Dwarf sperm whales (Kogia sima) and pygmy sperm whales (Kogia breviceps) are the only two members of the Family Kogiidae. Both are found in Hawaiian waters. This overlay represents sightings of either species when they could not be sufficientily distinguished from each other. This collection is aggregated from multiple data sources and survey periods listed below. Each data point contains attributes for further information about the time and source of the observation.

This dataset contains a collection of known point locations of pygmy sperm whales identified through direct human observation via shipborne surveys. This can be useful for assessing species abundance, population structure, habitat use, and behavior. This collection is aggregated from multiple survey periods. Each data point contains attributes for further information about the time and source of the observation. This dataset was compiled by the Pacific Islands Ocean Observing System (PacIOOS) and may be updated in the future if additional data sources are acquired.

This dataset contains a collection of known point locations of whales identified either via automated satellite tracking of tagged organisms or through direct human observation via shipborne and aerial surveys. This can be useful for assessing species abundance, population structure, habitat use, and behavior. This collection is aggregated from multiple data sources and survey periods. Each data point contains attributes for further information about the time and source of the observation.

The Pacific Islands Ocean Observing System (PacIOOS), University of Hawaii School of Ocean and Earth Science and Technology Department of Oceanography, and Hawaii Sea Grant are developing a high-resolution, real-time wave run-up forecast and notification system for West Maui's coastline. In order to validate the site-specific, short-term forecasts and to determine meaningful thresholds associated with each forecast domain, citizen scientists contribute crowd-sourced photographs by documenting the shoreline of West Maui during predicted wave run-up events.

Displays the boundaries of anchorage zones and non-anchorage zones 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 polygon color. See also the associated "Anchorages - Hawaii" layer for related point locations.

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.

Displays the location of marine beacons for the State of Hawaii as recorded on NOAA nautical charts. While buoys float at the surface of the water, beacons are fixed to the sea bottom. Both 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.

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. 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.

Boundaries of bottomfish restricted fishing areas (BRFA) for the State of Hawaii. It is unlawful for any person to take or possess bottomfish while in a vessel that is drifting or anchored within any BRFA. Bottomfish species covered by these rules include: a) 'ula'ula koa'e or onaga (Etelis coruscans); b) 'ula'ula or ehu (Etelis carbunculus); c) kalekale (Pristipomoides sieboldii); d) 'opakapaka (Pristipomoides filamentosus); e) 'ukikiki or gindai (Pristipomoides zonatus); f) hapu'u (Epinephelus quernus); and g) lehi (Aphareus rutilans).
