    In: Research report / Cold Regions Research and Engineering Laboratory, 30
    Description / Table of Contents: Summary: Deformations occurring in a tunnel, two trenches, and a 30 m deep pit excavated in the Greenland névé in the summer of 1954 have been measured over a period of 2 years. The experimental results indicate that closure rates increase with lateral distance from a restraining boundary up to distances of about 1 m. At larger distances, the effect of the boundary is not appreciable. Closure rates for deep excavations are not found to be strongly depth-dependent. This is due to a roughly parallel increase of viscosity and pressure with depth. Vertical compaction results from the pit agree well with those calculated from the depth-density relation using Sorge's Law. A theoretical calculation for the tunnel and pit closure, which is a modification of existing theories for the deformation of an elastic, compressible, thick-walled cylinder, is in fair agreement with the observed deformations. From this agreement it appears that the flow behavior of the névé can be described on the basis of a Newtonian viscosity. The trench closure is described as the-squeezing out of horizontal layers, fixed at some distance from the trench, and modified only slightly by the drag of neighboring layers. Measurements will be continued during future summers.

    Description / Table of Contents: Summary: Experiments have been carried out on the plastic deformation of thick-walled snow-ice cylinders under hydrostatic pressure as a function of pressure and temperature. At constant circumferential stress and temperature the natural strain rate of closure is a constant. This constant varies with the circumferential stress according to a sine function and is exponentially dependent on temperature with an energy of activation of 14.1 kcal/mole at an average circumferential stress of 3.1 kg/cm^2. The mechanism of the plastic flow is in agreement with a mechanism proposed previously, that is, flow between grain boundaries takes place.

    Description / Table of Contents: Summary: A simple theory is proposed for crack formation and development by soil desiccation on the basis of laboratory experiments utilizing soil samples (Bloomington till) with max particle size of 1 mm diam. held in flat wooden containers. The crack pattern is more dependent on the thickness of the soil sample than on temperature or humidity. Some effect is caused also by differences in the bottom material of the containers. The area of cells made by crack patterns has a log normal size distribution. Total length of cracks decreases with increase in sample thickness. The number of sides of cells also depends on the thickness. Cracking was found to begin from the center of the soil layer and to propagate to the surface or bottom with non-uniform speed.

    In: Research report / Cold Regions Research and Engineering Laboratory, 78
    Description / Table of Contents: Summary: This climatological study makes use of the temperature, wind, and precipitation records from 12 stations on the Greenland Ice Sheet. Many of these stations were not in operation for concurrent periods and records for a year or more were available from only a few of them. The mean, mean maximum, mean minimum, absolute maximum, and absolute minimum temperatures were computed from the records. The highest absolute maximum temperature reported was 44°F at Mint Julep in southwestern Greenland. The lowest absolute minimum was -94°F at Northice in northern Greenland. This study shows that the prevailing wind usually was from the direction of the high central area of the ice sheet. Stations on the west slope had prevailing winds with an easterly component whereas stations on the east slope had prevailing winds with a westerly component. The wind speed varied from 0 to approximately 60 kt, but was predominantly in the 0 to 20 kt range. At some of the stations on the ice sheet, precipitation was measured in precipitation gages, at others it was measured as surface accumulation. At many locations the annual accumulation was determined from stratigraphic studies of the snow profile. The number of days on which snow occurred, expressed as percent of total days of observation, was used as an index to the amount of snowfall. The mean annual accumulation shows precipitation to be heavier on the west slope of the ice sheet than in other areas. The precipitation records at Northice indicate that the annual precipitation in that part of northern Greenland may be very light. The means for the various climatological parameters covered in this study are presented in tables and on a climatological map which presents a cartographic picture of the overall climatology of the Greenland Ice Sheet.

    Description / Table of Contents: From the Introduction: During the last few years, there has been an increased interest in developing a rational explanation for the rather considerable variation in such bulk properties of sea ice as its strength, density, thermal conductivity, latent heat of melting, and coefficient of thermal expansion. Of these properties, sea-ice strength has received by far the most attention for practical reasons.

    Description / Table of Contents: Summary: A study of how age hardening affects the various mechanical properties of processed snow was made. A description of how the age hardening process is affected by the variables of density, temperature, grain size, and shape is given. An empirical equation relating creep rate to stress, age, and density was obtained. The study also shows that the various mechanical properties are related to age by an exponential function.

