🌊 𝗙𝗶𝗳𝘁𝘆 𝘆𝗲𝗮𝗿𝘀 𝗼𝗳 𝗼𝗰𝗲𝗮𝗻 𝗰𝗵𝗲𝗺𝗶𝘀𝘁𝗿𝘆 𝗶𝗻 𝗼𝗻𝗲 𝗽𝗹𝗮𝗰𝗲: 𝗚𝗟𝗢𝗗𝗔𝗣𝘃𝟯 One seawater sample captures one place, one depth and one moment. Combined with millions of others it can help reveal how the ocean is changing. This blog post introduces GLODAPv3 and the work behind this global synthesis 👉 bit.ly/3Rj4K7K

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...

Check out our new blog post 🌊 A recent study finds that a cold bias in the northern Arabian Sea in CMIP6 models delays monsoon onset by ~1 week, weakens circulation, and reduces rainfall across India. Reducing this SST bias could improve future monsoon projections. @egu.eu bit.ly/4p8EMQB

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...

🌊🚨 New study! Beyond wind speed: what really controls air–sea gas exchange? A Baltic Sea study shows CO₂ transfer can be ~30% lower than in the open ocean due to 👉 limited fetch → smaller waves 👉 surfactants dampen turbulence Surface conditions matter! 🔗 bit.ly/4d0xx8V @egu.eu #Oceanography

Beyond 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 A...

🌬️🌊 Find out in our latest blog post how winds above Antarctica can shape the deep ocean. 🔗 bit.ly/4rU6HDB The Zonal Wave-3 atmospheric pattern influences sea ice and polynyas, helping control how much dense water sinks to form Antarctic Bottom Water. @egu.eu #OceanScience #Oceanography

How atmospheric circulation patterns high above the Southern Ocean influence the deepest layers of the global ocean

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. ...

🌊 A record-long Indian Ocean Dipole event (2021–2022): a 19-month negative phase sustained by persistent westerly wind anomalies, intensified equatorial currents, and subsurface heat storage reveals how the Indian Ocean can retain climate anomalies. 🌬️🌡️ 🔗 Blog post: blogs.egu.eu/divisions/os...

A 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 app...
