[en] Cores from three different Atlantic localities (equatorial, Cape Verde Rise and Porcupine Abyssal Plain) are shown to have anomalous high U contents (5-8 ppm total) in sediments laid down doring the last glacial stage (12-24 ky BP). Radiocarbon data demonstrate that the sediments hosting the peak U levels were accumulated at rates similar to those immediately above and below. All the cores exhibit maximum Mn levels, characteristic colour changes, and maximum U levels in the same sequence with increasing depth in core. On the evidence of the similarities between the cores, and pore waster U data from a Porcupine Abyssal Plain site, it is proposed that the authigenic U enrichments are syndiagenetic and possibly active. No correlation is observed between sediment authigenic U and C_org contents. The source of enrichment is bottom water U which has diffused downwards into the sediments to be sorbed at a particular redox level, located 10-30 cm below the oxic/post-oxic boundary marked by the colour change. The magnitude of the enrichments is caused by the persistence of this boundary at a particular level as a result of the decrease in mean sediment accumulation rate between the last glacial stage (5.2 up to at least 19.1 cm ky^-1) and the Holocene (2.2-4.1 cm ky^-1). Similar accumulation rate contrasts are expected to be widespread in the Atlantic, and the implications for previous reported work, particularly from the Mid-Atlantic Ridge, are discussed. (orig.)

[en] Basic formulae and results of glacier physics appearing in glaciology textbooks can be derived from first principles introduced in algebra-based first year physics courses. We discuss the maximum thickness of alpine glaciers and ice sheets and the relation between maximum thickness and length of an ice sheet. Knowledge of ordinary differential equations allows one to derive also the local ice thickness. (paper)

[en] Changes of general area and linear characteristics on all glaciers of North slop of the Zailijskij Alatau are determined in the result of monitoring of large glacier system on the base of repeated cartography with aero-photography use in 1955, 1979, 1990 raper years. General glaciers deviation, its area and volumes cutting down are distinctly revealed. (author)

[en] A multitemporal analysis on the Mount Disgrazia glaciers was performed by using the 1975, 1978 and 1980 MSS Landsat images. On these images the glaciers were completely described in their boundaries and surface features. Fixed structures were used along their boundaries as fiducial points of the ground control table for the multitemporal comparison of the glaciers. This makes it possible to estimate the galcier surface changes due to frontal displacements as well as the changes in the snow-covered area due to the displacements of the snow transient line. The procedure is possible since the recordings of Landsat satellites are continuous in space and time. It gives completeness to the individual data on the glaciers as provided by the field measurements and it makes the management of the water resources possible
