Adjunct assistant professor John Fegyveresi publishes in Cryosphere
Adjunct assistant professor John Fegyveresi and colleagues have published “Surface formation, preservation, and history of low-porosity crusts at the WAIS Divide site, West Antarctica” in The Cryosphere. “Observations at the West Antarctic Ice Sheet (WAIS) Divide site show that near-surface snow is strongly altered by weather-related processes such as strong winds and temperature fluctuations, producing features that are recognizable in the deep ice core,” Fegyveresi and his co-authors write. “Time variations in crust occurrence in the core may provide paleoclimatic information, although additional studies are required. Discontinuity and cracking of crusts likely explain why crusts do not produce significant anomalies in other paleoclimatic records.”
