Seeking, Retrieving Samples of the Oldest Ice

In collaboration with the federally funded COLDEX initiative, their mission involves seeking out and retrieving samples of the oldest ice, dating back around 800,000 years. 

Interesting Engineering reported that this endeavor aims to enhance our understanding of climate change by analyzing past climates, with a particular focus on greenhouse gas levels and their influence on Earth's climate. 

The significance of ice cores in providing crucial insights into the fundamental workings of our planet's climate underscores the importance of this research initiative. During the seven-week expedition, the team establishes camps on the Antarctic ice to collect samples. 

Extending Ice Core Record

Their primary objective is to extend the continuous ice core record beyond 800,000 years, reaching back to 1.5 million years or even further. The aim is to gain insights into the various ways the climate system behaves under warmer conditions.

The mission has a primary goal of advancing our comprehension of Earth's climate and its historical patterns. As part of this endeavor, scientific teams are engaging in an extensive expedition in Antarctica. 

CBS reported that their focus is on locating and extracting samples of the oldest ice, utilizing drilling techniques to obtain ice cores from deep within the Antarctic ice.

To prevent any risk of melting, the extracted ice cores are carefully transported in climate-controlled packaging during their journey from Antarctica to the United States.

Upon reaching the U.S., these ice cores will be subjected to thorough analysis in various university laboratories, including Princeton University. The researchers will specifically examine the trapped air bubbles within the ice to extract valuable climate data.

One of the field researchers, Sarah Shackleton, expressed her fascination with the process, highlighting the intriguing journey of these ancient air bubbles from the atmosphere millions of years ago to their current state in New Jersey, where they will be measured.

The ultimate aim of this comprehensive study is to gain insights into historical greenhouse gas levels, particularly carbon dioxide, contributing essential information to the understanding of Earth's past climate changes and providing a valuable context for interpreting ongoing climate change trends.

The quest for the oldest ice extends beyond American scientists, as research teams from various countries are conducting independent missions in Antarctica with a shared objective. 

European and Australian teams are actively engaged in drilling operations across different regions of the continent.

The race to uncover the ancient ice holds international significance, and the team that succeeds in making this discovery is poised to attract global attention for its contributions to climate research.
