  1. 1. 231Pa, 230Th and 232Th as tracers of deep water circulation and particle transport : Insights from the Mediterranean Sea and the Arctic Ocean

    Författare :Sandra Gdaniec; Carl Magnus Mörth; Matthieu Roy-Barman; Per Andersson; Laura Robinson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; protactinium; thorium; Mediterranean Sea; Arctic Ocean; scavenging; marine particles; boundary scavenging; particle transport; geotraces; maringeologi; Marine Geology;

    Sammanfattning : The naturally occurring U and Th-series radionuclides have shown to have a considerable importance for the understanding of biogeochemical processes on Earth and in the ocean. In this thesis, the isotopes 230-thorium (230Th), 232-thorium (232Th) and 231-protactinium (231Pa) are used as tracers of the transport and scavenging of marine particles and water circulation.

  2. 2. Affective Borderscapes : Constructing, Enacting and Contesting Borders across the Southeastern Mediterranean

    Författare :Ioanna Wagner Tsoni; James W. Scott; Malmö universitet; []
    Nyckelord :Migration; Affect; Borders; Borderscapes; Mediterranean; Greece; Aegean Sea; Lesvos; Refugees;

    Sammanfattning : In the wake of a sociopolitically volatile era, which is increasingly characterized by the intensive and extensive proliferation of borders, the management of borders and migration are considered as predominantly rational and dispassionate processes. Their functions and filtering mechanisms, however, are increasingly underpinned by the instrumental top-down exertion of affective power and by the cultivation of emotional dispositions among political communities.

  4. 4. 231Pa and Th isotopes as tracers of deep water ventilation and scavenging in the Mediterranean Sea

    Författare :Sandra Gdaniec; Carl-MAgnus Mörth; Per Andersson; Helen Coxall; Per Roos; Per Anerson; Matthieu Roy-Barman; Carl-Magnus Mörth; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 231Pa; 230Th; 232Th; Mediterranean Sea; scavenging; deep water ventilation; geokemi; Geochemistry; Protactinium; Thorium; particle transport; deep water circulation;

    Sammanfattning : The naturally occurring isotopes 231Pa and 230Th are used as tracers of marine biogeochemical processes. They are both produced from the radioactive decay of their uniformly distributed uranium parents (235U and 234U) in seawater. LÄS MER

  5. 5. European Mobility and Spatial Belongings : Greek and Latvian migrants in Sweden

    Författare :Vasileios Petrogiannis; Karin Borevi; Norbert Götz; Jussi Kurunmäki; Peo Hansen; Södertörns högskola; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; migration; intra-European migration; European mobility; national identity; European identity; regional identity; belonging; macro-regions; Baltic Sea; Mediterranean; Latvia; Greece; Sweden; migration; intra-europeisk migration; europeisk mobilitet; nationell identitet; europeisk identitet; regional identitet; tillhörighet; makro-regioner; Östersjön; Medelhavet; Lettland; Grekland; Sverige; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Nation-states and national identities are a product of European history and have been the most salient framework of spatial identification since the nineteenth century. In the past decades, however, the EU has attempted to foster a supplementary European sense of identity, embodied in the notion of European citizenship. LÄS MER
