Ben Saenz and Alicia Karspeck just got back from the Carbon to Sea Initiative 2026 Annual Convening in Halifax. We presented on C-Star (github.com/CWorthy-ocean): our open-source toolkit for mCDR siting, MRV, and efficacy assessment. Great conversations with the community pushing mCDR forward.

Congrats to Carboniferous for the recent issuance of a US EPA research permit. This is a notable milestone for the mCDR sector—progress through responsible process. The field is increasingly moving beyond early-stage enthusiasm and into the harder work of implementation. www.epa.gov/marine-prote...

Our team co-designed a workshop series in the Salish Sea with Dr. Sara Nawaz and colleagues from American University to explore how coastal communities think about ocean-based CDR in their local waters, supported by regional ocean models. Read our early reflections: www.cworthy.org/blog/regiona...

Ocean Sciences is here 🌊 [C]Worthy will be presenting posters and in sessions on ocean modeling, mCDR, and tools for mRV. If you’re attending #OSM26, come find us. Always happy to connect + talk ocean modeling.

2025 was a turning point for mCDR. Across OAE and DOC, the field moved from promise to proof: pilots advanced, first verified credits were delivered, and new standards, permits, and infrastructure took shape. We recap some of the year’s key industry milestones here: www.cworthy.org/blog/year-in...

We made a short explainer video introducing the chemistry behind Ocean Alkalinity Enhancement and Direct Ocean Capture—designed for public audiences new to mCDR. Created with Real World Visuals + American University, funded by @sloanfoundation.bsky.social. Watch now: www.cworthy.org/blog/seawate...

Configuring a regional ocean model is time-consuming, error-prone, and hard to reproduce. Our new demo shows how ROMS-Tools streamlines grid design and input file generation for ROMS-MARBL. Watch Nora Loose, PhD, walk through the workflow and its value for mCDR MRV. www.cworthy.org/blog/a-roms-...

Trust in mCDR depends on transparent, reproducible ocean models—but today they’re hard to interpret or audit. Our new blog explains how C-Star and C-Star Blueprints will help build the integrity infrastructure the field needs. Read more: www.cworthy.org/blog/buildin...

[C]Worthy has secured multi-year support from ORCA and the Patrick J. McGovern Foundation to scale open, trusted science tools for ocean-based carbon removal. We can’t scale what we can’t measure—this funding accelerates our MRV models + datasets. Full announcement: www.cworthy.org/media/cworth...
