IMOS - Deep Water Moorings - Current velocity time-series

The Deep Water Moorings Facility (formerly known as the Australian Bluewater Observing System) provides the coordination of national efforts in the sustained observation of open ocean properties with particular emphasis on observations important to climate and carbon cycle studies. This collection contains time-series observations of current velocity from moorings deployed by the facility. The primary parameters are the zonal, meridional and vertical components of the current speed within different bins in the water column, the height above the instrument of each bin, the pressure (when available) and depth at the instrument. Temperature at the instrument is also usually measured. The observations were made using a range of Acoustic Doppler Current Profiler (ADCP) and Acoustic Doppler Current Meter (single point measurement) instruments. This Deep Water Moorings' dataset includes discrete locations south of Tasmania, off Queensland and Indonesia.深水锚定观测设施（Deep Water Moorings Facility）前身为澳大利亚远海观测系统（Australian Bluewater Observing System），负责统筹全国性的远洋海洋环境长期连续观测工作，重点聚焦对气候与碳循环研究具有关键价值的观测数据。本数据集收录了该设施部署的锚定观测站获取的海流流速时间序列观测资料。核心观测参数包括水柱内不同分层的海流流速纬向、经向与垂向分量，各分层相对于观测仪器的高度，仪器所处的压力（若有）以及仪器所在的水深；通常还会同步测量仪器所在位置的海水温度。本次观测采用了多款声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）与声学多普勒单点流速仪（单点测量型）。本深水锚定观测数据集的观测点位离散分布于塔斯马尼亚以南海域、昆士兰外海以及印度尼西亚附近海域。
