Constraining the past geomagnetic field variation is fundamental for several disciplines such as Geophysics, Stratigraphy, Volcanology, Palaeoclimatology, Human history, Archaeology etc. Despite the great effort made in recent years to improve both spatial and temporal coverages of palaeomagnetic data, fundamental properties of the field, such as the average strength and its spatial and temporal (short- and long-term) directional variations over time, remain topics of debate. The inherent difficulties in obtaining well distributed palaeomagnetic records and reliable palaeointensity data are reflected in the current palaeomagnetic databases. Available data are clearly biased toward the last 10 ka and mostly the northern latitudes. Even though, in recent years, our ability in selecting the most reliable data has improved, more data are still needed mostly from underrepresented geographical areas and temporal intervals.
This session welcomes abstracts presenting methodological advances, new directional and palaeointensity data, especially respecting the FAIR data management, as well as new palaeomagnetic reconstructions at local or global scale for a better understanding of the past behaviour of the Earth’s magnetic field. Contributions presenting relative palaeointensities, rock magnetic and micromagnetic investigation applied to address the palaeointensity and paleomagnetic determination issue are also welcome.

How to access EMRP3.6
Session EMRP3.6 runs as a vPICO session. Everybody, conveners/chair/speakers as well as attendees, join the live session page on EGU21. While attendees stay on this live session page and see the live presentations via stream, you as convener/chair/speaker are required to enter the BigBlueButton (BBB) live video chat to give your presentation.
Please keep the live session page open on this browser tab and join the BBB video chat in parallel on another browser tab through the button below. Your personal breakout text chat following the live presentations are linked from the live session page tab, not from the additional BBB video chat tab.Enter BBB video chat
