MCR LTER: Coral Reef: Water Column: Offshore Water Profiles: CTD Transects

This dataset contains vertical water column profiles along transects heading offshore over the forereefs on the three sides of Moorea. These sides are designated north, southeast, and southwest. This process study intended to look for a hypothesized buoyant flow that would account for the counter-clockwise (CCW) circulation around the island. These transects were designed to look for cross-shore density gradients associated with the CCW flow. The SeaBird SBE19-Plus Profiler (CTD), outfitted with WetLabs FLNTURT-221 fluorometer, was cast at closely-spaced stations along transects oriented approximately normal to the three sides of the island. Standard CTD parameters (conductivity, temperature, and density) were used to calculate salinity, depth, and other physical quantities. No bottle samples were collected on these cruises.本数据集包含沿断面获取的垂直水柱剖面数据，这些断面朝向远海，横跨莫雷阿岛三侧的前礁区域。该岛三侧分别为北侧、东南侧与西南侧。本过程性研究旨在探寻一种假设存在的浮力流，该流系可解释岛屿周边的逆时针（CCW）环流现象。这些断面的布设目的，是寻找与该逆时针环流相关的跨岸密度梯度。本次调查采用搭载了WetLabs FLNTURT-221荧光计的SeaBird SBE19-Plus剖面仪（CTD），在大致垂直于岛屿三侧的断面上，于密间隔测站处完成布放。基于标准CTD参数（电导率、温度与密度），可计算盐度、深度及其他物理量。本次巡航未采集瓶装水样。
