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.

深水锚定设施（Deep Water Moorings Facility，前身为澳大利亚蓝水观测系统）负责统筹全国范围内的开放海洋环境长期持续观测工作，重点聚焦与气候及碳循环研究密切相关的观测数据采集。本数据集包含该设施部署的锚系浮标获取的海流流速时序观测成果，核心参数包括水柱不同测层内海流流速的纬向、经向与垂向分量，各测层相对于仪器的安装高度，仪器所处位置的压力（如有可用数据）以及仪器所在水深。仪器处的海水温度通常也会同步采集。本次观测采用多类声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）与声学多普勒单点海流计（单点位测量）设备完成。本深水锚定设施数据集的观测点位离散分布于塔斯马尼亚南部、昆士兰州外海以及印度尼西亚海域。
