Team uncovers new marine source of carbon emissions into atmosphere
Bottom trawling is a previously unaccounted for source of atmospheric carbon emissions, scientists reveal in a study published today. As the world scrambles to slash emissions caused by fossil fuels, deforestation and other sources, the study finds bottom trawling—the act of dragging a heavy fishing net across the ocean floor and resuspending some of the carbon in the seafloor sediment—to be a significant source of atmospheric carbon pollution.
