Abstract. The 79° North Glacier (Nioghalvfjerdsbrae, 79NG) is one of three remaining glaciers with a floating tongue in Greenland. Although the glacier was considered exceptionally stable in the past, earlier studies indicate that the ice tongue has thinned in recent decades. By …

Abstract. The Dome Fuji (DF) region in Antarctica is a potential site for an ice core with a record of over one million years. Here, we combine the internal airborne radar stratigraphy with a 1-D model to estimate the age of basal …

Abstract. We present a 1D numerical model which calculates the age of ice around Dome C. It accounts either for melting or for a layer of stagnant ice above the bedrock, depending on the value of an inverted mechanical ice thickness. It …

Abstract. Ice shelves play a key role in the stability of the Antarctic Ice Sheet due to their buttressing effect. A loss of buttressing as a result of increased basal melting or ice shelf disintegration will lead to increased ice discharge. Some …

Abstract. Basal melt of ice shelves is a key factor governing discharge of ice from the Antarctic Ice Sheet as a result of its effects on buttressing. Here, we use radio echo sounding to determine the spatial variability of the basal melt …
