Division on Ocean Sciences

President: Joanna Staneva (Emailos@egu.eu)
Deputy President: Johan van der Molen (Email)
ECS Representative: Arianna Olivelli (Emailecs-os@egu.eu)

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.

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. Some dissolves into seawater and drifts with the currents, some is consumed by microbes, and only a fraction may ever …


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 …


Where Freshwater Meets the Fjord: Researching Carbon in a Changing Arctic

We sat down with Henry Henson, a PhD student at Aarhus University, whose path led from an early love of nature to studying the frontlines of climate change in the Arctic. Henry works with both Aarhus University’s Arctic Research Centre and the Greenland Climate Research Centre in Nuuk, exploring how Greenland’s coastal oceans absorb CO2 and how a warming, freshening Arctic is transforming these fragile ecosystems. His story offers a glimpse into the challenges and significance of Arctic research. 🌊What …


The Untapped Potential of Citizen Science Onboard Expedition Cruise Vessels

Scientific work can be done not only by professional scientists but also by the general public, often in collaboration with scientific institutions. At HX Expeditions, citizens have the opportunity to contribute to scientific projects on expedition cruises. Join us as we hear from Holly Stainton, the Science & Education Coordinator at MS Roald Amundsen and HX Expeditions, about her experiences aboard an expedition cruise vessel, the various citizen science projects they engage in, and their achievements. As the Science & …

Current issue of the EGU newsletter

In our November Issue we explore the interconnectedness of science and community as Bob Bateman talks about how online search patterns when earthquakes happen can improve disaster risk communication, Anjana Khatwa talks about our connections to the rocks around us in her new book, Lisa Gourdon-Grünewaldt discusses the importance of recognising and celebrating the International Day of LGBTQIA+ in STEM, Asmae Ourkiya shares the value of the new UNESCO World Soil Health Index as it connects data across countries and Eduardo Queiroz Alves gives his top 3 reasons why you should preprint your paper. Also catch up on all the upcoming dates for webinars and funding, including €10,000 to host a Geoscience Day event in your European country, and discover who the next President of EGU will be and other roles, with the results of the EGU elections. 

All this and much more, in this month's Loupe!
