1. The atmospheric effects of Southern Ocean open-ocean polynyas onto the coastal polynyas from EC-Earth3
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : Polynyas are recurring areas of open water or thin ice within the sea ice pack, which alter the local oceanatmosphere heat and moisture exchange. They are differentiated as coastal (latent heat) or open-ocean (sensible heat) polynya according to their formation process. READ MORE

2. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

3. The implication of a changing West Antarctic Ice Sheet on future sea levels and policymaking in Sweden
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : This paper examines the future possible consequences of rising sea levels primarily due to melting Antarctic ice sheets. An objective is to research suitable methods for handling rising sea levels in Sweden. READ MORE

4. Integrated Oceans Management of Antarctic Waters: Opportunities for Marine Protected Areas in the Convergence of the Antarctic Legal Regime and the Law of the Sea
University essay from Göteborgs universitet/Juridiska institutionenAbstract : Antarctica is home to some of the last untouched places on Earth, but its marine environment is endangered because of increased ocean activities in Antarctic waters. These developments are not unique to the Antarctic seas but are a global trend in all the world’s oceans. READ MORE

5. Methane Sulphonic Acid in East Antarctic Coastal Firn and Ice Cores and Its Relationship with Chlorophyll-a and Sea Ice Extent in the Southern Ocean
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The seasonal retreat of sea ice in the austral spring and summer around Antarctica has a significant effect on phytoplankton activity, mainly due to light availability, meltwater input of dissolved iron, and surface water stratification. Phytoplankton produce dimethylsulfoniopropionate, the precursor to the climate-cooling gas dimethyl sulphide, which is ventilated to the atmosphere and oxidised to methane sulphonic acid (MSA).
