Scientific paper

Seismic profiles in the central Barents Sea record a conspicuous structure exhibiting gross morphological and structural characteristics closely resembling those of large impact craters. This feature, named the Mjølnir structure, is 39 km in diameter and of Jurassic-Early Cretaceous age. It probably formed by the impact of an asteroid or comet, 0.7-2.5 km in diameter, into a shallow sea underlain by >5 km of sedimentary section. If the impact interpretation is correct, Mjølnir is one of the largest well-preserved craters in the errestrial record.
