There's been growing research and investment in projects that use the oceans to artificially remove carbon dioxide from the atmosphere. Such techniques involve both a biological and a chemical approach.

To date, carbon removal technologies have been largely land-based, using giant air-purification machines, or planting trees to consume and store carbon. Those efforts have struggled to gain scale and acceptance. So, will a marine-based approach make any difference? It's a controversial idea and not without its difficulties.
