Upon initial deployment, water in the tube is of mixed nutrient densities that are mostly tied to which stratum of the ocean that part of the tube is in.
As the buoy descends off a wave it causes the lower pump valve to open, infiltrating nutrient-dense deep ocean water into the bottom. As the buoy moves up the next wave, the valve closes which forces water up the tube.
Soon after deployment, the nutrient-dense water has traveled to the top of the tube where it is released, supporting growth of phytoplankton.
Our vision is to end the climate crisis, enabling Earth’s infinite wave power to slow global warming and return life to the sea.
