A 253-year coral core from Olowalu Reef on West Maui reveals how land use and climate change have affected the reef. Published in Coral Reefs, the study shows increased sediment and nutrient inputs, especially during sugarcane expansion, which correlates with declining coral growth.

The ocean absorbs 27% of human caused carbon dioxide emissions. As the CO₂ reacts with seawater, ocean pH decreases causing #OceanAcidification. 🧪🌊🦑

📈📉 by NOAA and @soest.hawaii.edu

The National Oceanic and Atmospheric Administration's Carbon Program at the Pacific Marine Environmental Laboratory leads a global ocean observing program to track seawater carbon dioxide and ocean acidification.

In this graph from the Hawaii Carbon Dioxide Time-Series, the red data are observations from the Mauna Loa observatory monitoring atmospheric carbon dioxide, the green data are observations from the University of Hawaii at Mānoa ocean station ALOHA monitoring seawater carbon dioxide, and the blue data are observations from ALOHA monitoring seawater pH.

A UH Mānoa study reveals the Moon's soil acts as a cosmic time capsule, preserving supernova history for 100 million years. Researchers developed a mathematical model to decode this "impact gardening," helping future Artemis astronauts read scrambled lunar layers for clues about galactic history.

Climate change is making Hawaiʻi more dangerous. While long-term data show that Hawaiʻi is getting drier overall, short, intense downpours that cause sudden, dangerous flash floods are getting stronger in the islands.

A study by the University of Hawai‘i at Mānoa found that human activities alter coral reef chemistry, reducing their resilience to environmental stressors. Researchers discovered 25 contaminants from various sources accumulating in coral tissues, leading to decreased nutrient and energy reserves. 🧪
