Thread: Is the reef really dying..?

    Re: Is the reef really dying..?

    How about this for a theory, the water gets warmer because of "global warming" doesn't the coral then just keep growing south in the right temperature, until someday, the Barrier Reef is off Sydney?

    Or if Walter Starck (I think it was lucky Phil who posted links to him years back) is correct and the bleaching is caused by prolonged periods of calm weather. Then we could in fact see the current reef see less bleaching due to the "more frequent badd weather" AND the coral blossoming further south.....

    Yes mate its all about the dollars ..a fun fact is that the salaries for Heads of Universitys in Australia now average around 1 million dollars a year (about double that of the PM) and their pay has been rising almost 10% per year the past 4-5 years....nice work if you can get it...

    and yeah there is still the odd shark out there but I think they were all under my boat last trip....

    Noel, nearly 30 years back when I used to dive a bit around Julien Rocks off Byron and the Solitary islands there was quite a lot of both hard and soft corals there..obviously not the variety and density of up here in FNQ but still pretty cool...Coral Trout off Sydney...?...still a few years away i think..

    Lovey,not just that ,but remember we have gone through an extended El nino pattern in recent years where the sea surface temperature of the tropical pacific are warmer and causes more bleaching but now as we are forecast to revert to a La nina pattern those seawater temps will presumably fall....yet it seems so much of the research showing doom and gloom is based on year to year findings in the peak of El nino rather then a longer term results which take into account variances in water temps due to global weather trends over decades or centuries.....

    Couple of pics from an overnighter late this week in some awesome weather..

    This part of the reef got pretty well bleached the past couple of summers but is bouncing back well...

    Re: Is the reef really dying..?

    With some great weather forecast this week the missus and I thought we would explore some new territory..

    We launched out of Mourylian Harbour near Innisfail on Tuesday and first stop was Pearl reef just about 30kms offshore....within an hour and a half we were bagged out on Trout and caught a whopper Gold Spot cod so we had a bit of a snorkel and headed wide to scout out some red ground...

    We also ended up with a huge pod of dolphins wanting to play with us on the ride out...

    We got a mixed bag including Red Emperor, nannigai , spangled and jobfish and had a good sleep overnight..

    We didnt want to fish in the morning as the esky had enough so we just sounded a bit more and headed back to Feather reef for another snorkel ...this reef starts only 25km's offshore and is a green zone...

    These were the worst areas of reef we have snorkelled so far..such a difference from further south of Mission Beach .....

    I guess it hasnt recovered as good as other areas possibly due to the closer proximity to land and is located directly out from the mouth of the mighty Johnstone river....

    It certainly seems to appear that the inshore fringing reefs around the islands and the very close reefs near the mainland and rivermouths seem to be the more vulnerable to damage and recovery after bleaching and natural disasters such as cyclones...I guess that stands to reason given the vast amount of silt and runoff from the Wet Tropics rainforest areas and large amount of lowland Cane and Banana farms in the region..

    Looks like a good trip well done, very jealous.

    I read a report a few years ago about testing of core samples on the reef in a substantial number of locations.
    It appears that die back is a normal part of the cycle, it also allows new forms of corals to start on areas previously dominated by a few types, adding to diversity.

    Re: Is the reef really dying..?

    The trouble is that coral does not recover quickly ...... that is the fact

    A coral bommie might be hundreds or thousands of years old .......

    I've snorkeled in a few legendary places up the Whitsundays over the past 20 + years ...... & you are kidding yourselves if the reef hasn't seen some decline . It's all cool & fine to check out some isolated reef & poo poo it ........ but the accessible reefs are a different proposition .

    While ever fishoes need to travel further & wider means that there is a problem ..... don't you think ?
