Ocean Job Board
Ephemeral is a Santa Clara, CA-based MCDR company that harnesses oceanic enhanced weathering—also known as rock weathering at sea—to safely and permanently remove atmospheric carbon. By accelerating the natural weathering of silicate rocks, we introduce naturally occurring minerals into shallow ocean waters. These minerals react with CO₂ in the seawater, transforming it into stable carbonates and bicarbonates, locking away carbon securely for over 100,000 years. Along the way, this process boosts ocean alkalinity, counteracting ocean acidification and supporting healthier, thriving marine ecosystems. Join us in improving life above and below the surface. Together, we can remove CO₂ and restore our planet.
