Blue blood on ice – How an Antarctic octopus survives the cold

[11. March 2015] 

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.

A question of light: Ocean acidification slows algae growth in the Southern Ocean

[24. February 2015] 

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.

New engines for the Research Vessel Heincke – environmentally friendly exhaust-gas aftertreatment reduces emissions

[09. February 2015] 

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.

Female sticklebacks prime their offspring to cope with climate change

[02. February 2015] 

Researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have shown that three-spined sticklebacks in the North Sea pass on information concerning their living environment to their offspring, without genetic changes. This could play an important role in the species´ ability to adapt to the effects of climate change, as AWI experts report in a recently published study in the journal Functional Ecology. Interestingly, this information transfer appears to be primarily the mother’s responsibility; in this study, the father’s temperature experiences were much less significant.
