This Project Grant award, valued at $359,487, was provided by the National Science Foundation's Polar Programs (CFDA 47.078) to The Trustees of Princeton University. The funding will be used to develop advanced analytical methods for high-resolution chemical imaging and dating of ancient ice cores from Antarctica's Blue Ice Areas, which contain climate records spanning over 1 million years. Specifically, the project will utilize cryo-cell laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to precisely map elemental distributions within the ice layers and determine ages using strontium isotope ratios. This innovative approach aims to significantly enhance the interpretation of the age and stratigraphic orientation of deformed ancient ice, thereby creating more reliable paleoclimate archives. The research outcomes will contribute to ongoing initiatives to recover the oldest possible ice cores in Antarctica, extending past climate reconstructions beyond the million-year timescale. The award also includes training and mentorship of undergraduate and graduate students, as well as knowledge exchange and outreach activities through a collaboration with the Princeton Student Climate Initiative.
