Great Barrier Reef suffers 5th near-death experience in 30,000 years, which showed it an each sort of rises in the sea level, increasing sediment and changing temperature.
More acidic and warmer ocean under severe stress, the Great Barrier Reef in Australia has just got a sixth life since the past 30,000 years after experiencing a near-extinction event for fifth time in the period, which indicates that the reef is very much resilient than ever thought, as reported by associated researchers on Monday.
The research team determined by analyzing the fossil data obtained from the cores drilled in the 16 sites of the ocean floor that Great Barrier Reef was capable of migrating from 20 centimeters (i.e. 7.9 inches) to 5 meters a year.
During the investigation, the team found that the reef has had ever suffered through two ubiquitous occurrences because of the exposure with air nearly 22,000 and 30,000 years back, so that the reef shifted towards the sea in order to survive. later, two more near-extinction conditioned were faced by the reef because of rapidly rising sea level as about 13,000 and 17,000 years ago, after which the reef shifted backward to the land.
Co-authored of the paper published in the Nature Geoscience journal, Jody Webster from the University of Sydney said in a statement that, “I have grave concerns about the ability of the reef in its current form to survive the pace of change caused by the many current stresses and those projected into the near future.”
