Long-term observations of hourly bottom temperatures at Nosy Iranja, Madagascar (August 2003 - October 2007)

Here we present processed hourly subsurface temperatures from Underwater Temperature Recorders (UTRs) located at a depth of 19m off Nosy Iranja, Madagascar (13.5930°S;47.7844°E), along the east coast of Southern Africa, between 06 August 2003 and 03 October 2007. 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.
