  1. CATALYST ABC 20/9/12.

    Showed the terrible effects of dredging on Gladstone harbour/Curtis island sealife.
    After only a few months into the dredging sick fish and mud crabs are everywhere.
    And with another 2 years of dredging to go people are giving up hope.

    NEXT ON CATALYST.

    A PROGRAM ON THE DINOSAUR FOOTPRINTS AT JPP AND HOW WE MAY LOOSE THE UNIQUE INFORMATION THEY HOLD FOREVER.

  2. AN INTERESTING MAP.THE GREENLAND ICE CAP WILL BE MELTING OVERTIME NOW.NO ICE IN 4 TO 5 YEARS AT THE NORTH POLE WILL GREATLY ACCELERATE SEA LEVEL RISE,AND THE PLANET'S WEATHER WILL REALLY CHANGE.

    BUT THE SATELLITE MAY BE UNDERSTATING THE TRUE EXTENT OF THE MELT.

    In short, the melting effect makes it much harder to quantify the amount of ice there is and the satellite tends to see more ice than there actually is. That's why monitoring groups such as NSIDC or the university of Bremen try to compensate with weather filters or by calculating the ice extent over a number of days rather than on individual ones.

    We know, here on the ship, how misleading the satellite data can be.

    Here, possibly only 50% of the sea is covered in ice. Yet the data is telling the scientists that there is continuous ice cover at this latitude.

    That's why Julienne Stroeve, ice expert from NSIDC the folk expected to flag the record minimum ice extent record in a few days' time – has been filming the ice conditions every few hours.

    When she returns, she hopes to match her real-time observations of the ice conditions with the satellite data. She speculates that the low fog conditions we have experienced could be making it seem there is more ice than there actually is.

    The singer has recorded three new versions of the song to mark the 30th anniversary, one of them featuring children from the Mutitjulu Community, in Uluru-Kata Tjuta National Park, where Howard will be joined by indigenous artists including Archie Roach, Dan Sultan, Warren H. Williams and Stephen Pigram for a two-day concert on October 6 and 7.
    ...
    Also joining him for the weekend at Uluru will be singers Neil Murray, John Butler, Emma Donovan, Bart Willoughby, Amy Saunders and Natalie Pa'apa'a, from the Melbourne band Blue King Brown.

    Sultan and Pa'apa'a weren't born at the time Solid Rock was released.

    "It's an amazing rock song," said Sultan. "Unfortunately it's still relevant and it will be a while before it's not."

    Melbourne-based Sultan, who has a series of concerts in November called Rock For Recognition in support of the referendum, said that while he writes love songs rather than political ones, "other artists who have talked about the struggle have made it possible for indigenous artists like me to be able to go and do what I want to do in the pop world. Being a successful young indigenous man is a bit of a political statement in itself."
