  1. 16. Tackling the Eyjafjallajökull Volcanic Ash Crisis: How the EU influenced the International Civil Aviation Organization

    University essay from Lunds universitet/Statsvetenskapliga institutionen

    Author : Karolina Krystyniak; [2011]
    Keywords : European Union; ICAO; Volcanic Ash Crisis; Institutional Interaction; Aviation; Law and Political Science;

    Abstract : The goal of this single-case study is to contribute to understanding of the Eyjafjallajökull volcanic ash crisis from the institutional perspective. The Eyjafjallajökull eruption in April 2010 and the subsequent volcanic ash crisis grounding the flights across Europe demonstrated certain procedural inadequacies in the international aviation regime.

  3. 17. Constraining Crustal Volatile Release in Magmatic Conduits by Synchrotron X-ray μ-CT

    University essay from Berggrundsgeologi

    Author : Sylvia Berg; [2011]
    Keywords : xenoliths; crustal gases; synchrotron X-ray μ-CT; 3D-bubble networks; gas migration; magmatic volatile budget; explosive eruption;

    Abstract : Magma-crust interaction in magma reservoirs and conduits is a crucial process during magma evolution and ascent. This interaction is recorded by crustal xenoliths that frequently show partial melting, inflation and disintegration textures. READ MORE

  4. 18. Probing the Toba super-eruption: Insights from oxygen isotope geochemistry and geobarometry

    University essay from Berggrundsgeologi

    Author : David Budd; [2011]
    Keywords : super-eruption; oxygen isotopes; geobarometry; Toba; magmatic plumbing; caldera;

    Abstract : The Toba caldera located in north Sumatra, Indonesia, is the source of the largest volcanic eruption in the Quaternary (Rose & Chesner 1987). Its enormous volume of 2800 km3 has been a matter of debate for decades and it is still unclear where and how the Toba magma was assembled. READ MORE

  5. 19. Disintegration and Devolatilisation of Sandstone Xenolith in Magmatic Conduits: an Experimental Approach

    University essay from Berggrundsgeologi

    Author : Sylvia Berg; [2010]
    Keywords : xenolith; melting; bubbles; gas migration; crustal volatiles; magma-crust interaction; magma volatile budget; explosive eruption;

    Abstract : Xenoliths preserve evidence of magma-crust interactions in magmatic reservoirs and conduits. They reveal processes of partial melting of country rock, and disintegration into magma. Widespread evidence for frothy xenoliths in volcanic deposits exists, and these evidently indicate processes of gas liberation, bubble nucleation and bubble growth. READ MORE

  6. 20. A Greenland ice core perspective on the dating of the Late Bronze Age Santorini eruption

    University essay from Lunds universitet/Geologiska institutionen

    Author : Elin Löfroth; [2010]
    Keywords : Santorini; 10Be; 14C; NGRIP; kolcykelmodellering; carbon cycle modeling; Earth and Environmental Sciences;

    Abstract : The Santorini eruption is one of the greatest in historic time and an important time marker in the regional archaeology. It has been dated to 1627-1600 BC (2σ error) using radiocarbon dating (Friedrich et al. 2006) and to 1642±5 BC by identifying a volcanic fallout layer in the Greenland ice cores (Vinther et al. 2006).
