Does Eolian Flux to the Northwest Pacific Ocean Reflect Persistent Asian Interior Aridity on Orbital Timescales?

open access: yesGeophysical Research Letters, Volume 52, Issue 2, 28 January 2025.
Abstract Northwest Pacific sedimentary eolian dust flux records have long been used to make direct inferences about Asian interior aridity. However, factors other than aridity can impact dust production rate. We present here an integrated environmental magnetic, electron microscopic, sedimentologic, and geochemical investigation of eolian dust records ...
