Olowalu reef off Maui provides glimpse into two centuries of environmental changes

New research led by the University of Hawai'i Sea Grant College Program (Hawai'i Sea Grant), the UH Mānoa School of Ocean and Earth Science and Technology (SOEST) and the U.S. Geological Survey analyzed a 253-year-old core from a massive coral colony at Olowalu Reef off West Maui to reconstruct how Olowalu has changed over time, what has driven those changes and what restoring healthy connections between land and sea may mean for the reef's future.
