Of particular technical interest is the way the team - led by CSIRO's Dr Ron Thresher and comprising scientists from CSIRO, the Antarctic Climate and Ecosystems Cooperative Research Centre, the Woods Hole Oceanographic Institute and the California Institute of Technology - went about its work.
Drawing on microanalysis capability at CSIRO Minerals, Dr Thresher's team applied an established (albeit continually improving) technology in a new way.
Dr Thresher started his microanalysis work in marine applications about 15 years ago in response to what he says was a dearth of historical information about the deep ocean. He could see the potential of microanalysis in helping create a picture of deep-water conditions going back centuries.
One of the objectives of Dr Thresher's deep-sea coral research was simply to help 'calibrate' existing climate change models.
"People were building all sorts of complicated models showing how water mass distribution was going to vary as a result of climate change, but there was very little information to tell us whether these models were 'real' or accurate," Dr Thresher says. "Without this sort of work, it's extremely difficult to tell whether the information we currently have relates to natural (climate) cycles, or whether it's the result of other factors."
By studying growth rings on coral collected off the south-east coast of Tasmania, the team was able to unlock details of water temperature and salinity level variations over the course of the corals' lifetime. The corals were, in a sense, living time capsules, revealing to the team secrets from centuries past.
The first thing Dr Thresher's work showed was that the corals were much longer-lived than previously thought, with some predating European settlement. He says this discovery has a bearing on the management of the coral reefs themselves: "Given its age, the coral isn't going to come back quickly if there's any damage done to it."
Perhaps more significantly, the work also shows there has been a one to one-and-a-half degree temperature change deep in the Southern Ocean over the past 400 years.
"This might not sound like much," Dr Thresher says, "but when you consider that the temperature range at these depths (about 1000 metres) is only very small (from four to six degrees), what we're looking at is a very major change."
So, what does this tell us about global warming? "Well we're still working on that," Dr Thresher says.
Dr Thresher believes that studying corals from other parts of the world will give him a much clearer picture of what's going on.

"Generally, cold-blooded animals respond to warming conditions by increasing growth rates as temperatures rise," said CSIRO marine ecologist Dr Ron Thresher, a co-author of the study with colleagues from the University of Tasmania's Institute for Marine and Antarctic Studies. "But theory and laboratory studies show that this has a limit. As temperatures get too high, we begin to see increased signs of stress, possibly eventually leading to death. We are looking at whether climate change is beginning to push fish past their physiological limits. "By examining growth across a range that species inhabit, we found evidence of both slowing growth and increased physiological stress as higher temperatures impose a higher metabolic cost on fish at the warm edge of the range," Dr Thresher said. "In this case, off northern New Zealand, ocean warming has pushed the banded morwong - which inhabits temperate reefs in waters 10-50m deep - past the point where increasing temperatures are beneficial to growth." Dr Thresher said climate change can affect species directly by influencing how their bodies function, their growth and behaviour and indirectly through environmental effects on ecosystems.

Profile : Ron Thresher Research Scientist
Ron is a marine ecologist with diverse interests, ranging from effects of climate on recruitment variability of inshore fish and crustaceans and management of invasive species to use of deep-sea corals as indicators of paleo-climate and oceanography. He got his Ph.D. in fish behavior and ecology at the University of Miami, and did post-doctoral work at Scripps Institution of Oceanography and the University of Sydney. He joined the Australian Commonwealth Scientific and Industrial Research Organization in 1983. He was the foundation head of the CSIRO Centre for Research on Introduced Marine Pests (CRIMP) and since 1997, he has lead a project aimed at developing genetic technologies for controlling introduced pest species (with a particular emphasis on carp). He has had a long interest in the use of the chemical composition of otoliths ("ear stones") in fish as possible markers of their movements and ecology, and recently broadened that interest to include analysis of the similar composition of deep-sea corals as indicators of long-term changes in ocean conditions and its implications for both understanding climate variability, the biodiversity and ecology of marine organisms and the viability of deep-sea reef communities.
