Ocean currents measured by Shipboard Acoustic Doppler Current Profiler (SADCP) from global oceans as part of the Joint Archive for Shipboard ADCP holdings from 13 September 1999 to 28 April 2007 (NODC Accession 0036863)

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 13 September 1999 through 28 April 2007 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. A total of 78 cruises on 12 ships (1.1 gigabytes) are included.本数据集收录船载声学多普勒海流剖面仪（Shipboard Acoustic Doppler Current Profilers, SADCP）观测得到的全球海洋绝对U、V分量海流矢量，包含两类数据子集：其一为高频采样数据集（标称采样间隔5分钟，深度分层8米）；其二为平均化数据集，采用小时级时间分辨率与10米深度均值进行平均处理。观测深度范围通常为20至300米，不过随着技术迭代，当前已可实现超过1000米的探测深度。高频采样数据及其配套辅助参数以通用海洋数据访问系统（Common Oceanographic Data Access System, CODAS）二进制格式存储。标准化（平均化）数据集以ASCII格式存储。本数据集涵盖1999年9月13日至2007年4月28日期间，由SADCP联合档案库收录的全部航次数据；该档案库由美国国家海洋和大气管理局（NOAA）与夏威夷大学E.Firing声学多普勒剖面仪实验室合作共建。上述数据由美国及全球多国科研机构共同贡献。数据集总计包含12艘科考船执行的78个航次的观测数据，总数据量约1.1吉字节。
