The paper provides a comprehensive synthesis of 68 existing ocean carbonate chemistry data products and data product sets, including cruise-based compilations, time-series datasets, gap-filled observational products, and model-based reconstructions. The authors highlight the diversity of available products, noting differences in spatial coverage, temporal resolution, methodologies, and intended scientific applications. By systematically cataloguing and comparing these datasets, the study helps researchers identify which products are most suitable for specific scientific questions related to ocean carbon cycling and ocean acidification.

We are currently seeking nominations for members of a newly established OCSIF topical subcommittee of the OCB SSC – the Ocean Carbonate System Intercomparison Forum (OCSIF). This subcommittee has its origins in the OCB OCSIF working group focused on identifying and addressing uncertainties in the seawater carbonate system and increasing measurement inter-comparability, with goals of advocating for and sparking collaborations to address these issues and providing guidance for data reporting and documentation while fostering engagement across career stages and global participation. We aim to include a range of expertise and career stages, including very early career scientists (0-4 years since PhD). Non-US applicants are encouraged to apply, as we will aim to include at least 1-2 non-US members on the subcommittee at all times. The subcommittee will include up to 15 members. We are seeking a range of expertise pertaining to the ocean carbonate system, including:
Please submit your nominations to the OCB Project Office using this nomination form by March 27, 2026 (extended). Self-nominations are welcome and encouraged!
OCB subcommittee membership terms are typically ~2-4 years, but a detailed charge and terms of reference for this new subcommittee will be established by its inaugural members. The inaugural co-chairs of this subcommittee will be Ryan Woosley (MIT) and Katelyn Schockman (U Miami/NOAA). The OCB Project Office will oversee the nomination and election process. Discussion of nominees and scoring via electronic ballot will be carried out by a small committee of subject matter experts, including Ryan and Katelyn.

This new activity has just launched and there are multiple opportunities to get involved.
→Sign up and nominate speakers for the bi-monthly webinar series. Self-nominations are encouraged.
→Apply to join the working group. Participants will be expected to prepare and analyze samples for 16S or 18S sequences and attend a synthesis meeting either in-person or virtually. Detailed protocols and workflows are expected to be made publicly available.
SOOS & APECS seek an ECR representative for the Weddell Sea & Dronning Maud Land RWG. Build your network, gain leadership experience & contribute to Southern Ocean science.
This is a great opportunity for an ECR to:
• connect with an international network of Southern Ocean researchers
• contribute to coordination of observations and data activities in the region
• gain experience in science coordination and communication
• potentially contribute to publications and working group outputs
Application deadline: 26 March 2026

Input requested for COASTAL (essentially 100km of shoreline – including inland estuarine areas) Gap Analysis Discussion Groups. This is best effort voluntary work through end of 2026. Anyone can participate, but it is being coordinated by COAST-VC for CEOS.
We invite subject matter experts to give input to the 2026 CEOS-wide Coastal Gap Analysis activity. Now is your chance to tell us your top 2 preferred Discussion Groups (out of 4) for the FIRST phase of the Gap Analysis. This first phase is expected to continue through July and we will try to honor your top selections. We hope to shuffle groups for a second phase running September – November 2026 (perhaps using different themes). We are also looking for 4 group coordinators (someone responsible for scheduling group meetings).
Completing this form is voluntary. You can revise your answers on the form. You can use the same link to submit the form entering a new email address. Information collected will ONLY be used to assign you to a subgroup and invite you to future coastal gap analysis meetings in 2026.
The initial 4 subgroups – selected following discussion at our January meetings – will meet on your own. We are looking for Leaders to schedule the meetings and sharing a progress report with COAST-VC co-leads- you can volunteer in the form. Leaders will be identified for each subgroup and they will reach out to assigned subject matter experts next week with invitations for meetings and to share foundational information to guide progress.
Please respond in this form by March 9, 12:00 UTC. Do not worry if you fail to submit the form by the deadline – you will simply be assigned to a subgroup, based upon openings – this is just a way to try to give you a voice in the assignment.
There is a strong possibility that subgroups will be shuffled midway through the year, so if you are unimpressed by your initial subgroup assignment, please contribute and just hang in there for the shuffle.
Once again we sincerely appreciate your interest and we recognize you will do your best to contribute to the Coastal Gap Analysis when and where you can. Please let me know immediately if you run into any problems with the form or you have any questions about the details outlined in the form.
Please share this with your colleagues.

The Global Ocean Biogeochemistry Array (GO-BGC) program will be hosting a Float Data workshop on August 17-21, 2026 at the University of Washington, Seattle, USA. The workshop will be a Hack-a-thon type workshop, where small groups will pursue a scientific question/objective using BGC-Argo data. This workshop will include a combination of an overview of BGC-Argo and the GO-BGC program, lectures, working (coding) with float data with your group, and a tour of the float lab at UW. Participants are expected to be familiar with how to access and utilize BGC-Argo data prior to the workshop, and to have programming experience.
To RSVP for this workshop, please fill out this form here. Note, this is not a registration, but a form to gauge interest from the community. A registration form will be sent out in the next few months.
