Concentrations of 13'Cs ranged from below detectable or low levels in whale and fish samples to as high as 242 Bqkg in lichen. For all potential human food items, the radiocesium concentrations measured in this study were below accepted permissible levels for human con...

Pliocene palaeoceanography of the Arctic Ocean and subarctic seas.

The Pliocene is important in the geological evolution of the high northern latitudes. It marks the transition from restricted local- to extensive regional-scale glaciations on the circum-Arctic continents between 3.6 and 2.4Ma. Since the Arctic Ocean is an almost land-locked basin, tectonic activity and sea-level fluctuations controlled the geometry of ocean gateways and continental drainage sy...
