Map of Cordilleera Real Nord (Illampu)

Glacier maps 1 : 50000 exist of the glaciers around lllampu (6368 m) from surveys in 1928, 1963 and 1975, of the glaciers of IIlimani (6420 m) in 1975 and 1983, respectively. From these maps glacier changes 1928 - 1963 - 1975 - 1983 have been evaluated. Their retreat is smaller than that of corresponding glaciers in the Eastern Alps. The alpine advance that has begun in the sixties was not observed in the Cordillera Real.

Geological map of SIRINUTEN, Heimefrontfjella, Antarctica (Scale 1:25,000)

Topographic data of this geological map were obtained through stereoscopic aerial photo interpretation. The photogrammetric photo flights were undertaken in 1986 by the Institut für Angewandte Geodäsie, Frankfurt. Horizontal ground control points required for aerial photo interpretation were determined by means of Doppler satellite observation during the 2nd German Neuschwabenland Expedition 1985/86. Vertical ground control points were taken from unpublished map drafts at 1:100 000 scale by Norsk Polarinstitutt, Oslo. The elevation above mean sea level was transferred to Heimefrontfjella barometrically. For this reason assertions concerning the absolute elevation (referred to sea level) are uncertain. Contours and spot heights presented on the map were obtained from the photogrammetric evaluation of the photography taken in 1986; relative elevation data (hight differences) are accurate to approximately ±10 m.

Geological map of northern XU-Fjella, Heimefrontfjella, Dronning Maud Land, Antarctica (Scale 1:25,000)

The geological map shows the northeastern part of the polyphase deformed Sivorg Terrane in the Heimefrontfjella/Dronning Maud Land. The basement was affected by late Mesoproterozoic and Cambrian deformation and metamorphism. Geological mapping was carried out during the Antarctic Expedition 2000/01 of the Alfred Wegener Institute for Polar and Marine Research. Topographic data were obtained through stereoscopic aerial photo interpretation. The photogrammetric photo flights were undertaken in 1986 by the Institut für Angewandte Geodäsie, Frankfurt/M. Horizontal ground control points required for aerial photo interpretation were determined by means of Doppler satellite observation during the 2nd German Neuschwabenland Expedition 1985/86.

Geological map of HANSSONHORNA, Heimefrontfjella, Dronning Maud Land, Antarctica, 2nd revised Edition (Scale 1:25,000)

The geological map shows the border area between the polyphase (late Mesoproterozoic and Cambrian) deformed Sivorg Terrane and the Kottas Terrane where a pervasive Cambrian tectonometamorphic overprints is lacking. Geological revision mapping was carried out during the Antarctic Expedition 2000/01 of the Alfred Wegener Institute for Polar and Marine Research.

Map of Lewis-Glacier - Mt. Kenya 1983 (pdf 600 kB)

In February of 1983 a new terrestrial photogrammetric survey of Lewis Glacier (0° 9' S) has been made, from which the present topographic map has been produced in a scale of 1:5000. Simultaneously a survey of 1963 was evaluated giving a basis for computations of area and volume changes over the 20 year period: Lewis Glacier has lost 22 % of its area and 50 % of its volume. Based on maps and field observations of moraines 10 different stages were identified. Changes of area and volume can be determined for the periods after 1890, two older, undated stages are presumed to be of Little Ice Age-origin. Moderate losses from 1890 to 1920 were followed by strong, uninterrupted retreat up to present. In this respect Lewis Glacier behaves as all other equatorial glaciers that were closer examined. Compared to alpine glaciers the development was similar up to 1950. In the following years, however, the glaciers of the Alps gained mass and advanced while Lewis Glacier experienced its strongest losses from 1974 to 1983.
