Atlantic sediment radiocarbon from mult-corer samples collected in the Amazon Delta and Sierra Leone Rise during R/V Endeavor cruises EN-480 and EN-481 in 2010

Abstract

These data include the sediment radiocarbon analysis for Amazon Delta and Sierra Leone Rise Sediments. These data were collected on multiple cruises in throughout the Atlantic; specifically, in the Amazon Delta (EN-480; July 2010) and Sierra Leone Rise (EN-481; August 2010). Sediments were collected using multi-corer and kept frozen until analysis. Radiocarbon was measured for the Amazon Delta and Sierra Leone Rise regions at the National Ocean Sciences-Accelerator Mass Spectrometry (NOSAMS) facility at Woods Hole Oceanographic Institute using the ‘reconnaissance’ method.

These data were published in St.Laurent, et al. (2023).
