Agulhas Ring nutrients 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). […]

本数据集的收集作为全球传送带（SAGA）项目中南大西洋门户（South Atlantic Gateway）的一部分。SAGA项目的总体目标是对南大西洋洋中北大西洋中纬度环流（Atlantic Meridional Overturning Circulation）的回流进行量化与监测，尤其关注将东、西南大西洋盆地连接起来的内陆洋带状流。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R/V Sarmiento de Gamboa船上实施。为研究阿古拉斯环（Agulhas Ring），本次航次的10个水文站已被选出并划分为两条断面：一条从站75至80的带状断面，对南大西洋水域进行采样；另一条从站80至84的经向断面，对阿古拉斯环进行采样。在每个站点上，均通过导电率-温度-深度（Conductivity-Temperature-Depth，简称CTD）SBE911plus仪器获取了垂直剖面数据（https://doi.pangaea.de/10.1594/PANGAEA.972150）。
