Oceanographers win PM’s science prize for climate work

This year’s NZ Prime Minister’s Science Prize — worth $500,000 — has been awarded to a team of scientists working on climate-related issues at the joint Otago University and National Institute of Water and Atmospheric Research (NIWA) Centre for Chemical & Physical Oceanography. The team carried out ground-breaking research on using iron to fertilise phytoplankton growth in the southern ocean, and its effectiveness at removing carbon from the atmosphere. Team leader Professor Philip Boyd commented:

Around the world, there is a growing lobby, which includes influential people like Bill Gates, for using geo-engineering to claw back some of the carbon dioxide humans are emitting. Our research has shown that adding iron to the ocean is not going to be an effective way to do that.

You can hear Professor Boyd talking about the research in episode #6 of The Climate Show, and Professor Keith Hunter, co-director of the Centre was interviewed in Climate Show #16. “It’s the top prize in science in the country and it’s an outstanding award for science at Otago,” Hunter said today. The centre plans to spend most of its winnings on a state-of-the-art phytoplankton culture facility in Dunedin. Other members of the team were Dr Evelyn Armstrong and Dr Kim Currie of NIWA’s research unit, Associate Professor Russell Frew, Dr Sylvia Sander, and Dr Robert Strzepek (all of Otago University), Dr Cliff Law, NIWA principal scientist, and Dr Rob Murdoch, NIWA’s general manager of research.

The 2011 MacDiarmid Emerging Scientist prize was awarded to Dr Rob McKay, a world-leading glacial sedimentologist at VUW’s Antarctic Research Centre for his work using marine sedimentary records and glacial deposits to reconstruct Antarctic climate over the last 13 million years.

No Penguin Café when the ice melts

At Yale Environment 360 Fen Montaigne provides a fascinating, if disturbing, report on the findings of scientists working on the effects of sea ice retreat on the polar marine food chain. Montaigne is the author of the book Fraser’s Penguins which I reviewed earlier this year and of an earlier article at Yale Environment about the melting at the periphery of the Antarctic ice dome discussed here.

This is how it has been in the Antarctic Peninsula for a very long time:

“Marine algae, or phytoplankton, trapped in the ice and floating in the water column have burst into life as the sun catalyzes the photosynthetic process. In addition, melting freshwater from the sea ice formed a buoyant cap atop the heavier salt water, trapping the algae in the upper layer of the ocean, where it was exposed to the sun’s rays and bloomed.

“These seasonal phytoplankton blooms have fed the entire food web around Antarctica: shrimp-like krill and fish ate the phytoplankton, and virtually everything else — from Adélie penguins to humpback whales — ate the krill, which are part of the crustacean family.”
