Great Lakes Water Quality

The Great Lakes Restoration Initiative is a five year $475 million plan developed and led by the U.S. Environmental Protection Agency in collaboration with 15 other federal agencies, including the National Park Service. The Initiative is meant to help protect and restore the chemical, physical and biological integrity of the Great Lakes Basin ecosystem. Use this interactive map to view water quality rankings and information from sites found inside and outside of the Great Lakes national parks.

Marine Ecosystem Data Viewer

This viewer provides an interactive look at geospatial data which the NOAA Biogeography Branch collected and integrated to support NPS management of marine resources in eight coral reef park units. The focus of activities was to identify, obtain, synthesize, and evaluate all relevant ecological, oceanographic, socio-economic, cultural, and remote sensing datasets. The products from this effort provide an accurate, contemporary assessment of the abundance and distribution of biological, physical, and socioeconomic information within coral reef parks to support more effective management and conservation of ocean resources within these parks.

The Natural Resources Stewardship & Science directorate (NRSS) developed shoreline maps for ocean and coastal parks using publicly available imagery and park boundaries from the NPS Land Resources Program (LRP). Slightly more than half of the ocean and coastal parks have LRP-approved boundaries; the boundaries of the remaining parks are provisionary until approved by the LRP.

Seafloor Habitat Maps

Seafloor habitat maps provide park managers with better information about the location and condition of submerged resources and support resource assessments and management planning. The maps establish baseline conditions for future monitoring and can inform post-incident (e.g., storms, ship groundings, oil spills, etc.) management decisions. The NRSS co-hosted an interagency habitat mapping workshop with USGS in 2008 as the first step in developing a seafloor habitat mapping program.
