Mutlibeam echosounder (MBES) data and sediment thickness mapping results from the sub-bottom profiler (SBP) data in the Chukchi Rise, Arctic Ocean

The subbottom profiler (SBP) and multibeam echo sounder (MBES) data were densely collected in the Chukchi Rise during the IBRV Araon Arctic Expeditions from 2012 to 2019. These data were used for a high-resolution seismostratigraphic and morphobathymetric analysis of the seabed and seafloor on the northwestern Chukchi margin. The sediment thickness were produced by mapping the major seismostratigraphic unit boundaries using the SBP data.
