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.
Check out our project’s colourful factsheet and learn how TRICUSO is delivering a roadmap for the optimal surface Ocean pCO₂ observing system via novel sensor technology, various platforms, mapping and data synthesis.
The TRICUSO project and members of its consortium made a healthy splash in the heavily populated waters of OSM26. 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.
International Day of Women and Girls in Science supports shaping a future where science and gender equality advance together. TRICUSO marked the 2026 annual occasion by asking some of our colleagues to encourage women to consider a career in science.
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 video also introduces the project’s ambitions to innovate sensor technology and engage the support of citizen science platforms—racing yachts and tourist vessels—sailing in the Southern Ocean.
TRICUSO recently reached a significant project milestone when the inaugural Steering Committee Meeting for the Surface Ocean CO₂ Observing Network (SOCONET) took place in Bergen, Norway on 16-17 of January to establish the network’s governance structure.
Kicking off a new year, with a new trial. TRICUSO colleagues from partners Euro-Argo and CNRS-IAS in collaboration with our sister project GEORGE, have been innovating acoustic wind sensor technology on floats, building on the work from a trial they undertook late last year.
The TRICUSO consortium gathered in Bergen, Norway for the project’s first annual meeting offering a chance to review progress and achievements made in the first year, share insights and expertise, and look at the key activities needed to support TRICUSO’s objective of enhancing every level of the Southern Ocean carbon observation system.
Thanks to some good luck and dedication, Lucie Knor (GEOMAR) was able to take advantage of an exciting opportunity that involved a mad-dash to the Falkland Islands just in the nick of time to install the OceanPackTM RACE instrument on a ship of opportunity.
During the first year of TRICUSO, the Surface Ocean CO₂ Observing Network (SOCONET) experienced a significant acceleration towards the development of its international governance, coordination and communication capacity. This aligns with TRICUSO’s work package 6 objective to establish a governance structure for international surface pCO₂ observations building on ICOS experiences that incorporates stabilising SOCAT.
