Description of gauge:
The Main Hawaiian islands score a 71, meaning they are ranked fair with some indicators meeting reference values.
Description of Hawaiian Archipelago:
The Hawaiian Archipelago includes the state of Hawai‘i and the Northwestern Hawaiian Islands. The archipelago consists of volcanic islands, atolls, and seamounts that stretch over 1500 miles from southeast to northwest. The National Coral Reef Monitoring Program status report, has two main regions, the Main Hawaiian Islands (the State of Hawai‘i) and the Northwestern Hawaiian Islands. The Main Hawaiian Islands were further sub-divided into four regions based on geographic location and data availability. The four regions are O‘ahu, Hawai‘i, Maui Nui, and Kaua‘i/Ni‘ihau.
How Coral Reef indicator data are compiled and scored:
The coral reef ecosystem scores shown here were analyzed using data from the National Coral Reef Monitoring Program (NCRMP). NCRMP collects data in all U.S. coral reef regions in four themes: benthic (corals and algae), reef fish, climate (ocean acidification and thermal stress), and human connections (socioeconomic surveys). The scores you see for each region are composite scores from all four themes assessed together and rolled into one overall score.
Overall scores mean the following:
90-100% Very good: All or almost all indicators meet reference values.
80-89% Good: Most indicators meet reference values.
70-79% Fair: Some indicators meet reference values.
60-69% Impaired: Few indicators meet reference values.
0-59% Critical: Very few or no indicators meet reference values.
Scores in the Pacific coral reef gauges were released in 2018, and largely used data from 2012-2016 to determine the scores.
