About
Sea-Up (The Sea Upwelling Company Inc, formerly Ocean-Based Climate Solutions) is a small Santa Fe, NM-based ocean CDR developer founded and led by Philip Kithil. The company designs and deploys wave-powered artificial upwelling pumps that bring nutrient-rich deep water to the sunlit surface to stimulate phytoplankton growth and enhance CO2 uptake, with deployments planned east of Bermuda in partnership with BIOS. The company sells upwelling pumps and fractional “Sea-Shares” rather than tons of CDR.
