Sea surface salinity and temperature in the southern Atlantic Ocean from South African icebreakers, 2010-2017
10 pages, 7 figures, 4 tables We present here sea surface salinity (SSS) and temperature (SST) data collected on board the S.A. Agulhas-I and S.A. Agulhas-II research vessels, in the framework of the South African National Antarctic Programme (SANAP). Onboard Sea-Bird thermosalinographs were regular...
