    Description / Table of Contents: The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. The volume addresses the following major topics: research results in observing aspects of the Arctic climate system and its processes across a range of time and space scales; representation of cryospheric, atmospheric, and oceanic processes in models, including simulation of their interaction with coupled models; our understanding of the role of the arctic in the global climate system, its response to large-scale climate variations, and the processes involved.

    Description / Table of Contents: Antarctica is the coldest and driest continent on earth - a place for adventure and a key area for global science. Research conducted in this extreme environment has received increasing international attention in recent years due to concerns over destruction of the ozone layer above it and the problems of global warming and rising sea levels. Data collected in the Antarctic now informs a wide range of scientific fields. A record of the globe's climate is locked up in its deep snow and ice while, as part of the early supercontinent Gondwana, its rocks have much to teach us about the geological history of the earth. Adiversity of unique plants and animals abound in Antarctic waters and the clear skies overhead allow astronomers to probe the outer reaches of the universe. Governed internationally since 1959, the Antarctic is also an object lesson in collaboration between nations. This dramatically illustrated new book brings together an international group of leading Antarctic scientists to explain why the Antarctic is so central to understanding the history and potential fate of our planet. It introduces the beauty of the world's greatest wilderness, its remarkable attributes, and the global importance of the international science done there. Spanning topics from marine biology to space science, this book is an accessible overview for anyone interested in the Antarctic and its science and governance. It provides a valuable summary for those involved in polar management and development of new research programmes, and is an inspiration for the next generation of Antarctic researchers.

    Description / Table of Contents: The Arctic is subject to growing economic and political interest. Meanwhile, its water and climate systems are in rapid transformation. Relevant and accessible information about water and climate is therefore vital to detect, understand and adapt to the changes. This thesis investigates hydrological monitoring systems, climate model data, and our understanding of hydro-climatic change, for adaptation to water system changes in the Arctic. Results indicate a lack of harmonized water chemistry data, which may impede efforts to understand transport and origin of key waterborne constituents. Further development of monitoring cannot rely only on a reconciliation of observations and projections on where climate change will be the most severe, as they diverge in this regard. Climate model simulations of drainage basin temperature and precipitation have improved between two recent model generations, but large inaccuracies remain for precipitation projections. Late 20th-century discharge changes in major Arctic rivers generally show excess of water relative to precipitation changes. This indicates a possible contribution of stored water from permafrost or groundwater to sea level rise. The river contribution to the increasing Arctic Ocean freshwater inflow matches that of glaciers, which underlines the importance of considering all sources when assessing change. To provide adequate information for research and policy, Arctic hydrological and hydrochemical monitoring needs to be extended, better integrated and made more accessible. This especially applies to hydrochemistry monitoring, where a more complete set of monitored basins is motivated, including a general extension for the large unmonitored areas close to the Arctic Ocean. Improvements in climate model parameterizations are needed, in particular for precipitation projections. Finally, further water-focused data and modeling efforts are required to resolve the source of excess discharge in Arctic rivers.

    Description / Table of Contents: Once ice-bound, difficult to access, and largely ignored by the rest of the world, the Arctic is now front and center in the midst of many important questions facing the world today. Our daily weather, what we eat, and coastal flooding are all interconnected with the future of the Arctic. The year 2012 was an astounding year for Arctic change. The summer sea ice volume smashed previous records, losing approximately 75 percent of its value since 1980 and half of its areal coverage. Multiple records were also broken when 97 percent of Greenland's surface experienced melt conditions in 2012, the largest melt extent in the satellite era. Receding ice caps in Arctic Canada are now exposing land surfaces that have been continuously ice covered for more than 40,000 years. What happens in the Arctic has far-reaching implications around the world. Loss of snow and ice exacerbates climate change and is the largest contributor to expected global sea level rise during the next century. Ten percent of the world's fish catches comes from Arctic and sub-Arctic waters. The U.S. Geological Survey estimated that up to 13 percent of the world's remaining oil reserves are in the Arctic. The geologic history of the Arctic may hold vital clues about massive volcanic eruptions and the consequent release of massive amount of coal fly ash that is thought to have caused mass extinctions in the distant past. How will these changes affect the rest of Earth? What research should we invest in to best understand this previously hidden land, manage impacts of change on Arctic communities, and cooperate with researchers from other nations? The Arctic in the Anthropocene reviews research questions previously identified by Arctic researchers, and then highlights the new questions that have emerged in the wake of and expectation of further rapid Arctic change, as well as new capabilities to address them. This report is meant to guide future directions in U.S. Arctic research so that research is targeted on critical scientific and societal questions and conducted as effectively as possible. The Arctic in the Anthropocene identifies both a disciplinary and a cross-cutting research strategy for the next 10 to 20 years, and evaluates infrastructure needs and collaboration opportunities. The climate, biology, and society in the Arctic are changing in rapid, complex, and interactive ways. Understanding the Arctic system has never been more critical; thus, Arctic research has never been more important. This report will be a resource for institutions, funders, policy makers, and students. Written in an engaging style, The Arctic in the Anthropocene paints a picture of one of the last unknown places on this planet, and communicates the excitement and importance of the discoveries and challenges that lie ahead.

