  1. 1. Arctica Islandica – Annually Banded Mollusc Offers High Temporal Resolution Record Into End Of North Sea Little Ice Age

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Eilidh Towers; [2022]
    Nyckelord :sclerochronology; Arctica islandica; palaeoenvironments; Little Ice Age; radiocarbon reservoir effect;

    Sammanfattning : Sclerochronology affirms the well-established fact that banded growth increments in marine molluscs accurately record oscillations in climate and environment for the past millennia or more. This study considers how such records can enhance understanding of environmental shifts across the 18th to 20th centuries. LÄS MER

  2. 2. Klimat och väder i Nordatlanten-regionen under det senaste årtusendet

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Linus Brakebusch; [2020]
    Nyckelord :Solar activity; Volcanic activity; North Atlantic Oscillation NAO ; Medieval Warm Period; Little Ice Age; Earth and Environmental Sciences;

    Sammanfattning : One of the most important areas in climatology today is the development of climate models. To evaluate how well a particular climate model is working it is compared with climate reconstructions based on proxy-data, which is indirect climate information that can be obtained from climate archives.

  3. 3. Icelandic Glacial Ice Volume Changes and its Contribution to Sea Level Rise since the Little Ice Age Maximum

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Stephanie Fish; [2016]
    Nyckelord :Iceland; Little Ice Age; sea level rise; volume-area scaling; glaciers; climate change; Island; Lilla istiden; havsnivåhöjning; volym-area skalning; glaciärer; klimatförändringar;

    Sammanfattning : Satellite imagery and volume-area scaling are used to asses the glacier area and ice volume of Iceland from the Little Ice Age maximum to present day, obtaining a final result in sea level rise between 1890 - 2015. The Little Ice Age was a time of regional cooling, with glaciers reaching their maximum extent (~1890 for Iceland) with warming and glacier retreat after this period ended. LÄS MER

  4. 4. Volymändringar i Sareks och Kebnekaises glaciärer sedan lilla istiden

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Linus Engqvist; [2016]
    Nyckelord :Glaciologi; fjärranalys; volym-areaskalning;

    Sammanfattning : Volume Changes of the Glaciers in Sarek and Kebnekaise since the End of the Little Ice Age Linus Engqvist  Since the end of the little ice age in the middle of the 19th century  the glaciers in the north of Sweden has experienced extensive melting and net loss of volume, but are all glaciers experiencing equal loss of volume or are there differences between them?  The purpose of this study is to examine 53 different glaciers in the Sarek and Kebnekaise regions in the North of Sweden and by using remote sensing techniques calculate the relative volume changes of the glaciers and then examine if there any differences between them with regards to massifs, historical area and ablation zone. The conclusion is that even though there are differences in loss between massif and ablation zone location the most significant factor to relative volume loss is the glaciers original area, but because of the limitations in the study further research is needed to better estimate the volume of the individual glaciers.

  5. 5. Geochemical and palaeomagnetic characteristics of a Swedish Holocene sediment sequence from Lake Storsjön, Jämtland

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Joakim Robygd; [2015]
    Nyckelord :Jämtland; geochemistry; palaeomagnetism; PSV; sedimentation rate; Holocene development; geochronology; climate change; Earth and Environmental Sciences;

    Sammanfattning : As a part of a French-Swedish collaboration project to reconstruct middle to northern European climate variations during the Holocene, a sediment sequence from Lake Storsjön, Jämtland was retrieved and analysed for geochemical and palaeomagnetic properties. The subsampled sequence, composed of one freeze core and three Niederreiter piston cores, revealed information of both climatic, environmental and anthropogenic changes over the past 10,800 years.
