HOBO Water Temperature Pro Data Logger observations at Sapodilla Cayes, Belize, between July 2002 and December 2007

HOBO Water Temperature Pro Data Loggers (accuracy ± 0.2 °C and resolution 0.02 °C; http://www.onsetcomp.com) were installed at East Snake Caye within the inner lagoon reef and White Reef on the outer barrier reef. They recorded temperatures at 15-minute intervals from June 2002 to August 2005 and 10-minute intervals from October 2006 to December 2007. The logger observations, made at 3-6m depth were used as an in situ reference, to validate two satellite SST products (NOAA's CoralTemp and ESA CCI's SST version 2.1) used in coral reef monitoring. A full description of the installation process is available in Castillo KD, Lima FP. Comparison of in situ and satellite‐derived (MODIS‐Aqua/Terra) methods for assessing temperatures on coral reefs.
