TRICUSO (Three Research Infrastructures together: Carbon Uptake Southern Ocean) is a four-year Horizon Europe research project that seeks to enhance every level of the Southern Ocean carbon observation value chain from innovating sensor technologies and expanding observation capacities via autonomous and citizen science platforms, to data products and system governance in support of the WMO Global Greenhouse Gas Watch (G3W).

An illustration of half a sun and a compass indicating south is resting at the bottom of the image. Small icons of a snowflake and flower are sprinkled around the compass, indicating winter and summer seasons happening at once on different sides of the world. TRICUSO logo is centered in the middle and white text about Newsletter goes under it, saying 'TRICUSO CURRENTS, Newsletter Volume 3 - Winter & Summer 2026'.

TRICUSO CURRENTS

TRICUSO sailed into its second year with the consortium gathering in Bergen, Norway for the project’s annual meeting, which included special guests from international and Southern Ocean organisations. With two town halls and a co-hosted session, team members shared TRICUSO’s ambitions and progress at the Ocean Sciences Meeting in Glasgow. Get the full scoops and more  in the third edition of Currents.

TRICUSO Project Video

TRICUSO’s first video showcases the beautiful scenery of the Antarctic region and focuses on early project stories. It features interviews with consortium scientists discussing the need to expand the capacity for observation in the Southern Ocean where an increase in data is needed to help address the discrepancy between data and models used for forecasting.

The TRICUSO project and members of its consortium made a healthy splash in the heavily populated waters of Ocean Sciences Meeting 2026. Held in Glasgow, Scotland, this was the first time the prestigious conference took place outside the United States, and it was a welcome setting for two town halls, a co-chaired session titled The Southern Ocean Carbon Sink: processes, observations, and change and a poster talk.

SOUTHERN OCEAN

Below 40 degrees south latitude, waves rise as high as hilltops, water chills to the lowest ocean temperature on Earth, penguin communities abound on ice shelves, and tiny Antarctic krill draw massive whales to annual feasts, while serene kelp forests shelter a diverse ecosystem of unique marine life, contributing to carbon sequestration.

Journey with us to this exciting region.
