This Benthic Invertebrate Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the benthic invertebrates sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), the invertebrate samples were taken from sediments remaining from the sediment analysis. Identification of the invertebrates was completed by the same invertebrate taxonomist for both the 1998-2000 evaluation and 1986-87 historical evaluation (Smith et al. 1994) for increased consistency. Oligochaetes were identified to species if possible, chironomids were identified to genus, as adult specimens are needed for specific identification, and other taxa...
This Sediment Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the sediments sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), sediment collections were a composite of at least five randomly selected samples collected from each site. Per an internal summary report, sediment samples were collected using a stainless steel Eckman dredge. Analytical methods and QA/QC were directed by the Patuxent Analytical Control Facility (PACF) of the US Fish and Wildlife Service. Per Dora Passino-Reader, the Geochemical & Environmental Research Group at Texas A&M University, College Station performed the analytical chemistry...

The Lake Erie Ecological Investigations (LEEI) dataset, housed at the Great Lakes Science Center (GLSC) was developed during a reevaluation of Lake Erie Areas of Concern (AOCs) from 1998-2000. These AOCs were recognized as such by the International Joint Commission (IJC) of the United States and Canada due to their severe water pollution problems. The dataset includes data from both the 1998-2000 reevaluation as well as data from other historical evaluations from the 1980’s to mid-1990’s for comparison where available. Data Description: Rivers and harbors of the Great Lakes have been impacted for decades by heavy industrialization, densely populated areas, and agriculture resulting in contamination, eutrophication,...
The data consists of date and time of use, activity and number of individuals visiting specific sites. This data was collected by using camera traps to monitor visitors of two mitigation areas that are being restored to riparian forests.
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...
In 1995, the Missouri River Benthic Fishes Study was initiated to provide improved information on Missouri River fish populations and how alterations might affect them. Missouri River Benthic Fishes Study (MRBFS) documented annual patterns, habitat, and water quality associations of 21 Missouri River benthic fish species based on relative abundance, including sicklefin and sturgeon chub from 1996 to 1998. Data sets include capture data and habitat characterization. The objective was to evaluate population structure and habitat use of benthic fishes along the entire mainstem Missouri River, exclusive of reservoirs.

The National Contaminant Biomonitoring Program (NCBP), which was developed and maintained by the U.S. Fish and Wildlife Service (FWS), monitored concentrations of environmental contaminants in freshwater fish over a period of about 20 years. Beginning in the 1960s as a component of the multi-agency National Pesticide Monitoring Program (NPMP) and continuing through the mid-1980s, freshwater fish were periodically collected from a national network of stations for analysis of pesticides, PCBs, and other contaminants. The NPMP/NCBP database of contaminant concentrations is the most extensive of its kind, unique in its breadth and depth with respect to environmental contaminant concentrations in fish. The data and information...

The Lake Erie Ecological Investigations (LEEI) dataset contains data collected on contaminants in sediments, benthic invertebrate populations, fish populations and abnormalities, and fish health of primarily brown bullhead in Areas of Concerns (AOCs) on Lake Erie. A subset of the larger dataset, this section specifically handles reference tables, used in database design in order to standardize often used values and to make the data file efficient, for the main tables of the LEEI dataset. The reference tables include: site.csv, site_date.csv, and species.csv.
Diet analyses were performed on juvenile lake trout (Salvelinus namaycush) captured by bottom trawl during annual USGS Great Lakes Science Center demersal fish community surveys in mid-October to mid-November 2008–2017 in Lake Huron. This dataset contains lake trout capture information (e.g., location, depth) and diet item data (taxa consumed and their associated lengths).
Image and biometric data were collected for 22 species of fish from Great Lakes Tributaries in Michigan and Ohio, and the Illinois River for the purpose of developing a fish identification classifier. Data consists of a comma delimited spreadsheet that identifies image file names and associated fish identification number, common name, species code, family name, genus, and species, date collected, river from which each fish was collected, location of sampling, fish fork length in millimeters, girth in millimeters, weight in kilograms, and personnel involved with image collection. Biometric data are saved as .csv comma delimited format and image files are saved as .png file type.

This Fish Health Evaluation dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the health of fish—primarily brown bullhead—sampled at Areas of Concern (AOCs) on Lake Erie, as measured by anomalies, tumors, biomarkers, and other heath indicators. The focus of the data in the Fish Health dataset is from the 1998-2000 study, which reevaluated fish health in comparison to data from various historical studies also in the dataset. All of the data from the 1998-2000 evaluation and the data used for comparison from historical studies are in the main FISH_HEALTH table; additional historical data, which presumably fell out of scope for comparison, is also in the OLDFISHDATA_NOTERIE...
