Summary
Abstract: This award supports a project to use two spectrofluorimeters - one with a 224-nm laser to excite protein fluorescence and non-protein aerosol and dust fluorescence, and the other with a 404-nm laser to excite F420 fluorescence (a proxy for methanogens) and chlorophyll fluorescence (a proxy for aerobes) - in order to scan ice core sections at NICL and look for abrupt climate changes, volcanic ash, ...

Description: WAIS Divide is a United States deep ice coring project in West Antarctica funded by the National Science Foundation (NSF) and is the second component to the larger WAISCORES initiative. The purpose of the WAIS Divide project is to collect a deep ice core from the flow divide in central West Antarctica in order to develop a unique series of interrelated climate, ice dynamics, and biologic records focused on understanding interactions among global earth systems.
