Using an automated method to create a high-resolution map of the seismic velocity below the seafloor, researchers found a large-scale gas reservoir in an area where the Earth’s upper layers are being separated. This reservoir, the first of its kind, and the potential for others like it could have implications from natural resource or environmental standpoints depending on whether the trapped gas is methane or carbon dioxide and whether it remains trapped.
