  1. 1. Glacial history of the upper Drac Blanc catchment (French Alps)

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Felix Martin Hofmann; [2018]
    Keywords : Physical Geography; 10Be exposure dating; structure-from motion; geomorphological mapping; moraine; equilibrium line altitude; Alps; Earth and Environmental Sciences;

    Abstract : Glacier advances in the Écrins massif (French Alps) during the Late Glacial and the Early Holocene are poorly constrained. Based on field observations, a high-resolution digital elevation model and an orthophoto, glacial landforms in the upper Drac Blanc catchment were mapped. READ MORE

  3. 2. Multiradionuclide evidence for an extreme solar proton event around 2610 BP

    University essay from Lunds universitet/Geologiska institutionen

    Author : Martin Paschal Ohare; [2017]
    Keywords : cosmic-rays; cosmogenic radionuclides; NGRIP; GRIP; solar proton event; SPE; Earth and Environmental Sciences;

    Abstract : Recently it has been confirmed that extreme solar proton events (SPE) can lead to significantly increased production of cosmogenic radionuclides (Mekhaldi et al. 2015). The evidence of these events can be recorded in tree rings (14C) and ice cores (10Be, 36Cl). READ MORE

  4. 3. The dynamics of Beryllium 10 transport and deposition in lake sediments

    University essay from Lunds universitet/Geologiska institutionen

    Author : Oskar Henriksson; [2016]
    Keywords : solar activity; Beryllium-10; lake sediment; 10Be; solar cycle; Earth and Environmental Sciences;

    Abstract : Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. READ MORE

  5. 4. The cosmic-ray events around AD 775 and AD 993 : assessing their causes and possible effects on climate

    University essay from Lunds universitet/Geologiska institutionen

    Author : Florian Mekhaldi; [2014]
    Keywords : cosmic-rays; cosmogenic radionuclides; GICC05; NGRIP; solar proton event; storminess; Earth and Environmental Sciences;

    Abstract : Miyake et al. (2012, 2013) discovered rapid increases of 14C content in tree rings dated to AD 774-5 and AD 992-3 which were attributed to unprecedented cosmic-ray events. These extreme particle events have no counterparts in the instrumental and historical record and consequently praised great interest. READ MORE

  6. 5. 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).
