The Great Barrier Reef Marine Park Authority, in conjunction with the
Australian Institute of Marine Science and NOAA, are once again closely
monitoring conditions on the Great Barrier Reef as summer progresses.
Below is a summary of the latest coral bleaching status report. The
full status report can be found on the GBRMPA web site:
GBR Coral Bleaching Status Update - 14 January 2002
The news continues to be good in terms of coral bleaching risk for the
Great Barrier Reef (GBR) this summer. Weather conditions remain
relatively mild, with good cloud cover and persistent winds keeping sea
temperatures at or below seasonal averages, despite El Nino conditions
over much of eastern Australia. No significant coral bleaching has been
reported to date from the Reef, and bleaching thresholds have not been
reached at any key monitoring sites.
This time last year, sea temperatures were 2-4 degrees C above current
temperatures, resulting in the worst coral bleaching event ever
recorded for the GBR. While the milder conditions this year are cause
of some optimism, hot conditions leading to widespread coral bleaching
in 1998 did not develop until the end of January. This suggests that
there is still some potential for a coral bleaching event on the GBR in
the months ahead, although the risk of an event as severe as last
summer is now substantially reduced. A full report of the 2002
bleaching event can also be found on the GBRMPA web site:
The GBRMPA, in conjunction with AIMS and NOAA, will continue to closely
monitor and report on conditions on the Reef throughout summer.
The GBRMPA welcomes any reports of coral bleaching. If you regularly
visit a reef site, or you have seen bleaching on the reef, we would be
grateful for your input to our Community Bleaching Assessment Program.
