South Atlantic Ocean profile dataset: identification of near-Antarctic profiles using unsupervised classification

<p>This dataset consists of temperature and salinity profiles taken by Argo floats (<a href="http://argo.ucsd.edu">http://argo.ucsd.edu</a>) and ship-based CTDs as recorded in the World Ocean Database (<a href="https://www.ncei.noaa.gov/products/world-ocean-database">https://www.ncei.noaa.gov/products/world-ocean-database</a>). It covers 65&deg;W to 80&deg;E in longitude, 85&deg;S to 30&deg;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.&nbsp;</p> <p>It was prepared using MITprof, which is a toolbox for Matlab:<br> <br> Gael Forget. (2017). gaelforget/MITprof: various updates and minor improvements (v1.0.1).
