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).

SOUTHERN OCEAN CARBON OBSERVATION
SHIPS
YACHTS
FLOATS
OBSERVATIONS
Expanding observation capacity with new platforms and methods, integrating biological observations into the EU RI landscape
TECHNOLOGY
Innovating and miniaturising sensors for citizen science and autonomous platforms and conducting long-term trials
DATA
Synthesising data to determine the optimal way measurements from new platforms can be integrated into the observing system
MAPPING
Merging new field work measurements from new platforms and running simulations to assess the current model-data mismatch
GOVERNANCE
Shaping an optimal governance structure for EU RIs to operate within the WMO Global Greenhouse Gas Watch
Passive Acoustic Sensor Capabilities
Wind drives ocean circulation, mediates the air and sea gas exchange and shapes biogeochemical processes. Yet, we have a shortage of direct wind measurements in the Southern Ocean where the most important conditions are the hardest to observe. See how TRICUSO is addressing this challenge by trialing profiling floats equipped with passive acoustic sensors.
TRICUSO at OSM26
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.
Long-term Lab and Sea Trials of the SubCtech System
The TRICUSO team at partner GEOMAR has recently achieved a project milestone of advancing data quality improvement of the SubCtech OceanPack™ through a dedicated long-term laboratory trial.
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.
