Very Long-lived Mollusks Confirm 17th Century Ad Tephra-based Radiocarbon Reservoir Ages for North Icelandic Shelf Waters

Abstract

Marine sediment records from the north Icelandic shelf, which rely on tephrochronological age models, reveal an average ΔR (regional deviation from the modeled global surface ocean reservoir age) of approximately 150 yr for the last millennium. These tephra-based age models have not hitherto been independently verified. Here, we provide data that… (More)
