Agulhas Ring SADCP of 150 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). […]

本数据集系南大西洋门户（SAGA）项目的一部分而收集。SAGA项目的总体目标是对南大西洋海洋中的北大西洋中纬度环流回流的运动进行量化与监测，尤其关注连接东西南大西洋盆地的海洋内部地带性流动。作为项目的一部分，SAGA-34.5S考察航行于2022年2月1日至3月15日，在R/V Sarmiento de Gamboa号上进行。为研究阿古拉斯环，选取了此次航行中的10个水文站，并将之划分为两条断面：一条为从第75站至第80站的纬向断面，采样南大西洋水域；另一条为从第80站至第84站的经向断面，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）获得了垂直剖面数据。
