Marine scientists tracked coral colonies in a remote area of the Great Barrier Reef and found that corals previously more resilient to bleaching suffered devastating and fatal bleaching during ...
Bleached and dead coral around Lizard Island on the Great Barrier Reef, north of Cairns, Australia. ... A bleached coral is not dead, but ocean temperatures need to cool off for any hope of recovery.
The Great Barrier Reef Marine Park Authority (GBRMPA), the agency tasked with monitoring the reef's health, confirmed that "a widespread, often called mass, coral bleaching event is unfolding ...
The Great Barrier Reef experienced its first major bleaching event in 1998. Since then, bleaching events have increased in frequency, with three events occurring in the years 2016–2020. [53] Bleaching is predicted to occur three times a decade on the Great Barrier Reef if warming is kept to 1.5 °C, increasing every other year to 2 °C. [54]
A major coral bleaching event took place on this part of the Great Barrier Reef. The Great Barrier Reef is the world's largest reef systems, stretching along the East coast of Australia from the northern tip down at Cape York to the town of Bundaberg, [1] [2] is composed of roughly 2,900 individual reefs and 940 islands and cays that stretch for 2,300 kilometres (1,616 mi) and cover an area of ...
The increase mass coral dead zones is reinforced by the spread of coral diseases. Coral diseases can spread easily when there are high concentrations of sulfide and hypoxic conditions. Due to the loop of hypoxia and coral reef mortality, the fish and other marine life that inhabit the coral reefs have a change in behavioral in response to the ...
Covering nearly 133,000 square miles (345,000 square kilometers), the Great Barrier Reef is the world’s largest coral reef, home to more than 1,500 species of fish and 411 species of hard corals.
During that time, between 2016 and 2024, the Great Barrier Reef, the world’s largest coral reef ecosystem and one of the most biodiverse, suffered mass coral bleaching events.
