Abstract:
We present paleomagnetic data (inclination, declination, relative paleointensity) of marine sediment core DA17-NG-ST03-039G collected on the North East Greenland Shelf during the NorthGreen2017 Expedition in September 2017. The core was subsampled using u-channels. NRM, ARM, IRM and SIRM were measured using a 2G Enterprises 755SRM‐1.65 cryogenic magnetometer. The Mazaud (2005) Excel routine was used to calculate the ChRM (20-60 mT demagnetization steps). RPI profiles were constructed following the slope method and using ARM as a normalizer. The age model is slightly updated from the previous publication Hansen et al., 2022.
