The SACTN Web Interface

The SACTN, or South African Coastal Temperature Network (https://robert-schlegel.shinyapps.io/SACTN/), first came into existence in 2013 when a group of South African scientists determined there was a necessity for a central in situ coastal seawater temperature database. This necessity arose from the finding that satellite derived sea surface temperature (SST) values along the coast of South Africa may have warm biases as large as 6°C. These findings may be appreciated at length in the publication ‘A Coastal Seawater Temperature Dataset for Biogeographical Studies: Large Biases between In Situ and Remotely-Sensed Data Sets around the Coast of South Africa’ by Smit et al. (2013).
