Abstract

During the 1989/90 field season on Filchner-Ronne 1ce Shelf (FRIS), Antarctica, special interest was focussed on the examination of the bottom-melting rate by different measuring technigues.Access to the sea water underneath the ice shelf was gained by mcans of hot-water drillings.The installation of ternperature cable and TDR-sensor lines yield a distinct value of the bottom mass-ba1ance parameter after re-measurement in 1992.In addition a seasonal dependence for bottom melting is indicated.The results of the longterm observation conform with a mass-balance study performed in the same region from surface-based measurements in the same season (DETERMANN et al. 1990).The influence oftidal-induced ice shelf/ocean interaction with regard to bottom me1ting can be derived from a continual registration of sea-water temperatures.
