Stable isotope ratios of hydrothermal vent alvinocaridid shrimps collected during the BICOSE 2 cruise (2018)

during the 2018 bicose 2 cruise of rv pourquoi pas ? (cambon-bonavita 2018, https://doi.org/10.17600/18000004), alvinocaridid shrimps were sampled in two deep-sea hydrothermal vent fields: snake pit and tag (mid-atlantic ridge). stable isotope ratios and elemental contents of carbon, nitrogen and sulphur of 251 samples belonging to different life stages of 4 shrimp taxa were measured. samples were identified and frozen at -80°c on board, then brought back to the laboratory for processing. they were prepared for analysis at the lep (laboratoire environnement profond, ifremer, centre de bretagne, france; https://wwz.ifremer.fr/deep_eng/). analytical measurements were performed at university of liège (belgium)’s stable isotope facility (laboratory of oceanology, stable isotope in environmental sciences and trophic ecology workgroup, http://labos.ulg.ac.be/oceanologie/recherches/isotopes-stables/). results of the analysis of the dataset for two of the shrimp species are published in: methou, p., michel, l., segonzac. m., cambon-bonavita, m.-a., pradillon, f. (2020). integrative taxonomy revisits the ontogeny and trophic niches of rimicaris vent shrimps, royal society open science.the dataset consists of two files: one containing the data itself, and one describing all used terms (measurements or metadata).

在2018年RV Pourquoi Pas ?的Bicose 2巡航活动中（Cambon-Bonavita, 2018, https://doi.org/10.17600/18000004），于中大西洋脊的蛇坑和标签两个深海热液喷口采集了阿维诺卡里虾样本。对4个虾类属不同生命阶段的251个样本进行了碳、氮和硫的稳定同位素比以及元素含量的测量。样本在船上被鉴定并冷冻于-80°C，随后带回实验室进行处理。在法国布列塔尼的深海环境实验室（LEP，IFREMER，https://wwz.ifremer.fr/deep_eng/）进行了分析准备。分析测量在比利时列日大学（Université de Liège）的稳定同位素设施（海洋学实验室，环境科学和营养生态学研究小组，http://labos.ulg.ac.be/oceanologie/recherches/isotopes-stables/）进行。关于该数据集中两种虾种分析结果的论文发表于Methou, P., Michel, L., Segonzac, M., Cambon-Bonavita, M.-A., Pradillon, F.（2020）的《综合分类学重新审视Rimicaris vent虾的发育阶段和营养生态位》一文中。该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）。
