Landslides in the Thompson River Valley, British Columbia, Canada, threaten serviceability of two railway lines that connect Vancouver to rest Canada and US. To minimise impact slope instability on vital transport infrastructure, as well terrestrial aquatic ecosystems, public safety, communities, local heritage, economy, better inform decision making, there is a need for monitoring. Since 2013, Ripley Landslide – small, slow-moving, translational landslide has been focus monitoring efforts...
Abstract. Arctic regions are under immense pressure from a continuously warming climate. During the winter and shoulder seasons, recently deglaciated sediments particularly sensitive to human-induced warming. Understanding physical mechanisms processes that determine soil liquid moisture availability contributes way we conceptualize understand development functioning of terrestrial ecosystems. However, harsh weather logistical constraints limit opportunities directly observe subsurface...
Abstract. Arctic regions are under immense pressure from a continuously warming climate. Understanding the physical mechanisms and processes that determine soil liquid moisture availability contributes to way we conceptualize understand development functioning of terrestrial ecosystems. However, harsh weather logistical constraints limit opportunities directly observe subsurface year-round, hence automated uninterrupted strategies monitoring physicochemical properties essential....
ABSTRACT Accelerated climate warming is causing significant reductions in the volume of Arctic glaciers, such that previously ice‐capped bare ground uncovered, harboring soil development. Monitoring thermal and hydrologic characteristics soils, which strongly affect microbial activity, important to understand evolution emerging terrestrial landscapes. We instrumented two sites on forefield a retreating Svalbard glacier, representing sediment ages approximately 5 60 years since exposure. Our...
Abstract Soils are a fundamental natural resource but intensifying demands and increasing soil degradation necessitate focussed research into the sustainable use of soils. Since functioning is critical for operations performance multiple industries, businesses municipalities, scientists need to actively engage with these bodies orientate goals towards stakeholder needs. To achieve this, views about current potential contributions science different sectors be taken account when setting future...
Abstract Modern agricultural practices can cause significant stress on soil, which ultimately has degrading effects, such as compaction. There is an urgent need for fast, noninvasive methods to characterize and monitor compaction its impact hydraulic processes. Electrical resistivity tomography (ERT) a well‐established method used the assessment of soil properties due high temporal resolution sensitivity changes in moisture content salinity, whereas X‐ray computed (CT) be...
The Arctic is undergoing rapid changes in climate, altering the status and functioning of high-latitude soils permafrost. vast majority studies on permafrost are conducted during summer period due to ease accessibility, sampling, instrument operation, making measurements, comparison winter transition seasons. However, there increasing evidence that microbial activity continues outside period. Moreover, it becoming clear understanding seasonal dynamics critical importance, especially...
Quantitatively linking observations from independent non-invasive soil assessment methods enhances our ability to understand root zone processes. Electrical Resistivity Tomography (ERT) and X-ray Computed (CT) are two advanced technologies routinely employed in science. ERT allows 4D process monitoring ( e.g., solute transport) is sensitive changes moisture content (MC) texture. CT a higher resolution method used appraise structure. We measured the variation of electrical resistivity...
Summary Oil and gas exploration activities in the South Sumatra Basin area had been a mature phase were starting to be intense with deep drilling or targeting unconventional reservoirs. New discovery from Pertamina Hulu Rokan would breakthrough insight. A new play was found pyroclastic sandstone reservoir of Air Benakat Formation high gamma ray low resistivity characteristics relatively located shallow depths caused by last tectonic inversion. This kind which have natural gamma-rays easy...
Robust and timely assessment of the condition geotechnical infrastructure assets (e.g. cuttings, embankments, dams) is essential for cost effective maintenance engineering interventions to prevent failure events. Infrastructure slopes (in transportation, utilities water management) are experiencing increasingly high levels require considerable resources maintain; in order hundreds millions pounds per year UK alone. The issue accelerating asset deterioration being exacerbated by greater...
Summary Combining geophysical methods allows for the characterisation and monitoring of subsurface processes in landslide systems at unprecedented spatiotemporal resolutions. For high spatial resolution subsurface, that provide maps, cross-sections three-dimensional volumes data are preferred. An overview results various long-term campaigns using such Hollin Hill Landslide Observatory UK presented. These include electrical resistivity seismic tomography, self-potential mapping...
Summary Arctic regions are warming three to four times faster than the global average, with like Svalbard Archipelago experiencing significant reductions in ice-cover. This glacier retreat has exposed new terrestrial landscapes, which harbour emerging soils. In order help better understand how temperature and moisture dynamics vary depth over multiple time scales developing soil, we present results from two sensor installations located on forefield of Midtre Lovénbreen glacier, Svalbard....
Summary The UK Geoenergy Observatories (UKGEOS) project aims to advance our understanding of subsurface energy resources. A rapid grout level monitoring method using electrical contact resistance was developed and deployed in geothermal boreholes. This technique enables efficient assessment distribution during ground source heat (GSH) borehole installation, ensuring backfill integrity preventing blockage. study presents profiles for one GSH grouting stage, showing a clear interface between...
Summary Developing a better understanding of soil hydraulic properties is significant importance for such diverse fields as agriculture, and ecosystems management, civil engineering geotechnics. Electrical Resistivity Tomography (ERT) X-ray Computed (CT) are two state-of-the-art methodologies with great potential applications in science. ERT allows time-lapse monitoring solute transport.
