Multibeam bathymetry data of the western part of the Romanche Trench (Equatorial Atlantic).

We present the multibeam bathymetry data of the western part of the Romanche Trench (Equatorial Atlantic) which is the main natural corridor that regulates inflow of Antarctic Bottom Water into the eastern basin of the Atlantic Ocean. Multibeam bathymetry survey was carried out during the 33 cruise of the research vessel in November 2016. The data were collected using the multibeam echosounder RESON SeaBat 7150 and processed using PDS2000 software.
