This paper presents the results of geomorphological investigations in the area of Ebba Glacier. A granulometric characteristic is presented of some types of deposits localised both within the glacier and in its forefiels. Some complexes of glacial forms were distinguished, on the basis of which an attempt was made to establish the chronology of events responsible for the development of Ebba Valley. Their preliminary analysis permitted the hypothesis of the Wiirm glaciation of the valley and of the four — fold advancement of Holocene glaciers to be set.

This article presents characteristics of the Quaternary deposits and landforms of Ebbadalen, the Nordenskióldbreen foreląnd and the Wordiekammen massif on the basis of geomorphological mapping of this area and a number of geologic profiles A—L studied in detail. Glaciers were much more expanded during the Pleistocene than they are nowadays. Over a period referred to by the present authors as the Petuniabukta-Adolfbukta Stage they occupied the whole Ebbadalen area and the eastern part of Adolfbukta. Marine terraces of 70- 80, 60—65 and 50—55 m a.s.l. were formed earlier. At the turn of the Pleistocene three marine terraces were produced at 40—45, 30—35 and 20—25 m a.s.l. Throughout the Early Holocene transgression (the Ebbadalen Stage = the Thomsondalen Stage) glaciers occurred in nearly the entire Ebbadalen area and occupied a larger part of Adolfbukta than nowadays. During the Middle and Late Holocene marine terraces of 12—15, 5—8, 3—4 and 1—2 m a.s.l. were initiated. Two more glacier advances, the later relating to the Little Ice Age, took place during the Late Holocene
