Long-term observations of hourly bottom temperatures at Mnemba Atoll, Zanzibar, Tanzania (September 2010 - February 2013)

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 30 September 2010 and 13 February 2013. 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.
