Industrial Gamma Radiation Signals: An Untapped Resource to Reconstruct Neogene Paleoclimate Off Northwest Australia

Paleoceanography and Paleoclimatology, Volume 40, Issue 9, September 2025.
Abstract Paleoceanographic reconstructions require both high‐resolution temporal records and high‐density spatial coverage. Scientific drilling provides detailed paleoclimate time‐series, but its spatial distribution limits our ability to capture regional climate dynamics.
