Collaborative Research: Definition of High Resolution Seismic Facies for Interpreting Glacial Fluctuations

点击翻译按钮获取中文摘要

This award is for support of a three year investigation to characterize seismic reflection facies of temperate glaciers in order to help infer climatic, glaciologic and marine conditions associated with the Last Glacial Maximum (LGM) advance and subsequent retreat in Glacier Bay, Alaska. The study will use the R/V Alpha Helix for collection of data by seismic reflection profiling, side scan sonar, and piston and gravity coring. This work will provide critical data for modeling the depositional systems of glacial grounding lines. This is a collaborative research project between Northern Illinois University and Appalachian State University.
