A database of radiogenic Sr–Nd isotopes at the “three poles” [PDF]

open access: yesEarth System Science Data, 2022
The radiogenic isotope compositions of strontium (Sr) and neodymium (Nd) on the surface of the Earth are powerful tools for tracing dust sources and sinks on the Earth's surface.

A Sediment Magnetic Record in the North Pacific Across the Mid-Pleistocene Transition and its Implication on Asian Dust Evolution

open access: yesFrontiers in Earth Science, 2021
Eolian dust deposited in the North Pacific is an important archive of the evolutionary history of Asian interior source regions and climate system. Here, we present a ∼1 Myr sediment magnetic record from the central North Pacific to characterize eolian ...

Vegetation and geochemical responses to Holocene rapid climate change in the Sierra Nevada (southeastern Iberia): the Laguna Hondera record [PDF]

open access: yesClimate of the Past, 2018
High-altitude peat bogs and lacustrine records are very sensitive to climate changes and atmospheric dust input. Recent studies have shown a close relationship between regional climate aridity and enhanced eolian input to lake sediments.

Tracking atmospheric and riverine terrigenous supplies variability during the last glacial and the Holocene in central Mediterranean [PDF]

open access: yesClimate of the Past, 2013
A multiproxy study – coupling mineralogical, grain size and geochemical approaches – was used to tentatively retrace eolian and fluvial contributions to sedimentation in the Sicilian–Tunisian Strait since the last glacial.

Das Problem der Lößbildung und die Lößmollusken [PDF]

open access: yesEiszeitalter und Gegenwart, 1965
At present, the view is generally adopted that loess does not originate only by the accumulation of wind-borne dust, but also by a particular soil-forming process (loessification), that impresses to dust-accumulations typical features of loess ...

Did changes in terrigenous components of deep-sea cherts across the end-Triassic extinction relate to Central Atlantic magmatic province volcanism?

open access: yesFrontiers in Earth Science, 2023
The end-Triassic mass extinction event (ETE) is considered to be linked with the emplacement of the Central Atlantic magmatic province (CAMP), yet their temporal relation and underlying nature of global environmental and biotic changes remain ...

Natural and anthropogenic contributions to the hurricane drought of the 1970s–1980s

open access: yesNature Communications, 2022
Atlantic hurricane numbers noticeably decreased in the 1970s and 1980s partly due to the cooling effect of eolian dust lofted from the Sahara, in response to local climate effects of aerosol pollutants emitted from Europe and North America.

Northward Shift of the Northern Hemisphere Westerlies in the Early to Late Miocene and Its Links to Tibetan Uplift

open access: yesGeophysical Research Letters, 2022
Despite the importance of the westerlies to the global climate system, we still know little about their long‐term evolution and possible orographic controls during the late Cenozoic because of the lack of sedimentary records with precise chronological ...

Major dust events in Europe during marine isotope stage 5 (130–74 ka): a climatic interpretation of the "markers" [PDF]

open access: yesClimate of the Past, 2013
At present, major dust storms are occurring at mid-latitudes in the Middle East and Asia, as well as at low latitudes in Northern Africa and in Australia.

Changes in diffuse reflectance spectroscopy properties of hematite in sediments from the North Pacific Ocean and implications for eolian dust evolution history

open access: yesEarth and Planetary Physics, 2018
Eolian dust preserved in deep-sea sediments of the North Pacific Ocean (NPO) is an important recorder of paleoclimatic and paleoenvironmental changes in the Asian inland.
