Modern-day data sets in geosciences may comprise hundreds or thousands of geolocated time series. Despite all the automated tools and new algorithms now available to process and prepare those data before using them in research projects, it can be useful or even necessary to visualise and investigate them manually. Whether it be for data quality assessment, for the preparation of a training data [...]

Dunes form where winds blow over a bed of mobile sediment grains – conditions that are common in our solar system. On Earth, dunes abound in arid continental interiors and along sandy coastlines. Dune fields have also been recognized on Venus, Mars, Saturn's moon Titan, and Pluto. In response to the different boundary conditions and other environmental forcings, dunes adopt a rich diversity [...]

Advances in space-based observation, using remotely sensed data, has proved to be an important tool to monitor the globe, including the areas inaccessible to humans. The Sundarban deltaic region, witnessing the confluence of vast expanses of tropical mangrove forests, tidal rivers, and estuaries, is one such area. Considered as one of the richest biodiversity hotspot zones on earth, home to a [...]

The Role of Continental Heterogeneity on the Evolution of Continental Margin Topography at Subduction Zones

Subjects: Earth Sciences, Geophysics and Seismology, Other Earth Sciences, Physical Sciences and Mathematics, Tectonics and Structure

The nature of the overriding plate plays a major role in shaping subduction zone processes. In particular, the highly heterogeneous continental lithosphere modulates intra-plate tectonics and the surface evolution of our planet. However, the role of continental heterogeneity is relatively under-explored for the dynamics of subduction models. We investigate the influence of rheological and density [...]

Garnet zoning patterns record multiple processes of chemical transfer during subduction

Freya Roxanne George, Daniel R Viete, Janaína N. Ávila, et al.

Subjects: Geology, Other Earth Sciences

Subduction facilitates the transfer of volatiles from the Earth’s surface to its interior. However, the rock-scale processes that govern the efficiency of deep volatile transfer are not fully understood. Garnets from subduction zone rocks commonly have fine-scale, oscillatory elemental zoning that is typically considered to record external fluid ingress/transfer. Elemental and oxygen-isotope [...]

Evaluating Climate Signals on Global Coastal Shoreline Positions A commentary on “Influence of El Niño on the variability of global shoreline position” by Almar and colleagues.

Subjects: Climate, Geomorphology, Oceanography, Other Earth Sciences, Other Environmental Sciences

Almar and colleagues (2023) are correct in stating that, “understanding and predicting shoreline evolution is of great importance for coastal management.” Amongst the different timescales of shoreline change, the interannual and decadal timescales are of particular interest to coastal scientists as they reflect the integrated system response to the Earth’s climate and its natural modes of [...]

Satellite-derived shorelines for monitoring of sandy beaches: a benchmark study

Satellite remote sensing is becoming a widely used monitoring technique in coastal sciences. Yet, no benchmarking studies exist that compare the performance of popular satellite-derived shoreline (SDS) mapping algorithms against standardized sets of inputs and validation data. Here we present a new benchmarking framework to evaluate the accuracy of shoreline change observations extracted from [...]

From space-time landslide susceptibility to landslide risk forecast

Tengfei Wang, Ashok Dahal, Zhice Fang, et al.

Published: 2023-06-10
Subjects: Earth Sciences, Other Earth Sciences, Physical Sciences and Mathematics

The literature on landslide susceptibility is rich with examples that span a large number of topics. However, the component that pertains to the extension of the susceptibility framework toward space-time modeling is largely unexplored. This statement is even more valid when looking at the landslide risk context, where hardly any scientific contribution investigates risk dynamics in space and [...]

Ten deep learning techniques to address small data problems with remote sensing

Anastasiia Safonova, Gohar Ghazaryan, Stefan Stiller, et al.

Subjects: Artificial Intelligence and Robotics, Other Earth Sciences

Researchers and engineers have increasingly used Deep Learning (DL) for a variety of Remote Sensing (RS) tasks. However, data from local observations or via ground truth is often quite limited for training DL models, especially when these models represent key socio-environmental problems, such as the monitoring of extreme, destructive climate events, biodiversity, and sudden changes in ecosystem [...]

Macroplastic fragmentation in rivers

The process of macroplastic (>0.5 cm) fragmentation results in the production of smaller plastic particles (micro- and nanoplastics), which threaten biota and human health and are difficult to remove from the environment. The global coverage and long retention times of macroplastic waste in fluvial systems (ranging from years to centuries) create long-lasting and widespread potential for its [...]

Salt‑rich versus salt‑poor structural scenarios in the central Northern Calcareous Alps: implications for the Hallstatt facies and early Alpine tectonic evolution (Eastern Alps, Austria)

Published: 2023-05-25
Subjects: Other Earth Sciences, Sedimentology, Tectonics and Structure

One of the most remarkable features of the central Northern Calcareous Alps (Eastern Alps, Austria) is the widespread presence of Upper Triassic deep-water carbonates (the Hallstatt facies) and Permo-Triassic evaporites resting on deep-water Middle Jurassic strata and their underlying Upper Triassic shallow-water carbonate platform successions. The Hallstatt facies and accompanying evaporites [...]

Global mean sea level higher than present during the Holocene

Global mean sea-level (GMSL) change can provide insight on how ice sheets, glaciers, and oceans respond to warming[1;2]. The Holocene (11.7 ka to present) marks a time when temperatures may have exceeded early industrial (1850 CE) values[3]. Evidence from Greenland[4] and Antarctica[5;6] indicates that both ice sheets retreated inland of their present-day extents during the Holocene, yet previous [...]

This paper presents the specific process we, as part of the Earth Science Information Partners (ESIP) Semantic Harmonization Cluster, used to harmonize terms from the Global Cryosphere Watch (GCW) compilation of cryospheric terms with the Semantic Web for Earth and Environmental Terminology (SWEET) and the Environment Ontology (ENVO). In addition, we summarize a number of leading practices which [...]

Subjects: Earth Sciences, Other Earth Sciences, Physical Sciences and Mathematics

Textural information, such as crystal size distributions (CSDs) or crystal aspect ratios are powerful tools in igneous petrography for interrogating the thermal history of rocks. They facilitate the investigation of crystal nucleation, growth and mixing as well as the cooling rate of the rock. However, they require large volumes of crystal segmentations and measurements that are often obtained [...]

Hydro-morphological processes (HMP, any natural phenomenon contained within the spectrum defined between debris flows and flash floods) are globally occurring natural hazards which pose great threats to our society, leading to fatalities and economical losses. For this reason, understanding the dynamics behind HMPs is needed to aid in hazard and risk assessment. In this work, we take [...]
