Atlantic sediment polycyclic aromatic hydrocarbon (PAH) concentrations from samples collected using a multi-corer and box corer from multiple cruises throughout the Atlantic between 1994 and 2010

These data include sediment polycyclic aromatic hydrocarbon (PAH) concentrations. These data were collected on multiple cruises in throughout the Atlantic; specifically, in the Amazon Delta (EN-480; July 2010), Sierra Leone Rise (EN-481; August 2010), Niger Delta (GeoB 4901, GeoB 4903, GeoB 4904, GeoB 4905, GeoB 4907, and GeoB 4908; February/March 1998), Senegal Delta (GeoB 9501; April/May 2003), and Northwest Argentina Basin (GeoB 2814; July/August 1994). Sediments were collected using multi-corer and box corer samples and kept frozen until analysis.

Polycyclic aromatic hydrocarbon concentrations were determined by gas chromatography mass spectrometry. A total of 24 PAH analytes were quantified using ChemStation software. These data help better constrain pyrogenic carbon sources and PAH accumulation rates into Atlantic sediments.

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

本数据集包含沉积物中多环芳烃（polycyclic aromatic hydrocarbon, PAH）的浓度数据。样品采集自大西洋全域的多次科考航次，具体覆盖区域包括亚马逊三角洲（EN-480航次，2010年7月）、塞拉利昂海隆（EN-481航次，2010年8月）、尼日尔三角洲（GeoB 4901、GeoB 4903、GeoB 4904、GeoB 4905、GeoB 4907及GeoB 4908，1998年2/3月）、塞内加尔三角洲（GeoB 9501，2003年4/5月）以及阿根廷西北盆地（GeoB 2814，1994年7/8月）。沉积物样品采用多管取样器与箱式取样器采集，并全程冷冻保存直至实验室分析。多环芳烃浓度通过气相色谱-质谱联用法测定，共使用ChemStation软件对24种多环芳烃目标分析物进行定量。本数据集可用于更精准地限定大西洋沉积物中的热解碳源与多环芳烃沉积速率。本数据集相关成果发表于St.Laurent等人（2023）的研究中。
