Mercury Stable Isotope Assessment of Dragonflies and Fish Tissues across United States National Parks

This dataset details mercury (Hg) stable isotope values in dragonflies and fish tissues collected across U.S. National Parks. Dragonfly samples were collected as part of the Dragonfly Mercury Project (https://geonarrative.usgs.gov/dmp/), a citizen science project focused on using dragonfly larvae as biosentinels for Hg bioaccumulation. Fish were collected as part of separate park-wide monitoring initiatives. Biological samples were collected from 2014-2019 and composited for Hg stable isotopes measurements by the U.S. Geological Survey Contaminant Ecology Research Laboratory (CERL, Corvallis, Oregon). Measurements for Hg isotopes were performed by the U.S. Geological Survey Mercury Research Laboratory (MRL, Madison, Wisconsin).

本数据集详细记录了美国国家公园范围内采集的蜻蜓与鱼类组织中的汞（Hg）稳定同位素数值。蜻蜓样本采集自蜻蜓汞项目（Dragonfly Mercury Project，https://geonarrative.usgs.gov/dmp/），该项目是一项以蜻蜓幼虫作为汞生物累积指示物的公民科学研究计划。鱼类样本则采集自独立开展的全园区监测计划。所有生物样本于2014年至2019年间完成采集，由美国地质调查局污染生态研究实验室（U.S. Geological Survey Contaminant Ecology Research Laboratory，CERL，俄勒冈州科瓦利斯）完成复合制样，用于汞稳定同位素检测；后续的汞同位素检测工作由美国地质调查局汞研究实验室（U.S. Geological Survey Mercury Research Laboratory，MRL，威斯康星州麦迪逊）完成。
