Abstract Here we present a collection of raw and processed temperatures from Underwater Temperature Recorders (UTRs) located off Mossel Bay, South Africa. At selected sites around Southern Africa, UTRs have been used to obtain long-term records of bottom temperatures in the nearshore environment, at depths ranging from 2m to 34m.
Methods A subsurface-mounted, Underwater Temperature Recorder (UTR) was deployed off Mossel Bay (34.1767°S; 22.1463°E), along the south coast of South Africa. The instrument measured hourly temperature readings.
