A special hello to those of you who are listening to us on the web.

The Courier Mail in Brisbane carried a large item by a Senior Marine scientist (Prof Ove Hoegh-Guldberg) entering a public debate about the validity of science. The scientist was responding to a think tank report that said there was no demonstrated impact of run-off into the Great Barrier Reef. Who should we believe - the political hobbyist and his insect expert, industry funded scientist, or the body of work produced by scientists over years as their full time day job - you decide.

Cape Gantheon is the most accessable seal colony - but is still a place where you have to carry your own fridge in. A typical day in summer involves looking at the seals from a distance (through a telescope) to try and spot the small tags from a few hundred metres - easy !!

In winter it gets more fun - they catch the females and tag them - lots of hiding behind rocks, sprinting and netting them.

The study on site is to look at the population demographics on site. It is growing at about 20% per year, doubling every 4 years. This has caused concerns for the fishing industry, who see this as a threat to their industry, as the population returns to a normal level.

The true story of the mad heretic who led history's bloodiest mutiny. The spice trade ships were worth about $100 M in todays money and paid for themselves in 12 months. On the Batavia's first and last voyage, there is a plan for a mutiny hatched. On the way to execution of the plan, the ship runs aground. That caused the Mutineers to change their plan.

The plan changes to killing off everyone that is a potential threat to them taking over the rescuse ship so that they can get the cash. Of the 300 survivers, half were killed over an 8 week timeframe.

What happended when the rescuse ship arrived - get the book to find out. Dave gave it 4 seastars out of a possible five.

ATA used to stand for Alternative Technology Association. Tidal power is about trying to harness the energy from the gross changes in water level driven by the tides. Wave power is much more about capturing the energy from the small, regular rise and fall from waves.

Because of the small tidal ranges in Victoria it is not likely to catch on here, but are being considered for the large tidal range in WA.

The environmental impact is where the discussion gets interesting. The impact of the technology on the nevionment needs to be balanced against the environmental benefits of the use of the renewable energy.
