Abstract At selected sites around Southern Africa, Underwater Tempearture Recorders (UTRs) have been used to obtain long-term records of bottom temperature in the nearshore environment, at depths ranging from 2m to 34m. Here we present processed daily subsurface temperatures from UTRs located at a depth of 5m off Port Nolloth (29.2524°S; 16.8671°E), along the west coast of South Africa, between 27 March 1992 and 23 July 1992.
Methods A subsurface-mounted, Hugrun Seamon Mini Underwater Temperature Recorder (UTR) was deployed at a depth of 5m off Port Nolloth (29.2524°S; 16.8671°E), along the west coast of South Africa. The instrument measured hourly temperature readings between 27 March 1992 and 23 July 1992. These hourly values were averaged to daily means. Daily values were only generated for days on which there were 75 % or more hourly readings.
