Abstract:

Information concerning the supply area of Morsárjökull, a small outlet glacier of Vatnaöjkull, was derived from a firn profile measured in a pit 6 m. deep.

The conspicuous bulge on the medial moraine is, by extrapolation from the annual movement, attributed to a former glacial recession between 1890 and 1900. This bulge is correlated with discontinuous moraines near the head of Skeidarárjökull.

Moraines indicating a former greater extension of the glacier are mentioned and evidence showing the recent rapid retreat and thinning of the glacier is presented.

ZUSAMMENFASSUNG. Die Kenntnisnahme des samme1gebietes des Morsárjökull, einem kleinen Auslaufgletsche des Vatnajökull, wurde in einer 6 m tiefen Grube gemessenen Firnseite entnommen.

Die an'der Mittel-Moräne sichtbare Aushauchung wird, durch Extrapolation der jährlichen Bewegung, einem ehemaligen Gletscherrückgang zwischen 1890 und 1900 zugeschrieben. Diese Ausbauchung wird mit diskontinuierlichen Moränen nahe dem Auslauf des Skeidaránrjökull in Beziehung gebracht.

Moränen, die auf eine ehemals grössere Ausdehnung des Gletschers hinweisen, werden erwähnt, und der Beweis für den jüngst reissenden Rückgang und Schwund des Gletschers wird dargelegt.
