Intertwining volcanoes and society in Chile through arts and interdisciplinary connections
Published: 2023-11-08
Subjects: Geography, Social and Behavioral Sciences
The separation between nature and society, of concern within social science and interdisciplinary discussions, has generated a division that often characterizes the way communities perceive their environment. The arts have played an important role in demonstrating the entanglement of Earth and society through their ability to frame and shape the dynamics of the Earth across sensations. This has [...]
Impact of altimeter-buoy data pairing methods on the validation of Sentinel-3A coastal significant wave heights
Published: 2023-11-07
Subjects: Physical Sciences and Mathematics
Sea state information is critical for a broad range of human activities (e.g. shipping, marine energy, marine engineering) most of them being concentrated along the coastal zone. Satellite altimeter records of significant wave heights (SWH) represent the largest source of sea state observations available to date. However, the quality of altimeter observations is reduced in the coastal zone due to [...]
Changes in mesophotic carbonate-platform export across the end of the last glacial cycle (Saya de Malha Bank, western Indian Ocean)
Published: 2023-11-07
Subjects: Biogeochemistry, Geochemistry, Natural Resources and Conservation, Other Earth Sciences, Other Environmental Sciences, Paleobiology, Sedimentology, Stratigraphy
The export of neritic material from the top of carbonate platforms is a key process in the construction of their slopes. However, our knowledge of the supply pattern of materials from platforms is dominantly based on platforms lying in the euphotic zone during the present sea-level highstand. This is a somewhat biased perspective as through geological time not all platforms were euphotic. The [...]
Transgression–regression cycles drive correlations in Ediacaran–Cambrian rock and fossil records
Published: 2023-11-07
Subjects: Earth Sciences, Geology, Paleontology, Physical Sciences and Mathematics, Sedimentology, Statistical Methodology, Statistics and Probability, Stratigraphy
Strata of the Ediacaran Period (635–538.8 Ma) yield the oldest known fossils of complex, macroscopic organisms in the geologic record. These “Ediacaran-type” macrofossils (known as the Ediacaran biota) first appear in mid-Ediacaran strata, experience an apparent decline through the terminal Ediacaran, and directly precede the Cambrian (538.8–485.4 Ma) radiation of animals. Existing hypotheses for [...]
Wildfire smoke impacts lake ecosystems
Published: 2023-11-06
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Wildfire activity is increasing globally. The resulting smoke plumes can travel hundreds to thousands of kilometers, reflecting or scattering sunlight and depositing ash within ecosystems. Several key physical, chemical, and biological processes in lakes are controlled by factors affected by smoke. The spatial and temporal scales of lake exposure to smoke are extensive and underrecognized. We [...]
Petrological Evolution and Mass Redistribution in Basaltic Fault Zones: An Example from the Faroe Islands, North Atlantic Igneous Province
Published: 2023-11-06
Subjects: Earth Sciences, Geochemistry, Geology, Tectonics and Structure
Fault rock petrology exerts an important control on the permeability structure and mechanical properties of fault zones. Slip-related deformation on upper-crustal faults in basaltic rocks is closely associated with fluid-rock interaction, altering the distribution of physical properties within the fault. Here we present quantitative descriptions of the geochemical and petrological evolution of [...]
Deep Learning for Deep Earthquakes: Insights from OBS Observations of the Tonga Subduction Zone
Published: 2023-11-06
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics
Applications of machine learning in seismology have greatly improved our capability of detecting earthquakes in large seismic data archives. Most of these efforts have been focused on continental shallow earthquakes, but here we introduce an integrated deep-learning-based workflow to detect deep earthquakes recorded by a temporary array of ocean-bottom seismographs (OBSs) and land-based stations [...]
A framework for integrated monitoring of status and trends in water balance, water chemistry and contamination of shallow lakes across a remote dynamic freshwater delta
Published: 2023-11-05
Subjects: Environmental Sciences
Systematic and sustainable monitoring approaches capable of tracking the status and trends of keystone characteristics are critical for detecting aquatic ecosystem degradation, identifying the influence of multiple potential stressors, informing environmental protection policy and anticipating future change. At remote lake-rich landscapes, ability to implement and maintain long-term monitoring is [...]
Warm Arctic-Cold Eurasia Pattern Driven by Atmospheric Blocking in Models and Observations

Mesoscale Eddy-Induced Sharpening of Oceanic Tracer Fronts and its Parameterization
Published: 2023-11-04
Subjects: Oceanography
Oceanic fronts are ubiquitous and important features that form and evolve due to multiscale oceanic and atmospheric processes. For example, large-scale temperature and tracer fronts along the eastward extensions of the Gulf Stream and Kuroshio currents play key roles in the regional ocean environment and climate. The fronts cannot be realistically simulated by numerical models at spatial [...]
Understanding the role of biodiversity in the climate, food, water, energy, transport and health nexus in Europe
Published: 2023-11-04
Subjects: Life Sciences, Social and Behavioral Sciences
Biodiversity underpins the functioning of ecosystems and the diverse benefits that nature provides to people, yet is being lost at an unprecedented rate. To halt or reverse biodiversity loss, it is critical to understand the complex interdependencies between biodiversity and key drivers and sectors to inform the development of holistic policies and action. We conducted a literature review on the [...]
Microphysical evolution in mixed-phase mid-latitude marine cold-air outbreaks
Published: 2023-11-03
Subjects: Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Five cold-air outbreaks are investigated with aircraft offshore of continental northeast American. Flight paths aligned with the cloud-layer flow span cloud-top temperatures of -5 to -12 0C, in situ liquid water paths of up to 600 g m-2, while in situ cloud droplet number concentrations exceeding 500 cm-3 maintain effective radii below 10 micron. Ice is usually present at cloud initiation. [...]

Paleogeography and 3D variability of a dynamically uplifted shelf: observations from seismic stratigraphy of the Paleocene East Shetland Platform
Published: 2023-11-03
Subjects: Physical Sciences and Mathematics
In the Paleocene North Sea, pulses in turbidite fan deposition and shelfal progradation have been correlated to episodes of regional uplift caused by a precursor of the Icelandic Plume. However, in the East Shetland Platform, the specific impacts of dynamic uplift on the regional paleogeographic evolution are less understood. Using new, high resolution 3D seismic data from an underexplored [...]

Published: 2023-11-03
Subjects: Civil Engineering, Environmental Engineering, Environmental Sciences, Risk Analysis
Natural hazards impact the interdependent infrastructure networks that keep modern society functional. While a variety of critical infrastructure network (CIN) modelling approaches are available to represent CI networks on different scales and analyse the impacts of natural hazards, a recurring challenge for all modelling approaches is the availability and accessibility of sufficiently [...]
