The role of cold volcanic debris in glacier ablation. AGU fall meeting EP51B-0846 (2011)
Presentation / Conference
Hobbs, L., Gilbert, J., & Lane, S. (2011, December). The role of cold volcanic debris in glacier ablation. AGU fall meeting EP51B-0846. Presented at AGU Fall Meeting 2011, San Francisco, USA

Debris deposits on ice can either enhance or hinder glacial ablation relative to a clean ice surface. The effect of debris on ice is dependent on whether its thickness is above or below a critical thickness. This is the thickness at which ablation of...

The significance of volcanic ash fall for Earth’s glaciers (2011)
Presentation / Conference
Hobbs, L., Gilbert, J., & Lane, S. (2011, January). The significance of volcanic ash fall for Earth’s glaciers. Poster presented at Volcanic and Magmatic Studies Group Conference, Cambridge, UK

Worldwide glacier mass changes are key indicators of global climatic change [1]. The effect of volcanic air fall, which may enhance or hinder ablation depending primarily on deposit thickness, is a potentially important driver of glacial change. Belo...
