1. Odensjön - A new varved lake sediment record from southern Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : 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.

2. Environmental change during the Holocene : A comparative multi-proxy study of landscape disturbances in Northern Sweden
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : 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. READ MORE

3. Sedimentology and Catchment Processes of Lake Bolterskaret, Svalbard
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : 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. READ MORE

4. Testing the hypothesis of a link between Earth’s magnetic field and climate change : a case study from southern Sweden focusing on the 1st millennium BC
University essay from Lunds universitet/Geologiska institutionenAbstract : It is commonly believed that long-term (10 to 1000 kyr) and short-term (10 to 1000 years) climatic changes on Earth can be interpreted by periodic variations in Earth’s orbit around the Sun and variations in solar irradiance, respectively. In recent years, geomagnetic field changes have been suggested as a potential driver of climate change. READ MORE

5. Palaeomagnetic secular variations in the varved sediments of lake Gościąż, Poland : testing the stability of the natural remanent magnetization and validity of relative palaeointensity estimates
University essay from Lunds universitet/Geologiska institutionenAbstract : Fyra två meter långa borrkärnor, med sjösediment från Gościąż, Polen, analyserades med hjälp av den s.k. Pseudo-Thellier metoden, en metod som används för att utvärdera tillförlitligheten av variationer av styrkan i det jordmagnetiska (palaeointensiteten) fältet över tiden. READ MORE
