Mercury Data from the Bad River Watershed, Wisconsin, 2004 - 2018

This release includes eight data files that provide concentrations of mercury (Hg) chemical species and ancillary chemical and physical data that quantify and document aspects of the Hg cycle in stream and rivers located on tribal lands of the Bad River Band of Lake Superior Chippewa. These files were transferred to the U.S. Geological Survey by Lacey Hill Kastern, Natural Resources Department, Bad River Band of Lake Superior Chippewa in May, 2018. Files listed as Child Items in this release include data on Hg concentrations in: bald eagle feathers (Mercury Concentrations in Bald Eagle Feathers, Bad River Watershed, Wisconsin, 2014 - 2016.csv), bed sediment (Mercury Concentrations in Bed Sediment, Bad River Watershed, 2006-2015.csv), fish tissue (Mercury Concentrations in Fish Tissue, Bad River Watershed, Wisconsin, 2004-2013.csv), green frog tissue (Mercury Concentrations in Green Frog Tissue, Bad River Watershed, Wisconsin, 2012-2013.csv), litterfall (Mercury Concentrations in Litterfall, Bad River Watershed, Wisconsin, 2012-2018.csv), river otter hair (Mercury Concentrations in River Otter Hair, Bad River Watershed, Wisconsin.csv), surface waters (Mercury Concentrations in Surface Waters, Bad River Watershed, Wisconsin, 2006-2016.csv), and wild rice (Mercury Concentrations in Wild Rice, Bad River Watershed, Wisconsin, 2006.csv). Attributes describing the contents of each of these data files are provided in the .xml file that accompanies each Child Item. Note that documentation of some data sets was incomplete as received from the Natural Resources Department. Any data items in the .csv files that were not available are marked with "NA" indicating not available. This data release includes as much documentation as was provided to the U.S. Geological Survey. Neither sample collection nor Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

本数据集发布包含8个数据文件，用以记录苏必利尔湖奇珀瓦族坏河部落领地内溪流与河流中的汞（mercury, Hg）化学形态浓度，以及辅助化学与物理数据，从而量化并阐明该区域汞循环的相关特征。这些文件由苏必利尔湖奇珀瓦族坏河部落自然资源部的莱西·希尔·卡斯特恩（Lacey Hill Kastern）于2018年5月移交至美国地质调查局（U.S. Geological Survey）。本发布中列为子项的文件涵盖以下各类样品的汞浓度数据：《威斯康星州坏河流域白头海雕羽毛汞浓度，2014-2016》.csv、《坏河流域河床沉积物汞浓度，2006-2015》.csv、《威斯康星州坏河流域鱼类组织汞浓度，2004-2013》.csv、《威斯康星州坏河流域绿蛙组织汞浓度，2012-2013》.csv、《威斯康星州坏河流域凋落物汞浓度，2012-2018》.csv、《威斯康星州坏河流域河獭毛发汞浓度》.csv、《威斯康星州坏河流域地表水汞浓度，2006-2016》.csv以及《威斯康星州坏河流域野生稻米汞浓度，2006》.csv。每个子项均附带.xml格式文件，用于说明对应数据文件的各项属性。需注意的是，从自然资源部接收的部分数据集文档存在不完整的情况。.csv文件中缺失的各项数据均以"NA"（意为不可用）标注。本数据发布包含所有移交至美国地质调查局的文档资料。本数据集的样品采集与汞分析工作均非由美国地质调查局纽约水科学中心（New York Water Science Center）完成。
