We studied the Cenozoic sedimentary cover on the basis of data of continuous seismic profiling (CSP) carried out in 2003–2004 in the White Sea in the course of comprehensive geophysical investigations by the Marine Arctic Geological Expedition (MAGE). Judging from the wave pattern, bedding, and availability of unconformable surfaces, the deposits are subdivided into separate seismoacoustic complexes (SC).
