Autonomous CTD

Hydrographic profiles using conductivity, temperature and depth (CTD) sondes were obtained across straits and along channels to best cover water column structure around the island. Two separate, but identical pumped Seabird 19plus CTDs with Biospherical scalar photosynthetically active radiation (PAR) and Seabird ECOtriplet fluorometer sensors, were used to collect hydrographic profiles, one standalone (autonomous) CTD and one mounted on the ship’s rosette. It is noted that the ship’s rosette also had a Seabird dissolved oxygen sensor. There were more than 200 profiles collected in total with very good coverage around the island.

利用电导率、温度和深度（CTD）测深仪获取了海峡及水道中的水文剖面数据，以最佳覆盖岛屿周围的水柱结构。在数据采集过程中，采用了两台独立且功能相同的Seabird 19plus CTD设备，配备有Biospherical标量光合有效辐射（PAR）传感器和Seabird ECOtriplet荧光计传感器。其中一台CTD独立使用（自主式），另一台安装在船舶的旋回器上。值得注意的是，船舶的旋回器还配备了Seabird溶解氧传感器。总计收集了超过200个水文剖面，对岛屿周围的水域覆盖良好。目前，数据尚未开放。如需获取数据，请联系数据管理员Janine Hunt。
