abstract: <strong class="journal-contentHeaderColor">Abstract.</strong> The accelerated ice flow of ice streams that reach far into the interior of the ice sheets is associated with lubrication of the ice sheet base by basal meltwater. However, the amount of basal melting under the large ice streams â such as the Northeast Greenland Ice Stream (NEGIS) â is largely unknown. In situ measurements of basal melt rates are important from various perspectives as they indicate the heat budget, the hydrologica
