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.

When the atmosphere moves the sea: Meteotsunami waves
Meteotsunamis or meteorological tsunamis are globally occurring progressive shallow water waves with a period of between 2 to 120 minutes which results from an air-sea interaction. They tend to be initiated by sudden pressure changes and wind stress from moving atmospheric systems with sources ranging from convective clouds, cyclones, squalls, thunderstorms, atmospheric gravity waves and strong mid-tropospheric winds (Vilibić and Šepić, 2017). The atmospheric pressure changes are typically only a few mb over a few tens of minutes which corresponds …

More Than a Rain Gauge: When Salt Starts Steering the Sea
Posted in: Ocean Sciences | Reviews & Perspectives | Ocean Science Jubilee Special Issue We usually think of ocean salinity as the ocean’s rain gauge. Rain, rivers, and melting ice freshen the surface; evaporation leaves it saltier. Seen from space, these changing patterns reveal how Earth’s water cycle is evolving, with wet regions generally becoming fresher and dry regions saltier as the climate warms. That familiar climate fingerprint has become increasingly clear. More than fifteen years of satellite observations, together …

Fifty years of ocean chemistry in one place: GLODAPv3 is here!
Working with marine carbonate-system observations has taught me how much effort lies behind every row of an oceanographic dataset: long hours at sea, careful sampling, laboratory analyses, calibration and quality control. A single bottle of seawater may represent only one place, one depth and one moment, but when many such samples are brought together, they can reveal how the ocean is changing. On 8 July 2026, the Global Ocean Data Analysis Project released its newest major synthesis: GLODAPv3. From individual …

Can the Ocean Explain Why Climate Models Struggle with the Indian Monsoon?
Few climate phenomena affect as many people as the Indian Summer Monsoon (ISM). Between June and September, it delivers most of the annual rainfall over the Indian subcontinent, supporting agriculture, water resources, and livelihoods for more than a billion people. Yet predicting how the monsoon will respond to climate change remains a major scientific challenge because it is shaped by complex interactions between the atmosphere and the surrounding oceans. Among these, the Indian Ocean plays a particularly important role. The …
