Advancing Regional Flood Mapping in a Changing Climate: A HAND-Based Approach for New Jersey with Innovations in Catchment Analysis
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
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
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
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
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
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
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 [...]
Systematic losses in tree-canopy cover over three decades revealed by integrating complementary data sources
Published: 2023-11-02
Subjects: Environmental Monitoring, Sustainability
Losses and gains in canopy cover of the world’s tree canopies affect carbon stocks, species habitats, water cycles, and human livelihoods. Consistent and multi-decadal global data on tree-canopy cover dynamics are needed for modelling climate scenarios, tracking progress towards restoration targets, and diverse other research, management and policy applications. However, most data only map binary [...]
Sounding out the river: Seismic and hydroacoustic monitoring of bedload transport in an alluvial river
Published: 2023-11-02
Subjects: Earth Sciences, Environmental Sciences, Physical Sciences and Mathematics
Seismological observations provide a non-invasive and continuous means of indirect measurement of fluvial bedload transport (i.e. the transport of coarse granular material, as a function of water depth, in rivers). However, a significant challenge remains in independently characterising the seismic signature of bedload transport from other sources, such as turbulence. Previous research suggested [...]
PyIRoGlass: An Open-Source, Bayesian MCMC Algorithm for Fitting Baselines to FTIR Spectra of Basaltic-Andesitic Glasses
Published: 2023-11-02
Subjects: Earth Sciences, Geochemistry, Other Earth Sciences, Physical Sciences and Mathematics, Volcanology
Quantifying volatile concentrations in magmas is critical for understanding magma storage, phase equilibria, and eruption processes. We present PyIRoGlass, an open-source Python package for quantifying H2O and CO2 species concentrations in the transmission FTIR spectra of basaltic to andesitic glasses. We leverage a database of naturally degassed melt inclusions and back-arc basin basalts to [...]
