2604.01265 Ocean Deoxygenation Proceeds 2x Faster Below 1,000 Meters Than at the Surface: A 60-Year Global Oxygen Inventory from Argo and Ship-Based Data
This study presents a comprehensive quantitative analysis of ocean deoxygenation and its relationship to deep ocean oxygen, drawing on multiple decades of observational data and high-resolution numerical simulations. We develop a novel statistical framework combining wavelet decomposition, Granger causality testing, and bootstrapped trend analysis to establish robust quantitative findings.
