One of the few regions within the U.S. Fish and Wildlife Service (USFWS) National Wildlife Refuge System (NWRS) with a marine component, Midway Atoll is one of the most remote coral atolls on Earth, located near the edge of the Northwestern Hawaiian Islands (NWHI). Nearly two million birds call it home for much of each year, including the world's largest population of Laysan Albatrosses, or "gooney birds". Hawaiian monk seals, green sea turtles, and spinner dolphins all frequent the lagoon.

Perennial and non-perennial streams in the Main Hawaiian Islands. Data accessed from the Hawaii Statewide GIS Program.

Arcs were extracted from the 1983 USGS Digital Line Graphs (DLG) hydrography layers based on the State of Hawaii Commission on Water Resources Management (CWRM) Hawaii Stream Assessment (HSA) maps and database, then coded with the HSA stream code, and the HSA stream name (1993). The State of Hawaii Division of Aquatic Resources (DAR) added additional streams from the DLG hydrography layer, and added additional attribute data.

This dataset was created using the Large Landowners layer that was derived from the Tax Map Key (TMK) Parcel shapefiles from the counties of Honolulu, Kauai, Maui and Hawaii. Lands were selected for Type = "Public".

The Hawaiian Ko'a Card (Coral Card) was developed by the Coral Reef Ecology Lab of the Hawaii Institute of Marine Biology (HIMB) at the University of Hawaii at Manoa to record changes in coral color of Hawaiian corals and provide a tool for people to monitor coral color as an indicator of coral health. The Ko'a Card was designed for use by everyone, including the community, citizen scientists, researchers, students, resource managers, recreational users, and visitors alike. Coral color health scores are based on actual colors of bleached and healthy Hawaiian corals.

The Hawaii Coral Reef Assessment and Monitoring Program (CRAMP) was created during 1997-98 by leading coral reef researchers, managers and educators in Hawaii. The initial task was to develop a statewide network consisting of over 30 long-term coral reef monitoring sites and an associated database. Upon completion of the monitoring network the focus was expanded to include rapid quantitative assessments and habitat mapping on a statewide spatial scale. Today the emphasis is on using these tools to understand the ecology of Hawaiian coral reefs in relation to other geographic areas.

A 50-m resolution grayscale hillshade of all available bathymetry (ocean depth) data for the main Hawaiian islands, including ship-borne multibeam sonar surveys, from the Hawaii Mapping Research Group (HMRG) in the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaii at Manoa. For the related dataset containing numeric bathymetry values for this image layer, see http://pacioos.org/metadata/hmrg_bathy_50m_mhi.html

A 60-m resolution grayscale hillshade of all available bathymetry (ocean depth) data for the Northwestern Hawaiian Islands (NWHI), including ship-borne multibeam sonar surveys merged with lower resolution (1-km) global bathymetry from SRTM30+. Because of its remote location, dedicated multibeam mapping of the NWHI region began only in the year 2000. In an effort to consolidate the more recent systematic surveys with older transit data swaths for this region, a synthesis of all existing multibeam data was undertaken beginning in 2009, with a fourth revision completed in mid 2015.

Locations of day-use mooring buoys within the waters surrounding the Main Hawaiian Islands. Installed and maintained by the Malama Kai Foundation, these buoys provide a convenient means of securing boats in popular dive and snorkel spots to prevent damage to coral reefs caused by anchors.

The Habitat Blueprint provides a forward-looking framework for NOAA to think and act strategically across programs and with partner organizations to improve coastal and marine habitats for fisheries, marine life, and coastal communities. This layer outlines the Habitat Blueprint project boundary for a portion of the west coast of Hawaii Island (Big Island).
