Abstract
Carbonate crusts forming due to methane oxydation at the seepage sites on the seafloor serve as archives of the past fluid flow and methane discharges into ocean and atmosphere. Incoporation of U into the CaCO3 during precipitation offers the opportunity to date the crust formation and growth via U-Th systematics. Carbonate crust chronologies have been obtained on samples collected from the SW Barents Sea.
