Interpretable Quality Control of Sparsely Distributed Environmental Sensor Networks Using Graph Neural Networks

Elżbieta Krystyna Lasota, Timo Houben, Julius Polz, et al.

Published: 2024-05-02
Subjects: Artificial Intelligence and Robotics, Earth Sciences

Environmental sensor networks play a crucial role in monitoring key parameters essential for understanding Earth’s systems. To ensure the reliability and accuracy of collected data, effective quality control (QC) measures are essential. Conventional QC methods struggle to handle the complexity of environmental data. Conversely, advanced techniques such as neural networks, are typically not [...]

Controls on mesophotic carbonate facies and sediment distribution across the Maltese shelf, central Mediterranean Sea

Or M. Bialik, Giovanni Coletti, Christian Berndt, et al.

Published: 2024-05-02
Subjects: Other Environmental Sciences, Sedimentology

Although ~20% of global carbonate occurs on extra-tropical shelves, our understanding of these depositional environments still lags far behind that of tropical carbonate platforms. The Maltese shelf in the central Mediterranean offers an opportunity to study in situ facies distribution in a light-dominated extra-tropical carbonate platform and the factors controlling them. The Maltese shelf [...]

A critical appraisal of water table depth estimation: Challenges and opportunities within machine learning

Joseph Janssen, Ardalan Tootchi, Ali A Ameli

Published: 2024-05-02
Subjects: Applied Statistics, Hydrology

Fine-resolution spatial patterns of water table depth (WTD) play a crucial role in shaping ecological resilience, hydrological connectivity, and anthropocentric objectives. Generally, a large-scale (e.g., continental or global) spatial map of static WTD can be simulated using either physically-based (PB) or machine learning-based (ML) models. We construct three fine-resolution (500 m) ML [...]

GeoAI and the Future of Spatial Analytics

Wenwen Li, Samantha T. Arundel

Published: 2024-05-01
Subjects: Computer Sciences, Earth Sciences, Environmental Sciences, Environmental Studies, Geography, Library and Information Science, Physical Sciences and Mathematics, Social and Behavioral Sciences

This chapter discusses the challenges of traditional spatial analytical methods in their limited capacity to handle big and messy data, as well as mining unknown or latent patterns. It then introduces a new form of spatial analytics – geospatial artificial intelligence (GeoAI) - and describes the advantages of this new strategy in big data analytics and data-driven discovery. Finally, a [...]

Integrating Vision-Based AI and Language Models for Real-Time Water Pollution Surveillance

Dinesh Jackson Samuel, Muhammed Yusuf Sermet, David Cwiertny, et al.

Published: 2024-05-01
Subjects: Electrical and Computer Engineering, Engineering

Water pollution has become a major concern in recent years, affecting over 2 billion people worldwide, according to UNESCO. This pollution can occur naturally, such as through algal blooms, or it can be man-made when toxic substances are released into water bodies like lakes, rivers, springs, and oceans. To address this issue and monitor surface-level water pollution in local water bodies, an [...]

Study on the Assessment of the Development Level of Digital Economy in the Yellow River Basin Economic Zone and the Evolution of Time and Space

Liang Wu, Zengzheng Li, Zhentao Gu, et al.

Published: 2024-05-01
Subjects: Statistics and Probability

Based on the Statistical Classification of the Digital Economy and Its Core Industries (2021) and considering the characteristics of the Yellow River Basin Economic Belt, this paper selects 25 secondary indicators from 5 dimensions (digital infrastructure, digital industrialization, industrial digitization, digital innovation and agricultural modernization). A scientific and practical evaluation [...]

SWOT Data Assimilation with Correlated Error Reduction: Fitting Model and Error Together

Yu Gao, Sarah T. Gille, Bruce D. Cornuelle, et al.