    Description / Table of Contents: From the Summary: During the summer of 1960, observations were made of ground fog on the Greenland Ice Cap and of sea fog in the Thule area in northwestern Greenland. A microscope-stage-fog impactor was designed, and its collection efficiency determined both empirically and by computation from the theoretical work of Langmuir and Blodgett (1946). The empirical efficiency was found to be considerably greater than the theoretical efficiency.

    Description / Table of Contents: Summary: The effect of air flow on the thermal conductivity of snow was investigated. Steady-state temperature measurements were made along the edge and axis of a cylindrical bed of snow to determine the effective axial thermal conductivity of snow. Unconsolidated snow samples were used, with densities ranging from 0.376 to 0.472 g/cm^3 and corresponding snow particle sizes of 0.065 to 0.219 cm nominal diameter; the mass flow rates employed ranged from approximately 10-40 x 10^-4g/cm^2 sec. Snow density and sample size apparently have opposite effects on the effective thermal conductivity because of the flow of fluid in snow. The test apparatus is described in detail and is illustrated. The results of the experiments are tabulated, and a least square equation is given which represents the results well.

    Description / Table of Contents: Summary: A principle of particle segregation by freezing is presented. It is demonstrated experimentally by using a transparent freezing cabinet in which a sample of distilled water freezes from the bottom upward. In this way the freezing front line travels vertically and the particles are carried against gravity. By using the same material with different shapes (glass beads and broken quartz or glass) it is demonstrated that an important factor in particle migration is the shape of the particle or its contact area with the interface. By testing other materials with different shapes and sizes, it is demonstrated that another important factor is particle size and rate of freezing. Fine particles migrate under a wide range of rates of freezing; coarser ones migrate at lower and more limited ranges of rates of freezing. It is suggested that, for determining frost behavior of soils in permafrost regions, freezing from the bottom upward is a more reliable test than freezing from the top down. Freezing from the bottom more closely approximates freezing of the active layer above permafrost; also, friction with the cylinder testing wall is eliminated. The implication of this principle in engineering and studies of soil genesis in cold regions is emphasized.

    Description / Table of Contents: Summary: The theory of snow densification is further developed on the basis of an exponential relation between viscosity and density. A linear relation between load-stress and strain rate is not valid for high stresses, and is replaced by a hyperbolic sine function. An empirical function is given for the temperature cycle correction. Two equations are derived for calculating depth-density curves with computers, and a simplified one for use with desk calculators. Instructions are given for determination of function parameters from field data. Four depth-density curves for Greenland and Antarctic locations are computed and graphed to show that the theory is useful.

    Description / Table of Contents: Summary: Various strength properties of naturally compacted high-density snows, in the density range of from 0.40 to 0.75 g/cm^3, are reported. Test results are given for: unconfined compression; unconfined and confined double shear; ring, flexural, and centrifugal tensile strength; torsional shear; and work of disaggregation. The work of disaggregation per unit volume was related to crushing, tensile, and shear strength at various lateral pressures, using the same empirical relationship. The results of the various tests measuring the tensile strength of the snow compare favorably with each other. An attempt was made to use the direct shear strength results in Coulomb’s equation for the determination of Mohr’s envelope of rupture for snow. These tests yield higher values than those obtained in unconfined compression tests. However, angles of internal friction obtained considering Mohr’s envelope to be straight line seem to agree with measurements taken on an unconfined compression specimen.

