Sound Velocity Correction
SIMRAD EM122 (ALL) No tidal corrections. No filters are used. For the transit towards the working area around the Oceanographer and Hayes Transform Faults no dedicated sound velocity profile has been used. Instead a profile from a previous cruise to the Atlantic Ocean has been used. In the working area a XBT sound velocity profile has been taken at the start of the survey. For the transit back the sound velocity profile from the survey area has been used.
