Geochronology of sediment cores from the Vefsnfjord, Norway
The sedimentary environment is a repository and carrier for a variety of pollutants, and sediment transport from land to coastal areas is an important environmental process. In the present study, we use 210 Pb/ 226 Ra and 137 Cs in sediment cores to assess sediment supply rates at four sites within...

The sedimentary environment is a repository and carrier for a variety of pollutants, and sediment transport from land to coastal areas is an important environmental process. In the present study, we use 210 Pb/ 226 Ra and 137 Cs in sediment cores to assess sediment supply rates at four sites within the Vefsnfjord in Nordland county, Norway. This area was highly affected by fallout from the Chernobyl accident in 1986 and inventories of 137 Cs in the fjord are much higher than in many other Norwegian fjords.
