11. March 2015: Blue blood on ice – How an Antarctic octopus survives the cold
An Antarctic octopus that lives in ice-cold water uses an unique strategy to transport oxygen in its blood, according to research published in Frontiers in Zoology. The study suggests that the octopus’s specialized blood pigments could help to make it more resilient to climate change than Antarctic fish and other species of octopus.
24. February 2015: A question of light: Ocean acidification slows algae growth in the Southern Ocean
In a recent study, scientists at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), demonstrate for the first time that ocean acidification could have negative impacts on diatoms in the Southern Ocean. In laboratory tests they were able to observe that under changing light conditions, diatoms grow more slowly in acidic water. In so doing, Dr Clara Hoppe and her team have overturned the widely held assumption that sinking pH values would stimulate the growth of these unicellular algae.
Around half of the carbon dioxide volume discharged into the atmosphere through exhaust pipes and chimney stacks over the past two hundred years has been absorbed by the oceans - but not without consequence.
With their research and publications scientists from the Alfred Wegener Institute substantially contributed to the IPCC report.We provide interviews, videos and fact sheets on the theme.
