Abstract:
As part of a wider paleoclimate and paleoceanographic study of Holocene-upper Pleistocene laminated sediments from the eastern equatorial Pacific and Peru continental margin, we completed 32 accelerator mass spectrometry (AMS) 14C dates from cores recovered during Ocean Drilling Program (ODP) Leg 201. Sample preparation and measurement were carried out at the ANTARES AMS facility, Australian Nuclear Science and Technology Organisation (ANSTO), in Sydney, Australia (Lawson et al., 2000, doi:10.1016/S0168-583X(00)00276-7; Fink et al., 2004, doi:10.1016/j.nimb.2004.04.025). Although the sediments are predominantly diatomaceous oozes (D'Hondt, Jørgensen, Miller, et al., 2003, doi:10.2973/odp.proc.ir.201.2003), they contain sufficient inorganic (e.g., foraminifer tests and nannofossil plates) and organic (Meister et al., 2005, doi:10.2973/odp.proc.sr.201.105.2005) carbon to allow 14C dating. These dates permitted us to reconstruct a history of sediment accumulation over the past 20 k.y., particularly on the Peru continental margin.
In this report we present 14C AMS dates and other pertinent data from cores from Sites 1227, 1228, and 1229 collected during Leg 201 at the Peru continental margin.

Comment:
Sediment depth is given in mbsf. The local marine reservoir correction used was Delta R = 238 ± 49 (Marine Reservoir Correction Database [MRCD; radiocarbon.pa.qub.ac.uk/marine/; Reimer and Reimer, 2001, supplementary material at www.calib.org] Site 108 [Taylor and Berger, 1967]) for Sites 1227-1231 and Delta R = 58 ± 47 (MRCD Site 107) for Sites 1225 and 1226.
