Lighthouses - Hawaii

Data provided by  National Oceanic and Atmospheric Administration

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.

Chlorophyll-a Average Annual Frequency of Anomalies, 2002-2013 - Hawaii

Data provided by  National Oceanic and Atmospheric Administration

Chlorophyll-a is a widely used proxy for phytoplankton biomass and an indicator for changes in phytoplankton production. As an essential source of energy in the marine environment, the extent and availability of phytoplankton biomass can be highly influential for fisheries production and dictate trophic structure in marine ecosystems. Changes in phytoplankton biomass are predominantly effected by changes in nutrient availability, through either natural (e.g., turbulent ocean mixing) or anthropogenic (e.g., agricultural runoff) processes.

Coastal Habitat Modification - Hawaii

Data provided by  National Oceanic and Atmospheric Administration

Coastal habitats are utilized and altered for a suite of human uses. Habitat modification is here defined as the alteration or removal of geomorphic structure as a result of human use. This includes several habitat-modifying features like seawalls, piers, breakwaters, dredged areas, artificial land (i.e., filled wetlands), and offshore structures. This data layer represents the presence of habitat modification in shallow waters of the Main Hawaiian Islands.

Total Estimated Average Annual Catch of Reef Fish, 2003-2013 - Hawaii

Data provided by  National Oceanic and Atmospheric Administration

Nearshore fisheries in the Main Hawaiian Islands encompass a diverse group of fishers using a wide array of gears and targeting many different species. Communities in Hawaii often rely on these fisheries for economic, social, and cultural services. However, the stress from overfishing can cause ecosystem degradation and long-term economic loss. This layer represents the estimated average annual catch of reef fish by all gear types and fishers (kg/ha).
