Fluvial reworking eliminates small craters, but does not meaningfully bias the Mars interbedded-crater record

Andrew Moodie, Timothy Goudge

Published: 2023-10-31
Subjects: Geomorphology, Planetary Geomorphology, Planetary Sedimentology, Sedimentology, Stratigraphy

Interpreting structures, morphology, and chemistry of the exposed stratigraphic record on Mars is complicated by ancient surface processes that 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 atmospheric [...]

Forest carbon market-based mechanisms in India: Learnings from global design principles and domestic barriers to implementation

Anirban Roy, Manan Bhan

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 [...]

Petrographic and geochemical evidence for a complex magmatic plumbing system beneath Bagana volcano, Papua New Guinea

Joshua Robert Brown, Iris Buisman, Maria Paula Castellanos Melendez, et al.

Published: 2023-10-31
Subjects: Earth Sciences, Geochemistry, Volcanology

Bagana is a persistently active stratovolcano located on Bougainville Island, Papua New Guinea. Characteristic activity consists of prolonged lava effusion over months to years, with occasional shifts to explosive vulcanian or subplinian eruptions which threaten surrounding communities. Satellite observations have shown that Bagana is a major SO2 emitter, particularly during eruptive intervals. [...]

Quantifying fault interpretation uncertainties and their impact on fault seal and seismic hazard analysis

Billy Andrews, Zoe K Mildon, Christopher Aiden-Lee Jackson, et al.

Published: 2023-10-31
Subjects: Geology, Tectonics and Structure

Fault-horizon cut-off data extracted from seismic reflection datasets are used to study the geometry, displacement distribution, and growth history of normal faults. Our study assesses the influence of three fault interpretation factors (repeatability, measurement obliquity, and cut-off type) on derived fault properties. We investigate uncertainties in throw, heave, displacement, and dip, [...]

Robustness of the evaluation of indirect costs of natural disasters: example of the ARIO model

Samuel Paul Juhel, Adrien Delahais, Vincent Viguié

Published: 2023-10-30
Subjects: Risk Analysis

Given the interconnectedness of economies and the prevalence of just-in-time production processes, even small interruptions to production caused by natural disasters can lead to great indirect economic impacts. A substantial body of literature on this subject exists, notably with the help of input-output analysis, CGE and agent-based models. However, such models rely on parameters and data which [...]

New insights into the Upper Pleistocene directed blast eruption, Popocatépetl volcano, México

R. Marcela Lira Beltrán, Lizeth Caballero, Delphine Sourisseau, et al.

Published: 2023-10-30
Subjects: Geology, Stratigraphy, Volcanology

Volcanic eruptions of the directed blast type can affect areas of hundreds of square kilometres and reach more than 25 km from the crater, as observed in the directed explosions of the Bezymianny (1956) and Mt. St. Helens (1980) volcanoes. These directed eruptions are characterized by powerful explosions with a significant lateral component that can travel at speeds above 100 m/s, which includes [...]

A Portable low-cost Device to Quantify Advective Gas Fluxes from Mofettes into the Lower Atmosphere: First Application to Starzach Mofettes (Germany)

Yann Georg Büchau, Carsten Leven, Jens Bange

Published: 2023-10-27
Subjects: Environmental Monitoring, Environmental Sciences, Physical Sciences and Mathematics

In this study, we introduce a portable low-cost device for in situ gas emission measurement from focused point sources of CO2, such as mofettes. We assess the individual sensors' precision with calibration experiments and perform an independent verification of the system's ability to measure gas flow rates in the range of liters per second. The results from one week of continuous CO2 flow [...]

Australia’s Tinderbox Drought: an extreme natural event likely worsened by human-caused climate change

Anjana Devanand, Georgina M. Falster, Zoe E. Gillett, et al.

Published: 2023-10-27
Subjects: Physical Sciences and Mathematics

We examine the characteristics and causes of southeast Australia’s Tinderbox Drought (2017–2019) that preceded the Black Summer fire disaster. The Tinderbox Drought was characterised by cool season rainfall deficits of around –50% in three consecutive years, which was exceptionally unlikely in the context of natural variability alone. The precipitation deficits were initiated and sustained by an [...]

Fantastic Wetlands and Why to Monitor Them: Demonstrating the Social and Financial Benefit Potential of Methane Abatement through Salt Marsh Restoration

Adam Reilly, Nathaniel Merrill, Kate Mulvaney, et al.

Published: 2023-10-27
Subjects: Environmental Studies

Salt marsh restoration has the potential to reduce greenhouse gas emissions thereby providing an opportunity for blue carbon crediting, but implementation has been limited to date because of insufficient data and validation. Freshening salt marshes are sources of methane emissions, which present an opportunity for states to address this source of potent greenhouse gas emissions if restored to [...]

Pacific shoreline erosion and accretion patterns controlled by El Niño/Southern Oscillation

Kilian Vos, Mitchell Dean Harley, Ian L Turner, et al.

Published: 2023-10-27
Subjects: Civil and Environmental Engineering, Climate, Earth Sciences, Engineering, Environmental Monitoring, Environmental Sciences, Geomorphology, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics

In the Pacific Basin, the El Niño/Southern Oscillation (ENSO) is the dominant mode of interannual climate variability, driving substantial changes in oceanographic forcing and impacting Pacific coastlines. Yet, how sandy coasts respond to these basin-scale changes has to date been limited to a few long-term beach monitoring sites, predominantly on developed coasts. Here we use 38 years of Landsat [...]

Testing the applicability of standardised growth curves (SGC) for chemically heterogeneous single-grain feldspars from the Atacama Desert, Chile

Linda Maßon, Svenja Riedesel, Anja Zander, et al.

Published: 2023-10-26
Subjects: Earth Sciences

The Atacama Desert is generally considered the driest non-polar desert on Earth and is therefore an ideal study area for exploring the water and biota free endmember of Earth’s Critical Zone (ECZ). Single grain (SG) luminescence dating has successfully identified processes in the ECZ. However, SG luminescence dating of Atacama Desert feldspars is challenging and time consuming since only a small [...]

High methane emissions from a eutrophic marine coastal basin driven by bubble release from the sediment

Olga Marzena Żygadłowska, Jessica Venetz, Wytze K. Lenstra, et al.

Published: 2023-10-25
Subjects: Biogeochemistry, Physical Sciences and Mathematics

The production of methane in coastal sediments and its release to the water column is intensified by anthropogenic eutrophication and bottom water hypoxia, and it is yet uncertain whether methane emissions to the atmosphere will be enhanced. Here, we assess seasonal variations in methane dynamics in a eutrophic, seasonally euxinic coastal marine basin (Scharendijke, Lake Grevelingen). In-situ [...]
