Long-term observations of hourly bottom temperatures at Port Alfred ( March 1999 - August 1999)

Here we present processed hourly subsurface temperatures from Underwater Temperature Recorders (UTRs) located at a depth of 4m off Port Alfred (33.6027°S; 26.8999°E), along the east coast of South Africa, between 23 March 1999 and 17 August 1999. At selected sites around South Africa, UTRs have been used to obtain long-term records of bottom temperature in the nearshore environment, at depths ranging from 2m to 34m. Note that for some deployments, two UTRs were deployed to simultaneously record bottom temperatures.
