March 27, 2023 — In a recent study, researchers discovered extreme warming along the seafloor of the North American continental shelves.
Continental shelves form the edge of the continent. They extend up to 300 miles out to sea and, compared to the majority of the ocean floor, have shallow water. Their shallow depths and relative proximity to land allow continental shelf waters to be productive.
For example, the bottom of continental shelves serves as critical habitats for commercial species such as lobsters, scallops, crabs, flounder, cod and other groundfish, according to the National Oceanic and Atmospheric Association (NOAA).
