英文摘要	The main results of the radio-echo sounding and reflection seismic soundings in the area of Pionerskoe Subglacial Lake, East Antarctica have been discussed. The radio-echo sounding data were collected during the fieldworks of 49-51 Russian Antarctic Expeditions (2003-2006). These investigations were aimed at studying the subice relief and subglacial lakes. The ice thickness of the area varied from 1450 to 2450 meters. The bedrock elevation was between from 300 to 1300 meters. The rose-diagram has been calculated on the basis of bedrock grid. It demonstrates six main directions of the morphological structures in the area: 65-245°, 10-190°, 30-210°, 115-295°, 145-325° ? 160-340°. One reflection seismic sounding was carried out in the field season of the 53rd Russian Antarctic Expedition (2007/08). According to this data, the depth of Pionerskoe Lake is about 30 m. The bottom of the lake is covered by about 300 m thick sediments.
