Division on Ocean Sciences

President: Johan van der Molen (Emailos@egu.eu)
Deputy President: Joanna Staneva (Email)
ECS Representative: Coline Poppeschi (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.

Embark on an Auditory Scientific Adventure to the South Pole!

Alongside SUNNA, an oceanographic robot as daring as it is curious, you will dive into a frozen and hostile environment to uncover its secrets. Over the course of seven episodes, our hero will gather invaluable scientific data to better understand the workings of the ocean, meeting the familiar inhabitants of this environment along the way. The Southern Ocean and Argo Profiling Floats The setting for this audio adventure is the Southern Ocean, a vast ring of cold water encircling Antarctica. …


Book Review: Blue Machine by Helen Czerski

The engine that is Earth’s ocean takes sunlight and converts it into giant underwater currents and waterfalls, hauling around the ingredients for life: nutrients, oxygen and trace metals like potassium and iron, shaping our coasts and transporting heat. In her book Blue Machine – How the Ocean Shapes Our World, physicist Helen Czerski takes readers on an enlightening journey through the ocean. She explores various aspects of the ocean by blending scientific explanations with historical anecdotes, personal experiences, and fascinating …


The Jinxed Scientist: The Conference Cough Symphony

Bad things happen… but they make for the best stories. This blog is for all the jinxed souls out there who seem to attract bad luck in academia. As conferences are the perfect stage, almost predestined to showcase our most embarrassing moments, we will start right there. This blog post is for everyone who shivers at the thought of presenting on the conference stage. All the PhDs who just started and want to know the worst-case scenarios (and how they …


Sailing for Science: How Data from Sailing Races Advances Ocean Research

The Vendée Globe began on November 10th, with 44 participants embarking on the world’s toughest sailing race. This non-stop, single-handed round-the-world yacht race challenges skippers to circumnavigate the Southern Ocean. The race starts in France, traverses the North Atlantic, and heads directly into the Southern Ocean. Despite taking place during the austral summer, the conditions remain extreme, with waves reaching towering heights. In the previous race, the 2020/21 Vendée Globe, a skipper had to abandon his sinking yacht following a …
