   Abstract : The sediment Core SWERUS-L2-2-PC1 (2PC) retrieved from the Chukchi Sea, Arctic Ocean sits in an oceanographically dynamic location at the Arctic-Pacific Ocean gateway. The 8.3 m-long core was retrieved in Herald Canyon at the marginal ice zone at 57 m depth. READ MORE

3. 2. Palaeomagnetism and Magnetic Fabrics of The Lake Natron Escarpment Volcano-sedimentary Sequence, Northern Tanzania

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Gülsinem Polat Wiers; [2019]
   Keywords : Natron Escarpment; Northern Tanzania; Paleomagnetism; Geomagnetic Polarity Time Scale; Anisotropy of Magnetic Susceptibility;

   Abstract : The East African Rift System diverges in the Lake Natron Basin of Northern Tanzania and is a major zone of continental extension and crustal thinning with resulting in active tectonics and volcanism. The discovery of Acheulean technology in Olduvai Gorge and Peninj as well as the presence of significant volcanic centers, has made in the region subject to studies in various disciplines. READ MORE

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

   University essay from Lunds universitet/Geologiska institutionen

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

   Abstract : 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.

5. 4. 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 institutionen

   Author : Andreas Nilsson; [2006]
   Keywords : Palaeomagnetism; Holocene varved lake sediments; varve chronology; geomagnetic models; Holocena varviga sjösediment; varvkronologi; geomagnetiska modeller; Earth and Environmental Sciences;

   Abstract : 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
