For the first time since the 1970s, a huge hole opened in the winter sea ice cover in the Southern Ocean: the Weddell Polynya. We describe this phenomenon, hypothesise potential atmospheric causes for its opening that our PhD student, Martin Mohrmann, is currently working on (dis)proving, and show biogeochemical timeseries collected by the SOCCOM float that accidentally ended up in the polynya.
