Omnipresent authigenic calcite distorts Arctic radiocarbon chronology
Abstract As calcareous foraminifera precipitate their weleda skin food 75ml best price shells from the surrounding water mass, they are the basis of most marine radiocarbon chronologies and paleo-proxies.Nevertheless, post-mortem alteration of shells, especially addition of authigenic calcite, impact proxy records.In the Arctic Ocean, authigenic ca
