Abstract Here we present a collection of raw and processed temperatures from Underwater Temperature Recorders (UTRs) located off Port St. Johns. 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 Subsurface-mounted, Underwater Temperature Recorder(s) (UTR) were deployed off Port St. Johns, South Africa, along the south coast of Southern Africa. The instrument(s) measured half-hourly temperature(s) readings.
