These data represent mercury (Hg), filtered total Hg (FTHg), filtered methylmercury (FMHg), particulate total Hg (PTHg), particulate methylmercury (PMHg), total mercury (THg), dissolved organic carbon (DOC) and total organic carbon (TOC) concentrations in surface water samples collected on Bad River Tribal lands. Several samples were collected at multiple locations on the Bad River and Tyler Forks Creek, and one location on Bull Gus Creek. Additionally, one sample was collected at each of four unknown locations on four Bad River tributaries and two samples at a lake of unknown location. All samples were collected during 2006 to 2016. Neither the collection of water samples nor the Hg analyses were performed by the...

This dataset includes pesticides and pesticide transformation products in 15 tributaries of the Great Lakes. Pesticides were monitored using polar organic chemical integrative samplers (POCIS) to estimate concentrations in water following standard protocols (Alvarez, 2010) in June and July 2016. POCIS extracts were analyzed for 225 chemicals (USGS National Water Quality Laboratory schedule 5437, Sandstrom and others, 2016), for which 129 chemicals also have POCIS uptake rates, allowing calculations of time-weighted mean concentration over the approximately 30 day deployment (Alvarez and others, 2008). Collectively, there were 97 chemicals detected, and time-weighted mean concentrations could be calculated for 95...

This USGS data release presents historic shorelines of Lake Superior near Odanah, Wisconsin encompassing the delta complex of the Bad River from 1852 to 2013 compiled in a Geographic Information System. The coverage of the shorelines starts approximately 8 km northeast of Ashland and extends for about 40 km to approximately 3 km east of the Bad River mouth. The shorelines were derived from land survey maps, topographic maps (USGS), and aerial photographs. The data set includes 10 shorelines for the years 1852, 1934, 1939, 1953, 1963, 1979, 1986, 1992, 1999, and 2013. Detail in the initial years of the shorelines (1852, 1934) may appear to be coarser having been hand drawn. Following 1939, all the shorelines were...

Annual litterfall samples were collected and analyzed for THg (total mercury) and MHg (methyl mercury) at a site (WI95) on Bad River tribal lands during 2012 to 2018. Litterfall was collected at a second site, WI01, during 2012 only. Litterfall was sampled in eight collectors, from which annual mass was determined. Total mercury analyses were performed on only four samples from the collectors with the lowest numbers in the sequence. A mass weighted sample based on the four THg samples was analyzed for MHg. Neither the collection of litterfall samples nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

The breast feathers of 13 bald eagles were collected at 11 locations during 2014 to 2016 along rivers and sloughs on or near to Bad River tribal lands and analyzed for total mercury (Hg) concentrations. An age (7 - 9 weeks) was indicated for only two of the eagle feather samples. The eagle feathers sampled were likely all from nestlings, but this could be confirmed for only two of the eagles. Neither the collection of feather samples nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

These data represent total mercury (Hg) concentrations and percent organic carbon in bed sediment from 51 samples collected at 44 location in streams and rivers during 2006 to 2015 within or near to Bad River Tribal lands. Reach lengths are provided when they were available, and the data set includes sieved, unsieved, and samples where sieving status was not indicated. Samples were collected by the U.S. Geological Survey, jointly by the U.S. Geological Survey and Great Lakes Indian Fish and Wildlife Commission, or unknown collection agency. Neither bed sediment sample collection nor Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

These data represent Hg concentrations in tissue of 18 green frogs from the Bad River, Wisconsin. Neither the collection of green frogs nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.
This data set is a compilation of data from two sampling efforts (2010 and 2014), focused on determining the presence and distribution of organic contaminants throughout the United States portion of the Great Lakes watershed. Water-borne contaminants were monitored in 69 tributaries of the Great Lakes using semipermeable membrane devices (SPMDs), and polar organic chemical integrative samplers (POCIS). Analyses included 185 chemicals (143 detected) including polycyclic aromatic hydrocarbons (PAHs), legacy and current-use pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ether (PBDE) and organophosphate fire retardants, pharmaceuticals, fragrances, industrial chemicals, surfactants, and others.

These data represent Hg concentrations in tissue from 104 analyses of fish samples collected at 7 sites in streams/rivers and lakes during 2004 to 2013 within or near to Bad River Tribal lands. Nine fish species are represented in this dataset. Most fish specimens were collected by the Bad River Tribe, but collection agency was not always indicated in source files.

Seven wild rice samples were collected in 2006 in or near to Bad River tribal lands and analyzed for methyl Hg. Neither the collection of wild rice samples nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

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,...