Published: 2024-05-01
Subjects: Oceanography, Oceanography and Atmospheric Sciences and Meteorology

The Surface Water Ocean Topography (SWOT) satellite mission provides high-resolution two-dimensional sea surface height (SSH) data with swath coverage. However, spatially correlated errors affect these SSH measurements, particularly in the cross-track direction. The scales of errors can be similar to the scales of ocean features. Conventionally, instrumental errors and ocean signals have been [...]

The rapid advancement of Large Language Models (LLMs), such as ChatGPT, has opened new horizons in the field of Artificial Intelligence (AI), revolutionizing the way we can engage with and disseminate complex information. This paper presents an innovative application of ChatGPT in the domain of Water Quality (WQ) management, through the development of an AI Hub. The Hub encompasses a suite of [...]

Is Net Zero Necessary? Meeting the Paris Agreement Temperature Target with 39% Global Emissions Reductions by the 2070s

Roy Warren Spencer

Published: 2024-04-30
Subjects: Physical Sciences and Mathematics

Global Carbon Project (GCP) data shows that natural processes have been sequestering atmospheric CO2 on a yearly basis in proportion to how much the atmospheric CO2 concentration has risen above pre-Industrial levels, the so-called CO2 “sink rate”. Here it is argued that the future trajectory of the sink rate has not been adequately addressed, which has led to overestimation of future atmospheric [...]

Nurturing a new industry rooted in geoscience: stakeholder insights on minewater thermal in Scotland.

Katherine Beth Deeming, Jen Dickie, Jen Roberts, et al.

Published: 2024-04-30
Subjects: Engineering, Social and Behavioral Sciences

Heat decarbonisation is crucial for climate action and to transition towards a sustainable society. Abandoned, flooded mines can be used to provide low-carbon heating and cooling for buildings or as thermal energy storage for district heating networks. Despite the plentiful potential resource that legacy mining infrastructure offers, the current utilisation of minewater thermal resources in the [...]

Carbonate clumped isotope values compromised by nitrate-derived NO2 interferent

Jens Fiebig, Miguel Bernecker, Niels Meijer, et al.

Published: 2024-04-30
Subjects: Earth Sciences, Geochemistry

∆47 based clumped isotope thermometry has enabled reconstruction of Earth’s surface temperatures independent of the source of oxygen within the carbonate. It has been postulated that carbonate samples can contain contaminants that cause isobaric interferences, compromising measured ∆47 values and reconstructed temperatures. The exact nature of contaminants and isobaric interferents, however, [...]

The linked complexity of coseismic and postseismic faulting revealed by seismo-geodetic dynamic inversion of the 2004 Parkfield earthquake

Nico Schliwa, Alice-Agnes Gabriel, Jan Premus, et al.

Published: 2024-04-26
Subjects: Physical Sciences and Mathematics

Several regularly recurring moderate-size earthquakes motivated dense instrumentation of the Parkfield section of the San Andreas fault, providing an invaluable near-fault observatory. We present a seismo-geodetic dynamic inversion of the 2004 Parkfield earthquake, which illuminates the interlinked complexity of faulting across time scales. Using fast-velocity-weakening rate-and-state friction, [...]

Owing to its deployment and sensing characteristics, Distributed Acoustic Sensing (DAS) has been touted as a promising technology for low-cost and low-latency Earthquake Early Warning (EEW). While preliminary experiments conducted by several research groups have yielded encouraging results, it must be acknowledged that these EEW feasibility studies were performed only on low-magnitude events.

Mapping microplastic movement: A phase diagram to predict microplastics modes of transport

Hadeel Al-Zawaidah, Merel Kooi, Ton Hoitink, et al.

Published: 2024-04-26
Subjects: Civil and Environmental Engineering

Microplastics pose numerous threats to aquatic environments, yet general understanding of the mechanisms governing their transport remains limited. Drawing upon research on natural sediment provides a valuable resource to address this knowledge gap. One key dimensionless number used to describe sediment transport is the transport stage, referring to the ratio between the fluids shear velocity and [...]
