Agulhas Ring thermosalinograph 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). […]

该数据集的收集是南大西洋门户（SAGA）项目全球传送带（SAGA）的一部分。SAGA项目的总体目标是对南大西洋海洋中北大西洋翻转环流（AMOC）的回流进行量化与监测，特别关注连接东西南大西洋盆地的内陆洋带状流。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，在“Sarmiento de Gamboa”号研究船上实施。为研究阿古拉斯环，选取了该航次的10个水文站，并将其分为两个断面：从站点75至80的带状断面，采样南大西洋水域；以及从站点80至84的纬向断面，采样阿古拉斯环。在每个站点，通过导电率-温度-深度（CTD）SBE911plus（https://doi.pangaea.de/10.1594/PANGAEA.972150）获取了垂直剖面数据。
