Multibeam bathymetry processed data (Kongsberg EM 122 entire dataset) of RV METEOR during cruise M86/1c
Bathymetry data was acquired during R/V METEOR cruise M86/1c in the Northeast Atlantic between 06.12.2011 and 23.12.2011. The main aim was the calibration of the EM122 at Gettysburg seamount.

Description of the data source: During the M86/1c cruise, the hull-mounted KONGSBERG EM122 multibeam echosounder (MBES) was utilized to perform bathymetric mapping in medium to deep waters.

For further information on the system, consult https://www.km.kongsberg.com/. The position and depth of the water column is estimated for each beam by using the detected two-way-travel time and the beam angle, ray-traced through the water column, utilizing a proper sound speed profile.