    Description / Table of Contents: THE FACE OF THE EARTH - The Legacy of Eduard Suess ist ein posthumes Buch vom "Vater der modernen Geologie" Eduard Suess. Viele seiner bahnbrechenden, wissenschaftlichen Thesen haben heute noch Gültigkeit, er prägte Begriffe wie Atmosphäre, Hydro-, Litho- und Biosphäre oder Tethys und Gondwana-Land. Eduard Suess war nicht nur ein Pionier der Geowissenschaften sondern auch ein Vorreiter innovativer Ideen als Politiker. Er initiierte eine weltweit beispielhafte Wasserversorgung einer Großstadt, die 1. Wiener Hochquellenwasserleitung, oder die Donauregulierung in Wien, geplant und ausgeführt als eine natürliche Schutzvorrichtung vor Überschwemmungen. Zum 100. Todestag des Kosmopoliten - er wurde in England geboren, lebte in Prag und Wien und forschte auf der ganzen Welt - am 26. April 2014 setzt "The Face of the Earth" ein Zeichen. Zitate aus der Feder des exzellenten Schreibers Eduard Suess , wissenschaftliche reflektierende Texte von einigen der besten Geologen der Gegenwart und faszinierende Bilder von einem der renommiertesten Fotografen machen das Buch zu einer würdigen Hommage.

    Description / Table of Contents: "It is increasingly clear that the world of climate politics is no longer confined to the activities of national governments and international negotiations. Critical to this transformation of the politics of climate change has been the emergence of new forms of transnational governance that cut across traditional state-based jurisdictions and operate across public and private divides. This book provides the first comprehensive, cutting-edge account of the world of transnational climate change governance. Co-authored by a team of the world's leading experts in the field and based on a survey of sixty case studies, the book traces the emergence, nature and consequences of this phenomenon, and assesses the implications for the field of global environmental politics. It will prove invaluable for researchers, graduate students and policy makers in climate change, political science, international relations, human geography, sociology and ecological economics"--

    Description / Table of Contents: CONTENTS: Introduction. - The ice/ice interface. - The ice/air interface. - The silicate/water/silicate interface. - The silicate/water/ice interface. - Summary. - Literature cited. - Abstract.
    Description / Table of Contents: Interfacial regions in frozen soils are of the following types: ice/ice (grain boundary) ice/water/air, silicate/water/silicate (interlamellar) and silicate/water /ice (extralamellar). For the last, the mid-portion of the interfacial region should be regarded as a liquid-like solution of the ionic and undissociated substances sorbed by the interface and expelled from the ice during freezing. The interfacial forces operative in these regions result in distinct differences in the properties and behavior of the interfacial water, compared with water in bulk; but, in spite of strong interfacial forces, the interfacial water exhibits liquid-like mobility in its response to many kinds of driving forces. From the evidence and arguments considered, it is concluded that distinctly different zones of orientational order can be distinguished within the interfacial regions. For an advancing silicate/water/ice interface it is proposed that there is a zone of strong perturbation and disorder immediately proximate to silicate surfaces in which the protons of water molecules are partially delocalized; this makes them more easily dissociated. Two or three molecular diameters removed from the silicate surface the interfacial forces operative there combine to create a zone of enhanced order in the molecular configurations. At some farther distance, depending upon the temperature below freezing, it is suggested that there exists a disordered transition zone proximate to the ice surface as portrayed in Drost-Hansen's model. It is suggested that future investigations will contribute refinements in the model and will uncover still further complexities in the various interfaces mentioned.

    Description / Table of Contents: An infinite plate on an elastic foundation is considered for a uniform load distributed over a circular area. The analysis of the problem is based on three-dimensional theory of elasticity. A numerical evaluation for the critical stress is made assuming a bending type of failure and the results closely agree with Westergaard's equations.

    Description / Table of Contents: Decoding the complete history of Earth and our solar system requires the placing of the scattered pages of Earth history in a precise chronological order, and the 40Ar/39Ar dating technique is one of the most trusteddating techniques to do that. The 40Ar/39Ar method has been in use for more than 40 years, and has constantlyevolved since then. The steady improvement of the technique is largely due to a better understandingof the K/Ar system, an appreciation of the subtleties of geological material and a continuous refinement ofthe analytical tools used for isotope extraction and counting. The 40Ar/39Ar method is also one of the mostversatile techniques with countless applications in archaeology, tectonics, structural geology, orogenic processesand provenance studies, ore and petroleum genesis, volcanology, weathering processes and climate,and planetary geology. This volume is the first of its kind and covers methodological developments, modelling,data handling, and direct applications of the 40Ar/39Ar technique.

    Description / Table of Contents: An investigation was conducted to determine the effect of a compressive stress on the tensile strength of bubbly polycrystalline ice. One hundred forty-five tests were made in an apparatus of novel design. A cylindrical dumbbell specimen was stressed in axial tension and radial and tangential compression by a hydraulic system which minimized bending stresses. Compression-tension ratios ranging from 0.21 to 10.14 were used for the tests. Tensile strength was found to decrease with an increase in the ratio. At the ratio of 3.155 the tensile strength is about one third the uniaxial value. The test results support the evidence that the Brazil test underestimates the tensile strength for ice. They also indicate that the Brazil test value for ice can be no greater than one third the uniaxial tensile strength. A comparison of the experimental results with a few prominent biaxial failure theories indicates a lower tensile strength than predicted by any theory. However, the best approximation to the results is the Coulomb-Mohr criterion.

