Satellite multichannel passive-microwave sensors have provided global radiance measurements with which to map, monitor, and study the Arctic and Antarctic polar sea ice covers. The data span over 18 years (as of April 1997), starting with the launch of the Scanning Multichannel Microwave Radiometer (SMMR) on NASA's SeaSat A and Nimbus 7 in 1978 and continuing with the Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave/Imager (SSMI) series beginning in 1987. It is anticipated that the DMSP SSMI series will continue into the 21st century. The SSMI series will be augmented by new, improved sensors to be flown on Japanese and U.S. space platforms. This User's Guide provides a description of a new sea ice concentration data set generated from observations made by three of these multichannel sensors. The data set includes gridded daily ice concentrations (every-other-day for the SMMR data) for both the north and south polar regions from October 26, 1978 through September 30, 1995, with the one exception of a 6-week data gap from December 3, 1987 through January 12, 1988. The data have been placed on two CD-ROMs that include a ReadMeCD file giving the technical details on the file format, file headers, north and south polar grids, ancillary data sets, and directory structure of the CD-ROM. The CD-ROMS will be distributed by the National Snow and Ice Data Center in Boulder, CO. Cavalieri, Donald J. and Parkinson, Claire L. and Gloersen, Per and Zwally, H.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 68. Human activities in the polar regions have undergone incredible changes in this century. Among these changes is the revolution that satellites have brought about in obtaining information concerning polar geophysical processes. Satellites have flown for about three decades, and the polar regions have been the subject of their routine surveillance for more than half that time. Our observations of polar regions have evolved from happenstance ship sightings and isolated harbor icing records to routine global records obtained by those satellites. Thanks to such abundant data, we now know a great deal about the ice-covered seas, which constitute about 10% of the Earth's surface. This explosion of information about sea ice has fascinated scientists for some 20 years. We are now at a point of transition in sea ice studies; we are concerned less about ice itself and more about its role in the climate system. This change in emphasis has been the prime stimulus for this book.

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.

Antarctica is no longer a 'pole apart'. From a scientific perspective, the Antarctic ice sheet, ocean and climate systems are intimately linked with the global climate and are now seen to be of international significance for understanding climate change. From an economic perspective, the Antarctic is perceived to have great potential as a source of marine resources although the extent of speculated mineral and hydrocarbon resources is unknown. From a conservation perspective, the continent of Antarctica represents the ideal image of unspoiled wilderness. Antarctic Environments and Resources is an accessible and timely new geography of the Antarctic which examines the differing and sometimes conflicting interests in the great southern continent, the Southern Ocean and the subantarctic islands against a background of the physical and natural systems of the region and their interactions. It charts the development of human involvement in the area, focusing on the exploitation of resources from early sealing to modern fisheries, tourism and science, and it assesses the consequent impacts on the natural environment. The text also reviews the emerging framework for future environmental management developed under the Antarctic Treaty System. This is an ideal text for undergraduates studying glacial geomorphology, environmental management, polar regions and the Antarctic.

This timely book presents a wide-ranging review of Arctic environmental change in response to global warming, and gives a broad insight into the transformation of the Arctic which we can expect during the next century. It is in high northern latitudes that we can expect to observe global warming at its most powerful, making it a natural laboratory where climate changes and their impacts can be monitored and studied more readily than elsewhere in the world. Fourteen authoritative reviews cover the predictions of warming rates by General Circulation Models; variabilities in atmospheric circulation and moisture flux; the dynamics of the polar vortex in the Arctic and its role in ozone loss; the countervailing influence of air pollution in reducing solar irradiance; and the impact of climatic change on Arctic terrestrial and marine ecosystems. Also detailed are the thermohaline circulation of the ocean, the extent and thickness of sea ice, the sizes of glaciers and ice sheets, and the extent of permafrost. Moving to past changes, the records from Greenland ice cores and deep ocean drilling are reviewed for what they tell us about past climates and glaciation in the Arctic., The book paints a vivid and disturbing picture of the enhanced warming that can be expected in the Arctic relative to lower latitudes, and of the major impacts that this will have on the northern cryosphere. It will be an invaluable reference for anyone seeking a greater understanding of the factors and processes affecting the arctic environment, which may ultimately have a major impact on global climatic change.