    Description / Table of Contents: Abstract: Measurements were made of global and net radiation between 6 July and 7 August 1955 at a site on the Greenland Ice Cap located near 78°N latitude and at an elevation of 6800 ft. Snow-surface temperatures during this period were below 0°C and mean cloudiness was 0.7. Total incident global radiation measured during the 33-day period amounted to 20,628 ?? of which only 3059 ??, or about 15%, were absorbed by the snow cover. Most of the absorbed global radiation was re-emitted as long-wave radiation, so the net gain during the observation period amounted to not more than 7.6 ??/day. Diffuse sky radiation amounted to only 19% of all incoming global radiation measured at the ice-cap research site. In the temperate zone, diffuse sky radiation amounts to 30% or more of the incoming radiation. The small amount of diffuse sky radiation indicates low atmospheric turbidity in this polar climatic zone. Incident global radiation was reduced by 6% in the presence of a 0.5 cloud cover. Under full overcast conditions the snow surface received 65% of the global radiation measured on clear days. In the temperate zone as little as 30% of global radiation reaches the earth under full cloud cover. The large amount of global radiation received in the Arctic under full cloud cover is the primary cause of one form of arctic white-out. Accompanying the small decrease in global radiation caused by cloudiness is a large decrease in effective outgoing long-wave radiation, with an increase in the net radiation balance. This condition contributes to a greater potential ablation of the snow and ice cover during cloudy seasons. The long-wave radiation balance at this site on the ice cap was always negative during the period covered by this study. Errors associated with the measurement of solar radiation at the low sun angles which prevailed at the research site were found to be about -3%. No correction was applied to the basic data, however, since there were insufficient data to establish the consistency of this error over the period of observation. During periods of blowing and drifting snow, 6% more global radiation was measured at 1.25 m above the snow surface than at 5.7 m elevation. The increase may be due to multiple reflection within the layer of blowing snow. The atmospheric transmission coefficient at the ice-cap site was found to be 0.968. This high value was associated with the low atmospheric turbidity. The heat balance of the snow cover as computed from the radiation measurements and a temperature profile in the snow was found to be 7.6 ??/day at the ice-cap site. This is a negligible heat gain when compared with the 400 ??/day gain by a spring snow pack in the Sierra Nevada of California. For the entire season when the sun is above the horizon, the estimated net gain by the ice cap is 1000 ??, no more than a 2-1/2-day heat supply used in melting the snow of the High Sierra. Some measurements made with a silicon solar battery similar to those developed by the Bell Telephone Laboratories indicate that it may have a significantly higher efficiency on the ice cap than in the more temperate zone. Verification of this apparent increase in efficiency and the causes for it require further study of the performance of the p-n junction cells in the Arctic.

    Description / Table of Contents: Limited studies of white-outs on the Greenland Ice Cap indicate that five major types of low visibility have been reported as white-out. They are: 1.) Overcast white-out, caused by a continuous cloud cover. 2.) Water-fog white-out, produced by supercooled water droplets in the air. 3.) Ice-fog white-out, produced by ice crystals suspended in the air. 4.) Blowing snow white-out, produced by wind-driven, wind-eroded snow. 5.) Precipitation white-out, produced by falling snow. The first three types are interrelated and appear to be produced by upslope, convective lifting of warm maritime air and the advective transport of the cooled saturated air over the cold snow field. Radiation heat losses from the snow surface may contribute to more rapid formation of the white-out. The fact that there is a shift in the prevailing wind direction prior to the development of a white-out indicates that certain changes in upper air circulation may be associated with white-out formation and duration. There is reason to believe that upper air and surface observations might make it possible to forecast white-outs on the Greenland Ice Cap with some degree of reliability.

    Description / Table of Contents: Summary: Charts of mean annual air temperature and precipitation over the ice cap are constructed on the basis of snow-profile studies at 8 locations, data collected for several years after 1953 at two U.S. Air Force weather stations, and records from expeditions since 1930. The warming trend in the Arctic appears to have occurred to a lesser degree on the ice cap, possibly because of the effect of the snow cover. The lowest mean annual temperature in South Greenland is estimated to occur within the area bounded by the 2500 m contour and the -18°C isotherm; mean annual temperature at 2700 is estimated as -20.9°C. In North Greenland, the mean annual temperature at 1700 m is estimated at -22°C. The presence of ice glands in the snow and daily max summer temperatures, estimated from records of coastal stations, indicate a potentially high incidence of melting at about 1300 m elevation and some melting at 1700 m in North Greenland, and melting up to 2700 m in the South. Annual accumulation is 2-3 times as great at 2500 m on the west side of the ice cap as at the crest. South of 66°N, precipitation may be about twice as great on the east side of the crest as in the west.