    Description / Table of Contents: Two holes were drilled through the Greenland ice sheet during 1973 and temperature measurements were made in one hole drilled during 1972. These measurements show that the area of liquid water beneath the ice cap extends to ice depths as shallow as 100 m. The consequences of removing the frozen margin of glacial ice could be serious and more temperature measurements are needed to exactly locate the subglacial water. Petrographic studies of a few ice cores revealed a strongly oriented crystal fabric and an appreciable surface accumulation of superimposed ice.

    Description / Table of Contents: Clay mineral and soil samples were subjected to neutron activation analysis in order to identify and measure the abundances of trace elements having radionuclides with long half-lives. After exposure of cadmium-shielded samples to neutrons for a period of five days, the gamma radiation associated with the decay of the resulting radionuclides was observed using a high resolution Ge(Li) detector. Trace elements identified without prior chemical separation using the gross gamma-ray spectra included Fe, Zn, Ti, Ni, Co, Cr, Sr, Ba, Ca, La, Eu, Tb, Hf, Ta, Th, and U. It should be possible to determine quantitatively the amount of each of these elements. This is a considerable improvement over the number of elements determined in soils previously by activation analysis without destructive chemical treatments.

    Description / Table of Contents: The temperature structure of Post Pond, a small (46.6 hectares), mid-latitude, dimictic lake in west-central New Hampshire, was studied during autumn,winter and spring of 1968-1969. The lake was instrumented over its maximum depth (11.7 m) with a string of 24 thermocouples which recorded hourly temperatures. Temperatures in 9 m of sediments underlying the lake were measured with a thermistor probe. Secondary and tertiary thermocline development in the epilimnion occurred during short warming periods in the early autumn. The autumn overturn lasted 25 days, whereas the spring overturn lasted only 4 days. The entire lake mixed isothermally in the autumn to 3.2°C. During the period of ice cover, the lower 5 m of water gained approximately 51.5 cal/cm^2, which was supplied by stored heat in the bottom sediments. A steady-state thermal gradient of 0.07°C/m was found for the deeper sediments underlying the lake during ice cover. Late winter cooling of bottom water under the ice cover may be the result of snowmelt in areas adjacent to the lake causing activation of groundwater influx. Melting of the clear ice portion of the ice cover was primarily the result of heat supplied to the lake from snowmelt water, and occurred on the underside of the ice sheet. Thermal instability of the water mass persisted for 9 days during peak snowmelt runoff; this can be partially explained by an increase in dissolved solids with depth.

    Description / Table of Contents: Wave propagation generated by vibratory load on a homogeneous, isotropic, linear viscoelastic half-space is studied. The effect of a single concentrated force and a group of forces applied over a circular area has been examined and solutions of the displacement functions are presented. In the case of the group forces, the three types of force distribution used by Reissner and Sung were employed. At a great distance (far field) from the applied load, surface displacements are reduced to closed form expressions. A field method based on these results is recommended for determining the complex modulus and the damping property of a viscoelastic material. For areas near the source (near field), numerical procedures were employed to evaluate the integral solution. To facilitate the application, two simplified versions are provided for calculating the center displacement under the load. They both provide good approximation to the integral solution and, most important of all, they speed up the computation enormously

    Description / Table of Contents: Radical differences in the crystal structure and fabrics of glacier ice cores at Byrd Station and Little America V, Antarctica, are attributed to gross differences in the thermal and deformational histories of the ice at these two locations. At Byrd Station the mean size of crystals increased more than sixfold between 65 m and the bottom of the drill hole at 309 m. Crystal size was also found to increase linearly with the age of the ice, thus simulating isothermal grain growth in metals. However, this growth was not accompanied by any dimensional orientation of crystals or entrapped bubbles, or by any significant increase in the degree of preferred orientation of crystallographic c-axes. These observations imply that negligible shearing is occurring in the top 300 m of the thick grounded ice sheet at Byrd Station. By contrast very considerable deformation is indicated for the floating 258-m-thick Ross Ice Shelf at Little America. This deformation is characterized by the widespread occurrence of "strained" crystals below 65 m, the existence of elongated oriented bubbles between 95 m and 130 m and the attainment of pronounced crystal orientation (multiple-maxima fabrics) by 100-m depth. Exaggerated growth of crystals below 150 m is attributed to increasing temperatures in the ice shelf. The crystal structure of these cores clearly demonstrates that glacial ice only is present in the Ross Ice Shelf at Little America V.

