About
Ocean-based Climate Solutions, Inc. (now rebranded as The Sea Upwelling Company / Sea-Up) is a small US-based marine CDR developer, spun out of Atmocean, building wave-powered artificial upwelling pumps that bring nutrient-rich deep water to the surface to stimulate phytoplankton growth and ocean carbon sequestration. Led by Philip Kithil, the company has collaborated with GEOMAR and BIOS on open-ocean trials, with a 2024 Test-ArtUp deployment reported by GEOMAR.
