Methane in Permafrost (new pursuit)
In ice core science, we utilize new laser-based technologies to recover high-resolution climate records. My focus is the measurement of water isotopes, a proxy for past temperature. Along with an incredible international team, we have recently recovered and analyzed 4 deep ice cores: WAIS Divide (West Antarctica), South Pole (East Antarctica), EGRIP (northeast Greenland), and Renland (an east Greenland coastal ice cap).
In partnership with local start-up Blackswift, we are also developing fixed-wing Unmanned Aerial Vehicles (UAVs) for isotopic sampling (water, methane) of the atmosphere. Initially, we plan to study the changing hydrologic cycle in Greenland and methane emissions from permafrost. The technology is transferrable to other disciplines, like volcanology or forest ecology.