    Description / Table of Contents: Annual degree-day summations over bases of 43°F and 50°F in 15-day periods from May through August are given for the period of record for five interior Alaska climatic stations. Average temperature and precipitation data are included. Patterns of summer temperature in interior Alaska are analyzed in terms of historical, elevational and areal differences. Since 1900, summer temperatures show little long-term change but significant short-term changes. In contrast, winter temperatures show considerable fluctuations, which are reflected in mean annual temperatures to a much greater degree than are summer temperature fluctuations. Average summer lapse rates for the 1600 to 3300 and 3300 to 6600-ft levels were 3.4 and 3.7°F/1000 ft, respectively, based on timberline temperature observations and on upper air data from Fairbanks. Correlation analysis of daily and monthly average July temperatures indicates areas of uniformity with respect to temperature variation. This provides information on lowland climatic stations that are representative of highland locations, especially the Yukon-Tanana Uplands

    Description / Table of Contents: A sea ice terrain model, based upon previously tested height and spacing distributions for sea ice pressure ridging, is developed. Using this model, and additional information on pressure ridge extents, a trafficability model for vehicles traversing the pack ice is developed. Both analytic and Monte Carlo calculations of vehicle trafficability, measured in terms of the average ratio of the total distance traveled over a straight-line distance, are performed. The calculations include cul-de-sacs due to ridge intersections. The trafficability ratio is given as a function of ridge-height-clearance ability of the vehicle and of ridging parameters which may be obtained from laser profiles of the arctic pack ice. Results are in good agreement with simulated routes through sea ice terrain taken from aerial photo mosaics. Contour plots of ridging parameters taken from laser profilometry are also supplied. These plots, together with the trafficability model, supply mobility information for the whole of the western portion of the Arctic Basin.

    Description / Table of Contents: The growth of ice crystals as a function of depth and time in polar firn and glacier ice has been investigated at a number of locations in Antarctica and Greenland. Thin sections of snow and ice were used to measure crystal size variations which showed, in all cases, that crystal size increases essentially linearly with the age of samples. Crystal growth rates are strongly temperature dependent. At Camp Century, Greenland, where the firn temperature is -24°C, crystals grow approximately 23 times faster than at Plateau Station, Antarctica, where the in situ temperature is -57°C. Extrapolation of the existing data indicates that crystal growth rates in polar firn and ice could be expected to vary by about two orders of magnitude over the temperature range -60°C to -15°C. Examination of the changes in the pore-crystal structure relationships to a dpeth of 100 m at Camp Century shows that these changes closely resemble those occuring in the full-scale isothermal sintering of powder compacts.

The ice sheet is assumed to be an isotropic, elastic, thin plate extending to infinity. The water is assumed to be inviscous, incompressible, and of a constant depth. The dynamic equations describing this ice-water system are solved for the steady state solution. Both a concentrated load and a uniform load distributed over a circular area are considered. The velocity which causes resonance is determined. The deflection and stress directly under the load are numerically evaluated.

    Description / Table of Contents: Murry Salby's new book provides an integrated treatment of the processes controlling the Earth-atmosphere system developed from first principles through a balance of theory and applications. This book builds on Salby's previous book Fundamentals of Atmospheric Physics. The scope has been expanded to include climate, while streamlining the presentation for undergraduates in scinece, mathematics, and engineering. Advanced material, suitable for graduate students and researchers, has been retained but distingushed from the basic development. The book offers a conceptual yet quantitative understanding of the controlling influences integrated through theory and major applications. It leads readers through a methodical development of the diverse physical processes that shape weather, global energetics, and climate. End-of-chapter problems of varying difficulty develop student knowledge and ist quanitative application, supported by answers and detailed solutions online for instructors.

    Description / Table of Contents: Contents: Chapter 1: Introduction to the Cryosphere. - Chapter 2: Material Properties of Snow and Ice. - Chapter 3: Snow and Ice Thermodynamics. - Chapter 4: Seasonal Snow and Freshwater Ice. - Chapter 5: Sea Ice. - Chapter 6: Glaciers and Ice Sheets. - Chapter 7: Permafrost. - Chapter 8: Cryosphere-Climate Processes. - Chapter 9: The Cryosphere and Climate Change.
    Description / Table of Contents: The cryosphere encompasses the Earth's snow and ice masses. It is a critical part of our planet's climate system, one that is especially at risk from climate change and global warming. "The Cryosphere" provides an essential introduction to the subject, written by one of the world's leading experts in Earth-system science. In this primer, glaciologist Shawn Marshall introduces readers to the cryosphere and the broader role it plays in our global climate system. After giving a concise overview, he fully explains each component of the cryosphere and how it works - seasonal snow, permafrost, river and lake ice, sea ice, glaciers, ice sheets, and ice shelves. Marshall describes how snow and ice interact with our atmosphere and oceans and how they influence climate, sea level, and ocean circulation. He looks at the cryosphere's role in past ice ages, and considers the changing cryosphere's future impact on our landscape, oceans, and climate. Accessible and authoritative, this primer also features a glossary of key terms, suggestions for further reading, explanations of equations, and a discussion of open research questions in the field.

    Description / Table of Contents: This is the first textbook to address all the components of the Earth's cryosphere - all forms of snow and ice, both terrestrial and marine. It provides a concise but comprehensive summary of snow cover, glaciers, ice sheets, lake and river ice, permafrost, sea ice and icebergs - their past history and projected future state. It is designed for courses at upper undergraduate and graduate level in environmental science, geography, geology, glaciology, hydrology, water resource engineering and ocean sciences. It also provides a superb up-to-date summary for researchers of the cryosphere. The book includes an extensive bibliography, numerous figures and color plates, thematic boxes on selected topics and a glossary. The book builds on courses taught by the authors for many decades at the University of Colorado and the University of Alberta. Whilst there are many existing texts on individual components of the cryosphere, no other textbook covers the whole cryosphere.

