This warming has driven large changes in the cryosphere: the Greenland Ice Sheet is currently the single largest contributor to sea level. Melt layers, or bubble-free layers in ice cores where surface melt percolates down into pore spaces and refreezes, are used as a proxy for positive-degree days when local temperatures rose above 0°C. Studying patterns of melting in past warm periods can illuminate how sensitive Greenland surface processes are to broader climate patterns. Noble gas elemental ratios may be used to identify melt layers in ice cores, as heavier noble gases like krypton (Kr) and xenon (Xe) become enriched in meltwater relative to lighter gases like argon (Ar) and nitrogen (N2). We have developed a wet extraction method targeted to produce low-volume, high-precision, high-resolution noble gas measurements with the goal of developing melt chronologies for several key warm periods across ice core sites in the Arctic. We measure δ15N with a mean precision of 15 per meg (0.015‰) standard error, in addition to elemental and isotopic concentrations of Ar, Kr, and Xe using a peak jumping mass spectrometry method.

Hailing from Richmond, Virginia, Dr. Tobias Keene brings a bit of unabashed Southern hospitality to all his patients. He moved to Washington, D.C. over thirty years ago as a freshman at Ivy College. Right after graduation, he attended World University’s School of Dentistry. Before opening Keene Dental in 1994, he worked for free clinics and some of the finest practices in the District. He is part of the 123 Dental Association and stays up-to-date on the latest dental discoveries. When not striving to keep his patients happy and healthy, he’s enjoys hiking with his family in Rock Creek Park.
