Utilizing a seismoacoustic complex for the study of the upper sedimentary stratum and seafloor relief in East Arctic

The paper describes a high-resolution seismoacoustic complex for studying the upper sedimentary stratum and seafloor relief. The described complex was used during the 57th cruise of the R/V Akademik M.A. Lavrent’ev in the East Siberian and Laptev seas in the autumn of 2011. The combination of an SES-2000 narrow-beam parametric subbottom profiler and a Gidra 250/500 sidescan sonar has enabled obtaining a series of unique data on the structure of the sedimentary layers and the seafloor relief.
