Heron Island

Heron Island (22.46°S, 151.93°E)

Heron Island is a 20-hectare coral cay, 65km east of Gladstone, at the southern end of the Great Barrier Reef. Half of the island is a national park, one quarter is the University of Queensland Research Station and one quarter is a resort. The island is situated on the leeward (western) side of Heron Reef, a fringing platform reef of significant biodiversity, supporting around 900 of the 1,500 fish species and 72% of the coral species found on the Great Barrier Reef.

A MAPCO2 system was deployed off Heron Island on October 10, 2009. This site has been established to monitor ocean acidification in sensitive coral reef environments through a joint effort between PMEL and the CSIRO Marine and Atmospheric Research, Australia. This site is currently operated by CSIRO.
