Stable isotope ratios of C and N in cold seep fauna from the Gulf of Guinea collected during the WACS cruise (2011)

during the 2011 wacs cruise of rv pourquoi pas ? (olu 2011, https://doi.org/10.17600/11030010), biomass-dominant fauna was sampled in several cold seep sites of the gulf of guinea (regab, guinness, baboon and worm hole pockmarks) as well as in the congo river deep-sea fan (lobes a, c and d). stable isotope ratios of carbon and nitrogen of 406 samples belonging to >20 taxa and sediments were measured. samples were prepared for analysis at the umr6197 beep (biologie et ecologie des ecosystèmes marins profonds, ifremer, centre de bretagne, france; https://www.umr-beep.fr/). analytical measurements were performed at geotop’s light stable isotope geochemistry laboratory (uqam, montreal, canada).this data was used for the analyses underlying the paper "environmental parameters and biotic interactions influence food web structure in deep-sea cold seeps from the gulf of guinea", by loïc n. michel, marie portail, dominique a. cowart, pen-yuan hsing, lucie pastor, karine olu & jozée sarrazin.the dataset consists of two files: one containing the data itself, and one describing all used terms (measurements or metadata).

在2011年RV Pourquoi Pas?的WACS巡航期间（Olu 2011，https://doi.org/10.17600/11030010），于几内亚湾多个冷泉地点（包括Regab、Guinness、Baboon和Worm Hole Pockmarks）以及刚果河深海扇（Lobes A、C和D）采集了生物量占主导地位的生物群落样本。对属于超过20个分类群和沉积物的406个样本的碳和氮的稳定同位素比值进行了测量。样本在法国布列塔尼中心（IFREMER）的UMR6197 BEEP（深海生态系统生物学与生态学，https://www.umr-beep.fr/）进行了分析准备。分析测量在Geotop的光稳定同位素地球化学实验室（加拿大魁北克省蒙特利尔，UQAM）进行。这些数据被用于支撑论文《环境参数和生物相互作用影响几内亚湾深海冷泉的食物网结构》的分析，该论文由Loïc N. Michel、Marie Portail、Dominique A. Cowart、Pen-Yuan Hsing、Lucie Pastor、Karine Olu和Jozée Sarrazin所著。数据集包含两个文件：一个包含实际数据，另一个描述了所有使用的术语（测量或元数据）。
