Base metal mineralisation associated with Ordovician shales in south-west Scotland [PDF]

open access: yes, 1984
Several narrow, lenticular belts of black cherty mudstone and siltstone (the Moffat Shales), alternating with thick greywacke sequences, strike north-east to south-west across Galloway with uniformly steep dip.

Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

open access: yesNear Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

3-Space In-Flow Theory of Gravity: Boreholes, Blackholes and the Fine Structure Constant [PDF]

open access: yes, 2005
A theory of 3-space explains the phenomenon of gravity as arising from the time-dependence and inhomogeneity of the differential flow of this 3-space.

Wild meat consumption in changing rural landscapes of Indonesian Borneo

open access: yesPeople and Nature, EarlyView.
Abstract Wild meat can play a crucial role in the food system of rural communities residing near tropical forests. Yet, socio‐ecological changes across tropical landscapes are impacting the patterns and sustainability of meat consumption. To understand the prevalence, frequency and drivers of wild meat, domestic meat and fish consumption in this ...

Experiences with performing a thermal response test in boreholes for heat pumps [PDF]

open access: yesActa Montanistica Slovaca, 2006
This paper presents a Thermal Response Test (TRT) performed in two testing boreholes for heat pumps in the Czech Republic. The TRT is a special in-situ technique used abroad for the determination of key parameters needed for the proper borehole design ...

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

Effects of Surface Characteristics on the Existence of Isolated Permafrost in Northeastern Mongolia

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Isolated patches of permafrost, where ground thermal changes are affected by ecosystem factors such as vegetation cover rather than climate, may be vulnerable to environmental disturbances in semiarid regions. However, the impacts of ecosystem factors remain underevaluated in Mongolia.
