Mapping a 49 year old eruption of a basaltic cone: Pacaya Guatemala

27 Apr 2011 | Contributor(s): William I Rose

This presentation summarizes the 50 year eruption and the 3 dimensional map produced. The map, prepared as part of an MS thesis by Ruben Otoniel Matias Gomez, is under review as a Map and Chart Series publication by the GSA. The lecture summarizes the situation at Pacaya, and uses Matias' map as...

Mass Balance and Velocity Data for Greenland Ice Sheet at High Elevations

17 Sep 2021 | *Data Sets/Collections | Contributor(s): Beata Maria Csatho, Ash Narkevic, Ivan Parmuzin

This is an estimation of mass balance of the Greenland Ice Sheet at higher elevations, computed as the difference between the estimated annual total snow accumulation and ice discharge. Measurements are taken at 161 stations located 30 km apart, at 2000 m elevation that circumnavigates Greenland....

Matlab Codes for Volcanology - Stokes Rise Calculations for Bubbles

09 Aug 2013 | Offline Tools | Contributor(s): Tom D Pering

A series of Matlab codes for the determination of the rise speed of stokes bubbles at a single point (i.e. at a given depth and set radius) and over a range of depths. The aim of these files is to allow the calculation of rise speed given the overall bubble composition and the proportions or mass...

Modeling ice flow variability of the Kangerlussuaq Glacier, southeast Greenland, during 1900-2021

21 Apr 2023 | Presentations | Contributor(s): Eigil Yuichi Hyldgaard Lippert, M. Morlighem (contributor), C. Gong (contributor), S. Khan (contributor)

Observations show significant ice loss associated with the speed-up of the Kangerlussuaq Glacier (KG) in Greenland since the 2000s. Short-term perturbations significantly impact its mass balance on decadal scales. Utilising a long-term data record going back to 1900 together with the Ice-sheet...
