Ocean currents measured by Shipboard Acoustic Doppler Current Profiler (SADCP) from global oceans as part of the Joint Archive for Shipboard ADCP holdings from 16 June 1985 to 23 March 2001 (NODC Accession 0000755)

Absolute U- and V-component ocean current vectors from Shipboard Acoustic Doppler Current Profilers (SADCP), as both a high frequency sampling (nominally 5 minutes with 8 m depth bins) and an averaged subset (hourly time and 10 m depth means), are provided for the global oceans. The depth range is typically from 20 to 300 m although recent technology has allowed penetration to over 1 km. The high frequency samples along with ancillary parameters are provided in the Common Oceanographic Data Access System (CODAS) binary format. The standard (averaged) subset is stored in ASCII. This dataset represents the cruises acquired from 16 June 1985 through 23 March 2001 at the Joint Archive for SADCP, a collaboration of NOAA and the E.Firing ADCP Laboratory at the University of Hawaii. The data have been contributed by both US and international organizations.

本数据集提供全球海洋的船载声学多普勒海流剖面仪（Shipboard Acoustic Doppler Current Profilers, SADCP）观测得到的绝对U、V分量海流矢量，包含两类数据子集：一类为高频采样数据（标称采样间隔5分钟，深度分层8米），另一类为平均数据子集（按小时时间平均、10米深度平均）。数据集的典型探测深度范围为20至300米，不过随着技术进步，目前已可实现超过1000米的探测深度。高频采样数据连同辅助参数以通用海洋学数据访问系统（Common Oceanographic Data Access System, CODAS）二进制格式存储，标准（平均）子集则以ASCII格式存储。本数据集源自1985年6月16日至2001年3月23日期间，由美国国家海洋和大气管理局（NOAA）与夏威夷大学E.弗林声学多普勒海流剖面仪实验室合作建立的SADCP联合档案库所收录的航次数据，相关数据由美国及国际多家机构共同提供。
