N2 - In 1995 geophysical investigations in the southern part of the AP-1 geotraverse across the whole Barents Sea Plate were completed. The entire profile links the super-deep SG-3 well on the Kola peninsular (town of Zapolarny) and the base Hayes-1 well on Franz-Joseph Land. The extent of the investigated part of the profile was 700 km. The integrated seismic experiment included offshore and onshore wide-angle reflection/refraction observations (referred hereinafter as Deep Seismic Sounding-DSS) with 3-component ocean bottom seismographs (OBS) and air guns and multi-channel seismic reflection study (MCS) at different offsets ranges. Sufficiently dense deployment of OBS (5-20 km) and a 250 m shooting interval provided reliable phase correlation and wave identification. Intensive reflections from the Moho have been recorded practically continuously along the profile. The DSS data processing built a mid point dynamic reflection Moho image and produced a general depth section. MCS data defined boundaries in the sedimentary layer and the basement surface in the southern part of the profile. The lowermost observed boundary, the Moho, occurs at depths between 35 and 40 km. The thickness of sedimentary cover varies from zero in the southern part of the profile to 14-16 km in its northern part. Results of geological interpretation confirm the continental crust in the studied part of the Barents Sea Shelf Plate.
