The Influence of Orbital Forcing on 10Be Deposition in Greenland Over the Glacial Period

Understanding the transport and deposition of cosmogenic isotope 10 Be is vital for application data to infer past changes solar activity, reconstruct Earth’s magnetic field intensity climate change. Here, we use from Greenland ice cores, namely NEEM GRIP identify factors controlling its distribution. After removing effects geomagnetic on radionuclide production rate, results expose imprints 20–22 ka precession cycle records last glacial period. This finding can further improve understanding variability in sheets has prospect providing better reconstructions activity based records.
