  1. 1. Odensjön - A new varved lake sediment record from southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Hanna Hertzman; [2021]
    Nyckelord :Varved lake sediment; late Holocene; organic sediments; diatoms; land-use history; southern Sweden; palaeolimnology; Earth and Environmental Sciences;

    Sammanfattning : Annually laminated (varved) sediments provide opportunities to reconstruct climate change and human impact on the environment with high temporal resolution. Depending on the character of the varves, such sediments can provide insight into the delivery of both autochthonous and allochthonous material from the lake and its catch- ment and answer questions regarding both regional and local responses to climate- and land-use changes.

  3. 2. Holocene lake-level changes in the Siljan Lake District – Towards validation of von Post’s drainage scenario

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Savvas Paradeisis-Stathis; [2020]
    Nyckelord :Lake Siljan; Dalarna; basin isolation; catastrophic drainage; early Holocene; lake sediments; XRF scanning; C N ratio; magnetic susceptibility; pollen; Ancylus Lake; Earth and Environmental Sciences;

    Sammanfattning : The Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. LÄS MER

  4. 3. Environmental change during the Holocene : A comparative multi-proxy study of landscape disturbances in Northern Sweden

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Mégane Capel; [2019]
    Nyckelord :Holocene; Lake-Water TOC; climate; lake sediment; vegetation;

    Sammanfattning : Varved lake sediments were used to provide information on how a landscape is affected by disturbances of different scales, from global (i.e. climatic) to local (i.e. LÄS MER

  5. 4. Impact of southern Baltic sea-level changes on landscape development in the Verkeån River valley at Haväng, southern Sweden, during the early and mid Holocene

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Anette Nilsson Brunlid; [2018]
    Nyckelord :sea-level change; Littorina Sea; Baltic Sea; Ancylus Lake; environmental reconstruction; Holocene; Earth and Environmental Sciences;

    Sammanfattning : In the Hanö bay off the coast at Haväng in SE Scania, southern Sweden, a submerged and well-preserved Mesolithic landscape is found, including remains of trees, river and lagoon sediments, and archaeological artefacts such as an antler pick axe and stationary fishing constructions. The landscape was formed during the Yoldia Sea (11,700-10,800 cal BP) and Initial Littorina Sea (9800-8500) low-water phases of the Baltic Basin. LÄS MER

  7. 5. Sedimentology and Catchment Processes of Lake Bolterskaret, Svalbard

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

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

    Sammanfattning : 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. LÄS MER