    Description / Table of Contents: This revised and updated edition focuses on constrained ordination (RDA, CCA), variation partitioning and the use of permutation tests of statistical hypotheses about multivariate data. Both classification and modern regression methods (GLM, GAM, loess) are reviewes and species functional traits and spatial structures are analysed. Nine case studies of varying difficulty help to illustrate the suggestes analytical methods, using the latest version of Canoco 5. All studies utilise descriptive and manipulative approaches, and are supported by data sets and project files available from the book website: http://regent.prf.jcu.cz/maed2/. Written primarily for community ecologists needing to analyse data resulting from field observations and experiments, this book is a valuable resource for students and researchers dealing with both simple and complex ecological problems, such as the variation of biotic communities with environmental conditions or their response to experimental manipulation.

    Description / Table of Contents: CONTENTS: Introduction. - Field sites and procedures. - Results. - Discussion. - Conclusions. - Literature cited. - Appendix A: Tabulation of AIDJEX core data. - Appendix B: Tabulation of average salinity/ice thickness data. - Abstract.
    Description / Table of Contents: The salinity distribution in multiyear sea ice is dependent on the ice topography and cannot be adequately represented by a single average profile. The cores collected from areas beneath surface hummocks generally showed a systematic increase in salinity with depth from 0 0/00 at tne surface to about 4 0/00 at the base. The cores collected from areas beneath surface depressions were much more saline and displayed large salinity fluctuations. Salinity observations from sea ice of varying thicknesses and ages collected at various arctic and subarctic locations revealed a strong correlation between the average salinity of the ice, S, and the ice thickness, h. For salinity samples collected from cold sea ice at the end of the growth season, this relationship can be represented by two linear equations: S = 14.24 - 19.39h (h? 0.4 m) ; S = 7.88 - 1.59h (h 〉 0.4 m) . It is suggested that the pronounced break in slope at 0.4 m is due to a change in the dominant brine drainage mechanism from brine expulsion to gravity drainage. A linear regression for the data collected during the melt season gives S = 1.58 + 0.18h. An annual cyclic variation of the mean salinity probably exists for multiyear sea ice. The mean salinity should reach a maximum at the end of the growth season and a minimum at the end of the melt season.

    Description / Table of Contents: One of the difficulties that have hampered the development of the mathematical theory of soil plasticity was recently overcome by Mandl and Luque. They showed that the non-coaxiality of the principal axes of a stress tensor and a strain-rate tensor can occur only in plane deformation. Their assumption that the angle of non-coaxiality should be a material constant cannot be supported, however. The angle of noncoaxiality should be determined so that the solution to the given problem can exist. It is demonstrated in one of the examples in this paper that a well-known solution in which the angle of non-coaxiality is assumed to be zero does violate the assumed boundary condition. The theory was reorganized bv using new insights given by Mandl and Luque. It is concluded that still missing is one condition that enables us to determine the angle of non-coaxiality as a function of space.

    Description / Table of Contents: Two compressed air systems for glaciating supercooled clouds were studied in the laboratory. The first system used the sudden expansion of compressed air and was found to be most efficient at 27 psig producing an average of 5.2 x 10^8 ice crystals per cm^3 of air. The second system used a continuous flow of air through nozzles of various designs, of which the supersonic nozzle was found to be the most efficient, producing a maximum of 2.5 x 10^8 crystals per cm^3 of air at 27 psig. The above data were obtained at an ambient temperature of -4°C, but data for other temperatures and pressures were obtained and are presented in the text.

    Description / Table of Contents: The most common example of the application of inclined loads to the soil is the plate-grouser. This consists of a strip footing with a vertical arm at one end. The most usual loading arrangement is one in which a fixed vertical load is applied and then the horizontal load is increased until failure occurs. A theory has been developed which will predict the maximum horizontal force, assuming that the soil is dense enough to be reasonably described by the Coulomb equation. The theory is based on slip line fields including wedges of soil that are not failing. These slip line fields vary systematically with the interface angle [Beta] and the angle of internal shearing resistance of the soil [Phi] and they are a function of the direction of motion of the interface [Theta]. A computer program is provided which will solve the problem directly if the direction of motion [Theta] is given. It will also solve the more practical situation described above by an iterative procedure. The postulated slip line fields have been shown to be correct by means of glass box photographs giving excellent agreement with the theory. The predictions of passive pressure have been verified by a series of force measurements on quite large grousers driven into saturated clay, dry sand and an intermediate loam.

    Description / Table of Contents: The internal friction of single-crystal ice has been attributed to reorientation of the water molecule under periodic stress. However, the theory for damped dislocations, which offers another mechanism for the internal friction of ice, has not been investigated. The effects of scratching the surface of 41 ice samples and X-irradiating and plastically deforming them were evaluated. The effects observed on the internal friction of pure, single-crystal ice, in the flexure mode of oscillation between 400 and 1400 Hz, supported the existence of a dislocation-controlled mechanism, with the drag produced by the interaction of the dislocation with the protons in the crystal. In addition, analysis of the detailed shape of the data curve showed two peaks of tan delta as a function of temperature. The second peak, which had not been previously reported, had an activation energy of 0.16 eV and a relaxation time of 1.7 x 10^8 sec at infinite temperature. These experiments indicated that both peaks vrere controlled by the dislocation mechanism described above.

