A team of researchers from UC Santa Barbara has proposed a novel strategy for reducing large amounts of nutrients — specifically nitrogen and phosphorous — after they have already been released into the environment. In a study appearing in the journal Marine Policy, the authors contend that seaweed’s incredible ability to draw nutrients from the water could provide an efficient and cost-effective solution. Looking at the U.S. Gulf of Mexico, the team identified over 63,000 square kilometers suitable for seaweed aquaculture.
