Comparing different machine‐learning techniques to date Nile Delta sediments based on portable X‐ray fluorescence data

open access: yesGeoarchaeology, Volume 38, Issue 1, Page 57-75, January/February 2023., 2023
Abstract Geomorphology generally aims to describe and investigate the processes that lead to the formation of landscapes, while geochronology is needed to detect their timing and duration. Due to restrictions on exporting geological samples from Egypt, modern geoscientific studies in the Nile Delta lack the possibility of dating the investigated ...

Géomorphologie : géographie globale – géographie totale – associations internationales [PDF]

open access: yes, 1964
The great advances that geomorphology has made in recent years make necessary a critical re-examination of the relationships between this science and the field of geography. Is geomorphology truly geographical ?

Spatial variation of grassland canopy affects soil wetting patterns and preferential flow

open access: yesHydrological Processes, Volume 36, Issue 12, December 2022., 2022
Spatially heterogeneous canopy and pre‐event soil moisture conditions changed soil‐wetting patterns. Taller grass, together with drier soil, weakens soil moisture response, probably because of uneven water input and dryness induced preferential flow. Abstract Canopies shape net precipitation patterns, which are spatially heterogeneous and control soil ...

Eco-evolution from deep time to contemporary dynamics: the role of timescales and rate modulators [PDF]

open access: yesarXiv, 2022
Eco-evolutionary dynamics, or eco-evolution for short, are thought to involve rapid demography (ecology) and equally rapid phenotypic changes (evolution) leading to novel, emergent system behaviours. This focus on contemporary dynamics is likely due to accumulating evidence for rapid evolution, from classical laboratory microcosms and natural ...

Quantifying and analyzing rock trait distributions of rocky fault scarps using deep learning approach [PDF]

open access: yes, 2022
We apply a deep learning model to segment and identify rock characteristics based on a Structure-from-Motion orthomap and digital elevation model of a rocky fault scarp in the Volcanic Tablelands, eastern California. By post-processing the deep learning results, we build a semantic rock map and analyze rock trait distributions.

The glacial geomorphology of western Dronning Maud Land, Antarctica

open access: yesJournal of Maps, 2020
Reconstructing the response of present-day ice sheets to past global climate change is important for constraining and refining the numerical models which forecast future contributions of these ice sheets to sea-level change.

Long-Term Dynamics of Land Use in the Romanian Plain—The Central Bărăgan, Romania

open access: yesAgriculture, 2021
Changes in land use and agricultural landscapes are primarily the result of socio-political and economic changes. This research is based on the analysis of old maps, pertaining to different historical periods, aiming to capture the dynamics of the ...

Deep Learning Eliminates Massive Dust Storms from Images of Tianwen-1 [PDF]

open access: yesarXiv, 2022
Dust storms may remarkably degrade the imaging quality of Martian orbiters and delay the progress of mapping the global topography and geomorphology. To address this issue, this paper presents an approach that reuses the image dehazing knowledge obtained on Earth to resolve the dust-removal problem on Mars.
