Quaternary stratigraphy and climatic changes
Saturday 7 November 2015
Part of the research conducted in the laboratory is aimed at establishing the Quaternary stratigraphy of marine and lacustrine sedimentary sequences from both hemispheres: Eastern Canada, the Arctic and Patagonia. This work is based on high-resolution magnetostratigraphy, but also on the (…)
Sedimentary processes and natural hazards
Saturday 7 November 2015
An important part of the research performed at the laboratory employs geophysical methods and detailed sediment core analysis to investigate the sedimentary processes of several marine and lacustrine areas around the globe. The research is also aimed at identifying, distinguishing and dating (…)
Geomagnetic field dynamics
Saturday 7 November 2015
An important part of the research conducted in the laboratory is aimed at reconstructing secular and millennial scale variations of Earth’s magnetic field during the Quaternary from marine and lacustrine sediment cores collected in Eastern Canada, the Arctic, Antarctica, Asia and the Southern (…)
