Study shows kelp can remove carbon and nitrogen pollution
January 25, 2023
The water-filtering abilities of farmed kelp could help reduce marine pollution in coastal areas, according to a new University of Alaska Fairbanks-led study.
The paper, published in the January issue of Aquaculture Journal, analyzed carbon and nitrogen levels at two mixed-species kelp farms in Southcentral and Southeast Alaska during the 2020-21 growing season. Tissue and seawater samples showed that seaweed species may have different capabilities to remove nutrients from their surroundings.
“Some seaweeds are literally like sponges — they suck and suck and never saturate,” said Sche...
