Abstract

In August 1990 levels of Cs-137 and Sr-90 were measured in different water masses surrounding the Faroe Islands together with hydrographic parameters. In the upper layers which are of Atlantic origin the influence of the Sellafield discharge and the Chernobyl release were found to be minor; but in the colder and less saline waters north of the islands higher levels of Cs-137 and Sr-90 were found. The highest levels were those of the Arctic Intermediate Water deriving from the Greenland Sea. This water is one of the components of the overflow of cold water from the Seas north of the Greenland Scotland Ridge into the world ocean and the observations showed increased Cs-137 levels, deriving from Sellafield and/or Chernobyl, in the overflow through the Faroe Bank Channel.
