Occurrence of the Mytilus edulis complex on Nordaustlandet, Svalbard: radiocarbon ages and climatic implications
Fragments of the blue mussel (Mytilus edulis complex) are present on raised beaches in the vicinity of Langgrunnodden and Kinnvika, northwestern Nordaustlandet, Svalbard. Both of these localities are north of 80° N. New radiocarbon age determinations, together with earlier results, show that Mytilus...
