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

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).

本数据集包含亚马孙三角洲（Amazon Delta）与塞拉利昂海隆（Sierra Leone Rise）沉积物的放射性碳分析数据。数据采集工作覆盖大西洋区域的多次科考航次，具体涵盖亚马孙三角洲航次（EN-480；2010年7月）与塞拉利昂海隆航次（EN-481；2010年8月）。沉积物采用多管采样器（multi-corer）采集，并全程冷冻保存直至分析测试。针对亚马孙三角洲与塞拉利昂海隆区域的放射性碳样品，检测工作于伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution）的海洋科学加速器质谱（National Ocean Sciences-Accelerator Mass Spectrometry, NOSAMS）实验室，采用‘踏勘法’完成。本数据集相关成果已发表于St.Laurent等人（2023）的研究中。
