    Description / Table of Contents: 1895 haben Menschen die Antarktis, in der sich 90 Prozent aller Eismassen befinden, zum erstenmal betreten. Von diesem Zeitpunkt an war dieser Kontinent der Schauplatz abenteuerlicher Expeditionen, deren Teilnehmer unvorstellbare Gefahren auf sich nahmen, um ins Innere dieser unendlichen Eiswüste vorzudringen. Nicht wenige Menschen mußten ihren Wagemut mit dem Leben bezahlen. Zu den Opfern, welche die Antarktis gefordert hat, gehört auch Sir Robert F. Scott, der - wie gleichzeitig Roald Amundsen - versuchte, als erster den Südpol zu erreichen. Es war aber beileibe nicht nur der Reiz des Abenteuers, der die Südpolar-Forscher zu ihren Leistungen angespornt hat - mindestens ebenso faszinierend war die Möglichkeit, einen unbekannten Erdteil wissenschaftlich zu untersuchen. Namhafte Forscher vieler Nationen studieren heute die stellenweise über 4000 m dicke Eisschicht, die Bodenbeschaffenheit des unter diesem Eispanzer liegenden Landes, die mysteriösen elektrischen Strömungen in der Ionosphäre, das seltsame Polarlicht, die zahlreichen Fossilienfunde und die antarktische Tierwelt, die den Biologen so manches Rätsel aufgibt. Peter Briggs, der Autor vieler erfolgreicher populärwissenschaftlicher Bücher, folgt in seinem spannenden Bericht nicht nur den Spuren der Antarktis-Pioniere, er legt auch eindrücklich die Forschungsergebnisse aus dem "Laboratorium am Ende der Welt " dar.

    Description / Table of Contents: A finite difference method for predicting the effect of shock waves on a circular cylindrical cavity in elastic-plastic media was studied. A two-dimensional Lagrangean code was found quite satisfactory. Attenuation of the shock waves through the cavity and the deformation of the cavity wall were discussed.

    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: 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.

Arctic surface winds. - Appendix C. Excerpt from Cold Regions Science and Engineering, USA CRREL Monograph I-A3b. - Appendix D. Excerpt from Proceedings of the Arctic Basin Symposium October 1962. - Abstract.
    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 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.

    Description / Table of Contents: A method to assess quickly the insulation effectiveness of buildings using mobile infrared thermography has been developed at USA CRREL. In contrast to the infrared thermography done in Sweden, this method concentrates on obtaining useful data by measuring the outside surface temperature of structures. This report outlines the basic principles involved in these measurements, and discusses field measurements and the inherent advantages of infrared thermography. Typical thermograms are presented in the appendixes.
