Title: Commercial Waterway Network, Great Lakes Region 2019
Contributors:- Polygon data
- 2019
Summary: The National Waterway Network is comprised of a link database and a node database. Links are line strings, which consist of beginning and end points (nodes) with intermediate vertices (shape points). Links represent either actual shipping lanes (i.e., channels, Intracoastal Waterways, sealanes, rivers) or serve as representative paths in open water (where no defined shipping paths exist). Nodes may represent physical entities such as river confluence's, ports/facilities, and intermodal terminals, USACE nodes, or may be inserted for analytical purposes (i.e., to facilitate routing). The NWN databases were developed by Oak Ridge National Laboratory (ORNL) and Vanderbilt University, with input from the National Waterway GIS Design Committee (NWGISDC). The NWGISDC contains members from several agencies, including the U.S. Army Corps of Engineers (USACE), USDOT Bureau of Transportation Statistics (BTS), Volpe National Transportation Systems Center (VNTSC), Maritime Administration (MARAD), Military Traffic Management Command (MTMC), Tennessee Valley Authority (TVA), U.S. Environmental Protection Agency (EPA), U.S. Bureau of Census, U.S. Coast Guard, and the Federal Railroad Administration (FRA). Several data sources were used to create the network. Therefore, network links vary in scale. The majority of the inland links are at 1:100,000 scale(derived from 1:100,000 scale Digital Line Graph files). Off-shore links were derived from variable scale NOAA Navigational Charts. Therefore, the off-shore links vary in scale, with larger scale NOAA charts used in harbor/bay/port areas, and smaller scale NOAA charts used in open waters. All links in the USACE (non geo-coded) Waterway Link Network are represented in the NWN. The USACE network was used as a base for the NWN; 'USACE links' form a contiguous subset within the NWN, and can be extracted through queries on the 'link number' (linknum) field in the link database (where linknum<1000000). Additional (non- USACE) links and nodes were added to the USACE network to more realistically represent shipping patterns. Approximately 200 USACE ports are geo-coded in the node database, including the top 150 ports. ORNL initially developed databases for the inland waterways; Vanderbilt constructed databases for the off-shore waterways. ORNL then merged the inland and off-shore databases to form a continuous national network. Vanderbilt revised the inland waterway network through use of USGS Digital Line Graph (DLG) files. Vanderbilt, ORNL, and the U.S. Army Corps of Engineers Waterborne Commerce Statistics Center (WCSC) are continuously enhancing and performing validation tasks to improve the accuracy of the NWN.

Title: Fish Spawning Locations, Great Lakes Region 2019
Contributors:- Point data
- 2019
Summary: 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 water of each of the five Great Lakes and nine coastal wetlands. Three species complexes were suggested: a Great Lakes taxocene; a transitional taxocene, which utilized open water, near-shore, and wetlands; and a wetland taxocene. We chose this as one of the classification schemes because we are particularly interested in identifying the distribution pattern of fish with coastal wetlands; for clarity sake, we have renamed these taxocenes coastal, intermediate and open-water, respectively. For comparison, we also used Coker et al.??s (2001) classification based on temperature preferenda (5 classes) and Balon??s (1975) reproductive guild classification (32 guilds).

Title: Cold Water Threat, Great Lakes Region 2017
Contributors:- Polygon data
- 2017
Summary: Cold Water Resource Threat: A measure of vulnerability of Great Lakes watersheds to thermal loading, based on the most influential factors that shape thermal conditions: mean annual air temperature, groundwater discharge potential, surface water extent, and riparian forest cover (weighted and used to develop an environmental index of aquatic resource sensitivity or vulnerability to thermal loadings).The product of the thermal vulnerability and the miles of coldwater streams in a given watershed (mean July temperature of 75 received a score of 1.00. The scale then breaks down as follows: 0.00 = High Threat, 0.33 = Moderate Threat, 0.66 = Low Threat, 1.00 = Extremely Low Threat

Title: Bird Survey Grid, Great Lakes Region 2015
Contributors:- Polygon data
- 2015
Summary: This dataset was developed as part of a two-phase project by the Great Lakes Commission and collaborators, entitled Monitoring and Mapping Avian Resources Over Selected Areas of the Great Lakes and Outreach to Support Related Resource Management (2012-2014). This project was funded by the US Fish and Wildlife Service. Visual aerial surveys for pelagic waterbirds were conducted over two fall and two spring migration seasons, with several additional surveys occurring during the winter months. Surveyors included: Biodiversity Research Institute (eastern Lake Erie, 2013-2014); Michigan Department of Natural Resources and Michigan State University (Lake St. Clair, western Lake Erie, and Detroit River, 2012-2014); Michigan Natural Features Inventory (Lake Huron, 2012-2014); US Geological Survey (Lake Michigan, 2012-2014); and the Western Great Lakes Bird and Bat Observatory (Lake Michigan, 2012-2014).Caution should be employed when using or interpreting these data, for reasons that include the following:1. Data were collected by multiple surveyors using differing survey methods. Survey locations, frequency, transect density, altitude, plane speed, and other methodologies may have varied, and these variations have the potential to cause variations in detection or identification rates of waterbirds between surveys and between surveyors.2. Many surveys did not include on-transect effort information (for example, GPS transects of survey effort, to enable clear identification of areas that were surveyed and where birds were not found). For surveys that did not include this information, approximate effort data were developed using idealized transects and observation locations, but this is a poor substitute for real effort data. The effort data associated with this dataset should be used with extreme caution, and it is recommended that they are not used for estimating bird densities.3. The majority of data do not include distance information, or include different distance bands between years or survey areas. This largely precludes the correction of counts to include estimates of animals that were present but not observed. As a result, these data cannot be used to estimate real or absolute abundance of pelagic waterbirds, but rather should only be used to develop estimates of relative abundance.4. Surveys were primarily conducted during fall and spring, and were designed to study open-water (pelagic) migratory waterbirds. These surveys did a poor job of capturing the presence of breeding birds and non-waterbirds, including passerines, shorebirds, and raptors.
