Scientists announced today that a core drilled in Antarctica has yielded 2.7-million-year-old ice, an astonishing find 1.7 million years older than the previous record-holder. A European research consortium, in which the University of Bern is involved in, wants to drill a 1.5 million year old ice core in Antarctica. Why is “oldest” significant? Analysis of the ice showed that the concentration of carbon dioxide in the Earth's atmosphere was higher than in the oldest ice core previously, which was 800,000 years old. During the past one million years the cycle of ice ages followed by warm periods occurred every 100,000 years. The Earth is some 4.5 billion years old with humanity taking up not more than 200,000 years. Buried alpine glacier ice was discovered two decades ago in the McMurdo Dry Valleys, a predominantly ice-free region roughly the size of Rhode Island. For a long time, the Valleys remained stable and unchanged, but in recent years, they started to thaw. In both samples, radiolabeled substrates were incorporated into macromolecules, and microbes grew in nutrient-enriched meltwaters, but metabolic activity and cell viability were critically compromised with age. An analysis of the gases trapped in the oldest ice on Earth may be able to solve this problem. Drilling miles beneath the surface of Antarctica, researchers hope to uncover the secrets of our planet's distant past.

In both samples, radiolabeled substrates were incorporated into macromolecules, and microbes grew in nutrient-enriched meltwaters, but metabolic activity and cell viability were critically compromised with age. The team realised that the new, more precise date of the impact meant that most of the Earth, including Australia, was covered with thick ice sheets at the time. “And 11,000 years ago we were under several hundred feet of water—glacial Lake Agassiz.”. Putkonen and his team of scientists and students were at the site earlier this year extracting ice cores. Two million-year old ice from Antarctica recently uncovered by a team of researchers provides a clearer picture into the connections between greenhouse gases and climate in ancient times and will help scientists understand future climate change. “We want to double the length of that record to investigate an important shift in Earth’s climate around one million years ago, when the planet’s climate cycle between cold glacial conditions and warmer interludes changed from being dominated by a 41,000-year pattern to a 100,000 year cycle,” … "That's an important baseline for understanding climate science and calibrating models that predict future change," Brook said. A helicopter carries part of a drilling rig from a campsite to another site in the dry Antarctic valley. Heat from the Earth's core tends to melt the super deep layers of ice over time, and the oldest ice core scientists thought they were able to harvest was around 800,000 years old.