    Description / Table of Contents: Numerical differentiation by use of classical interpolation formulas yields a diversity of results. Consistent numerical differentiation can be performed by using a spline function as an interpolating function. As an application, temperature observed in a lake is numerically differentiated as a function of time and of depth by use of cubic splines. The deviation of the actual heat transfer mechanism from vertical heat conduction can thus be detected. The reliability of numerical differentiation by spline functions is manifest in this example.

    Description / Table of Contents: Hugoniot curves were generated from simultaneous measurements of shock and free-surface velocities, obtained from samples of frozen Fairbanks (Fox) silt, using the exploding wire technique. The abrupt change in slope of the Us-Up Hugoniot is indicative of a phase change. The shape of the P-V Hugoniot suggests that the transformation begins immediately but does not go to completion. This means that, although the pressure lies slightly above the Rayleigh line through the mixed phase region, the slope does not increase as rapidly as it would if the material had stayed in the initial phase.

    Description / Table of Contents: Detection of mines, explosives, and tunnels may be accomplished by sensing associated volatile effluvia. This investigation was undertaken to provide a basis for predicting the diffusion of volatile compounds from underground sources into the atmosphere. Diffusion of a volatile compound was studied for a range of soil conditions utilizing soils from the mine detection sites in Puerto Rico. A new mathematical analysis based on the Monte Carlo method was developed for predicting vapor diffusion through soil into the atmosphere. It was determined that diffusion in soil can be reliably predicted if soil porosity, moisture content, and affinity for the compound are known. Appearance in the atmosphere is also dependent on accumulation of the compound in air at the soil/atmosphere interface. Diffusion of volatile compounds through soil into the atmosphere is not likely to be an important factor in tunnel detection due to depth of overburden. However, adsorption of compounds at tunnel walls is likely to significantly reduce the amount of vapor appearing in the atmosphere through entrances and vents. Detection in the atmosphere of TNT vapor from mines and explosives buried in moist, porous soil should be possible under ideal sample collection conditions.

    Description / Table of Contents: Two radiochemical methods were investigated for determining the cation exchange capacity of earth materials having a wide range in physicochemical properties. The first method attempted was unsuccessful but involved determination of the radioactivity of a 22Na-NaOAc solution in isotopic equilibrium with a Na+-saturated mineral phase. The logic of this method is presented in order to illustrate principles of isotopic exchange in mineral systems. The method finally adopted is based upon determination of the radioactivity of a salt-free, Na+-saturated mineral sample prepared using a radioactive NaOAc solution with a known 22Na-NaOAc composition. This method is less time-consuming and more accurate than the conventional ammonium acetate method for cation exchange capacity determinations.

    Description / Table of Contents: The solution for the vibration of an elastic plate floating on water is developed. The water is assumed to be incompressible and to have irrotational flow. In free vibration upon release of the plate, the maximum negative rebound of the deflection is 25%. For forced vibration, the steady state part of the solution shows that there is a frequency at which the deflection is a maximum. The stresses become a maximum at a frequency higher than the one for deflection. These critical frequencies depend upon the plate's characteristic length and the depth of the water. For most situations the critical frequency for stress is less than 0.2 cycle per second. At this critical frequency the stresses are amplified over the static case by a factor less than 10%.

    Description / Table of Contents: Low temperature differential thermal analyses of selected clay-water systems were made to locate important phase change temperatures and to define fruitful temperature-pressure fields for precise calorimetric investigation. In addition to an exotherm corresponding to initial freezing, one, two or three exotherms were observed between -35°C and -60°C. The low temperature exotherms do not depend critically upon water content, but clearly they are related to clay mineral and exchangeable cation type. The evolution of heat in this temperature range probably corresponds to a phase change in the interfacial water.

    Description / Table of Contents: This book presents an innovative new approach to studying source mechanisms of earthquakes, combining theory and observation in a unified methodology, with a key focus on the mechanics governing fault failures. It explains source mechanisms by building from fundamental concepts such as the equations of elasticity theory to more advanced problems including dislocation theory, kinematic models and fracture dynamics. The theory is presented first in student-friendly form using consistent notation throughout, and with full, detailed mathematical derivations that enable students to follow each step. Later chapters explain the widely-used practical modelling methods for source mechanism determination, linking clearly to the theoretical foundations, and highlighting the processing of digital seismological data. Providing a unique balance between application techniques and theory, this is an ideal guide for graduate students and researchers in seismology, tectonophysics, geodynamics and geomechanics, and a valuable practical resource for professionals working in seismic hazard assessment and seismic engineering.

