The European Ocean Carbon Summit is a campaign driven by a coalition of Horizon Europe projects focussed on ocean carbon to jointly summarise the aims and achievements of this EU investment portfolio and make recommendations for future funding actions; findings will be presented at an...
Down Under in the Southern Ocean, the TRICUSO team has achieved another great success with the implementation of a surface pCO₂ sensor – an underway system on the MV Pharos, enabling crucial measurements of the surface ocean’s uptake of carbon.
To improve the accuracy of the ocean carbon sink estimates, racing yachts and fishing vessels are being equipped with underway sensors able to measure CO₂. Milestone 9 describes the diagnosis of an optimal sailing yacht equipment fitting strategy and the studies it is based on.
The 2026 release of the Surface Ocean CO₂ Atlas (SOCAT) marks a landmark moment for ocean carbon science and for the TRICUSO project. With 44 million quality-controlled measurements now publicly available, SOCAT v2026 offers an unprecedented window into the health of the ocean carbon sink.
For the first time, a new approach to characterise surface ocean pCO₂ variability using observations from multiple Research Infrastructures, which disentangles the anthropogenic and circulation-driven contributions to observed pCO₂ changes, has been successfully validated at reference ocean time-series stations and extended to the Southern Ocean.
Partner NOC’s lab-on-chip technology miniaturises analytical laboratory methods into compact autonomous sensors. For this milestone, the focus has been on the TADIC sensor, which combines two carbonate-system measurements within a single autonomous lab-on-chip platform…
This has been a productive stretch for the project, and June looks set to be a highlight, with milestones arriving across sensor integration on autonomous platforms, observing system design, engagement with the racing yacht industry, and the first steps toward building an international governance structure...
A new observation-based estimate of the Southern Ocean carbon sink, south of 30°S, has been achieved by using machine learning to combine traditional ship-based measurements from SOCATv2025 with year-round data from autonomous Biogeochemical-Argo (BGC-Argo) floats.
The TRICUSO team at partner GEOMAR has achieved a project milestone of advancing data quality improvement of the SubCtech OceanPack™ through a dedicated long-term laboratory trial.
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...
