Pressures

Of the years 1985 to 2025, 2025 brought the most coral heat stress: averaged over the park, the year's highest Degree Heating Weeks reached 22.3 °C-weeks. NOAA counts 4 °C-weeks as bleaching likely and 8 as severe bleaching and mortality likely.NOAA Coral Reef Watch · Public domain
The 2013 cumulative human impact score (Halpern et al. 2015) averages 3.69 across the park, from 2.41 to 4.68.Halpern et al. 2015 · CC0 1.0

Data and research

157 of the 1,475 world map layers on Biohotspot with an open licence have data inside the park.

A park here is the CAPAD 2024 Marine zones that share a name and a state. Habitat areas are the habitat maps’ polygons inside the park; carbon, heat stress and human impact are the map cells that touch it. Only sources with an open licence are used. Computed on 2026-10-27.
