PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.971851 (dataset in review)
Abstract:
This paleomagnetic stack was built using cores AMD1902-10GC (data available in PANGAEA, Girard et al., 2024), cores OD1507-04GC, OD1507-41GC, OD1507-40TC (data available in MagIc, Reilly et al., 2019). The stack was calculated as follow: Bin widths of 5 cm CED were used to calculate the Fisher mean of the directions with N the number of cores contributing to the stack for each calculation. The virtual geomagnetic pole (VGP) coordinates were calculated assuming stack declination rotation of 125 degrees +/- 20 degrees.