    Description / Table of Contents: Cosmogenic radionuclides are radioactive isotopes which are produced by natural processes and distributed across the earth. Utilizing a holistic approach to the environment, the authors show how cosmogenic radionuclides can be used to trace and to reconstruct the history of a large variety of processes. They discuss the ways in which cosmogenic radionuclides can assist in the quantification of complex processes in the present-day environment. The book aims to demonstrate to the reader the strength of analytic tools based on cosmogenic radionuclides, their contribution to almost any field of modern natural science, and how these tools may assist in the solution of many present and future problems that we face here on earth. The book provides a comprehensive discussion of the basic principles behind the applications of cosmogenic (and other) radionuclides as environmental tracers and dating tools. Following the introduction, the second part of the book provides basic information on the origin, properties, and time variability of cosmic radiation, and the concepts, terminology and formulate that will be used in the later chapters. The third part discusses in detail the production of radionuclides by cosmic radiation, their transport and distribution in the atmosphere and the hydrosphere, their storage in natural archives, and how they are measured. The fourth part of the book presents a number of examples selected to illustrate typical tracer and dating applications in a number of different contexts (atmosphere, hydrosphere, geosphere, biosphere, solar physics and astronomy). At the same time the authors outline the limitations of the use of cosmogenic radionuclides. Written on a level accessible to graduate students without specialist skills in physics or mathematics, the book addresses a wide audience, ranging from archaeology, biophysics, and geophysics, to atmospheric physics, hydrology, astrophysics and space science.

    Description / Table of Contents: This report presents the results of a study performed on the behavior, particularly the deformation, of snow under a load applied to a rigid plate at a constant rate of penetration. The results will eventually be used in the development of design criteria for snow roads, runways, and foundations in the polar regions. The tests were conducted on snow samples having a high width/length ratio, simulating a two-dimensional case. The effect of snow density, plate size, and pressure on the deformation of snow below the load was investigated. The pressure-sinkage relationships and the bearing strength as functions of density were also investigated. It was determined that density, in the range 0.3 to 0.6 g/cm^3, can be used as a reasonably reliable index for predicting deformation and behavior of snow under load. In general, the critical pressure (bearing strength) increased as a power function of density, and critical sinkage decreased as a power function of density. It was also observed that the deformation bulb resembled the typical Boussinesq stress bulb. The experimental pressure-sinkage relationships agreed closely with recently developed theoretical values. For the range of plate sizes used, the test data did not provide conclusive evidence of the effect of plate size on deformation and bearing capacity of snow. The possibility of using the Moire fringe method for determing deformation patterns in snow and soils under various loading conditions should be investigated.

    Description / Table of Contents: Experiments by Smith-Johannsen on the adhesion of ice frozen from a number of 1 x 10^-3 ? electrolyte solutions to a wax-treated aluminum surface at -10°C are discussed. It is concluded that the adhesive strength measured by the force per square centimeter needed to shear the ice off the substrate surface is mainly due to a liquid interfacial solution layer between the ice and the substrate surface. The thickness of such a layer is largely determined by the same considerations as the thickness of grain boundary layers in ice obtained from dilute electrolyte solutions.

    Description / Table of Contents: Grain growth, bond growth and densification of wet snow are described in terms of the distribution of equilibrium temperature in the snow matrix. At high water saturations the equilibrium temperature increases with grain size; hence, small particles melt away as large particles grow. Melting also occurs at the intergrain bonds, causing a low strength and rapid densification. At low saturations the equilibrium temperature is determined by the capillary pressure and the particle sizes have only a second order effect. Therefore, grain growth proceeds slowly and, even at large overburden pressures, no intergrain melting occurs. At low saturations the water "tension" acts through a finite area, thus large attractive forces exist between the grains, and the strength of the snow matrix is large.

    Description / Table of Contents: The Marcona Corporation and Kryolitselskabet ?resund, A/S (a Danish corporation) are cooperatively investigating the possibility of developing an open-pit mine along the edge of the Greenland Ice Cap. The response of the glacier to a sudden change in surface slope and thickness is calculated. The existing flow is diverted away from the mineral deposit but will increase when the excavation begins. It is calculated that 66 million cubic meters of ice must be removed in order to establish a stable profile beyond the pit. An additional 7.9 million cubic meters of ice must be removed yearly in order to maintain the profile.

    Description / Table of Contents: Prevailing monthly and seasonal surface wind directions were obtained from 1) weather records for 21 coastal stations around the Arctic Ocean and 2) a series of U.S. Navy wind charts for 15 to 20 locations in the arctic marginal seas and the ocean's interior. This information was combined and analyzed to develop 2 charts which depict the surface flow of air in these areas during the mid-summer and mid-winter months. Since the ice floe stations used in the offshore wind analysis are not permanently located, the Arctic Ocean was selectively divided into 6 zones. Three of these zones separate Polar regions north of 84°N latitude, and 3 other zones each separate the seas bordering the north coasts of Europe, Siberian Russia and North America. Except for a few stations where wind directions are apparently controlled by local influences the results showed the following mid-winter patterns: 1) a near anticlockwise flow within the circle north of 75°N, 2) winds from the north in and near the Chukchi and Bering Seas, 3) northeast winds along the Alaskan coast and northwest along the Canadian Archipelago Islands, and 4) southwest and southeast winds along the northern coasts of Europe and Asia respectively. Although the wind directions during mid-summer become more variable the study showed that the prevailing surface winds for most areas in this season are nearly opposite those observed in winter.

