Radiocarbon ages measured in multi-core sediment samples collected during the IN2017-V01 voyage of the RV Investigator
Progress Code: completed Purpose These data were collected in order to conduct multi-core sediment dating. Sediment cores were collected from the East Antarctic margin, aboard the Australian Marine National Facility R/V Investigator from January 14th to March 5th 2017 (IN2017_V01; Armand et al., 201...
