Running Tide

Running Tide describes itself as a global ocean health company. With the mission of healing healing climate-damaged fisheries and of capturing carbon, they aim to sequester carbon in seaweed grown on wooden buoys, then sunk in deep water. Running Tide’s idea is to fight climate change by growing macroalgae—seaweed—on tiny ocean floats made from waste wood coated with calcium carbonate. As the carbon-rich seaweed grows, it weighs down its buoy and eventually sinks, depositing all that carbon on the seabed. This research is currently being conducted in Iceland.
