View ArticleWhen 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...
View ArticleMore 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...
View ArticleFifty 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...
View ArticleCan 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,...

On Monday 4 May, Tillys Petit delivered the OS Division Outstanding Early Career Scientist Award Lecture at EGU 2026 in Vienna. We chatted with her about the hidden engines driving the Atlantic...
View ArticleBeyond wind speed: what really controls air-sea gas exchange?
When we think about what drives air-sea gas exchange (such as CO2), wind usually gets all the credit. Strong winds stir the surface, enhance turbulence, and speed up gas transfer. But a new study in...
View ArticleNew Unified Interface for Existing Ocean Carbonate Chemistry Data Products
Here is a great resource for anyone working on ocean carbon: Jiang et al. (2026) compiled a comprehensive synthesis of data products for ocean carbonate chemistry — all in one place for you! The paper...
View ArticleHow atmospheric circulation patterns high above the Southern Ocean influence...
The ocean surrounding Antarctica plays a crucial role in the climate system. Along parts of the Antarctic coast, very cold and salty water becomes dense enough to sink all the way to the ocean floor....

View ArticleA Record-Breaking Indian Ocean Dipole: What Happened in 2021–2022?
The Indian Ocean Dipole (IOD) is generally considered a seasonal mode of variability, developing and decaying within a single year. During 2021–2022, however, negative IOD conditions persisted for...
View ArticleHow 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...
