Radiocarbon ages of surface marine sediments at the South East Pacific (14CSS_SEP_version1)

DOI

Age constraints were evaluated to establish proxy calibrations based on marine sediments in the Southeast Pacific. This dataset includes surface sediment radiocarbon dates from the southeastern Pacific off the coast of Chile. The surface sediment samples were collected between 1962 and 2010 at span depths of 127-3267 meters and latitudes from 22°S to 44°S. The samples were obtained using multicorer (Sonne 156, Sonne 211), gravity core (Sonne 161), and a Petersen grab (USNS Eltanin). The radiocarbon analysis was measured in mixed upper thermocline planktonic foraminifera (MUTPF), Mixed shallow infaunal benthic foraminifera (MBF) and monospecific benthic foraminifera. All the foraminifera selected for the analysis were Benga-Rose unstained foraminifera. The data show that the radiocarbon age (14C) span is from modern to 10,480 years. Modern samples are samples considered younger than the calendar year 1950.
