  1. 21. Comparison between two sediment X-ray Fluorescence records of the Late Holocene from Disko Bugt, West Greenland : paleoclimatic and methodological implications,

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Oskar Jäckel; [2009]
    Nyckelord :Disko Bugt; X-ray fluorescence; mineral magnetism; magnetic susceptibility; paleomagnetism; bromine; productivity; Medieval Warm Period; Earth and Environmental Sciences;

    Sammanfattning : Popular summary: X-raying the climate archive of Disko Bugt. Disko Bugt is a large bay in West Greenland north of the Arctic Circle. Because of the influence of the relatively warm ocean current coming from the south; the West Greenland Current, it has a mild climate despite its latitude. LÄS MER

  3. 22. Stratigraphic studies of the Taniente Palet bog at the north-western corner of Isla de los Estados Tierra del Fuego, South America

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Anna-Kari Trondman; [2007]
    Nyckelord :Holocene; South America; Tierra del Fuego; peat; paleoclimate; holocen; Sydamerika; torv; paleoklimat; Earth and Environmental Sciences;

    Sammanfattning : Fourteen somewhat overlapping 1-m cores, forming a total sequence of about 10.90 metres, were retrieved from Taniente Palet bog on Isla de los Estados, Argentina. The cores were described and correlated both visually and by measuring magnetic susceptibility and loss on ignition. Twelve samples were also taken for radiocarbon dating. LÄS MER

  4. 23. A palaeoecological study of Holocene lake sediments above the highest shoreline in the province of Västerbotten, northeast Sweden

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Petra Bragée; [2005]
    Nyckelord :geography; geology; palaeoecology; Holocene lake sediments; Västerbotten; Sweden; Earth and Environmental Sciences;

    Sammanfattning : En sedimentborrkärna från sjön Svartkälstjärn, belägen 260 m ö.h. nära Vindeln i Västerbotten, provtogs for analys av frekvensen pollen, sporer och kolpartiklar samt beräkning av ackumulationshalter. LÄS MER

  5. 24. A comparative study between loss on ignition and total carbon analysis on Late Glacial sediments from Atteköps mosse, southwestern Sweden, and their tentative correlation with the GRIP event stratigraphy

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Daniel-Stefan Veres; [2001]
    Nyckelord :Atteköps mosse; limnic sediments; Late Glacial; loss on ignition; total carbon; Earth and Environmental Sciences;

    Sammanfattning : Popular abstract: In this study, several sediment core from Atteköps mosse, southwestern Sweden, were investigated with respect to lithostratigraphy, loss on ignition analysis, grain size distribution, magnetic susceptibility, total carbon analysis and 14C dating. The first part of the study foccuses on a detailed analysis of the above mentioned sediment parameters. LÄS MER

  7. 25. A paleoecological study of the Pleistocene-Holocene transition in the Kap Farvel area, South Greenland

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Karl Ljung; [2001]
    Nyckelord :lake sediments; South Greenland; Kap Farvel; Younger Dryas; Preboreal; pollen; plant succession; climate change; Earth and Environmental Sciences;

    Sammanfattning : Populärvetenskaplig sammanfattning: En paleoekologisk studie av övergången från sen- till postglacial tid i Kap Farvel-området, Sydgrönland. En sedimentsekvens från en sjö på Grönlands sydspets, Kap Farvel-området, undersöktes med avseende på polleninnehåll, magnetisk susceptibilitet och organisk halt. LÄS MER