    Description / Table of Contents: Summary: The results of studies in the summer of 1957 on ice samples taken from the ice tunnel at TUTO, core samples obtained by drilling in the ice cap at Site 2, and snow samples, using the transverse vibration method and a new portable meter, are reported. Young's modulus was determined from the resonance frequency of flexural vibrations of samples cut in the form of rectangular bars; the loss factor was measured from damping; and the coefficient of viscosity calculated using the Maxwell model. The modulus of elasticity of samples of a density from 0.917 - 0.90 g/cm^3 (tunnel ice) decreased sharply with slight deviations of the density from that of pure ice. At densities from 0.90 - 0.50 g/cm^3 (deep-pit and drill-core samples) the relation between the modulus of elasticity and density was linear, while in the density range from 0.50-0.25 g/cm^3 (surface snow) the modulus of elasticity decreased exponentially. The viscosity-density relation of the samples was similar to that of elasticity vs density. Young's modulus increased slightly with decreasing temperature, while viscosity increased exponentially. The activation energy was calculated as 18.7 kcal/mol for old ice-cap ice, 13.9 kcal/mol for tunnel ice with elongated bubbles, and 13.5 kcal/mol for super-imposed ice.

    Description / Table of Contents: Summary: The study was made in order to simulate the deformation of a tunnel in glacier ice and compare the results with the theoretical value derived from compression or tension tests. The plastic deformation of commercial polycrystalline ice and manufactured snow-ice was determined by measuring the discharge of oil from the cavity of closed hollow ice cylinders subjected to high external pressure in an oil-filled pressure chamber. The deformation vs time curves were similar to those obtained in compression or tension tests. The relationships between minimum strain rate and applied pressure, or between minimum strain rate and the circumferential stress at the surface of the inner cavity, were found to differ from the power law ϵ ̇= ασⁿ, the value of n being an increasing function of stress. Analysis of time deformation curves indicates that viscoelastic models proposed by former investigators do not apply to the mechanism of the plastic deformation of ice.

    Description / Table of Contents: Summary: The results of studies on the physical properties of fog whiteout, as it occurred at Site 2 on the Greenland Ice Cap in the summers of 1956 and 1957, are reported and compared with the results of other studies; the instruments, methods of measurement, and data-reduction techniques used are described; and attempts at dissipating whiteout by AgI (silver iodide) seeding are discussed briefly. Emphasis was given to measurements of fog-particle size distribution, liquid-water content, relative humidity, visibility, and atmospheric nuclei. The data are tabulated. The synoptic situations for 2 selected cases of fog whiteout at relative humidities of less than 100% (possibly because of the presence of salt solutions) are described; and the balance between the rate at which water is made available in the air as it is lifted over the Ice Cap and the rate of water flux to the snow surface is computed using various equations. Efforts at fog dispersal by AgI seeding from the ground were inconclusive.

    Description / Table of Contents: Summary: The results of experiments on the bonding of polished and microtomed surfaces of bubble-free ice samples at -5°C with various loads are reported. Only a small part of the available surface area appeared to be bonded, this area increasing with the bonding load. Surfaces apposed immediately after preparation showed an appreciably higher force of separation than those joined after a time interval. The force of separation for surfaces placed together at 0% relative humidity was higher than that at 100% relative humidity. A simplified theory of bonding of irregular ice surfaces is formulated in the appendix. The calculations are based on the assumption of a distribution of small ice cylinders of equal cross sections but different heights located on a non-deformable plate. The cylinders are deformed by a constant force which is applied by another completely non-deformable flat plate. The deformation as a function of force and time and the force of separation as a function of load are derived, assuming that the distribution of heights is given by a box distribution (i.e., frequency of heights is constant).

    Description / Table of Contents: Summary: The distribution of temperature throughout an idealized ice cap is studied. The idealized ice cap is considered as one with a constant growth rate, without internal movement, subject to a linear climatic change and to a constant geothermal influx. The problem is treated as a Stefan-type problem and the solution is obtained by the principle of superposition. The results indicate that the temperature at the base of the ice cap rises with time and eventually would reach the melting point of the ice. Under such conditions, it is concluded that the ice cap is not resting on a permafrost base as suggested by previous investigation.

The theory could be useful in an analysis of the data obtained from the large number of snow pits in Greenland, Ellesmere Island,and Antarctica.

    Description / Table of Contents: Summary: The theory of a plate on an elastic foundation will closely predict the radial cracks observed in loading tests on floating ice sheets. However, the plate theory does not predict accurately the circumferential crack which forms ultimately with increased loading. The wedge theory is developed in an attempt to better predict the location and magnitude of the stresses causing the circumferential crack. The results obtained can be applied to help predict the ultimate bearing capacity of an ice sheet, provided the modulus of elasticity and flexural strength of the ice are known.

