    Description / Table of Contents: Put as simply as possible, this is a book on Einstein's theory of gravity (general relativity). It is the first textbook on the subject that uses throughout the modern formalism and notation of differential geometry, and it is the first book to document in full the revolutionary techniques developed during the past decade to test the theory of relativity. (Such tests include the use of atomic clocks, long baseline radio interferometry, interplanetary radar, lunar laser ranging, and interplanetary spacecraft.) Among the topics treated in depth are relativistic stars and star clusters and their possible roles in pulsars and quasars, recent developments in cosmology, gravitational collapse and black holes, and the generation, propagation, and detection of gravitational waves. All three authors are uniquely qualified to have written this authoritative work: during the past decade, they and their research groups have been responsible for approximately half of the theoretical developments in the areas of concentration mentioned. Here is a book that is without competition and without peer - a book that belongs on the shelves and in the libraries of all who are seriously interested in modern science.

    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: CONTENTS: Preface. - Nomenclature. - Introduction. - Funicular regime. - Grain growth. - Grain contacts. - Densification. - Pendular regime. - Discussion and conclusions. - Literature cited. - Abstract.
    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 flow of water through layered snowpacks is discussed. A method for predicting flow through unsaturated layers is given. The flow along ice layers and through ice layers is analyzed in terms of the slope, permeability, thickness and length of the layers. It is shown that the permeability of ice layers required to cause large flow diversions is quite small. The effect of slope is large even at small angles.

    Description / Table of Contents: An investigation is made into the determination of the relationship between the extinction coefficient and the salinity of sea ice. A HeNe laser is used to propagate a beam of red light, of wavelength 6328Å, through a series of ice samples at -20°C. The optical extinction coefficients were calculated and plotted against the measured salinities. The results of the experiment indicated an exponential relationship between extinction coefficient and salinity. The relationship may be described by the equation: y = 2.41 + 0.001 exp (1.19x) where y is the extinction coefficient and x is the salinity.

    Description / Table of Contents: Observations made during 1966 - 68 along a 70 km. flow line on the Brunt Ice Shelf are used to show that an average of 1 m. of ice is melted each year from beneath the ice shelf. Appreciable bottom melting occurs at all points along the flow line. Within the limits of observing errors, ice drainage into the ice shelf is found to balance surface accumulation over the catchment area. Particle trajectories indicate that snow falling at the hinge line takes about 190 yr. to reach the ice front and that, because of bottom melting, none of the snow falling at distances greater than 5 km. inland from the hinge line ever reaches the ice front. The high melting rates calculated at all points beneath the Brunt Ice Shelf suggest that bottom melting may be more widespread than previously suspected. The behaviour of the Brunt Ice Shelf is largely influenced by the rapidly moving "Dalgliesh Ice Stream" which supplies the northern part of the ice shelf, where the ice front advances up to 1 - 5 km. each year. Farther,south, ice movement is hindered by the grounded ice of the McDonald Ice Rumples. Between these two zones, large shear stresses have resulted in complete fracture of the ice shelf into isolated blocks separated by expanses of thin ice shelf, sea ice and leads that mark the lines of active separation. Large ice tongues may calve in response to tsunamis with a frequency equal to one of the natural frequencies of the ice tongue. Calving of long narrow ice tongues may be due to the prolonged action of stresses induced by sea currents.

    Description / Table of Contents: A meridian scanning photometric system was designed for the simultaneous observation of the dynamic behavior of the proton and electron auroras with high time resolution. The hydrogen Balmer-beta (H_β) was selected as a typical emission line from proton auroras, whereas N_2+ 4278 Å, OI 5577 Å and OI 6300 Å emissions were selected for electron auroras. The H_β photometer has a so-called tilting filter to measure rapid space-time variations of faint proton auroras free from the contamination of strong electron auroras. The observations were carried out from March to October 1970 at Syowa Station (corrected geomagnetic lat. -66.7°, long. 72.5°) in Antarctica. From the records of the meridian scanning photometers, spatial distributitions of auroral luminosity along the geomagnetic meridian were displayed as a function of local time, and the iso-intensity contour lines were drawn. These space-time diagrams of auroral luminosity were shown to be very useful for the quantitative study of the dynamic behavior of auroras. Using auroral space-time diagrams, the constitution of the proton and electron aurora substorms was described in detail. During the growth phase of a magnetospheric substorm, the emission zone of the proton aurora moves equatorward with a speed of 100-200m/sec, accompanying the development of the asymmetric ring current and the positive H bay in the evening region. The equatorward movement and the growth of the asymmetric ring current were explained by an earthward movement of the ring current protons due to the intensification of the magnetospheric convection and the subsequent energization of protons through the betatron and Fermi acceleration processes. At the onset of the expansion phase, the quiet arcs suddenly brighten in the pre-midnight region, and the electron aurora bulge rapidly expands poleward and westward, whereas in the post-midnight region, the emission zone of proton auroras rapidly expands poleward and eastward with a large increase in luminosity. Proton auroras are absent in the leading edge of the expanding electron aurora bulge, while breakup-type electron auroras (arcs or bands) are not observed in the expanding proton aurora bulge. Therefore, it is suggested that there is a mechanism which accelerates electrons along the geomagnetic field lines from the magnetosphere down to the ionosphere in the pre-midnight region and protons in the postmidnight region. After the onset of the expansion phase, the luminosity of the proton aurora greatly increases, and simultaneously the emission zone expands equatorward in the evening region, accompanying the development of the asymmetric partial ring current and the positive bay. These features can be interpreted by means of the proton injection into the trapping region due to the magnetic collapse in the tail, and the subsequent westward and earthward drift. From the relationship between the movement of the proton auroras and the geomagnetic variation, it is suggested that the positive bay in the evening hours is induced by the eastward current concentrated along the emission zone of proton auroras. The enhancement of the ionospheric conductivity due to the precipitating protons required to excite the observed proton aurora luminosity is estimated to be sufficient for the concentration of the eastward current. A close relationship between the proton aurora and the IPDP event was also observed, indicating proton pitch-angle diffusion due to the ion cyclotron waves.

    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: 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: 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: 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 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: Glaciological studies of the upper 10m of the ice sheet in East Antarctica were made during the JARE South Pole Traverse 1968-1969. The glaciological studies consisted of studies of surface snow and subsurface snow by means of pits as well as analyses of snow cores. Conditions of surface snow such as accumulation, roughness, density and hardness are described in this paper. It is found that the conditions are distinctly different in four regions along the route from Syowa Station to the South Pole, and that they have a close connection with the slope inclination. Relationship between the snow conditions and the slope inclination is discussed in terms of the dependence of wind speed on the slope inclination. Thus, it is concluded that the conditions of surface snow are mainly controlled by wind speed. Measurements of annual snow accumulations disclose that local variations in accumulations take place in a strong wind region, and coincide with local topography of the region. Also, distinct regional differences in accumulations during the summer season are discussed from the differences between cyclonic and anticyclonic precipitations. Studies of subsurface snow in 2m deep pits indicate that regions located in the north and south of 73°S are characterized respectively by compact fine-grained snow and well-developed depth hoar. Analyses of snow cores from the surface to a depth of 10m revealed the distribution of snow density in the upper 10m of the ice sheet along the route from Syowa Station to the South Pole. Regional profiles of snow density at the depths of 5 and 9m were different from those at the surface. This is due to the differences in the mean annual air temperature.
