How Climate Patterns Contribute to Coral Bleaching in the Great Barrier Reef: A study led by UNSW Sydney reveals that the El Niño Southern Oscillation (ENSO) and the Madden-Julian Oscillation (MJO) significantly impact coral bleaching in the Great Barrier Reef. While ENSO affects seasonal weather patterns, MJO influences short-term weather variability, altering ocean temperatures and increasing bleaching risk. This research underscores the need for comprehensive forecasting models incorporating both ENSO and MJO to better predict and manage coral bleaching events.

Algae Blooms on Coral Reefs Linked to Environmental Changes: A study by the University of Queensland highlights how environmental changes, particularly nutrient pollution and overfishing, contribute to algae blooms on coral reefs. These blooms disrupt the delicate balance of reef ecosystems, outcompeting corals for space and resources. The research underscores the importance of managing local stressors, such as agricultural runoff and fishing practices, to protect and preserve coral reef health amid broader climate change impacts.

Origins of Beach Sand: Beach sand primarily comes from the erosion of inland rocks and coastal cliffs, transported to the shore by rivers and waves. Coral reefs and shellfish also contribute, breaking down into finer particles over time. Human activities like construction can introduce additional materials. The composition of sand varies by location, often reflecting the local geology. This diverse mix of sources results in the varied textures and colors observed in beach sands worldwide.

NATURE
