Long-term observations of hourly bottom temperatures at Mnemba Atoll, Zanzibar, Tanzania (February 2013 - March 2017)

Here we present processed hourly subsurface temperatures from Underwater Temperature Recorders (UTRs) located at a depth of 19m off Mnemba Atoll, Zanzibar, Tanzania (05.8409°S 39.3957°E), along the east coast of Southern Africa, between 13 February 2013 and 26 March 2017. At selected sites around Southern 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.
