Agulhas Ring carbonate 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). […]

该数据集作为全球传送带项目（South Atlantic Gateway in the global conveyor belt，简称SAGA）的一部分而收集。SAGA项目的总体目标是量化并监测南大西洋中北大西洋中纬度环流（Atlantic Meridional Overturning Circulation）的回流部分，特别关注连接东西南大西洋盆地的内陆海区流动。作为项目的一部分，2022年2月1日至3月15日，在R/V Sarmiento de Gamboa船上进行了SAGA-34.5S航次。为了研究阿古拉斯环流（Agulhas Ring），选定了此次航次的10个水文站，并将它们分为两个断面：一个为从站75至站80的经向断面，用于采样南大西洋水域；另一个为从站80至站84的纬向断面，用于采样阿古拉斯环流。在每个站上，通过使用导电率-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。
