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 for surface ocean CO₂ observations. Each of these reflects a different layer of what TRICUSO is trying to achieve, and it is encouraging to see so many of them coming together at once.

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.
