11th International Symposium on Antarctic Earth Sciences

Over 500 researches from around the world gathered at the 11th International Symposium on Antarctic Earth Sciences in Edinburgh, Scotland from July 10-16, to share their latest research findings from Antarctica. Scientists exchanged their perspectives about future climate change based on their continued study of Antarctic geological archives and ice cores.

Study Reveals Climate History of Antarctic Peninsula

“Fossilized pollen found in glacial core samples played a role in a study reconstructing the climatic history of the Antarctic Peninsula and provided a glimpse into the rate at which plants disappeared as the ice spread over the last 35 million years. The Antarctic Peninsula, the northernmost part of Antarctica, was the last area to be covered by ice. Drilling techniques similar to those found in the oil industry were used to examine the history of the initial growth of the ice sheet across the Antarctic Peninsula.”

Ocean Sediment Cores Reveal Detailed History of Glaciation along Antarctic Peninsula

A detailed, three-year examination of sediment cores extracted from the continental shelves of Antarctica has revealed that the last remnant of vegetation existed in a tundra landscape on the continent’s northern peninsula about 12 million years ago.
The new study contains the most detailed reconstruction to date of the climatic history of the Antarctic Peninsula, which is one of the fastest warming regions on the planet.
“The best way to predict future changes in the behavior of Antarctic ice sheets and their influence on climate is to understand their past,” said Rice University marine geologist John Anderson External Non-U.S. government site, the study’s lead author.
