Volatiles In Subglacially Erupted Basaltic Glasses And Their Use In Reconstructing Paleo-Ice Thicknesses, Carver Lee Mar 2017

Volatiles In Subglacially Erupted Basaltic Glasses And Their Use In Reconstructing Paleo-Ice Thicknesses, Carver Lee

Masters Theses

Volatile concentrations in basaltic tuyas, edifices that form during a subglacial eruption and remain once the ice sheet has retreated, have been used to calculate the thickness of the overlying ice sheet at the onset of the eruption (Tuffen, 2010). However, subglacial eruptions are complex events and this technique does not always provide a clear answer (Schopka et al., 2006; Edwards et al., 2009). The purpose of this research is to evaluate this technique and investigate constraints on the quality of data collected by attempting to calculate the minimum ice thickness under which Hlöðufell, a tuya in south-central Iceland, erupted. …

Detecting Atmospheric Carbon Dioxide With Btb, Stephan Schneider

IPY STEM Polar Connections

A study of the concentration of carbon dioxide gas in air samples requires an understanding of effective sampling techniques, the use of pH indicators, an understanding of chemical reactions that result on the formation of acidic compounds, and an understanding of the chemical processes that contribute to the composition and characteristics of Earth’s atmosphere.
