Across the Weddell Sea

[12. March 2018] 

Pteropods spend their life cycle in the water column. The organisms actively “fly” through the water, by using their feet, which transform into two wings. The Pteropods calcium shell is made of Aragonite, which makes them especially vulnerable to ocean acidification. The increasing amount of carbon dioxide in the atmosphere leads to an increased absorption of CO2 in the cold waters of the polar oceans and enhances the acidification there.

Favourable ice conditions and stable weather with southwesterly winds enabled Polarstern to go far south into the Filchner Depression and to cross directly in front of the Filchner Ice Shelf close to 44° W this week.
