Abstract A study of the SEASAT satellite altimetry data from the Arctic has revealed gravity anomalies which may be related to the initial events of the opening of the Arctic Ocean and formation of the margins. Because of the density of the satellite altimetry data available accurate 5′ × 5′ mean gravity anomalies could be formed and analysed. An interpretation of the gravity anomalies in terms of extensional processes during margin formation has been made and it appears that the data indicates the existence of large boundinage structures in the margin. These structures are discussed in terms of their significance to the interpretation of the original rifting processes prior to and during the opening of the Arctic seafloor.
