Field erosion by wind as indicated by fluctuations in the ash content of Sphagnum peat [PDF]

open access: yesBulletin of the Geological Society of Finland, 1983
The ash content curves for three Sphagnum peat profiles were correlated with those for Cerealia and the natural indicators of bare mineral soil. The fluctuations in the ash values seem to indicate erosion of fields by wind as a result of tilling and ...

Our evolving understanding of aeolian bedforms, based on observation of dunes on different worlds [PDF]

open access: yes, 2016
Dunes, dune fields, and ripples are unique and useful records of the interaction between wind and granular materials – finding such features on a planetary surface immediately suggests certain information about climate and surface conditions (at least ...

Stepwise Weakening of Aeolian Activities During the Holocene in the Gannan Region, Eastern Tibetan Plateau

open access: yesFrontiers in Earth Science, 2021
Aeolian sediments hold key information on aeolian history and past environmental changes. Aeolian desertification and extensive land degradation have seriously affected the eco-environment in the Gannan region on the eastern Tibetan Plateau ...

Human activity and aeolian relief of Starczynów “Desert”, Poland [PDF]

open access: yes, 2013
Starczynów „Desert” is located in the eastern part of the Silesian Upland (southern Poland) and makes a compact area with the occurrence of aeolian sands, which till the 1960s. were intensively blown.

The north-eastern aeolian 'European Sand Belt' as potential record of environmental changes: A case study from Eastern Latvia and Southern Estonia [PDF]

open access: yes, 2016
The Latvian and Estonian inland dunes belong to the north-eastern part of the 'European Sand Belt' (ESB). These dunes are widely distributed over broad glaciolacustrine plains and Late Glacial alluvial deltas, considered to be potential sources for the ...

Reconstruction of linear dunes from ancient aeolian successions using subsurface data: Permian Auk Formation, Central North Sea, UK [PDF]

open access: yes, 2018
A series of well logs and cores penetrating the predominantly aeolian Auk Formation, Permian Rotliegend Group, Central North Sea, UK, have been evaluated to determine the morphology and style of migratory behaviour of the original dune bedforms, the ...

Dark aeolian sediments in Martian craters: Composition and sources [PDF]

open access: yes, 2011
Our research focuses on the mineralogical characteristics of dark sediment deposits in Martian craters (dunes, dune fields, and sand sheets) and their local sediment sources, carried out on the basis of 70 selected localities.

Migrating meter-scale bedforms on Martian dark dunes: Are terrestrial aeolian ripples good analogues? [PDF]

open access: yes, 2017
Using automatic bedform mapping, principal component analysis and clustering we present a multiscale morphodynamic survey of dunes and meter-scale ripples on Herschel crater, Mars.

Linked fluvial and aeolian processes fertilize Australian bioregions

open access: yes, 2015
The pattern of 137Cs-derived net (1950s–1990) soil redistribution over Australia, together with back-trajectory modeling of major dust storms, shows extensive areas of contemporary aeolian deposition.

Planetary Aeolian Geomorphology

open access: yes, 2019
Aeolian processes contribute to surface landforms on several bodies in our solar system. Sediment transport is responsible for a broad range of geophysical phenomena, including dust storms on Earth and Mars and the formation and migration of dunes on ...
