    In:  Supplement to: Van Autenboer, T; Decleir, H (1978): Glacier discharge in the Sor-Rondane, a contribution to the mass balance of Dronning Maud Land, Antarctica. Zeitschrift für Gletscherkunde und Glazialgeologie, 14(1), 1-16, hdl:10013/epic.40239.d001
    Publication Date: 2023-05-12
    Description: Mass transport and mass flux values for the different types of glaciers in the Sør-Rondane are calculated from computer models, based upon gravity data and geodetic stake velocity measurements. The results are interpreted in the light of a general flow line analysis, glacial geological investigations and of the ablation terms of the mass balance for Dronning Maud Land and Antarctica.

    Description: A numerical glacier model has been developed for Glacier d'Argentiere (France) in order to study its relation with climate and investigate possible causes forthe observed variations in the terminus record since the beginning of the Little Ice Age. At first results are presented from a basic sensitivity investigation,with plots of steady state glacier length versus perturbations in mass balance and glacier reaction with respect to sinusoidal net balance oscillations. An attemptis then made to simulate the historic front variations. The mass balance history of the glacier is constructed assuming a linear relationship with (i) summertemperature anomalies and (ii) mean annual temperature anomalies for Basel dating back to the beginning of the 16th century. Although model run (ii) turnsout to yield better agreement with the observations, both simulations have in common that the observed glacier retreat comes too late. Improved simulationscan only be obtained assuming an additional negative mass balance perturbation of around 0.1 m/year over roughly the last 150 years. These results indicatethat the assumption of a linear relationship between summer temperature and the glacier's mass balance may not be valid anymore when extrapolated to pastenvironments. This might be evidence of additional micrometeorological and glacier surface conditions prevailing in valleys at maximum glacier extent, thatare not absorbed well in the climatic records.

    Description: This paper reviews the physical background of Energy Balance Climate Models and evaluates the use of Sellers' and North's model in simulating the present climate. The sensitivity of themodels - with updated empirical constants - is tested for use in the ice-age problem. In this connection the seasonal model of North and Coakley was extended to include a more realisticcontinent-ocean distribution. A simulation of the temperature field with a full-size Northern hemisphere continental ice sheet proved to be in fair agreement with palaeoclimatic proxy data.

    Description: Ice thickness measurements, carried out by radio echo sounder and gravimeter in the central part of the Sor Rondane Mountains, reveal a subglacial topography of the outlet glaciers and itstributaries characterized by U-shaped valley profiles and overdeepened bedrock. Mass-flux measurements highlight the reduced flow of at least one glacier (Jenningsbreen). This glacier isin the process of being cut off from the main ice supply and may serve as an example for the deglaciation process. An interesting feature of this deglaciation is that, once decoupled from themain ice supply, this glacier is probably characterized by an increased lowering of the ice surface gradient due to the ablation which is characteristic for the upper part of the present outletglacier. In the end this will result in a southward flow of which examples can be found elsewhere in the mountains. On the basis of the field evidence a numerical flow line model ispresented to simulate the behaviour of the outlet glaciers of the central part of the mountains during the last glacial maximum. These experiments show an increase of 300-400 m in icethickness under realistic assumptions for mass balance, temperature and sea level. Some of the higher glacial levels are then attributed to an environment characterized by a higheraccumulation predating the last glacial maximum.

    Description: Summer party of the 31st Japanese Antarctic Research Experdition (JARE-31) carried out maintenance of automatic meteorological stations, glaciological observation, and drilling test for"Antarctic Climate Research (ACR)" project from late December 1989 to January 1990 around the Soer Rondane Mountains region. This party is constituted by four glaciologists includingtwo Belgian observers and one JARE-30 member.Three prototypes of electromechanical ice drill for deep core sampling using antifreezing liquid were successfully tested on a bare glacier at Jenningsbreen. On the same glacier, dynamicsof glacier movement were studied by Belgian observers. Mass balance measurement were conducted on Goosenbreen of Brattnipane.Two helicopters were employed for geological and topographical survey in the Soer Rondane region, so that we were able to fly to Nansenisen, south of Soer Rondane, and to obtainsurface bare ice within dust band (volcanic ash?).

    Description: Morainic deposits found above the present glacier surface in the central Sor Rondane Mountains give evidence of former glaciations. In this paper, an attemptis made to interprete these observed glacier fluctuations in terms of environmental change. To do this, a numerical flowline model, taking into accountthermodynamics and a coupled ice shelf, has been developed and is applied to two outlet glaciers through the mountain range, Gunnestadbreen andJenningsbreen. It is found that lower ice temperatures accompagned by a reduced accumulation, further enhanced by a drop in sea level corresponding totypical glacial conditions account for a 150 - 200 m rise in glacier level. From a comparison of these results with palaeogeographical reconstruction for a'maximum' glacial stage for Jenningsbreen by Hirakawa et al. (1989) it is argued that their morainic deposits relate to an earlier Cenozoic glaciation involvinga full grown ice sheet.
