Download or read book Remote Field Methods to Measure Frost Depth written by CH. Benson and published by . This book was released on 1999 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews the three common methods used to remotely measure frost depth: (1) soil temperature measurements, (2) soil electrical resistivity measurements, and (3) soil dielectric constant measurements. Soil temperature measurements are often made using thermocouples or thermistors. Specially designed probes are used to measure frost depth based on electrical resistivity. Inferences based on dielectric constant are usually made using time domain reflectometry. Frost depths based on soil temperatures are made equally well using thermistors or thermocouples. However, frost depths inferred from soil temperature measurements can be erroneous if the freezing point is depressed (due to unsaturated conditions or the presence of salts) or if the temperature profile is essentially isothermal and near 0°C. More reliable measurements of frost depth are made using electrical resistivity or dielectric constant measurements because the electrical properties of soil are affected more by phase change of the pore water than temperature.

Book excerpt: The report describes a project designed to monitor subsurface road temperatures using electronic temperature probes. The function of the probes is to allow for real time access to accurate temperature readings at various levels of the subgrade. The frost probe system provides the following advantages: i) immediate feedback of information ii) the elimination of safety hazards (manual retrieval requires personnel on roadway) and iii) reduced cost (automated sensing system requires no manpower on roadway). The report concludes that the frost probe system proved successful in providing automated data collection capabilities for frost depth penetration measurement in roadway subgrades at remote sites. Expansion of the frost probe network to include additional sites is recommended.

Download or read book The North American Arctic written by Dwayne Ryan Menezes and published by UCL Press. This book was released on 2019-11-04 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Arctic addresses the emergence of a new security relationship within the North American North. It focuses on current and emerging security issues that confront the North American Arctic and that shape relationships between and with neighbouring states (Alaska in the US; Yukon, Northwest Territories and Nunavut in Canada; Greenland and Russia). Identifying the degree to which ‘domain awareness’ has redefined the traditional military focus, while a new human rights discourse undercuts traditional ways of managing sovereignty and territory, the volume’s contributors question normative security arrangements. Although security itself is not an obsolete concept, our understanding of what constitutes real human-centred security has become outdated. The contributors argue that there are new regionally specific threats originating from a wide range of events and possibilities, and very different subjectivities that can be brought to understand the shape of Arctic security and security relationships in the twenty-first century.
