Summary
Six ice cores were collected during the 1997/1998 summer season along the 2000 m contour of Wilhelm II Land (ASAC 2085), followed by fifteen cores the following season from the 1800, 1500 and 1000 m contours in the same area (ASAC 1109), forming a database of twenty cores of approximately 5 m length, and one 10 m core at the automatic weather station site (Mt. Brown South). Each core was analysed for seasonal variability through measurements of density, oxygen isotope ratios, hydrogen peroxide and electrical conductivity records. The information from these cores also allows a preliminary assessment of the patterns of snow preservation and the potential to extract records of environmental and climate variability in a region where this is relatively unknown. The quality of the records found in these cores varied, however the interpretations of accumulation rates made from these cores agree well with previous work in nearby areas. The spatial distributions of accumulation, surface density, and oxygen isotope ratios are presented as contour maps in this report, and recommendations are made for further chemical analysis of the cores, and site selection for deeper drilling in the future.
