Book excerpt: In June and July of 1964, extensive field trials of radar ice sounding equipment were held on the ice sheet in northwest Greenland. The results, in the form of profiles over 350 km of trail, made from seismic depth measurements along the Tuto-Century trail and Project 42 trails provide a good representation of surface and subsurface topography. A continuous trace of the ice/bedrock interface was obtained for over 97% of the route traveled, through ice up to 1400 meters thick. The film record obtained by the Scott Polar Research Institute, as a result of providing the Scott Polar Research radar set with continuously moving photographic film to record echo traces, shows a richness of detail (internal structure of the ice sheet) not portrayed by the manual plot. A sample of this film is given. References are made to project work of previous seasons. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The remote measurement of sea ice thickness from a mobile platform has been a goal of researchers and organizations, such as the U.S. Coast Guard, for many years. Ice thickness data is needed over large areas for icebreakers operation and navigation. The objective of this contract is to evaluate a successful ground-based sea ice profiling radar when adapted to a helicopter platform. The electronic and recording equipment were mounted in a small helicopter and the radar antenna was slung on a rope 14 m. below the helicopter. The thickness of fresh water ice and sea ice was successfully measured in the Canadian Arctic near Inuvik, N.W.T. Over 50 km. of first-year sea ice were continuously profiled. The ice thickness varied from 0.5 m. to 2 m. and the wind-swept snow cover varied from zero to 0.3 m. In the traverse mode, sea ice thickness was continuously measured at an altitude of 40 m. and a speed of 65 km/hr. Theoretical considerations and experimental results are given. (Author).
Book Synopsis Underway Ice Thickness Profiling Using Impulse Radar - CGC POLAR SEA Experiment, February 1981 by : P. A. Tebeau
Download or read book Underway Ice Thickness Profiling Using Impulse Radar - CGC POLAR SEA Experiment, February 1981 written by P. A. Tebeau and published by . This book was released on 1982 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field experiment was conducted in February 1981 to determine the feasibility of impulse radar sea ice profiling from the bow of the icebreaker CGC POLAR SEA. This experiment was conducted in offshore areas to the north and west of Point Barrow Alaska. The objectives of the experiment were to determine the feasibility of taking underway impulse radar profiles from an icebreaker for use in ice surveys and icebreaker performance tests, and to investigate the utility of the impulse radar system as an operational ice reconnaissance tool. The experiment was unsuccessful in that the system was unable to produce a recognizable profile of the ice/water interface over an extended portion of the ship's track. Intermittent subsurface reflections in the profiles could not be identified due to lack of ground truth data. The lack of success was attributed primarily to interference from the ship's hull and limited penetrating power of the radar system used in the tests. (Author).

Download or read book Cold Regions Technical Digest. Radar Profiling of Ice Thickness written by and published by . This book was released on 1985 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large-scale profiling of the thickness of freshwater and sea ice is important for understanding the dynamics of a sea ice covers, interpreting satellite microwave imagery, and predicting air-sea heat exchange or the bearing capacity of an ice cover. A practical approach to thickness sensing would be to use a remote ranging system that sends and receives a pulse of energy that reflects from the bottom of the ice. The time of flight of the pulse would then be calibrated to ice thickness. Acoustic (sonar) systems are not well suited because sound couples inefficiently from air to solids. Resolution would thus be poor unless ultrasonic frequencies were used, in which case too much sound energy would scatter in all directions from ice cracks. Electromagnetic (EM or radiowave) systems are better suited because the energy does couple well from air into non-conducting solids such as ice. Additionally, EM pulses can be made short enough for good resolution without worrying about scattering.

Book excerpt: Sea Ice: Physics and Remote Sensing addresses experiences acquired mainly in Canada by researchers in the fields of ice physics and growth history in relation to its polycrystalline structure as well as ice parameters retrieval from remote sensing observations. The volume describes processes operating at the macro- and microscale (e.g., brine entrapment in sea ice, crystallographic texture of ice types, brine drainage mechanisms, etc.). The information is supported by high-quality photographs of ice thin-sections prepared from cores of different ice types, all obtained by leading experts during field experiments in the 1970s through the 1990s, using photographic cameras and scanning microscopy. In addition, this volume presents techniques to retrieve a suite of sea ice parameters (e.g. ice type, concentration, extent, thickness, surface temperature, surface deformation, etc.) from space-borne and airborne sensor data. The breadth of the material on this subject is designed to appeal to researchers and users of remote sensing data who want to develop quick familiarity with the capabilities of this technology or detailed knowledge about major techniques for retrieval of key ice parameters. Volume highlights include: Detailed crystallographic classification of natural sea ice, the key information from which information about ice growth conditions can be inferred. Many examples are presented with material to support qualitative and quantitative interpretation of the data. Methods developed for revealing microstructural characteristics of sea ice and performing forensic investigations. Data sets on radiative properties and satellite observations of sea ice, its snow cover, and surrounding open water. Methods of retrieval of ice surface features and geophysical parameters from remote sensing observations with a focus on critical issues such as the suitability of different sensors for different tasks and data synergism. Sea Ice: Physics and Remote Sensing is intended for a variety of sea ice audiences interested in different aspects of ice related to physics, geophysics, remote sensing, operational monitoring, mechanics, and cryospheric sciences.
