Southern Louisiana marsh food webs: Fatty acid data from May to October 2015

This dataset lists the fatty acid composition (in percentage for 52 fatty acids) for tissue samples collected in 2015 for the food web project within the Coastal Waters Consortium (CWC) II. It includes tissue samples of multiple consumers (fish, invertebrates, terrestrial vertebrates) as well as primary producers from salt marshes in southern Louisiana. Some of these samples were analyzed at Rutgers University (New Brunswick, NJ, USA) and others at the Ryerson University (Toronto, ON, Canada). The laboratory in which each sample was analyzed is listed in column D of file R4.x264.000-0014_2015_FA_data_sub2.xlsx, worksheet "FA_2015". This is important to note because some of the fatty acids measured by the two laboratories differ. If a fatty acid was not measured, it is indicated as “NA”. Zero values represent measurements. Information gathered at the time of collection for each sample in this dataset can be found in the subset file of GRIIDC dataset R4.x264.218:0001 (2015 Food Web Sample Key) by referencing the CWC ID Number. Additional dataset authors are Olaf Jensen, Ken Able, Joel Fodrie, Michael Polito, Jill Olin, Jessica Johnson and Jennifer Pincin.本数据集列出了2015年为沿海水域联盟（Coastal Waters Consortium, CWC）二期食物网项目采集的组织样本的脂肪酸组成（涵盖52种脂肪酸的百分比占比）。数据集包含多种消费者的组织样本，包括鱼类、无脊椎动物、陆生脊椎动物，以及路易斯安那州南部盐沼的初级生产者样本。部分样本在美国新泽西州新不伦瑞克的罗格斯大学（Rutgers University）完成分析，其余样本则在加拿大多伦多的瑞尔森大学（Ryerson University）进行检测。每个样本的分析实验室信息记录在文件R4.x264.000-0014_2015_FA_data_sub2.xlsx的"FA_2015"工作表的D列中。需特别注意的是，两家实验室所检测的脂肪酸种类存在部分差异。若某一脂肪酸未被检测，则以"NA"标注；数值为0则代表已完成该指标的检测。本数据集各样本采集时的相关背景信息，可通过参考CWC编号，在GRIIDC数据集R4.x264.218:0001（2015食物网样本关键信息）的子文件中查询获取。本数据集的其他作者包括奥拉夫·延森（Olaf Jensen）、肯·阿布尔（Ken Able）、乔尔·福德里（Joel Fodrie）、迈克尔·波利托（Michael Polito）、吉尔·奥林（Jill Olin）、杰西卡·约翰逊（Jessica Johnson）以及珍妮弗·平辛（Jennifer Pincin）。
