Uncovering the Ground Thermal Regime of Coastal Labrador: The Influential Effects of Snow and Vegetation on Ground Temperatures
The ground thermal regime of Arctic and Subarctic regions is impacted by climate and local scale factors. Snow cover has been linked to differences in ground temperatures over short distances (< 5 m) because of its thermal buffering properties which slows energy exchanges between the ground and …

Air-ground temperature exchange
… the exchange of temperature between the air and ground surface remains constant. However, secular changes in boundary-layer factors can generate anomalous ground temperatures. This dissertation is an investigation of factors that cause separation of air and ground temperatures on a seasonal to …

Reduction of ground surface temperatures beside highway embankments by snow compaction, central Yukon, Canada.
… beside roads in permafrost regions, raise ground temperatures, may degrade permafrost locally and lead to deterioration of the embankment. Field experiments were conducted at tundra and taiga sites to determine whether compaction of snowbanks by snowmobiles would reduce ground temperatures, …

Examining the impact of heathland restoration via felling on carabid diversity in the Purbeck Heaths National Nature Reserve
… or >17 years (old). Environmental variables (ground temperature, soil moisture, and relative humidity) and vegetation characteristics were also recorded. Sampling was carried out monthly from May to August 2024, and data were analysed using generalised models (additive and linear) for species …

Vegetation Succession and Environmental Relations at the Illisarvik Drained Lake Experiment, Western Arctic Coast, Canada
… factors controlling active-layer thickness and ground temperatures at Illisarvik. The vegetation height likely acts as a proxy for the insulating influence of the snow.

Design Tool for a Ground-Coupled Ventilation System
Ground-coupled ventilation (GCV) is a system that exchanges heat with the soil. Because ground temperatures are relatively higher during the cold season and lower during the hot season, the system takes advantage of this natural phenomenon. This research focused on designing a ground-coupled …

Hydrogeomorphology of Lava Rise Pits in The Laki Lava Field, Southeast Iceland
… were primarily impacted by depth, pit openness, ground temperatures (GTs) and air temperature (AT). LRPs more open and exposed to the atmosphere, their near surface above-ground, and GTs mimicked ATs. Precipitation was the most important source of water, with overland flow, and groundwater …

The performance of an integral greenhouse solar air-heater
… low values of inlet-air temperature, different ground temperatures, different mass-flowrates and radiation intensities. Although subject to the input conditions, the results indicated an efficiency of solar energy collection of about 35 percent for the model greenhouse solar collector. The …

Where is the love? Experimental translocation of the threatened striped legless lizard (Delma impar) and an investigation of the habitat suitability of the invasive African lovegrass (Eragrostis curvula)
… structural complexity than kangaroo grass and ground temperatures rarely exceeded maximum lizard critical body temperature. D. impar selected complex grass structures in both grass species. As grass complexity increased, D. impar occupancy increased more rapidly in kangaroo grass than African …
