA - Short Term Averaged Data
LTA - Long Term Averaged Data
N1R - Raw NMEA ASCII Data
N2R - Raw NMEA ASCII Data
NMS - Averaged Nav Data

本数据集汇集了美国海岸警卫队雪莉号巡逻舰在贝林海生态系统研究-贝林海综合生态系统研究计划（BEST-BSIERP）2008年0802（晚春）航次期间，由75千赫ADCP系统收集的数据。BEST-BSIERP合称为贝林海项目。ADCP系统在晴朗天气下测量从约30至300米深度的水流。在恶劣天气或冰区条件下，测量范围会减小，有时甚至无法获取有效数据。根据序列号，每日的数据文件已被收集并打包成tar文件。以下为tar文件中数据文件扩展名及其含义列表：ENR - 原始二进制ADCP数据
ENS - 二进制ADCP数据
ENX - 二进制集合数据
STA - 短期平均数据
LTA - 长期平均数据
N1R - 原始NMEA ASCII数据
N2R - 原始NMEA ASCII数据
NMS - 平均导航数据
