FCGS Newsletter - February 2016

Newsletter Summary

Dr. Julia Wellner’s abstract describes how Antarctic sediment cores, geophysical surveys, and radiometric dating reveal past ice sheet extent, retreat rates, and links to high CO₂ climates. She contrasts diachronous ancient retreats with today’s rapid, widespread change. Her team integrates 3.5 kHz geophysical profiles, multibeam bathymetry, and sediment cores to reconstruct former ice sheet extent, flow speed, and retreat style. A new field trip is announced in early June: The Tocito, El Vado and Gallup Sands of the San Juan Basin with Dr. Leslie Wood.
