Deglacial changes in the West Atlantic Ocean traffic – ScienceDaily

A new study by an international team of researchers using ocean sediment chemistry has highlighted a widespread picture of changes in Atlantic traffic badociated with rapid climate change in the past.

The Journal Nature Communications provides new insights into the interactions of ice melt, ocean circulation, and climate change, with potential implications for future long-term changes in terrestrial systems with global climate change. He said: "Rapid and significant changes in climate, carbon dioxide and ice sheet volume have occurred when the planet emerged from the most recent ice age. 20,000 years ago.

"Changes in the circulation of the Atlantic Ocean are thought to have played an important role in the conduct of these climatic events – but direct evidence has been" In this study, we badyzed radioactive elements in oceanic sediments to provide a much better-constrained picture of the strength of ocean circulation in the past, and thus its relationship to ice cap time and climate change "

The study gathered the results of sediment cores from the other side of the Atlantic and revealed changes in circulation in the Atlantic that coincide with rapid climatic transitions during the deglacial period

Dr Ng added: the first time that spatially consistent and extensive observations (from the tropics to high latitudes) have been collected on a common age scale.

"We found that the ocean slowed down its circulation in two stages, related to two episodes of ice melt – one in Eurasia and one in North America."

The results highlight the role of ice melt in slowing ocean circulation.

It's Important, Say New data can be used to test the response of climate models to changes in ice melt and ocean circulation during rapid climate transitions
