MinPlotX: A powerful tool for formula recalculation, visualization, and comparison of large mineral compositional datasets
Published: 2024-12-19
Subjects: Earth Sciences, Physical Sciences and Mathematics
MinPlotX is an open-source software for mineral formula recalculation and compositional plotting providing an easy-to-use stand-alone graphical user interface (GUI) as well as an advanced programming interface (API). The aim of MinPlotX is to provide publication-ready tables of mineral formulae and plots of mineral composition. The new GUI-based approach allows for a wider variety of calculation [...]
A simplified physics model for estimating subsurface CO2 storage resources constrained by fault slip potential
Published: 2024-12-19
Subjects: Earth Sciences
Carbon Capture and Storage (CCS) at rates of several gigatonnes (Gt) per year may be needed to mitigate climate change. However, one major uncertainty is that the risk of injection-induced earthquakes may grow with this scale of deployment. In this work, we develop a tool, named CO2BLOCKSEISM, which uses simplified physics models to screen subsurface storage resources constrained by fault [...]
ESG mapping of the Australian mining sector – The state of play on mobilising spatial datasets for decision making
Published: 2024-12-19
Subjects: Life Sciences
The global energy transition will drive increased demand for a broad range of mined minerals.40 Australia is well positioned to support the global energy transition, given its mature mining sector41 and rich and diverse mineral resources. The potential growth in the mining sector represents an42 economic opportunity, however, navigating the associated environmental, social, and governance43 (ESG) [...]
Stories, Storytelling and Storylines for Geoscience Communication
Published: 2024-12-19
Subjects: Physical Sciences and Mathematics
Geoscientists need to recognize and embrace our role as storytellers, so that we can more effectively use storytelling to advance our science. As narrative-driven storylines become an increasing tool in disaster and climate risk communications, understanding the ‘science’ of stories and storytelling becomes an ever more critical geoscientific skillset.
Temporal variation in counterclockwise vertical-axis block rotations across a rift overlap zone, southwestern Ethiopia, East Africa
Published: 2024-12-18
Subjects: Tectonics and Structure
The southward propagation of the southern Main Ethiopian Rift (sMER) and the northward propagation of the Kenya Rift have generated the Broadly Rifted Zone (BRZ), a ~40-km-wide region of extensional overlap between the Chew Bahir Basin-Gofa Province and the sMER. However, the tectonic interaction between these propagating rifts is not well-understood. We present new paleomagnetic and [...]
Impact of farm size on the function of landscape-level payments for ecosystem services: An agent-based model study
Published: 2024-12-18
Subjects: Environmental Health and Protection, Environmental Sciences, Sustainability
Reducing pesticide use and restoring biodiversity are among the most pressing environmental challenges. Enhancing natural pest control ecosystem services through the integration of non-crop habitats (NCH) offers promising potential, creating a positive feedback loop by harnessing insect biodiversity to reduce pesticide reliance. Policy support is needed at the landscape level to encourage [...]
SC-PREC4SA: A serially complete daily precipitation dataset for South America
Published: 2024-12-18
Subjects: Engineering, Physical Sciences and Mathematics
This study introduces the serially complete precipitation dataset for South America (SC-PREC4SA), a daily precipitation dataset (1960-2015) designed to address observational gaps and ensure temporal consistency across diverse climates. The raw dataset underwent quality control, gap-filling, and homogenization procedures. Applied robust quality control highlighted common but also overlooked [...]
Catastrophe risk models as quantitative tools for climate change loss and damage: A demonstration for flood in Malawi, Vietnam, and the Philippines
Published: 2024-12-18
Subjects: Environmental Sciences
We show how catastrophe models, as commonly used in the insurance and reinsurance industries, can be used to quantify climate change loss(es) and damage(s), fulfilling a key need to make urgent progress in this arena of international climate policy. We explore the impact of climate change on inland flood risk in three Global South regions (Chikwawa in Malawi, Hanoi in Vietnam, and Cagayan in the [...]
Projecting Global Changes in Land Use and Ecosystem Services Using SEALS (Spatial Economic Allocation Landscape Simulator)
Published: 2024-12-18
Subjects: Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Spatial Science, Statistical Models
Understanding how economic systems and ecosystems interact across space is crucial to ensure societal needs are met without compromising environmental quality. Spatially explicit economic models usually describe human activities and ensuing land-use dynamics at a resolution that this is too coarse (typically 10-1000 regions) to understand how these affect many biophysical processes, including [...]
Delineating HCV forest areas using density analysis: it's not clear-cut
Published: 2024-12-18
Subjects: Natural Resources and Conservation
High conservation value (HCV) areas include natural habitats with high ecological, biological, social or cultural values. The use of spatial analysis using Geographic Information Systems (GIS) to identify HCV areas is more cost-efficient and less time consuming that field surveys. GIS-based approaches can also be necessary for identifying HCV areas in heterogeneous landscapes where, e.g., HCV [...]
Evaluating Temporal and Spatial Variations in Vegetation Coverage in the Inner Mongolia Autonomous Region (2004-2023) Using kNDVI
Published: 2024-12-18
Subjects: Higher Education
The Inner Mongolia Autonomous Region (IMAR) is a crucial ecological zone in China, facing significant environmental challenges, particularly climate change. To better understand vegetation dynamics in this region, this study examines vegetation cover trends from 2004 to 2023 and identifies their driving factors using an innovative kernel-based Normalized Difference Vegetation Index (kNDVI) [...]
Internal Oscillations of Tropical Mesoscale Convective Disturbances
Published: 2024-12-18
Subjects: Physical Sciences and Mathematics
In real-world observations, long-lived tropical mesoscale convective disturbances (MCDs) often exhibit quasi-periodic variations. Previous studies suggested that these variations are mainly induced by external forcings. However, some studies showed evidence that tropical MCDs can display quasi-periodic behavior even without external forcings. In this study, a suite of idealized [...]
Evaluation of Vegetation Bias in InSAR Time Series for Agricultural Areas within the San Joaquin Valley, CA
Published: 2024-12-18
Subjects: Physical Sciences and Mathematics
Agricultural regions present a particularly difficult set of challenges during interferometric synthetic aperture radar (InSAR) displacement time series analyses due to the existence of abrupt transitions in land use over short spatial scales and rapid temporal changes associated with different stages of the agricultural cycle. Plant growth and soil moisture changes can introduce phase biases [...]
An Irish female pioneer in geology: Mary Katherine Andrews (1852 - 1914)
Published: 2024-12-18
Subjects: Physical Sciences and Mathematics
Mary Katherine Andrews (1852–1914) was a woman of her time, a Victorian then Edwardian lady interested in science. Raised in an academic household in Belfast, she did not have the opportunity to attend university, because women were not accepted when she was young. This did not discourage her in developing her scientific interests, and she became an accomplished amateur geologist. The quality of [...]
On the assessment of sinking particle fluxes from in situ particle size distributions
Published: 2024-12-16
Subjects: Biogeochemistry, Earth Sciences, Other Earth Sciences
The biological carbon pump plays a crucial role in the global carbon cycle, particularly through sinking particles carrying carbon to deep waters. The Underwater Vision Profilers (UVP) is widely used for studying particle properties. UVP-based particulate organic carbon (POC) flux is typically derived from particle size distributions (PSDs) assuming size dependent sinking rates and carbon [...]
