“ Ocean biomass sinking is one of several carbon removal approaches involving the ocean known as “marine carbon dioxide removal.” Other marine approaches include adding alkaline materials that react with seawater to increase the uptake of carbon dioxide, seeding oceans with iron to stimulate the growth of phytoplankton that can take up carbon dioxide, and farming seaweed to also take up carbon dioxide and sink it.”
