Why are talks over an East Antarctic marine park still deadlocked? - Guest Work

Guest Work Nov 05, 2017

By Cassandra Brooks, University of Colorado. Last week, representatives from 24 countries plus the European Union met in Hobart to discuss plans for a vast marine protected area (MPA) off the coast of East Antarctica. The proposed area, spanning almost 1 million square km, is crucial for a vast array of marine life. Scientists, conservationists and governments … Read More

Antarctic ice reveals that fossil fuel extraction leaks more methane than thought - Guest Work

Guest Work Aug 24, 2017

By Hinrich Schaefer, National Institute of Water and Atmospheric The fossil fuel industry is a larger contributor to atmospheric methane levels than previously thought, according to our research which shows that natural seepage of this potent greenhouse gas from oil and gas reservoirs is more modest than had been assumed. In our research, published in Nature today, … Read More

When artists get involved in research, science benefits - Guest Work

Guest Work Aug 17, 2017

By Craig Stevens and Gabby O’Connor When artists and scientists get together, creative sparks can fly. Collaborative sci-art projects are increasingly popular and one obvious benefit is the greater visibility of the research through the artist’s work. Our project explored scientific and artistic aspects of Antarctic ice crystals. But what’s in it for the … Read More

Cows in Antarctica? How one expedition milked them for all their worth - Guest Work

Guest Work Aug 14, 2017

By Hanne E.F. Nielsen, University of Tasmania and Elizabeth Leane, University of Tasmania Domestic animals are rarely associated with Antarctica. However, before non-native species (bar humans) were excluded from the continent in the 1990s, many travelled to the far south. These animals included not only the obvious sledge dogs, but also ponies, sheep, … Read More

By Jasmine Lee, The University of Queensland; Justine Shaw, The University of Queensland, and Richard Fuller, The University of Queensland When you think of Antarctica, you probably picture vast, continuous ice sheets and glaciers, with maybe a penguin or two thrown in. Yet most Antarctic plants and animals live in the permanently ice-free areas … Read More

Volcanoes under the ice: melting Antarctic ice could fight climate change - Guest Work

Guest Work Jun 16, 2017

By Silvia Frisia, University of Newcastle  Iron is not commonly famous for its role as a micronutrient for tiny organisms dwelling in the cold waters of polar oceans. But iron feeds plankton, which in turn hold carbon dioxide in their bodies. When they die, the creatures sink to the bottom of the sea, safely storing that carbon. How exactly … Read More

The challenge and importance of predicting sea-level rise - Guest Work

Guest Work Feb 06, 2017

By Prof Tim Naish, Director of the Antarctic Research Centre, Victoria University Wellington By the end of the century it is predicted that rising sea-level will directly impact more than 200 million people around the world. The damage to property and infrastructure, groundwater, and the prospect of widespread displacement of people will indirectly affect every one of us on this … Read More

Scientist keeps cool head on the ice - Field Work

Guest Work Jan 10, 2017

NIWA marine physicist Dr Natalie Robinson. Top of Natalie Robinson’s to-do list right now is to work out exactly what she’s brought back from Antarctica. The NIWA marine physicist has recently spent five weeks on the ice leading a team of researchers trying to solve one of the great conundrums facing scientists researching climate change: why has Antarctic sea ice … Read More
