Greenland: a Greenland Traverse for Accumulation and Climate Studies (GreenTrACS)
This project will use a hand auger and sidewinder to drill several shallow (20-30 meter depth) ice cores along a traverse in western Greenland from Raven to Summit via snowmobile during the 2016 Arctic season. Continuous ground penetrating radar data will also be collected during the traverse. The research objectives include: (1) determining the patterns, in time and space, of snow accumulation in Western Greenland over the past 20-40 years; and (2) evaluating surface melt refreeze and englacial meltwater storage in the Western Greenland percolation zone over the past 20-40 years.
North America: Microbes Promote Ice Formation in Inland Waters
This project involves the seasonal (winter) acquisition of cores from ice-covered northern (U.S. midwest) temperate lakes and rivers to investigate the spatial and temporal distribution of planktonic ice nucleating activity in fresh water ecosystems.
