GPS position: 10°10.462S 143°13.584’E on WGS84 datum Depth: 2.5 m at mean tide 0.6 m at datum (Zuizin Rf) Logger located on a concrete block in a sandy area on the reef among scattered small Porites.
by Ray BerkelmansAs part of the NERP TE project 2.3 temperature loggers were deployed at 15 sites across the Torres Strait to measure ocean temperature. The loggers regularly (every 10 minutes) measure the sea water temperature and record it in their memory. Every year or so the loggers are swapped with new loggers and the recorded data is extracted and recorded in the AIMS Real Time Data Systems database as part of the Australia wide Sea Temperature Observing System.
While these loggers do not provide real time data, they provide a vital historical record of conditions across Torres Strait allowing researchers to better understand potential temperature thresholds that might cause coral bleaching. The loggers are relatively cheap and easy to deploy allowing a large number to be located across the Torres Strait. They act a silent monitors recording conditions to allow a better understanding of warm water events as well as providing information to help calibrate satellite measurements of sea temperature.
At each site loggers were placed at two depths and were located close to islands or cays to facilitate easy maintenance and replacement.
The following map shows the locations of the loggers for which data has been collected. Clicking on any of the sites on the map will create a popup with a link to the data for that site.
The following photos show the locations of the loggers and are intended to assist with locating the loggers for replacement.
Boigu
This photo shows the location of the temperature logger at Booby Island.
Shallow logger: Depth: 0.5 m at mean tide. Deep logger: Depth: 3.0m at mean tide. Both loggers are attached to a rope tied around the starboard entrance marker to the channel leading to the barge ramp. The end of the rope is tied to a block.
