"> It’s time for calibration.

We spent all day in assembly and calibration.

The Multibeam Echosounder is an acoustic device. It measures the time of acoustic waves travelling into the water column to reconstruct the topography of the seafloor. Data collected allow us to create a digital terrain model of the study site.

The multibeam system works together with a motion sensor, to correct picth, roll and heading of the device, plus a sound velocity profiler, a probe for the calibration of the speed of the acoustic waves into the water.

The assembly and the calibration are delicate and fundamental steps for the success of the field survey.

Motion sensor is .. acting up, but we never give up!
