"We have long known that dragging heavy fishing nets—some as large as ten 747 jets—across the ocean floor destroys sea life and habitats.

Only recently, we have discovered that #BottomTrawling also unleashes plumes of carbon, which otherwise would be safely stored for millennia in the ocean floor. "

"The amount of carbon dioxide released into the ocean from bottom trawling is on the same order of magnitude as annual carbon dioxide #emissions from global aviation."

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.

"The scientists described trawling as “marine deforestation” that causes “irreparable harm” to the climate, society and wildlife.

Trawling hotspots in the East China Sea, the Baltic, the North Sea and the Greenland Sea have the largest climate emissions, the study said. Carbon released from the sea floor also causes local acidification, reducing the oceans’ capacity to absorb carbon, the study found."

Carbon released by bottom trawling ‘too big to ignore’, says study

Fishing nets churn up carbon from the sea floor, more than half of which will eventually be released into the atmosphere

""When we remove the noise of extreme short-term weather events, the data show that this warming is associated with a sustained annual decline in biomass of up to 19.8%," explains Chaikin.

"Unlike extreme short-term weather fluctuations, which can vary dramatically, this chronic warming exerts a constant negative pressure on fish populations in the Mediterranean Sea, the North Atlantic Ocean, and the Northeastern Pacific Ocean," adds Juan David González Trujillo."

Ocean warming drives a nearly 20% annual decline in fish biomass, research confirms

According to a new study by the Museo Nacional de Ciencias Naturales (MNCN-CSIC) and the National University of Colombia, chronic ocean warming is driving a nearly 20% annual decline in fish biomass. However, the researchers have found that extreme marine heat waves can sometimes mask this trend by causing temporary population increases in certain areas. The work appears in Nature Ecology & Evolution.
