Science Summary:
The project will undertake an ultra high resolution, multi-parameter investigation of past climate to develop predictors for future abrupt climate change through identification of the "tipping points" which occur prior to an abrupt climate change events. Ultra-high resolution (up to 4 micron) ice core records will be produced -- well beyond the ~1cm resolution currently available -- using continuous flow injection into both a Thermo Element 2 ICP-MS and a Picarro Inc. L-2130-I H2O isotope analyzer sampled using a newly developed state-of-the-art cryocell chamber integrated with digital image recording and annotating software. The PI will look for precursors that reveal evidence of changes in, for example, the timing and magnitude of temperature, precipitation and atmospheric circulation from multi-decadal down to hundreds of sampling levels per year. The project will train students to be well versed in advanced laboratory and numerical modeling methods. Students will learn data reduction and visualization algorithms while also helping to provide a data stream that has broad applicability to climate. Cyberinfrastructure developed under NSF funding to the Climate Change Institute will be used to store, process, and visualize this high volume of ice core data while also making the information available to the public with high transparency for climate change use and attribution.

Logistics Summary:
This grant will conduct an even more in-depth investigation into ice cores, made available by transformative laser based ice core analysis, to probe into resolution levels far beyond those currently utilized and as a consequence search for precursors for abrupt change not previously recognizable. This grant addresses a critical Arctic, Antarctic and globally significant process (ACC) and our primary hypothesis (a search for ACC precursors) focuses directly on new understanding and the development of predictive tools. Researchers will produce ultra high resolution (up to 4 um) ice core records, well beyond the ~1cm resolution currently available, using continuous flow injection into both a Thermo Element 2 ICP-MS and a Picarro Inc. L-2130-i H2O isotope analyzer sampled using newly developed state-of-the art cryocell chamber integrated with digital image recording and annotating software. Researchers will search for precursors that reveal evidence of changes in, for example, the timing and magnitude of temperature, precipitation and atmospheric circulation from multi-decadal down to hundreds of sampling levels per year. No fieldwork is conducted.
