A new source of methane for gas hydrates ice like substances found in sediment that trap methane within the crystal structure of frozen water in the Arctic Ocean. Methane produced at a mid-ocean ridge is locked up in stable, deep water gas hydrate, preventing it from possibly getting out of the seafloor. Methane produced in seafloor crust, indicate gas hydrates throughout the Arctic may be supplied by a significant portion of abiotic gas. Abiotic methane from ultraslow-spreading ridges can charge Arctic gas hydrates focused on the Arctic mid-ocean ridge system, one of two so-called ultraslow-spreading ridge regions on Earth. Abiotic methane can be generated in these ridges through a process called serpentization, which involves the reaction of seawater with hot mantle-derived rocks exposed during slow to ultraslow mid-ocean ridge spreading.
