Smith, S.B., Passino-Reader, D.R., Baumann, P.C., Nelson, S.R., and Hickey, J.T., 2018, Lake Erie Ecological Investigations 1980-2000: U.S. Geological Survey data release,


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.

The data collected as part of the LEEI evaluations have been used to ascertain whether remedial activities and contaminant reductions had been successful for AOCs on Lake Erie. In future work, the techniques established in the LEEI reevaluation can be used to monitor trends in the Lake Erie ecosystem over the long term. The LEEI dataset can serve as a foundational data source, when used in comparison to future data collections, for analyzing the long-term success or not of contaminant reductions and impacts.
