The Ocean Sciences (OS) Division has the major objective to provide an attractive and productive environment for scientists from Europe and all over the world to gain progress in the various ocean science disciplines and have beneficial interactions with other fields of geosciences. For that purpose, we organise with the teams of conveners the ocean science part of the program of the scientific conference that his held every year during the EGU General Assembly. We give special attention to topics cross-cutting with those of other divisions. We recognise deserving colleagues in various stages of their careers with our Award program: the division awards the Fritdjof Nansen Medal to mid or full career scientists and the Outstanding Early Career Scientists Award for researchers in the early stages of their careers. We also award prizes to outstanding student posters at every General Assembly. The division maintains very strong links with the EGU Publications Committee, and especially with the board of editors of the open access journal Ocean Science (OS). The division also collaborates with other EGU committees in the organisation of relevant topical conferences and summer schools.

How do mesoscale eddies modulate CO2 fluxes in the Southern Ocean?
Mesoscale eddies and Southern Ocean carbon sink The Southern Ocean takes up more than a quarter of the anthropogenic CO₂. Its powerful westerly winds, deep overturning circulation, and intense mixing make it a major player in Earth’s climate system. But beneath this large-scale picture lies a world of swirling, dynamic structures that constantly reshape the ocean’s physical and biogeochemical properties: mesoscale eddies. Cyclonic and anticyclonic mesoscale eddies— rotating features with spatial scales of 10–200 km— are far more than background …

Meet Arianna, the New Voice as ECS OS Representative!
Meet the new Early Career Scientist (ECS) Representative for the Ocean Sciences (OS) division: Arianna Olivelli! In this role, she is dedicated to connecting, supporting, and advocating for early career ocean researchers across Europe and beyond. We sat down with Arianna to hear about her journey, her vision for the OS ECS community, and how she is empowering the next generation of ocean scientists. 🌊 Could you briefly introduce yourself and your research background? I am a chemical oceanographer and …

A model to trace methane from the seafloor to the atmosphere
When people picture gas leaking from the seafloor, they often imagine plumes of bubbles that make up a direct path from the seabed to the sky. The reality, however, is far more complex and far more interesting. Between the seafloor and the atmosphere lies an entire ocean of physics, chemistry, and biology that controls the fate of the released gas. In fact, typically, most methane is dissolved into the seawater and only a fraction reach the surface directly as bubbles. …

Call for input: A Fisherman’s Guide to Marine Carbon Dioxide Removal
As climate change continues to reshape our oceans, science communication remains vital to the research and development of mitigation strategies. For scientists and engineers working on climate solutions, much of the conversation happens through technical papers, conference presentations, and policy memos. But invested communities outside these circles may have little access and limited time to consume such products, instead sharing information by word of mouth and social media. Closing this communication gap between scientists and communities is imperative for the …

Current issue of the EGU newsletter
In our January issue, we are choosing to reflect on the ambition and risks of science - not a new year, new you, but rather a steady determination to discover, based on our existing, deep wells of curiosity. Catarina Aydar talks about how exploration sometimes goes hand-in-hand with tragedy with the story of the first attempt of a teacher, Christa McAuliffe, to go to space, onboard the ill-fated Challenger, whilst Sabrina Minnick, shares the triumph of Jacobus Kapteyn revealing the proper motion of the stars over 100 years ago. Astrobiological chemist Silke Asche talks about her work searching for life on other planets, and András Zlinszky shares his tips for your best EGU General Assembly yet! Also don't miss our on all the upcoming webinars, newest publications, a brand new EGU open access journal, and a job vacancy in the EGU Executive office in Munich, Germany!
All this and much more, in this month's Loupe!
