Total PCB concentrations in sediment, water, macroinvertebrates and spiders and the lower Ottawa River (Toledo, OH) between 2009-2015

Polychlorinated biphenyl (PCB) concentrations were measured in the lower Ottawa River in 2009 before dredging and after dredging in 2011, 2012, 2013, and 2015. Media collected for analysis included sediment, water, macroinvertebrates, and tetragnathid spiders at 18 stations. At each station 16 surface sediment core samples (top 15 cm) were collected and composited together with a mechanical mixer to achieve a homogeneous composite sample. Mid-depth water column samples were collected using a Van Dorn, Niskin or similar type sampler. Artificial substrate samplers (Hester Dendys) were used to collect aquatic macroinvertebrates. Riparian spiders (family Tetragnathidae) were collected from their webs by gloved hand...

Data for effects of watershed and in-stream liming on macroinvertebrate communities in acidified tributaries to an Adirondack lake

In 2012, a program was initiated using in-stream and aerial (whole-watershed) liming to improve water quality and Brook Trout (Salvelinus fontinalis) recruitment in three acidified tributaries of a high-elevation Adirondack lake in New York State. Concurrently, macroinvertebrates were sampled annually between 2013 and 2016 at 3 treated and 3 untreated reference sites to assess the effects of each liming technique on this community. Macroinvertebrate communities were monitored at 6 study sites: T16, T8A (50 m upstream of lime application point), T8 (50 m downstream of lime application point), T6 (1230 m downstream of the lime application point), and at two unlimed reference streams, T24 and T20. T24 is of similar...

Metals concentrations in insect tissues and water from the Panther Creek watershed, Idaho, September 2015

The purpose of this sampling was to collect matched aquatic insect and water samples to support metals mixture toxicity modeling. This is part of a larger study that included exposing naturally colonized insect communities to metals mixtures in long-term laboratory toxicity tests, field surveys, and modeling (Schmidt and others, 2019). The Panther Creek sampling was conducted to give a field comparison to laboratory exposures of aquatic insect communities to cobalt (Co) plus copper (Cu) mixtures, the results of which were presented as part 4 of Schmidt and others (2019). The water samples from the Panther Creek area were collected to interpret metals concentrations in the tissues of mayflies and caddisflies relative...

Reactive solute-transport simulation of pre-mining metal concentrations in mine-impacted catchments: Redwell Basin, Colorado, USA

With the increased importance of water resources in the western United States and many areas worldwide, the remediation of impacts from historical mining becomes ever more important. A possible process of making decisions about remediation for a catchment might include identification of principal sources of metals in the catchment, classification of the sources as natural or anthropogenic, and simulations to evaluate different options for removal of anthropogenic sources. The application of this process is based on understanding the pre-mining conditions in the catchment, so that remediation goals appropriately correct for the impacts of mining. A field experiment in Redwell Basin, Colorado, provided a setting to...

Lake Erie Ecological Investigations 1980-2000: Fish Community Analysis

This Fish Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the fish communities sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), fish were sampled for identification and measurement of length and weight. Identification of fish were done by the same biologists for both the 1998-2000 data and the 1986-87 historical data (Smith et al. 1994). Any fish difficult to identify were preserved in buffered formalin for later identification. If large numbers of a particular species were collected the first thirty fish were measured and weighed; remaining fish were individually measured and group weighed. All...

BLM REA MBR 2010 Areas with Low Renewable Energy Potential and Opportunities for Mitigation Fig 7

This raster is used to answer the management question (MQ) regarding areas of low potential for renewable energy development (solar, wind, geothermal) that could potentially mitigate impacts to CEs from potential energy development in the Mojave Basin and Range Ecoregion. The value indicated in the raster represents a score between 0-100, the lower values indicating areas of poor landscape condition (ecological integrity). The higher the score, better landscape conditions are expected. Areas in the middle of the spectrum likely offer areas that present opportunities for mitigation under the logic that these areas are likely to be mildly impacted by change agents and therefore present opportunities for mitigation/restoration....

Age ratios and landscape change covariates for mule deer (Odocoileus hemionus) herd units in Wyoming, USA, 1985-2019

Sagebrush ecosystems and wildlife that depend on them are under pressure from development, changing climate, as well as natural and human-caused disturbance. Mule deer (Odocoileus hemionus) are of particular concern due to population declines across many western states. We initiated a study to evaluate landscape-level changes ( disturbances, habitat treatments, development, and climate change) in Wyoming. This dataset contains age ratios (the number of juveniles to adult female mule deer) for 36 herd units in Wyoming, USA from 1985-2019. Age ratios provide a consistent metric of population demographics, including an index of recruitment (survival rate of young), which can be a sensitive metric of population change....

MODFLOW 6 models for simulating groundwater flow and a proposed remediation system in the sole-source aquifer system in southeastern Nassau County, New York

This model archive contains files for a set of groundwater flow, particle tracking, and management optimization models that simulate the area around the Navy-Northrop-Grumman contamination plume on Long Island, New York. These models were developed as in insets from the Long Island Regional “parent” Model, from which perimeter boundary conditions were inherited. In addition to input and output files for these models, this archive contains the modeling workflow python code and source data used to build the model. These materials have been included for repeatability and decision transparency.
