  1. 11. Mercury in Fossil Leaves as a Proxy for Tracking Large Igneous Province Volcanism

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Johan Näslund; [2021]
    Keywords : ;

    Abstract : During some mass extinctions, usually minor, world oceans also underwent anoxic to euxinic conditions, events called Oceanic anoxic events (OAEs). Such an event unfolded during the Toarcian (∼183 Ma), called the T-OAE which is suggested to have been caused by Karoo-Ferrar Large Igneous Province (LIP) volcanism. READ MORE

    Abstract : Aeolian dust is an important but poorly understood component of the climate system, which both responds to and drives global climate. Recently, dust produced at the high latitudes is also gaining attention as a possible contributor to the atmospheric dust load. READ MORE

  4. 13. A Chronology for a Massacre : Bayesian C-14 Analysis of the Archaeological Record from Sandby Borg, Öland

    University essay from Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)

    Author : Martin Lindahl; [2020]
    Keywords : Radicarbon dating; C-14; Bayesian analysis; OxCal; Sandby borg; Iron age; Öland;

    Abstract : This thesis addresses radiocarbon (C-14) dating of bioarcheological finds from Sandby borg, an iron-age ring fort on the east coast of the Baltic Sea island of Öland, Sweden. Archaeological evidence suggests that Sandby borg was used during the European migration period and that its main period of usage was terminated by an isolated incidence of inter-personal violence where the inhabitants were killed or abducted.

  5. 14. Stratigraphy and dating of a lake sediment record from Lyngsjön, eastern Scania : human impact and aeolian sand deposition during the last millennium

    University essay from Lunds universitet/Geologiska institutionen

    Author : Marijana Stevic; [2019]
    Keywords : aeolian activity; human impact; geochemistry; lake sediments; pollen; Earth and Environmental Sciences;

    Abstract : A small lake in north-eastern Scania, southern Sweden, Lake Lyngsjön, reveals a long history of aeolian sand drift based on a 3 meter long sediment sequence covering the last approximately 1400 years. Human impact, primarily through intensified land use and decreased forest cover, has periodically led to increased aeolian sand drift both locally and regionally. READ MORE

  6. 15. Bits & Bobs : Finds from a research excavation of Birka’s rampart: A study with focus on material distribution and metal conservation

    University essay from Stockholms universitet/Arkeologiska forskningslaboratoriet
