Abstract. Mineral dust plays an important role in the climate system by interacting with radiation, clouds, and biogeochemical cycles. In addition, natural archives show that cycle experienced variability past response to global local change. The compilation of DIRTMAP (Dust Indicators Records from Terrestrial MArine Palaeoenvironments) paleodust data sets last 2 decades provided a benchmark for paleoclimate models include cycle, following time slice approach. We propose innovative framework...
Abstract Changing climate conditions affect dust emissions and the global cycle, which in turn affects biogeochemistry. In this study we use observationally constrained model reconstructions of cycle since Last Glacial Maximum, combined with different simplified assumptions atmospheric sea ice processing dust‐borne iron, to provide estimates soluble iron deposition oceans. For conditions, discuss uncertainties model‐based key oceanic regions, highlighting large degree uncertainty important...

Abstract In this paper we present a deep learning (U‐Net)‐based workflow for classifying linear dune landforms based on the discrete Laplacian convolution of new global elevation dataset, AW3D30 digital surface model. Crest vectors were then derived landscape pattern analysis. The U‐Net crest classification model was trained and evaluated sample data from dunefields across Australian continent. resulting defect placement in typical semi‐arid arid landscapes eastern central Australia where...
Dust transported by Southern Hemisphere mid-latitude westerly winds from Australia and deposited in the Tasman Sea shows no evidence for stronger during last glacial maximum (LGM), compared to Holocene. Features of particle-size distributions dust do, however, indicate enhanced dry deposition LGM changing rainfall scavenging deglaciation early Holocene as climate ameliorated. From these results it appears that activation desert dunefields over 40% was result a reduction stabilizing...
In recent years, much research on modern and palaeotsunami deposits has been published. From these studies, a range of signature types identified. Identifying dating such is an important element in understanding late-Holocene tsunami hazard risk. However, questions as, ‘do leave similar or dissimilar traces?’ the same signatures all around world are there significant variations?’ ‘what actual record different parts world?’ still remain. Answering not easy task but examining megatsunami flood...
Abstract An Erratum has been published for this article in Earth Surfaces Processes and Landforms 25(13) 2005, 1683–1686. Recent determinations of soil production from situ cosmogenic nuclides indicate that decreases exponentially with depth. This contrasts a long‐held assumption maximum occurs under cover finite Sites the Blue Mountains, Australia, show sharp decrease depth where vegetation changes forested plateau surfaces to heath‐covered spurs, bands bare rock heath suggest depends on...
Abstract The degree to which Southern Hemisphere climatic changes during the end of last glacial period and early Holocene (30‐8 ka) were influenced or initiated by events occurring in high latitudes Northern is a complex issue. There conflicting evidence for hemispheric ‘teleconnection’ an unresolved debate as principle forcing mechanism(s). available hypotheses are difficult test robustly, however, because few detailed palaeoclimatic records widely dispersed lack duplication. Here we...
