Abstract At selected sites around Southern Africa, Underwater Temperature 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 raw temperatures from UTRs located at a depth of 18m off Karange Island North (05.1560°S 39.1672°E), along the east coast of Southern Africa, between 11 October 2007 and 27 February 2013. Note that for some deployments, two UTRs were deployed to simultaneously record bottom temperatures, and that the data that falls outside of these dates is not from the deployment.
Methods The raw data was collected using an Underwater Temperature Recorder (UTR) that was configured to sample every 60 minutes. A subsurface-mounted, Underwater Temperature Recorder (UTR) was deployed at a depth of 18m off Karange Island North (05.1560°S; 39.1672°E), along the east coast of Southern Africa. The instrument(s) measured hourly temperature(s) readings between 11 October 2007 and 27 February 2013.
