This report is made for ICAO and the Icelandic Met Office, financed partly by ICAO. Total grain size distribution in explosive volcanic eruptions reports quantitative distribution of all grain that are formed in that eruption. When modelling distribution of volcanic ash in the atmosphere one of most important factor is the quantitative grain size distribution in the whole deposits formed. Fine ash grains (ash) do go further away from the volcano than do the coarse (lapilli).
Speaker: Dr. Johanne Schmith
Name of thesis: Volcanology and hazards of phreatomagmatic basaltic eruptions
Adviser: Ármann Höskuldsson, Research Scientist at the Earth Science Institute at the University of Iceland.
Doctoral committee: Paul Martin Holm, Associate Professor at the University of Copenhagen.
This is a joint degree with the University of Copenhagen. The defense has already been delivered.
Sigurður Reynir Gíslason, research professor at the Institute of Earth Sciences, University of Iceland, will receive the 2018 Clair C. Patterson Award this summer. The Patterson Award is granted by The Geochemical Society and recognizes an innovative breakthrough of fundamental significance in environmental geochemistry, particularly in service of society, consisting of either a single outstanding contribution or a short series of papers published within the last decade.
On Wednesday March 7th, Stefán Arnórsson, professor emeritus in the Faculty of Earth Sciences, will give a lecture on progressive water-rock interaction of surface- and up to 100°C ground-water in the Skagafjördur Province, N-Iceland.
The subject of the lecture is partly based on a newly published book, yet more detailed, by the speaker (chapter 6), entitled Jarðhiti og jarðarauðlindir (geothermal energy and Earth´s resources). The lecture will be given in English.
Venue: Lecture Hall N-132, ground floor in Askja
A prediction model that better enables research scientists to compute the future melt of glaciers; taking climate change into account, is the result of a three year research project conducted by research scientist at the Institute of Earth Sciences in collaboration with domestic and international institutes and companies. The model will also prove useful to the Icelandic National Power Company (Landsvirkjun) for planning hydropower production, and furthermore for issuing flood warnings.