    Description / Table of Contents: Summary: The heat exchange of a snow cover was studied with respect to the effects of heat transfer processes on metamorphic action within the snow cover and the prediction of heat fluxes and the resulting changes in snow cover characteristics from standard meteorological information. Data collected at the USA SIPRE Keweenaw Field Station, Houghton, Michigan, were used to determine heat transfer by thermal radiation, convection, and conduction. The percent of daily incident solar radiation at the outer limits of the earth's atmosphere which reaches the snow surface ranged from 94 with clear skies to less than 20 with an overcast less than 1000 ft high and precipitation. Average diurnal patterns of total solar radiation may be estimated for various cloudiness. Total solar radiation with overcast clouds less than 5000 ft high averaged about 70% of the clear-sky radiation. Atmospheric radiation related to temperatures during clear nights gave a curve paralleling the black body radiation curve, although about 7 ly/hr lower in absolute values. Atmospheric radiation during clear skies was about 9 ly/hr less than that with low overcast conditions with no snow falling. In the presence of falling snow, total hemispherical radiation was about 5 ly/hr greater than with no snow falling but with' similar low overcast cloudiness. With low overcast cloudiness, the net long-wave exchange averaged about -17 ly/day in January and -8 ly/day in February. With clear skies the net long-wave exchange averaged about -128 ly/day in January and -120 ly/day in February. The net radiation exchange with clear skies during midday remained slightly negative in January and became increasingly positive through February. The highest positive values of net radiation occurred during the day with low overcast or broken cloudiness and precipitation. The largest net radiational loss of 9 ly/hr occurred at night with clear skies and nearly calm winds. The average magnitude of surface temperature inversions over snow was related to observations of cloudiness and wind speeds for both day and night. With winds of 12 knots or greater, the temperature difference in the first 10m was usually near adiabatic even with clear skies at night. During the day inversions seldom exceeded 1-2°C, and a slight lapse commonly occurred during low overcast conditions and moderate winds. The Liljequist method for computing turbulent heat transfer and conductive heat transfer in snow was used. Average air temperature is shown to exert a pronounced effect upon snow heat conduction, cold content and temperature profile. Average temperature differences through the snow, responsible for metamorphic action leading to the formation of depth hoar, can be estimated by a knowledge of the previous 20-hr average temperature. Snow hardness distributions, indicators of supporting capacity of snow, can be estimated graphically from snow density and depth observations.

    Description / Table of Contents: В 1960 г. в Канаде состоялся Первый международный симпозиум по геологии Арктики, в котором привяли участие советские, канадские, американские, английские, датские и норвежские ученые. Итогом работ симпозиума явился настоящий сборник, в котором сведены новейшие материалы по геологии, океанологии, гляциологии и климатологии северных полярных областей земного шара. Эти работы дают отчетливое представление о геологическом строении огромных территорий Канады и Аляски, о рельефе и характере осадков два Северного Ледовитого океана, о ледовом режиме Арктики. Необходимо отметить, что до недавнего времени многие области зарубежной Арктики были белыми пятнами на геологических картах; первые сведения о них содержатся в статьях этого сборника. Новые материалы сборника дают ценнейшие сведения для сравнительных оценок геологических условий и обстановки оруденения северных областей советской и зарубежной Арктики.
    Description / Table of Contents: Translation of abstract: In 1960, the First International Symposium on Arctic Geology was held in Canada, in which Soviet, Canadian, American, English, Danish and Norwegian scientists took part. The result of the symposium was this collection, which brings together the latest materials on geology, oceanology, glaciology and climatology of the northern polar regions of the globe. These works give a clear idea of the geological structure of the vast territories of Canada and Alaska, the relief and nature of precipitation in the two Arctic Oceans, and the ice regime of the Arctic. It should be noted that before recently, many areas of the foreign Arctic were blank spots on geological maps; the first information about them is contained in the articles in this collection. New materials in the collection provide valuable information for comparative assessments of geological conditions and mineralization conditions in the northern regions of the Soviet and foreign Arctic.

