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).
Describes the latest remote sensing technologies used to detect ice hazards in the marine environment; map surface currents, sea-state and surface winds; study ice dynamics, over ice transportation, oil spill countermeasures, climate changes and ice reconnaisance. Includes such technologies as acoustic sensing, ice-thickness measurement, passive microwave remote sensing, ground wave and surface-based radars.
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.
