Underway sensors: Enhanced measurements from Ships of Opportunity (SOOP)

The research vessels (RV Cape Ferguson and RV Solander) of the Australian Institute of Marine Science (AIMS) routinely record along-track (underway) measurements of near-surface water temperature, salinity, chlorophyll (fluorescence) and turbidity (NTU) during scientific operations in the tropical waters of northern Australia, particularly the Great Barrier Reef (GBR). All data records include sampling time (UCT), position (Latitude, Longitude) and water depth (under keel).\n\nData are recorded at 10 second intervals. Data are measured with a Seabird SBE21 thermosalinograph and Wetlabs ECO-FLNTU chlorophyll fluorometer/turbidity sensor. The turbidity data (NTU) are currently regarded as provisional in the absence of local validation due to intermittent bubble contamination. The sampling intakes are located at depths of 1.9m (RV Cape Ferguson) and 2.8m (RV Solander).

澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）所属的“弗格森角号”（RV Cape Ferguson）与“索兰德号”（RV Solander）两艘研究船，在澳大利亚北部热带海域尤其是大堡礁（Great Barrier Reef, GBR）开展科考作业期间，会常规记录沿航迹（行进中）的近表层海水温度、盐度、叶绿素（荧光法）与浊度（NTU）数据。所有数据记录均包含采样时间（UCT）、采样位置（纬度、经度）以及龙骨下水深信息。

数据采集间隔为10秒。所用测量设备包括海鸟SBE21型走航式温盐仪（thermosalinograph）以及Wetlabs ECO-FLNTU型叶绿素荧光计/浊度传感器。鉴于存在间歇性气泡污染且尚未开展本地校准，当前浊度（NTU）数据暂视为暂定数据。采样取水口的安装深度分别为“弗格森角号”的1.9米与“索兰德号”的2.8米。
