Widespread natural methane seepage observed on the U.S. Atlantic Ocean margin

According to a new study by researchers from Mississippi State University, the U.S. Geological Survey and other institutions, natural methane leakage from the seafloor is far more widespread on the U.S. Atlantic margin than previously thought. Until this research, only three seep areas had been identified beyond the edge of the continental shelf, which occurs at approximately 180 meters (590 feet) water depth between Florida and Maine on the U.S. Atlantic seafloor.Now, new results show that methane plumes identified in the water column between Cape Hatteras, North Carolina and Georges Bank, Massachusetts, are emanating from at least 570 seafloor cold seeps on the outer continental shelf and the continental slope. These areas between the coastline and the deep ocean,… »
