Geochemical mapping by unmixing alluvial sediments: An example from northern Australia

Alex George Lipp, Patrice de Caritat, Gareth G Roberts

Published: 2022-10-01
Subjects: Earth Sciences, Environmental Monitoring, Environmental Sciences, Geochemistry, Geomorphology, Natural Resource Economics, Sedimentology, Soil Science, Water Resource Management

Alluvial sediments have long been used in geochemical surveys as their compositions are assumed to be representative of areas upstream. Overbank and floodplain sediments, in particular, are increasingly used for regional to continental-scale geochemical mapping. However, during downstream transport, sediments from heterogeneous source regions are carried away from their source regions and mixed. [...]

Global dynamics of the offshore wind energy sector monitored with Sentinel-1: Turbine count, installed capacity and site specifications

Thorsten Hoeser, Claudia Kuenzer

Published: 2022-04-26
Subjects: Applied Statistics, Earth Sciences, Environmental Sciences, Natural Resource Economics, Natural Resources Management and Policy, Oil, Gas, and Energy, Other Earth Sciences, Statistics and Probability

With the promotion of renewable energy production and a planned phaseout of fossil fuels until 2040, the offshore wind energy sector has started to expand and will continue to increase its capacity in the upcoming decades. This study presents how the installed capacity can be derived from radar imagery provided by the Sentinel-1 mission for all offshore wind turbines on the entire Earth. By [...]

Economic and biophysical limits to seaweed-based climate solutions

Julianne DeAngelo, Benjamin Saenz, Isabella Arzeno-Soltero, et al.

Published: 2022-02-12
Subjects: Earth Sciences, Environmental Sciences, Natural Resource Economics, Other Earth Sciences, Other Environmental Sciences, Sustainability

Net-zero greenhouse gas emissions targets are driving interest in opportunities for biomass-based negative emissions and bioenergy, including from marine sources such as seaweed. Yet the biophysical and economic limits to farming seaweed at scales relevant to the global carbon budget have not been assessed in detail. We use coupled seaweed growth and technoeconomic models to estimate the costs of [...]

Reproducibility in subsurface geoscience

Published: 2021-10-26
Subjects: Biogeochemistry, Cosmochemistry, Earth Sciences, Environmental Education, Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Geochemistry, Geology, Geomorphology, Geophysics and Seismology, Glaciology, Hydrology, Mineral Physics, Natural Resource Economics, Natural Resources and Conservation, Natural Resources Management and Policy, Oil, Gas, and Energy, Other Earth Sciences, Other Environmental Sciences, Paleobiology, Paleontology, Sedimentology, Soil Science, Speleology, Stratigraphy, Sustainability, Tectonics and Structure, Volcanology, Water Resource Management

Reproducibility, the extent to which consistent results are obtained when an experiment or study is repeated, sits at the foundation of science. The aim of this process is to produce robust findings and knowledge, with reproducibility being the screening tool to benchmark how well we are implementing the scientific method. However, the re-examination of results from many disciplines has caused [...]

Safety and Belonging in the Field: A Checklist for Educators

Ensuring taught fieldwork is a positive, generative, collective, and valuable experience for all participants requires considerations beyond course content. To guarantee safety and belonging, participants’ identities (backgrounds and protected characteristics) must be considered as a part of fieldwork planning and implementation. Furthermore, getting fieldwork right is an important step in [...]

Airborne methane surveys pay for themselves: An economic case study of increased revenue from emissions control

Forrest Johnson, Andrew Wlazlo, Ryan Keys, et al.

Published: 2021-07-15
Subjects: Environmental Monitoring, Natural Resource Economics, Oil, Gas, and Energy, Remote Sensing

We present an economic analysis of an emissions monitoring and capture program for a mid-sized Permian Basin operator, Triple Crown Resources (“Triple Crown”). Data from this campaign was gathered using repeat airborne surveys provided by Kairos Aerospace (“Kairos”). Key findings include: - The total volume of detected emissions from Triple Crown operations decreased by 70% from the first to the [...]

Defining a Sustainable Development Target Space for 2030 and 2050

Detlef van Vuuren, Caroline Zimm, Sebastian Busch, et al.

Published: 2021-05-24
Subjects: Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Environmental Studies, Natural Resource Economics, Other Environmental Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences, Sustainability

By adopting the Sustainable Development Goals (SDGs), countries worldwide agreed to an agenda for achieving a prosperous, socially inclusive and environmentally sustainable future for all1. This ambition, however, also exposes a critical knowledge gap since science-based insights on how to achieve the 17 SDGs simultaneously are lacking. Quantitative goal-seeking scenario studies could enable [...]

Evaluating the Economic Fairways for Hydrogen Production in Australia

Stuart Duncan Christopher Walsh, Laura Easton, Zhehan Weng, et al.

Published: 2021-05-20
Subjects: Chemical Engineering, Natural Resource Economics, Natural Resources Management and Policy, Physical and Environmental Geography, Power and Energy, Water Resource Management

Assessments of hydrogen project viability typically focus on evaluating specific sites for development, or providing generic cost-estimates that are independent of location. In reality, the success of hydrogen projects will be intimately linked to the availability of local energy resources, access to key infrastructure and water supplies, and the distance to export ports and energy markets. In [...]

Bridging the gap between geophysics and geology with Generative Adversarial Networks (GANs)

Suihong Song, Tapan Mukerji, Jiagen Hou

Inverse mapping from geophysics to geology is a difficult problem due to the inherent uncertainty of geophysical data and the spatially heterogeneous patterns (structure) in geology. We describe GANSim, a type of generative adversarial networks (GANs) that discovers the mapping between remotely-sensed geophysical information and geology with realistic patterns, with a specially designed loss [...]

Crop residues are a key feedstock to bioeconomy but available methods for their estimation are highly uncertain

Crop residues are acknowledged as a key biomass resource to feed tomorrow’s sustainable bioeconomy. Yet, the quantification of these residues at large geographical scales is primarily reliant upon generic statistical estimations based on empirical functions linking the residues production to the primary crop yield. These useful yet unquestioned functions are developed either using direct evidence [...]

The role of glacier retreat for Swiss hydropower production

Published: 2017-12-22
Subjects: Earth Sciences, Engineering, Environmental Sciences, Glaciology, Hydrology, Natural Resource Economics, Natural Resources Management and Policy, Physical Sciences and Mathematics, Sustainability, Water Resource Management

High elevation or high latitude hydropower production (HP) strongly relies on water resources that are influenced by glacier melt and are thus highly sensitive to climate warming. Despite of the wide-spread glacier retreat since the development of HP infrastructure in the 20th century, little quantitative information is available about the role of glacier mass loss for HP. We provide the first [...]
