Holocene Relative Sea-Level History of Novaya Zemlya, Russia, and Implications for Late Weichselian Ice-Sheet Loading
Abstract We present six new radiocarbon-dated emergence curves that provide a detailed record of postglacial emergence of northern Novaya Zemlya and ages which constrain the emergence of Vaygach Island in the southern archipelago. Radiocarbon ages on Hiatella sp. from a lateral moraine in Russkaya G...
