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 [...]

Mesoscale Eddy-Induced Sharpening of Oceanic Tracer Fronts
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
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. [...]
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 [...]
