Displays the location of buoys for the State of Hawaii as recorded on NOAA nautical charts, which are used as aids to navigation (ATONs) to indicate traffic channels, to warn against potential dangers, or for other navigational purposes. Some include lights or radar reflectors to make them visible at night and in conditions of reduced visibility. In the IALA B maritime buoyage system (North and South America), red lateral markers have even numbers and should remain on your right when returning from sea ("red, right, returning") while green lateral markers have odd numbers and should remain on your left. Other colors and color combinations are used for non-lateral markers with a variety of purposes.

Displays the locations of lights for the State of Hawaii as recorded on NOAA nautical charts. These aids to navigation (ATONs) are used in conjunction with beacons and buoys to indicate traffic channels, to warn against potential dangers, or for other navigational purposes.

Locations of lighthouses and minor coastal lights for the State of Hawaii. These aids to navigation (ATONs) are used to mark dangerous coastlines, hazardous shoals and reefs, and safe entries to harbors and can assist in both marine and aerial navigation. Information regarding the lamp light (color, range, elevation, etc.) is also provided as determined from NOAA nautical charts.

Beacon locations around Saipan, Commonwealth of the Northern Mariana Islands (CNMI).

This data set identifies aids to navigation, or ATONs, such as lights, signals, buoys, and day beacons, that are intended to assist a navigator to determine position or safe course, or to warn of dangers or obstructions to navigation. The U.S. Coast Guard is responsible for ensuring that this network is up to date and functioning properly so recreational and commercial boaters can safely navigate the maritime environment. Not for navigation.

Displays the point location of anchorages and non-anchorages for the State of Hawaii as recorded on NOAA nautical charts. These are offshore areas outside of harbors where ships and boats can lie at anchor; many offer natural shelter from the effects of storms. Some anchorage zones have usage restrictions while others are prohibited entirely. These are indicated herein by marker color. See also the associated "Anchorage Zones - Hawaii" layer for related polygon boundaries.

Wave buoy 165 measures wave height, wave direction, wave period, and water temperature in the vicinity of Barbers Point on the leeward (western) coast of Oahu in the State of Hawaii. Data are transmitted every half hour. Moored in water 300 meters deep, this Datawell Directional Waverider Mark III (DWR-MkIII) buoy is equipped with three accelerometers measuring north/south, east/west, and vertical displacements, allowing it to measure both wave direction and wave energy. The temperature sensor is located at the base of the 0.9 meter spherical buoy, approximately 45 cm or 18 inches below the ocean surface. Wave buoys are useful tools for forecasting local waves and are used by recreational and professional ocean users alike. For recent wave observations at a nearby location, please visit the Kalaeloa Barbers Point wave buoy (cdip238). Because this historical Barbers Point buoy location experienced significant damage during vessel strikes, it was decommissioned and later replaced by the Kalaeloa Barbers Point wave buoy in a less frequented area to help avoid future collisions.

Wave buoy 198 measures wave height, wave direction, wave period, and water temperature in the vicinity of Kaneohe Bay on the windward (eastern) coast of Oahu in the State of Hawaii. Data are transmitted every half hour. Moored in water 81 meters deep, this Datawell Directional Waverider Mark III (DWR-MkIII) buoy is equipped with three accelerometers measuring north/south, east/west, and vertical displacements, allowing it to measure both wave direction and wave energy. The temperature sensor is located at the base of the 0.9 meter spherical buoy, approximately 45 cm or 18 inches below the ocean surface. Wave buoys are useful tools for forecasting local waves and are used by recreational and professional ocean users alike.

Wave buoy 106 measures wave height, wave direction, wave period, and water temperature in the vicinity of Waimea Bay on the North Shore of Oahu in the State of Hawaii. Data are transmitted every half hour. Moored in water 200 meters deep, this Datawell Directional Waverider Mark III (DWR-MkIII) buoy is equipped with three accelerometers measuring north/south, east/west, and vertical displacements, allowing it to measure both wave direction and wave energy. The temperature sensor is located at the base of the 0.9 meter spherical buoy, approximately 45 cm or 18 inches below the ocean surface.
