Pressures

• Of the years 1985 to 2025, 2011 brought the most coral heat stress: averaged over the park, the year's highest Degree Heating Weeks reached 25.1 °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 3.21 across the park, from 2.76 to 3.78.Halpern et al. 2015 · CC0 1.0

Data and research

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.
