Harnessing nature to restore the oceans and fix the climate crisis. The Atlantic Ocean is experiencing an unexpected symptom of climate change. Sargassum, a floating seaweed that has escaped its normal environment in the Sargasso Sea, has exploded in growth over the past decade and has been washing up in mass on Caribbean beaches. SeaFields will harvest the power of this seaweed to sequester carbon efficiently, by developing proprietary off-shore sustainable aqua-farms that control Sargassums growth, supply a value chain of diverse products to avoid CO2 emissions, and bale and sink the carbon-rich left-over biomass to the deep sea floor to achieve long-term carbon sequestration.
