The Polynesien wreck lies at around 65m depth off the coast of Malta in the Mediterranean Sea. It was a French passenger liner launched in 1890 and converted into a warship during World War 1. These wrecks are the supermodels of the underwater world and make for good subject matter to illustrate a point.
Early in 2025, we did a baseline survey of this 150m long WW1 wreck, using our Sonic 2026 multibeam, at 450kHz. We completed 6 passes over the wreck to get as much detail as possible.
Next we went over the wreck again with the Voxometer, in a single pass. The improved result and detail in the data just in one single pass was clearly evident. This result can be attributed to the MA3 Multi Aspect principle whereby the subject is observed from multiple different aspect angles, at different frequencies, and at different times/intervals.
Increased productivity and time saving with Voxometer
With a Voxometer survey system, surveys can be performed at high(er) speed, in a single pass, without compromising the data quality. There are no avoidable data holidays and there is rarely any need to return to site to re-survey an area.
What is clearly evident from this simple survey example, is firstly the improvement in data quality and detail that the Voxometer is able to deliver. Also the fact that this was achieved in a single pass versus 6 passes with the multibeam, translates into a real time saving of around 80%!
So just imagine what the Voxometer can do on your survey project?!
