History of bioavailable lead and iron in the Greater North Sea and Iceland during the last millennium - A bivalve sclerochronological reconstruction
We present the first annually resolved record of biologically available Pb and Fe in the Greater North Sea and Iceland during 1040-2004 AD based on shells of the long-lived marine bivalve Arctica islandica. The iron content in pre-industrial shells from the North Sea largely remained below the detec...