    Description / Table of Contents: Dieses Werk gibt erstmalig eine geschlossene Länderkunde des Südpolarkontinents und seiner vorgelagerten Inseln nach neuestem Stand, wie sie in solcher Ausführlichkeit einmalig in der bisherigen Literatur ist. In zwölf Abschnitten werden Forschungsgang, Geologie, Vereisung und Klima der Antarktis, die ozeanographischen Verhältnisse der umgebenden Meere, die Lebewelt und die wirtschaftlichen wie politischen Verhältnisse behandelt. Der zweite Teil bietet eine ausführliche regionale Darstellung der einzelnen natürlichen Großräume des Kontinents. Die beigegebenen Karten stellen einen kleinen länderkundlichen Atlas des Gebietes dar, wie er in ähnlicher Form ebenfalls noch nicht existiert. Von besonderer Wichtigkeit sind die Angaben über alle bisher durchgeführten Expeditionen und den Walfang, die Klimatabellen, Listen von Hütten und Leuchtfeuern sowie der beigegebene wissenschaftliche Apparat. Diese Länderkunde ist im Zusammenwirken mit Polarinstituten und Forschern aller an der Antarktis interessierten Länder entstanden und wird sich bei der künftigen Erschließung des Südpolkontinents und den Vorbereitungen für das Geophysikalische Jahr 1957/58 als unentbehrlich erweisen.

    Description / Table of Contents: Summary: The temperature distribution in snow subjected to gamma radiation from an operating nuclear reactor is analyzed mathematically, assuming that the effect of radiation is equivalent to a continuous heat source, the intensity of which is a function of the radial distance from the reactor. Steady-state solutions are derived for two cases: when the radial distance is 13 ft and when it is 19.1 ft. The results indicate that the temperature of the snow in certain regions in the several feet immediately below the foundation will exceed the design limit of 20°F. Increasing the shielding of the reactor will reduce the intensity of the radiation and snow temperature. Other possible ways to reduce the snow temperature include the use of refrigeration coils and the forcing of the atmospheric air through the snow.

    Description / Table of Contents: Summary: The depth-density relationship of the surface snow to 30-ft depth at three locations on the Greenland Ice Cap east of Thule is presented. Rates of accumulation and densification deduced from the pit studies are used in elementary mathematical expressions developed in this report. These expressions describe a densification process applicable to continuously accumulating polar snow, between the depths of 10 and 40 ft. Loads, densities, and rates of densification are presented in relation to depth and time and applied to problems of undersnow military construction.

    Description / Table of Contents: Summary: The law of sliding of ice over bedrock is generalized to include the effect of the presence of a longitudinal stress. The sliding velocity thus depends on both the shear stress acting at the bottom of an ice mass and the longitudinal stress. With this generalized law, it is still possible to make a one-dimensional analysis of the problem of calculating the profile of an ice cap or glacier, such as was carried out by Nye, and yet introduce the effect of large longitudinal stresses. As a result a profile can be calculated with two equations. One equation is applicable to the central region of an ice cap and the other equation (which was found by Nye) is valid elsewhere. By an appropriate joining of the profiles derived from these two equations, the complete profile of an ice cap can be obtained. From two sample calculations it is shown that, for a large ice cap, Nye's theory is valid practically everywhere, and there is no real need to bring in the modification. For a small ice cap, the modification to the profile is valid over an appreciable fraction of the total width of the ice cap. A very simple extension of the analysis of the ice cap profile allows for the effect of isostatic sinking of the bedrock surface under a large ice cap. (An initially flat bedrock surface was assumed. The analysis can be extended easily to allow for an arbitrarily shaped initial bedrock surface.)

    Description / Table of Contents: Laboratory experiments were performed with a specil closed-system side-freezing cabinet in which completely saturated soil samples were subjected to alternate freeze-thaw cycles without surcharge. A vertical or nearly vertical freezethaw plane was obtained in the side-freezing cabinet. The soil used was a straight graded noncohesive material with 14 finer than the No. 200 0.074 mm mesh sieve. According to frost criterion based only on gradation, the soil would be classified as a never frost-heaving moraine soil or non-frost-susceptible. All experiments were run for 20 and 22 cycles. Freezing rates used were as follows 30.0 mmhr 33.0 mmhr and 4 .0 mmhr. The initial dry density was approximately constant for each test at 1.8 gcm3 or 112.4 lbft3, and complete saturation was maintained in the tests.

