Killer Whale Biopsy Genetic and Chemical Data from Southern Alaska, 1994 to 2016, Gulf Watch Alaska Pelagic Component

These data are part of the Gulf Watch Alaska (GWA), Pelagic Component of the Exxon Valdez Oil Spill Trustee Council, project numbers 12120114-M, 13120114-M, 14120114-M, 15120114-M and 16120114-M. Gulf Watch Alaska is the long-term ecosystem monitoring program of the Exxon Valdez Oil Spill Trustee Council for the marine ecosystem affected by the 1989 oil spill. This dataset is seven comma-separated values (csv) files containing chemical and lipid concentration measurements for killer whale tissue samples collected between 1998 and 2014 in Prince William Sound. Biopsy samples were obtained from individually identified whales. Samples (skin and blubber) were stored as wet frozen materials at -80° C until analyzed for their chemical tracers at the Northwest Fisheries Science Center (NWFSC). Specifically, each biopsy sample was analyzed for their skin carbon and nitrogen stable isotope (SI) ratios, blubber fatty acids (FAs), and persistent organic pollutants (POPs).本数据集隶属于埃克森·瓦尔迪兹溢油赔偿托管委员会（Exxon Valdez Oil Spill Trustee Council）下属的阿拉斯加海湾观察（Gulf Watch Alaska, GWA）远洋组分项目，涉及项目编号12120114-M、13120114-M、14120114-M、15120114-M及16120114-M。阿拉斯加海湾观察计划是该托管委员会针对1989年溢油事故影响海域开展的长期生态系统监测项目。本数据集包含7个逗号分隔值（comma-separated values, CSV）文件，收录了1998年至2014年间在威廉王子湾采集的虎鲸组织样本的化学物质与脂质浓度检测数据。活检样本均取自经个体识别的虎鲸，采集的样本（皮肤与鲸脂）以湿冻状态保存于-80℃环境中，直至送至美国西北渔业科学中心（Northwest Fisheries Science Center, NWFSC）开展化学示踪物检测分析。具体而言，每份活检样本均针对其皮肤的碳、氮稳定同位素（Stable Isotope, SI）比值、鲸脂脂肪酸（Fatty Acids, FAs）以及持久性有机污染物（Persistent Organic Pollutants, POPs）进行了检测分析。
