New research led by the University of Sydney enhances our understanding of how fast the sea level is increasing due to climate change, which is why we know that the great barrier offers the end of the reef as we know.
These results show that rock can cope with the rising level of isolation in isolation, but is associated with environmental pressure caused by global climate change.
This research was published today, headed by Professor Judy Webster of the School of GeoSins Nature communications. It draws from the capsule of the fossil reef cores, which is extracted from the sea edge under the great barrier reef.
These results suggest that the rapid surface increase in isolation did not make the predecessor of the reef, the end of the reef 4, but rather, the environmental tension such as the poor quality and warm climate of the water, such as the end of the end of 10,000 years before the elimination of it).
In the coming to two to two thousand years, the transfer of Reef 4 was seen. Its shallow reef has moved towards the Earth so that we know nowadays that we can re -establish themselves as a great barrier reef.
“This research shows us a healthy, active barrier reef that can develop well in response to the rapid rise in sea level,” said Professor Webster. “It is a combination of extra environmental stress, which is above the rapid rise at the surface, which leads to its death.
These results already debt to the Great Barrier Reef already debt.
“Modern reef faces rising sesame and input of nutrients as well as rising sea levels, high heat waves and widespread bleach. This combination, above the growing sea level, is of deep concern.
“It will die, but its features can change. We will see a different storage of coral species, probably not easy and structurally complicated.”

Covers of 15 to 20 meters producing this research include a mixture of fossil corals, alkali and sesame seeds. They reveal how the previous avatar of Reef responded to the rise in sea levels. The core has been analyzed for this research how the reef ecosystem developed between 13,000 and 10,000 years ago.
Particularly interesting for Professor Webster’s team was that Milt Water Plus was known as 1B, 11,450 to 11,100 years ago, when sea level increased very rapidly.
“This 350 -year -old is very important,” said Professor Webster. “This is the period when polar ice sheets are thought to be experiencing sharp melting due to heat temperatures. Based on Barbados’ records, we thought earlier that it was currently increasing the surface of about 40 mm in a year.
“Our research shows that this rise was not so big and sharp. It was more likely to be in order of three to five mm a year, compared to what we are experiencing today.”
At a depth of 40 to 50 meters, the Great Barrier was removed from the bottom of the shelf Edge, a drilling ship, the cores offered new insights on how the reef 4, also known as the prototerous barrier reef, was affected by the rising sea level.
Professor Webster said, “Ref 4 is very interesting.” It had similar shapes for modern great barrier reef and a mixture of coral reef communities. Comparison of types of alkaline and coral and their growth rate is compared.
“Understanding climate change, which affected it, and led to its ultimate transition, so indicates what modern reef can happen.”
Professor Webster and colleagues used radiatic dating and reef hebei tet information to accurately identify the basic samples related to the melt water pulse 1b.
The Corps International Ocean Discovery Program, which clarified this research, was obtained under the International Ocean Drilling Program (IODP), an international maritime research cooperation comprising 21 countries.
Professor Webster said his latest research highlights the importance of IODP and shows the value of these records that have deep drills under the sea. They provide palloomet and Palo Environmental data, which over time goes far beyond the device records that return for only 50 to 100 years.
“These data allow us to understand how the reef and coastal ecosystem have responded to climate change, as the surface we face today is like an increase in sea and temperature.”
Professor Webster completed the research with colleagues at the University of Tokyo, Australian National University, Nagoya University, University of Granada and Aix-Merryille University.