    Description / Table of Contents: Summary: A new mechanism is described which explains the formation of moraines in the ablation areas of cold ice caps. The mechanism involves the freezing of water onto the bottom surface of an ice cap. This water comes from regions of the bottom surface where the combination of the geothermal heat and the heat produced by sliding of ice over the bed is sufficient to melt ice. A number of criticisms are made of the shear hypothesis, which has been advanced to explain moraines occurring on Baffin Island and near Thule, Greenland. It is concluded that this older hypothesis may be inadequate to account for these moraines. Although in theory the mechanism proposed here undoubtedly would lead to the formation of moraines, the existing field data are insufficient to prove conclusively that actual moraines have originated in this way.

    Description / Table of Contents: Summary: Four ground patterns were investigated by means of trenches cut in the outwash near Thule, Greenland: circular and linear depressions in unsorted material, polygonal troughs in unsorted material, sorted circles, and irregular mounds and depressions of low relief formed in unsorted finer grained material. Correlation is made between surface pattern, grain size and structure of the active layer, and type and distribution of ground ice for the patterns investigated. Classification of the active layer as disturbed, slightly disturbed, and undisturbed is based on the condition of primary depositional bedding and the presence or absence of vertical sorting. Other features of the active layer, depending upon its type, are an accumulation of fines at the bottom of the active layer and on top of stones, and a siliceous calcareous evaporite on the under surface and clean washed coarser particles beneath the larger stones. Fabric analysis of four kinds of ground ice is presented: ice wedge, relict ice, ice mass, and ice lens, as well as analysis of the contact of ice wedges with relict and mass ice. Practical applications, based on the conclusions, are given for the selection of foundation sites and the location of non-frost-susceptible building materials. NOTE: This is a very large file.

    Description / Table of Contents: Summary: Investigations on sea ice at Hopedale, Labrador, March 1956, included: small beam tests and in-place cantilever beam tests for flexural strength; ring tensile-strength tests; unconfined compression tests, with stress-strain studies to determine "Young's modulus"; and double shear tests. The results exhibit a great deal of scatter, primarily due to the inhomogeneity of sea ice. Ring tensile strength values range between 3.3 kg/cm^2 and 22.3 kg/cm2 between -2.5°C and -19.1°C. The small beam tests give flexural strength values from 0.5 to 17.3 kg/cm^2 in a similar temperature range. The in-place pull-up cantilever beam tests give flexural strength values of 2.2 to 4.0 kg/cm^2, with much less scatter. Crushing strength values range from 26.3 to more than 107 kg/cm^2 in the range -4.9°C to -18.3°C. Values for Young's modulus obtained from the slope of the straight line portion of the stress-strain curves in compression ranged between 4520 and 10,225 kg/cm^2. There is a temperature dependence, explained by the effect of change in brine content, on sea-ice structure. The double shear tests give values of 7.8 to 34.2 kg/cm^2 in the range -5.5°C to -12.8°C. These are higher than the tensile-strength values. These failures occurred normal to the direction of growth, while the tensile strength was obtained with failure parallel to it.

    Description / Table of Contents: Summary: The results of a study on the feasibility of mapping selected snow-cover characteristics for military purposes, taking into account both current synoptic and average conditions, are reported in detail. Problems associated with the construction of isolines for depicting individual or combination of snow-cover conditions are discussed; the need for other statistical parameters in addition to the means is stressed; and the adaptation of frequency and variability indices is suggested. The use of a regional technique, which identified areas somewhat homogenous or substantially different from adjacent areas, is investigated. Problems in mapping snow density are also considered as well as the possibility of estimating snow density from meteorological data. Three sets of codes for the systematic recording and transmission of data are proposed, including a code for ground observers, a simplified code for use where no instruments or trained personnel are available, and a code for aerial observations.

    Description / Table of Contents: Summary: Studies were conducted on 58 snow-ice beams (7.5 cm wide, 10.0 cm high, and 56.0 cm long) ranging in density from 0.621 - 0.719 g/cm^3 under varying loads, at uniform loading rates (except for 23 beams which were tested with repeated loading), and at a constant temperature of -5 ± 0.5°C. All beams were tested to failure. The modulus of elasticity of the beams increased with density and loading rate. The modulus of elasticity ranged from 1.35 x 10^4 to 2.22x 10^4 kg/cm^2 for densities of 0.621 - 719 g/cm^3 respectively. A variation in the relative time of deflection from 42 - 23 sec/0.0200 cm gave a variation in the modulus of elasticity from 1.22 x 10^4 to 1.42 x 10^4 kg/cm^2. The modulus of rupture was roughly a linear function of density, increasing from 7.79 - 11.54 kg/cm^2 with density. Failure of the beams was sudden, with a conchoidal fracture occurring in the middle third of the span, and appeared to be a combination of shear and flexure.

