ONSET DATA LOGGERS TRACK WATER TEMPERATURE AT CORAL REEF IN FIJI

HOBO® U22 data loggers to monitor potentially damaging increases in local sea temperature and determine effects on coral

BOURNE, MA, March 25, 2014 – At Naitauba, Fiji, a 2,000-acre island completely encircled by a coral reef, the Naitauba Reef Initiative is working with researchers from the University of the South Pacific (USP) School of Marine Studies to learn as much as possible about all aspects of the reef. Onset’s HOBO U22 Water Temperature Pro v2 data loggers are being used as part of that work.

In 2000 and 2002, the Naitauba reef was severely damaged by coral bleaching caused by sustained exposure to elevated sea temperatures. A 2012 survey conducted by a team from USP found that the reef is recovering nicely, with new coral colonies growing on the remnants of those that died.

“However, the return of elevated sea temperatures and damage from coral bleaching remains a potential threat,” said David Forsythe, coordinator for the Naitauba Reef Initiative. “For this reason, the capability to detect potentially damaging increases in local ocean temperatures is of fundamental importance. Onset’s HOBO water temperature data loggers will give us that capability.”

Four HOBO U22 loggers were recently deployed at a depth of 10 meters at two locations on the outer slope of the reef and at depths of 2 meters and 8 meters inside the reef to provide continuous monitoring of ocean temperatures around the reef and within its lagoon. Forsythe also has future plans to deploy additional water temperature loggers within the lagoon and inner reef areas to help understand how surrounding oceanic temperatures are transferred to the lagoon and their effect on the inner reef’s growth and development.
