Species occurrence data were obtained from the Atlas of Spawning and Nursery Areas of Great Lakes Fishes (Goodyear et al. 1982). The atlas contains information on all of the commercially and recreationally important species that use the tributaries, littoral and open-water areas of the Great Lakes as spawning and nursery habitats. Close to 9500 geo-referenced data records (occurrences of fish species) were imported into ArcView GIS. The 139 fish taxa reported in the Atlas had to be grouped into fewer broad categories to produce meaningful distribution maps. We chose three functional classification schemes. Jude and Pappas (1992) used Correspondence Analysis to partition fish species associated with the open...

This data set portrays the linear federally-owned land features (i.e., national parkways, wild and scenic rivers, etc.) of the Lake Michigan basin. The data set was created by extracting linear federal land features from the 1:2,000,000-scale individual State DLG files produced by the U.S. Geological Survey. These files were then merged into a single coverage. This is a revised version of the April 2000 data set.
These data show the spatial distribution of individual coastal ocean observing systems in the United States.

A bathymetric layer for Lake Erie, obtained from the Great Lakes Information Network (GLIN) at http://gis.glin.net/ogc/services.php. NOAA is engaged in a program to compile Great Lakes bathymetric data and make them readily available to the public, especially to the communities concerned with Great Lakes science, pollution, coastal erosion, response to climate changes, threats to lake ecosystems, and health of the fishing industry. This program is managed by NGDC and it relies on the cooperation of NOAA/Great Lakes Environmental Research Laboratory, NOAA/National Ocean Service, the Canadian Hydrographic Service, other agencies, and academic laboratories. Compilation of new bathymetry for the Great Lakes is...
Locations of Lake Michigan Coastal Wetlands (40 acres or more).

A medium resolution vector map of the Canadian and U.S. Great Lakes and St. Lawrence River shoreline is segmented into reaches and classified using a three tier scheme representing the geomorphic nature of the shoreline, the extent of shoreline protection, and the geomorphic nature of the nearshore subaqueous shoreline.
Point locations for collections of Michigan fish in the Lake Michigan basin.
A bathymetric layer for Lake Superior of unkown origin, obtained from the Great Lakes Information Network (GLIN) at http://gis.glin.net/ogc/services.php.

Historical cooperative station index. Cooperative stations are U.S. stations operated by local observers which generally report max/min temperatures and precipitation. National Weather Service (NWS) data are also included in this dataset. The data receive extensive automated + manual quality control. The index includes a county location cross-reference. Over 8000 stations are currently active across the country.
The concern caused by the explosive spread of the zebra mussel, (Dreissena polymorpha), within the United States resulted in passage of the Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990 (P.L. 101-646). The impact of this biofouling pest on the economy and ecological processes in the U.S. and Canada has required prompt action on a large scale to prevent further infestations and minimize ecological degradation. This map layer is a compilation of reports of confirmed zebra mussel sightings in the United States from 1988 to January 2008. It provides geographical and historical information to show distribution over time. The reports came from a variety of Federal, State, and municipal agencies, public...
