South Atlantic Ocean profile dataset: identification of near-Antarctic profiles using unsupervised classification
This dataset consists of temperature and salinity profiles taken by Argo floats (http://argo.ucsd.edu) and ship-based CTDs as recorded in the World Ocean Database (https://www.ncei.noaa.gov/products/world-ocean-database). It covers 65°W to 80°E in longitude, 85°S to 30°S in latitude (roughly the Sou...

| Summary: | This dataset consists of temperature and salinity profiles taken by Argo floats (http://argo.ucsd.edu) and ship-based CTDs as recorded in the World Ocean Database (https://www.ncei.noaa.gov/products/world-ocean-database). It covers 65°W to 80°E in longitude, 85°S to 30°S in latitude (roughly the South Atlantic Ocean and a part of the Indian Ocean). In the vertical, it covers the top 1000m of the ocean. It was prepared using MITprof, which is a toolbox for Matlab: Gael Forget. (2017). gaelforget/MITprof: various updates and minor improvements (v1.0.1). Zenodo. https://doi.org/10.5281/zenodo.834078 This dataset should be considered the "initial" dataset that has been classified into five sub-groups using a profile classification model (PCM) built on Gaussian mixture modelling. The five-component PCM consists of these profile types: (1) subtropical Atlantic, (2) subtropical Indian, (3) circumpolar (more northern), (4) circumpolar (more southern), and (5) near-Antarctic. |