    Description / Table of Contents: Summary: Apparatus was built for deforming ice crystals under hydrostatic pressures up to 350 atmospheres. Single crystals were placed in the mounts in such a way that the deformation occurred by gliding on the basal glide plane. It was found that the shear strain rate increased as the pressure was increased at constant temperature, but that the rate is practically independent of hydrostatic pressure when the difference between the ice temperature and the melting point is kept constant.

    Description / Table of Contents: Summary: Laboratory experiments on the air permeability of various screened and natural snows are described, and, results are analyzed to determine whether the parameters obtained from the measurements could be used to define a snow type. The permeability of a snow sample of known porosity (calculated from density) was determined over a wide range of air velocities; the sample was then compacted artificially a few mm, its density was determined, and its permeability measured again. The procedure was used to obtain curves for several densities of the same sample. Air flow appeared laminar for velocities less than 5 cm/sec in fine-grained snow (less than 0.8 mm in diam.), 2 cm/sec in medium-grained snow (0.8-1.2 mm diam.), and 1 cm/sec in larger-grained snow. A formula is presented expressing all of the results obtained under laminar-flow conditions in a single relationship, and an equation for estimating grain size from initial permeability and initial porosity is suggested. Snow conversion tables and a discussion of the effect of varying sample porosity on its permeability are appended.

    Description / Table of Contents: Summary: The results of temperature, density, ram-hardness and grain-size measurements at 118 test sites along a 300-mi. traverse, ranging in elevation from 2000 to 8000 ft, are reported in detail, and their meteorological and climatic implications are discussed. Four types of diagenetically produced facies were recognized: ablation facies, extending from the snout of the glacier to the firn line; soaked facies, extending from the firn line to the saturation line; percolation facies, extending from the saturation line to the dry-snow line; and dry-snow facies, extending across the glacier above the dry-snow line. The well defined saturation line shows marked discontinuities in temperature, density, and ram hardness, while the dry-snow line is a transition 1 zone 10-20 mi. wide. The recognition of facies allows greater resolution of glacier characteristics than Ahlmann's classification, permitting quantitative subdivision of all types of large glaciers. Regional precipitation (entirely from cyclonic storms) is about 5 times greater than at Thule; and the prevailing katabatic winds control the vertical component of the temperature gradient in the snow and firn. The depth density curve of the firn at elevations where melt is negligible is invariant with time, as in Sorge's law, so that the densification can be treated as a steady-state situation with load as the only significant variable.

    Description / Table of Contents: Summary: The compressive strength of snow cylinders was investigated as a function of age of snow, snow-particle size, and age of the cylinders. The effect of gases such as carbon dioxide, methane, and ammonia on the strength of snow cylinders has also been studied. The experimental results show that the older the snow from which snow cylinders are made, the smaller the compressive strength. The compressive strength of cylinders decreases with the snow particle size. An equation describing the aging curves for snow cylinders is presented. Whereas carbon dioxide and methane in small quantities have no effect on the compressive strength, ammonia appreciably lowers the compressive strength of snow cylinders. All strength measurements were carried out at -10°C.

    Description / Table of Contents: Summary: Laboratory experiments on the creep of sifted snow under uniaxial, hydrostatic, and confined-side compressive stresses are described, and the results are discussed on the basis of an additive theory for combined stresses. Stress (4-40 psi) and temperature (-3.6°C to -13.6°C) dependence was investigated for 35 samples (initial density = 0.4 g/cm^3) subjected to uniaxial and hydrostatic stress for 200-sec time increments. Another series of 104 samples (initial densities 0.36-0.63) was subjected to uniaxial, hydrostatic, and confined-side compressive stresses until an arbitrary change in density was reached. In all cases the applied stress ultimately became a shear stress acting between grains, the open structure reacting differently to combined stresses and separate uniaxial stresses. An activation energy of 13,400 cal/mol was obtained from the first group of tests.
