2. 1. Contaminated organic sediments of anthropogenic origin: impact on coastal environments

   Author : Anna Apler; Ian Snowball; Sarah Josefsson; Lovisa Zillén; Magdalena Kuchler; Jonas Gunnarsson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiberbank; fiber-rich sediment; metals; persistent organic pollutants; pore water; bottom water; dispersal; sorption; pulp and paper; chemostratigraphy; Anthropocene; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

   Abstract : The Baltic Sea is negatively affected by legacy pollutants such as metals and persistent organic pollutants (POPs) that are known to have adverse effects on living organisms, including, humans and were banned decades ago. This thesis addresses the dispersal of these pollutants from heavily contaminated, cellulose-rich sediments of industrial origin in the Ångermanälven river estuary in northern Sweden. READ MORE

4. 2. Dispersal and environmental impact of contaminants in organic rich, fibrous sediments of industrial origin in the Baltic Sea

   Author : Anna Apler; Ian Snowball; Karin Wiberg; Kevin Bishop; Sarah Josefsson; Lovisa Zillén; Ida-Maja Hassellöv; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fiberbank; fiber-rich sediments; metals; persistent organic pollutants; pore water; bottom water; dispersal; sorption; pulp and paper; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

   Abstract : The health of the Baltic Sea is negatively affected by hazardous substances such as metals and persistent organic pollutants (POPs), which include legacy pollutants that were banned decades ago, but still circulate in the ecosystem. Elevated levels of legacy pollutants, identified by HELCOM as key hazardous substances, have been found in accumulations of fibrous sediments, so-called fiberbanks and fiber-rich sediments, which derive from old pulp mills along the Swedish north coast.

5. 3. Past environment and sediment dynamics in the Black Sea-Caspian Sea region from Southern Russian loess sequences

   Author : Chiara Amalia Költringer; Thomas Stevens; Bjarne Almqvist; Ian Snowball; Kathryn Fitzsimmons; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Loess deposits are excellent past climate and environment archives and contain records of aeolian mineral dust accumulation. Loess deposits stretch across Eurasia and sequences along the Lower Volga in the Northern Caspian lowland in the South East European Plain represent a key link between European and Asian loess.

6. 4. Multidisciplinary Near-Surface Investigation of a Quick-Clay Landslide Prone Area in Southwest Sweden

   Author : Silvia Salas Romero; Alireza Malehmir; Ian Snowball; Christopher Juhlin; Laura Valentina Socco; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quick-clay; reflection seismic; landslide; southwest Sweden; borehole logging; physico-chemical properties; hydrogeological modelling; multichannel analysis of surface waves; magnetics; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Abstract : Quick-clay landslides are considered one of the most important geohazards in Sweden, Norway, and Canada. The deposits involved are glacial and postglacial clays and silty clays, which are very sensitive to increased stress that may collapse their structure and cause liquefaction. READ MORE

7. 5. The Arctic Ocean Palaeomagnetic Record : A Stratigraphic Approach

   Author : Steffen Wiers; Ian Snowball; Bjarne Almqvist; Matt O'Regan; Conall Mac Niocaill; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean; Stratigraphy; Diagenesis; Palaeomagnetism;

   Abstract : The Arctic Ocean is an essential component of the global climate system, yet understanding of its geological archives is hampered by difficulties in age modelling. In addition to the scarcity of dateable microfossils, the palaeomagnetic record of Arctic sediments is unusual. READ MORE
