Accurate measurements of the past extent of the Greenland ice sheet are crucial to understand its response to changing climate conditions. Here, the authors present a dust record from an ice core from the east coast of Greenland to provide detailed t

We present the first comprehensive dust provenance and lithogenic flux data set extracted from surface sediments distributed across the polar and subpolar South Pacific. The dataset comprises 230Th-normalized lithogenic fluxes combined with rare eart

The chemical and isotopic compositions of sediments and dust can be used to trace their provenance, providing insights into many Earth surface processes. During past glacial climates, much of the New Zealand (NZ) South Island was blanketed by erosive

Diatoms can access mineral iron from dust if it is reduced, and reduced particulate iron is common in glacial dust sources.
Little is known about the bioavailability of iron (Fe) in natural dusts and the impact of dust mineralogy on Fe utilizati

Reconstructions of the deposition rate of windblown mineral dust in ocean sediments offer an important means of tracking past climate changes and of assessing the radiative and biogeochemical impacts of dust in past climates. Dust flux estimates in o
