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.
9. February 2015: New engines for the Research Vessel Heincke – environmentally friendly exhaust-gas aftertreatment reduces emissions
The Research Vessel Heincke, one of the ships operated by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), recently received three new main engines. With the addition of particle filters and downstream exhaust-gas filter systems, the ship is now both more economical and environmentally friendlier.
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.
