Deep Learning for Deep Earthquakes: Insights from OBS Observations of the Tonga Subduction Zone

Ziyi Xi, Songqiao Shawn Wei, Weiqiang Zhu, et al.

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

Laura Neary, Casey R Remmer, Tanner J Owca, et al.

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 [...]

Mesoscale Eddy-Induced Sharpening of Oceanic Tracer Fronts

Yueyang Lu, Igor Kamenkovich

Published: 2023-11-04
Subjects: Oceanography

Oceanic fronts are ubiquitous and important features that form and evolve due to multiscale oceanic and atmospheric processes. Large-scale temperature and tracer fronts, such as those found along the eastward extensions of the Gulf Stream and Kuroshio currents, are crucial components of the regional ocean environment and climate. This numerical study examines the relative importance of [...]

Understanding the role of biodiversity in the climate, food, water, energy, transport and health nexus in Europe

HyeJin Kim, Anita Lazurko, George Linney, et al.

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

Paquita Zuidema, Seethala Chellappan, Simon Kirschler, et al.

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. [...]

Advancing Regional Flood Mapping in a Changing Climate: A HAND-Based Approach for New Jersey with Innovations in Catchment Analysis

David Bazzett, Ruo-Qian Wang, Lucas Marxen

Published: 2023-11-03
Subjects: Civil Engineering, Environmental Engineering, Hydraulic Engineering, Hydrology

Regional flood mapping poses computational and spatial heterogeneity challenges, exacerbated by climate change-induced uncertainties. This study focuses on creating a state-wide flood mapping solution with enhanced accuracy and computational speed to support regional flooding hazard analysis and the assessment of climate change, using New Jersey as a case study. The Height Above Nearest Drainage [...]

Paleogeography and 3D variability of a dynamically uplifted shelf: observations from seismic stratigraphy of the Paleocene East Shetland Platform

Lucas Valore, Tor Sømme, Stefano Patruno, et al.

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 [...]

Data for Critical Infrastructure Network Modelling of Natural Hazard Impacts: Needs and Influence on Model Characteristics

Roman Schotten, Evelyn Mühlhofer, Georgios Alexandros Chatzistefanou, et al.

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 [...]

Excited state lifetime of electron trapping centres in alkali feldspars

Svenja Riedesel, Mayank Jain

Published: 2023-11-02
Subjects: Earth Sciences, Mineral Physics, Other Earth Sciences, Physical Sciences and Mathematics, Physics

The development of the infrared photoluminescence (IRPL) signal enables the direct non-destructive probing of the trapped electron population in feldspars. Whilst IRPL offers new perspectives for luminescence dating, it also enables detailed, site-selective measurements of the dosimetric defects emitting IRPL at 880 nm (IRPL880) and 955 nm (IRPL955), allowing improved understanding of [...]

Middle Miocene vegetation of the Vallès-Penedès Basin (NE Iberian Peninsula), as inferred from fossil pollen records: state of the art and future prospects

Valentí Rull, David Alba, Isaac Casanovas

Published: 2023-11-02
Subjects: Other Plant Sciences, Paleontology

In the Mediterranean region, the study of fossil pollen has provided a comprehensive spatiotemporal paleoclimatic and paleovegetational picture of the Neogene flora and vegetation. The NW Mediterranean sector is a reference area for the study of vertebrate evolution, especially during the Middle Miocene, but paleofloristic and paleovegetational patterns are much less known, which hinders placing [...]

Observations of beach cusp morphodynamics on a composite beach

Sebastian Pitman, Giovanni Coco, Deirdre Hart, et al.

Published: 2023-11-02
Subjects: Geology, Geomorphology

Substantial volumes of sediment are moved on coarse grained beaches through the formation and destruction of beach cusps, yet the processes governing cusp behaviour remain poorly understood. Here, we combine continuous 2D LiDAR scan data with daily UAV topographic surveys and RGB imagery to provide detailed morphological measurements of beach cusps on a composite beach with the aim to investigate [...]

Factors influencing access to safely managed sanitation in sub-Saharan Africa: a systematic review protocol

Beatrice Chiwala, Choolwe Jacobs, Mpundu Makasa, et al.

Published: 2023-11-02
Subjects: Public Health

Introduction   Several interventions have been implemented to improve access for all to safely managed sanitation in sub-Saharan Africa (SSA) since the beginning of the Sustainable Development Goals in September 2015. However, consolidated evidence on how such interventions worked or not worked remains limited. The proposed systematic review aims to synthesis evidence on how, why and under which [...]
