Great Lakes Restoration Initiative Project 49 Fox River Basin 2016 and 2017 Data

The Fox River transports elevated loads of nitrogen and phosphorus to Lake Michigan. The increased concentration of N and P causes eutrophication of the lake, creating hypoxic zones and damaging the lake ecosystem.To decrease loading, best management practices (BMPs) have been implemented in the uplands of the basin. Little work has been done, however, to reduce nutrient concentration

Field evaluation of carbon dioxide as a fish deterrent at a water management structure along the Illinois River: Data

Resource agencies are searching for effective methods to prevent the spread of invasive Silver Carp (Hypophthalmichthys molitrix) and Bighead Carp (Hypophthalmichthys nobilis), hereafter bigheaded carps, from the Mississippi River basin into the Laurentian Great Lakes. Elevating carbon dioxide (CO2) concentrations in water within locks and other pinch points is an approach being c

Dataset for Reproductive success and contaminant associations in tree swallows (Tachnycineta bicolor) nesting in the U.S. and Binational Great Lakes' Areas of Concern

During 2010-2014, tree swallow (Tachycineta bicolor) reproductive success was monitored at 68 sites across all 5 Great Lakes, including 58 sites located within Great Lakes Areas of concern (AOCs) and 10 non-AOCs. Sample eggs were collected from tree swallow clutches and analyzed for contaminants

Annual Variation Birds as indicators of contaminants in the Great Lakes

Tachycineta bicolor eggs and nestlings were collected from sites across the Great Lakes to quantify normal annual variation in total polychlorinated biphenyl (PCBs) exposure and to validate the sample size choice in earlier work. A sample size of 5 eggs or 5 nestlings per site was adequate to quantify exposure to PCBs in tree swallows given the current exposure levels and variation.

Ethanol and sodium acetate as a preservation method to delay degradation of environmental DNA: Data

This data contains environmental DNA (eDNA) sample assay results that were collected from water samples taken from a tank housing Asian carp and placed either on ice or at room temperature. At both treatment temperatures, water samples were left untreated or were treated with an ethanol and sodium acetate solution (EtOH-NaAc).

Determine the behavior and spatial distribution of bigheaded carp in response to seismic water guns: Data

This dataset includes exported hydroacoustic data (i.e., coordinates for acoustically detected fish targets, mean target strength of detected fish).

Distribution and foraging patterns of common loons on Lake Michigan with implications for exposure to type E avian botulism: Data

Common loons staging on the Great Lakes during fall migration are at risk to episodic outbreaks of type E botulism. Information on distribution, foraging patterns, and exposure routes of loons are needed for understanding the physical and ecological factors that contribute to avian botulism outbreaks. Aerial surveys were conducted to document the spatiotemporal distribution of common

Reexamining silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp hearing: Data

Silver and bighead carp frequency detection was evaluated in response to 100 Hz to 9 kHz using auditory evoked potentials (AEPs). AEPs, consisting of measured minimum Sound Pressure Levels (SPL; dB re 1 ms-2) and Particle Acceleration Thresholds (PAT; dB re 1 ms-2).

2014 Land Cover Land Use Crane Creek, Ottawa NWR

Crane Creek is a Great Lakes Restoration Initiative-funded coastal wetland restoration project that seeks to reconnect the diked coastal marsh to Crane Creek and improve water quality and fish habitat. Vegetation sampling data and previously completed vegetation maps exist for this study area and will be used to assist in the interpretation of the 2014 imagery.

Data associated with a dye tracer study in the auxiliary lock at Lock and Dam 14 on the Mississippi River near Pleasant Valley, Iowa, June 2017

These data were collected in support of a multi-agency effort to evaluate the feasibility of using carbon dioxide to create a barrier and prevent upstream passage of invasive fish through navigational locks. The auxiliary lock at Lock and Dam 14 on the Mississippi River near Pleasant Valley, Iowa, was chosen for a field-scale trial of the carbon dioxide barrier to be conducted in 2018.

Assessing Techniques to Enhance Barrier Characteristics of High-head Navigation Dams on the Upper Illinois River: Data

The dataset is comprised of river conditions at La Grange, Peoria, Starved Rock, Marseilles, and Dresden Island Locks and Dams, along the Illinois River. Data were recorded bihourly from 1985 – 2016. For each location, pool elevation (ft), tailwater elevation (ft), head height (ft), discharge (cfs), and total gate openess.