    Description / Table of Contents: The results of a four-summer (1964-1967) hydrologic study of the watershed of Glenn Creek, about 8 miles north of Fairbanks, Alaska, in the Yukon-Tanana uplands physiographic province, are presented. This work was initiated to provide initial baseline hydrologic data for a small subar ctic watershed, the first of its kind in North America. Standard hydrologic and meteorologic instrumentation was used, and streamflow characteristics were analyzed by standard hydrograph-analysis techniques. The stream is second-order, and drains an area of 0.70 square mile. Basin elevations are from 842 ft to 1618 ft. In regard to topography, geology, soils, permafrost, vegetation, and climate, the watershed seems to be representative of low-order, low-elevation drainage basins in the province. Analysis of rainfall-runoff data indicates that about half the 12.3-in. normal annual precipitation is runoff. The remainder is the actual evapotranspiration , which equals only about 30% of estimated potential evapotranspiration. For individual storms, runoff/rainfall proportions were from 0.03 to 0.42 and were positively correlated with antecedent discharge of the stream, which is a measure of watershed wetness. The stream responds rapidly to rainstorms except when the basin is very dry, and has markedly slow recessions compared with temperate region streams of similar size. Rate of recessions is apparentlv controlled by concurrent evapotranspiration rates. Analysis of hydrographs and knowledge of the physical characteristics of the basin indicate that storm runoff occurs initially as surface runoff from bare soil areas adjacent to the stream, while recessions are dominated by a combination of tunnel flow beneath moss-covered parts of the basins and typical groundwater flow through the moss and soils. Peak discharges for individual storms could be well estimated by an equation including antecedent discharge, total precipitation and storm duration, and average recession constant. These results represent the first detailed hydrologic data from the discontinuous permafrost zone of the North American taiga and should be of significance to the International Hydrological Decade and International Biological Program.

    Description / Table of Contents: Pollen analysis and radiocarbon dating of lake sediment cores from four localities in the Frederikshåb district, South-West Greenland, provide a chronology of vegetation changes in the area since c. 1000 B. P. An initial pioneer phase with the early development of some heath communities followed by a mid postglacial phase in which there is the successive appearance of woody scrub species. A final phase shows the decline of some of these. This is interpreted as a general response to a broad amplitude fluctuation in climate, with its optimal period lying between c. 7600 and 3200 B.P. The detailed composition of the vegetation however is influenced by immigration phenomena, with the appearance of many species lagging behind the attainment of their climatic tresholds. Detailed consideration is given to the possibility of Alnus crispa being present as a scrub component during the climatic optimum.

    Description / Table of Contents: Shell-bearing marine sediments in the Nordre Strømfjord area belong to two lithofacies, calcareous sandy gravels and calcareous muddy sands, and to four biofacies comparable to modern communities and related to the sediment lithology: epifaunal benthic and infaunal benthic facies, a current reworked 'mixed' facies and a Portlandia - Propeamussium facies. Radiocarbon dates on nine samples provide a poorly defined model of the glacio-isostatic emergence of the region. The implications of such models and their physical validity are considered in the context of these and other data, and it is suggested that curves for uplift deceleration are a useful means of obtaining the exponential constant k.

    Description / Table of Contents: Measurement Methods in Atmospheric Sciences provides a comprehensive overview of in-situ and remote sensing measurement techniques for probing the Earth's atmosphere. The methods presented in this book span the entire range from classical meteorology via atmospheric chemistry and micrometeorological flux determination to Earth observation from space. Standard instruments for meteorological and air quality monitoring methods, as well as specialized instrumentation predominantly used in scientific experiments, are covered. The presented techniques run from simple mechanical sensors to highly sophisticated electronic devices. Special emphasis is placed on the rapidly evolving field of remote sensing techniques. Here, active ground-based remote sending techniques such as SODAR and LIDAR find a detailed coverage. The book conveys the basic principles of the various observational and monitoring methods, enabling the user to identify the most appropriate method. An introductory chapter covers general principles (e.g. inversion of measured data, available platforms, statistical properties of data, data acquisition). Later chapters each treat methods for measuring a specific property (e.g. humidity, wind speed, wind direction). Long chapters provide an introductory tabular list of the methods treated. More than 100 figures and 400 references, mostly to the recent scientific literature, aid the reader in reading up on the details of the various methods at hand. Recommendations at the end of each major chapter provide additional hints on the use of some instruments in order to facilitate the selection of the proper instrument for a successful measurement. A large number of national and international standards, providing precise guidelines for measuring and acquiring reliable, reproducible and comparable data sets are listed in the appendix. A dedicated index allows easy access to this valuable information. The book is of interest to undergraduate and graduate students in meteorology, physical geography, ecology, environmental sciences and related disciplines as well as to scientists in the process of planning atmospheric measurements in field campaigns or working with data already acquired. Practitioners in environmental agencies and similar institutions will benefit from instrument descriptions and the extended lists in the appendix.

    Description / Table of Contents: The polar regions have experienced some remarkable environmental changes in recent decades, such as the Antarctic ozone hole, the loss of large amounts of sea ice from the Arctic Ocean and major warming on the Antarctic Peninsula. The polar regions are also predicted to warm more than any other region on Earth over the next century if greenhouse gas concentrations continue to rise. Yet trying to separate natural climate variability from anthropogenic forcing still presents many problems. This book presents a thorough review of how the polar climates have changed over the last million years and sets recent changes within a long term perspective, as determined from ice and ocean sediment cores. The approach taken is highly cross-disciplinary and the close links between the atmosphere, ocean and ice at high latitudes are stressed. The volume will be invaluable for researchers and advanced students in polar science, climatology, global change, meteorology, oceanography and glaciology.
