  1. 16. Central Asian ice-marginal moraines of the global last glacial maximum : An analysis of topographic features affecting the glaciation pattern in the Tian Shan and Altai mountains

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Sonja Sandström; [2018]
    Keywords : Altaimountains; GeographicInformation System; Tian Shan mountains; water resources; marginal moraine; MIS 2; paleoglaciology;

    Abstract : Glacial runoff from the Tian Shan and Altai Mountains is an important water resource, especially for people living in the arid areas of Central Asia. Measured water volumes from glaciers have decreased, and glacier area have shrunk with 50-90% since the Little Ice Age. READ MORE

  3. 17. Estimation of Relative Seismic Velocity Changes Around Katla Volcano, Using Coda in Ambient Seismic Noise

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frida Jonsdottir; [2018]
    Keywords : Katla volcano; Iceland; ambient seismic noise; coda waves; relative velocity variations; Katla vulkan; Island; omgivande seismiskt brus; codavågor; relativa hastighetsvariationer;

    Abstract : Relative seismic velocity variations in the Earth’s crust can be estimated by using ambient seismic noise records from a pair of stations. Velocity variations can be caused by stress perturbations in the subsurface. Therefore, information on stress changes in the crust can possibly be retrieved from measured velocity variations in the medium. READ MORE

  4. 18. Sedimentology and Catchment Processes of Lake Bolterskaret, Svalbard

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Matilda Elise Ruth Svensson; [2018]
    Keywords : Lacustrine sedimentation; Bolterskaret; late Holocene; Climate change; Varves;

    Abstract : Lacustrine sediments are important archives of landscape and climate evolution. Varved sediments offer a high-resolution archive enabling studies on annual and seasonal scale. Understanding the alteration of sedimentation in glacial lakes under a changing climate is important for paleoclimate reconstructions. READ MORE

  5. 19. The behaviour of melt water within a glacial system

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Love Tingdal; Nils Ceder; [2017]
    Keywords : meltwater; percolation; ice lens; glacier; smältvatten; perkolation; islins; glaciär;

    Abstract : A glacier contains of many different layers of different properties. Each layer is formed during a calendar year similar to tree rings and their layers. A glacier has two different zones, the first one referred to as accumulation zone, where the addition of snow exceeds the loss of snow. READ MORE

  6. 20. Conditional cooperation for mitigating effects of climate change in rural Nepal

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Björn Synneby; [2016-11-16]
    Keywords : ;

    Abstract : Due to the climate warming effects the glacier lakes of the Khumbu has started to form and grow in size and the natural moraine dams give poor support to the expanding lakes. In order to find out how much the sherpa people wants to contribute to build the safety measures that can protect them from the effects of a glacier lake outburst flood this paper investigates their willingness to contribute with work time.
