An Australian scientist\u00a0told the Australian Academy of Science\u2019s Earth System Outlook Conference in Canberra that Australia could be a world leader in developing marine reserves that are able to keep pace with climate change and absorb the impact of warming oceans, storms, and flood events.<\/p>\n

\u201cThe challenge we face is that a marine reserve or park usually covers a fixed geographical area \u2013 but bodies of hot ocean water, storms and flood runoff move unpredictably in space and time,\u201d said\u00a0Professor Bob Pressey of the ARC Centre of Excellence for Coral Reef Studies and James Cook University.<\/p>\n

\u201cThis means either that the reserve boundaries may have to move as things change \u2013 or else they need to located and designed carefully. If they\u2019re fixed reserves, they need to be placed away from frequent disturbances, or configured so that individual disturbance events don\u2019t affect them entirely. That way, we can include areas where sea life may take refuge to be safe from the impact.\u201d<\/p>\n

Professor Pressey said that 25 years of ocean temperature data have given scientists a much greater understanding of where coral bleaching is most severe across the Great Barrier Reef, and where corals appear to be consistently safe from the increasingly high temperatures.<\/div>\n
\n

\u201cWhile we can\u2019t easily predict when an episode of hot ocean water will move in, we can definitely see some areas which appear to avoid the harshest effects over time \u2013 whether because they are shielded in some way or cooled by cold upwelling currents.<\/p>\n

\u201cThis gives us the ability to design marine protected areas for the GBR and elsewhere that are resilient over time, no matter what changes take place.<\/p>\n

\u201cOn top of the sea temperatures, we can also potentially factor in historical data from cyclone tracks and flood plumes, or bodies of floodwater with high loads of sediment. By superimposing all these we can identify and be sure to protect those special areas of the reef which are naturally resilient and which can recharge other areas that may be damaged.\u201d<\/p>\n
