Deployed far offshore and way from coral reefs.
- 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.
