Contamination of 8.2 ka cold climate records by the Storegga tsunami in the Nordic Seas
Full text linkThe 8200-year BP cooling event is reconstructed in part from sediments in the Norwegian and North Seas. Here we show that these sediments have been reworked by the Storegga tsunami – dated to the coldest decades of the 8.2 ka event. We simulate the maximum tsunami flow velocity to be 2–5 m/s on the shelf offshore western Norway and in the shallower North Sea, and up to about 1 m/s down to a water depth of 1000 m. We re-investigate sediment core MD95-2011 and found the cold-water foraminifera in the 8.2 ka layer to be re-deposited and 11,000 years of age. Oxygen isotopes of the recycled foraminifera might have led to an interpretation of a too large and dramatic climate cooling. Our simulations imply that large parts of the sea floor in the Norwegian and North Seas probably were reworked by currents during the Storegga tsunamiContamination of 8.2 ka cold climate records by the Storegga tsunami in the Nordic SeaspublishedVersio

A new approach for evaluation of remoulded shear strength in clays using the cone penetration test
Full text linkInterpretation of remoulded shear strength in soft clays based on lab and/or in-situ traditional testing can be simple and challenging, depending on the adopted approach. A new approach that uses CPTU data in the calculation of the slope parameter aq = Bq - 1/Q, together with laboratory fall cone and field vane shear tests data from 15 sites, demonstrates that when aq > 0.5, the clay under study can be considered as sensitive clay. The proposed relation is intended to be used as a first-order approximation of the remoulded shear strength that can be used as an indication of clay sensitivity. Further data and extended verification of the proposed approach are encouraged in the future for further validationA new approach for evaluation of remoulded shear strength in clays using the cone penetration testpublishedVersio
