During the 1981 field season on the Nordbogletscher, South Greenland, a fim core of almost 19 m was recovered (R. J. B. & P. c.) and isotopic analyses of the resulting samples were made at the geophysical Institute, University of Copenhagen (H. C.). The collection of such a core represents a modest first venture by the GGU into a new fieId. However, some findings have emerged which are interesting both in connection with the Johan Dahl Land project (Clement, 1981) and the long-term programme of modelling glacier hydrology (Braithwaite, 1981).
