The effect on Icelandic glaciers of supraglacial deposition of tephra from the Eyjafjallajökull 2010 eruption (2015)
Presentation / Conference Contribution

The explosive eruption of Eyjafjallajökull, Iceland, between April and May 2010 deposited supraglacial tephra on the surfaces of glaciers across Iceland. While the initial effects of the eruption caused glacial melting, there may have been longer ter...

The role of cold supraglacial volcanic deposits in influencing glacial ablation (2014)
Thesis

An often overlooked factor in glacial ablation is the influence of supraglacial debris deposits, which can have both positive and negative effects. A critical thickness exists at which sub-debris ablation is equal to that of bare ice; debris will hin...

Global database on large magnitude explosive volcanic eruptions (LaMEVE) (2012)
Journal Article

© 2012 Crosweller et al. To facilitate the assessment of hazards and risk from volcanoes, we have created a comprehensive global database of Quaternary Large Magnitude Explosive Volcanic Eruptions (LaMEVE). This forms part of the larger Volcanic Glob... Read More about Global database on large magnitude explosive volcanic eruptions (LaMEVE).

The role of cold volcanic debris in glacier ablation. AGU fall meeting EP51B-0846 (2011)
Presentation / Conference Contribution

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 Contribution

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...

Analysis of a global database on quaternary explosive volcanism (2009)
Presentation / Conference Contribution

Large volcanic eruptions, despite their low frequency of occurrence, have the potential to cause massive loss of life and affect the health of humans and animals and cause major economic losses. The knowledge of the evolution of past volcanic process... Read More about Analysis of a global database on quaternary explosive volcanism.

Partitioning of SO2 between dacitic melt and aqueous fluid phases (2009)
Presentation / Conference Contribution

Sulphur dioxide has significant effects on global climate. By combining with atmospheric water molecules to form H2SO4 aerosols, which strongly backscatter sunlight, it can cause a potentially global net reduction in temperature following a large exp...

Adsorption of HCl onto volcanic ash (2009)
Journal Article

HCl molecules emitted from volcanoes breakdown to form chlorine free radicals via heterogeneous chemical reactions and photolysis, which act as catalysts to the breakdown of ozone in the stratosphere. Ozone depletion of up to 2-7% was estimated follo... Read More about Adsorption of HCl onto volcanic ash.

Global database of large magnitude explosive eruptions for magnitude-frequency analysis (2008)
Journal Article

Large explosive volcanic eruptions can have severe consequences for life, property and climate. In the most extreme cases this can cause catastrophes on a global scale. Extreme value statistics can be used to evaluate the magnitude-frequency relation... Read More about Global database of large magnitude explosive eruptions for magnitude-frequency analysis.

Global frequency of large magnitude explosive volcanic eruptions recorded in the last 100,000 years (2008)
Thesis

The effects of large magnitude (M ≥4.0) explosive eruptions can be catastrophic on a local and potentially global scale. The largest eruptions (M ≥8.0) can disperse ejecta over thousands of km2. As the last known event of this kind took place ~26,500... Read More about Global frequency of large magnitude explosive volcanic eruptions recorded in the last 100,000 years.
