Mid-Holocene variability in the marine 14C reservoir age for northern coastal Papua New Guinea

McGregor, Helen; Gagan, Michael; McCulloch, Malcolm; Hodge, Edward; Mortimer, Graham

Description

Changes in oceanic radiocarbon (14C) reservoir ages through the deglaciation and Holocene can provide important information on ocean circulation as Earth's climate warmed. Here, we present reservoir ages for the western tropical Pacific that span the mid-Holocene transition from less to more frequent El Niño events. Reservoir ages were calculated using paired U-Th and conventional 14C dating of eight individual fossil coral samples from Koil and Muschu Islands, northern coastal Papua New Guinea...[Show more]
