Subjects: Artificial Intelligence and Robotics, Dynamic Systems, Hydrology, Natural Resources and Conservation

Machine learning (ML) is becoming an ever more important tool in hydrologic modeling. Many studies have shown the higher prediction accuracy of the ML models over traditional process-based ones. However, there is another advantage of ML which is its lower computer time of execution. This is important for the applications such as hydraulic soil erosion estimation over a large area and at a finer [...]

Contemporary Remote Sensing Tools for Integrated Assessment and Conservation Planning of Ice-free Antarctica

Larissa Patricio Valerio, Justine Shaw, Felipe Gonzalez, et al.

Published: 2022-06-17
Subjects: Environmental Monitoring, Natural Resources and Conservation, Remote Sensing

Monitoring and understanding Antarctica is critical for conservation of its values. Remote sensing has been increasingly employed to observe large areas at higher frequency than traditional monitoring methods, enabling systematic assessments at low cost. However, currently there are limitations in the ability of the available remote sensing tools to answer the most pressing scientific, [...]

PING-Mapper: open-source software for automated benthic imaging and mapping using recreation-grade sonar

Cameron Bodine, Daniel David Buscombe, Rebecca J Best, et al.

Published: 2022-06-14
Subjects: Environmental Monitoring, Hydrology, Natural Resources and Conservation

The characterization of benthic habitats is essential for aquatic ecosystem science and management, but is frequently limited by waterbody visibility and depth. Recreation-grade side scan sonar systems are increasingly used to aid scientific inquiries in shallow water due to their relative low-cost, ease of operation, low-weight, and ease of mounting on a variety of vessels. However, existing [...]

The historical impact of anthropogenic air-borne sulphur on the Pleistocene rock art of Sulawesi

Michael Gagan, Halmar Halide, Raden Permana, et al.

Published: 2022-05-31
Subjects: Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Sciences, Geochemistry, Natural Resources and Conservation

The Maros-Pangkep karst in southwest Sulawesi, Indonesia, contains some of the world’s oldest rock art. However, the Pleistocene images survive only as weathered patches of pigment on exfoliated limestone surfaces. Salt efflorescence underneath the case-hardened limestone substrate causes spall-flaking, and it has been proposed that the loss of artwork has accelerated over recent decades. Here, [...]

Paleoclimate controls on lithium enrichment in Great Basin Pliocene-Pleistocene lacustrine clays

Catherine A Gagnon, Kristina Butler, Elizabeth Gaviria, et al.

Published: 2022-05-29
Subjects: Climate, Earth Sciences, Environmental Sciences, Geochemistry, Geology, Natural Resources and Conservation, Other Environmental Sciences, Sedimentology

Terminal lakes are important archives of continental hydroclimate and in some cases contain important economic resources. Here we present an ~3.6 Myr lacustrine carbonate carbon and oxygen stable isotope record from a Great Basin continental drill core. We pair these measurements with bulk lithium concentrations to reveal a relationship between past climate and lithium enrichment in authigenic [...]

Groundwater in complex adaptive social-ecological systems

Xander Huggins, Tom Gleeson, Juan Castilla-Rho, et al.

Published: 2022-04-08
Subjects: Dynamical Systems, Hydrology, Natural Resources and Conservation, Natural Resources Management and Policy, Nature and Society Relations, Sustainability, Water Resource Management

Groundwater is embedded in social and ecological systems but the complexity of these interactions is not well represented in conventional approaches to study and promote groundwater sustainability. We argue an important shift is necessary in groundwater sustainability thinking: towards prioritizing the functions of groundwater, and the services that make it a critical resource, and away from [...]

Reproducibility in subsurface geoscience

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 [...]

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 [...]

As part of the UN Sustainable Development Goal 15 (Life on Land), the indicator 15.3.1 is adopted to measure the Land Degradation Neutrality. Land Degradation Neutrality is addressed as stable —or increasing— state in the amount and quality of land resources required to support ecosystem functions and services and enhance food security during a certain period of time. It is a binary indicator [...]

High resolution, annual maps of field boundaries for smallholder-dominated croplands at national scales

Mapping the characteristics of Africa's smallholder-dominated croplands, including the sizes and numbers of fields, can provide critical insights into food security and a range of other socioeconomic and environmental concerns. However, accurately mapping these systems is difficult because there is 1) a spatial and temporal mismatch between satellite sensors and smallholder fields, and 2) a lack [...]

Subjects: Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Geomorphology, Natural Resources and Conservation, Sedimentology

Loose sand has a wide variety (over 200) of industrial usage where most of the sand is used in infrastructure. Due to its low cost / high benefit nature and international high demand, worldwide examples of excessive sand mining caused complete destruction of habitats and forcing natives change living practices or even to migrate. Sand mining is one of the most controversial and rapidly growing [...]

Australia is the second driest continent on Earth and freshwater is, therefore, a critical policy concern. Farm dams are ubiquitous and drive AU$17.7 billion of agricultural value, yet there has never been a formal census of Australian dams. In this study, we present a continental-scale assessment on density, distribution, and historical trends of farm dams in each State and Territory of [...]
