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 [...]

Fluvial reworking eliminates small craters, but does not meaningfully bias the Mars interbedded-crater record
Published: 2023-10-31
Subjects: Geomorphology, Planetary Geomorphology, Planetary Sedimentology, Sedimentology, Stratigraphy
Interpreting the structures, morphology, and chemistry of the exposed stratigraphic record on Mars is complicated by ancient surface processes that have variably removed parts of the record. Previous research has used the lack of smaller craters (<50 m diameter) interbedded with fluvial deposits to constrain atmospheric pressure when rivers were active on Mars; the notion being that higher [...]
Forest carbon market-based mechanisms in India: Learnings from global design principles and domestic barriers to implementation
Published: 2023-10-31
Subjects: Social and Behavioral Sciences
Forest carbon markets (FCMs) have emerged as a significant means to direct resources toward urgent climate action that can mobilize a large set of actors and catalyze funding toward reducing deforestation and promoting sustainable forest management. Here, we conduct a critical qualitative review of global academic and investigative literature to identify ten major sets of design principles that [...]
