Agulhas Ring SADCP of 75 kHz sampled during SAGA34.5S cruise at southeast Atlantic Ocean

The data were collected as part of the South Atlantic Gateway in the global conveyor belt (SAGA) project. The general objective of the SAGA project is to quantify and monitor the returning limb of the Atlantic Meridional Overturning Circulation in the South Atlantic Ocean, with special attention to the interior-ocean zonal flows linking the eastern and western South Atlantic basins. As part of the project, the SAGA-34.5S cruise was carried out from February 1st to March 15th, 2022, on board the R/V Sarmiento de Gamboa. For the study of an Agulhas Ring, 10 hydrographic stations of this cruise have been selected and divided into two transects: a zonal transect from stations 75 to 80, sampling the South Atlantic waters; and a meridional transect from stations 80 to 84, sampling the AR. At each station, vertical profiles have been obtained by a conductivity-temperature-depth (CTD) SBE911plus (https://doi.pangaea.de/10.1594/PANGAEA.972150). […]

该数据集的收集是作为全球传送带（SAGA）项目中的南大西洋门户（South Atlantic Gateway）研究的一部分。SAGA项目的总体目标是量化并监测南大西洋洋中北大西洋经向环流（Atlantic Meridional Overturning Circulation）的回流部分，特别关注连接东西南大西洋盆地的海洋内部纬向流。作为项目的一部分，SAGA-34.5S航次于2022年2月1日至3月15日进行，在R/V Sarmiento de Gamboa号上执行。为了研究阿古拉斯环（Agulhas Ring），本次航次的10个水文站已被选取并划分为两个剖面：一个从站75至站80的纬向剖面，用于采样南大西洋水域；以及一个从站80至站84的经向剖面，用于采样阿古拉斯环。在每个站点，通过导电率-温度-深度（Conductivity-Temperature-Depth，简称CTD）SBE911plus仪器（https://doi.pangaea.de/10.1594/PANGAEA.972150）获取了垂直剖面数据。
