Kongsberg Maritime EM302

EM302 is a multi-beam depth finder for the deep sea. suwasu sounding to depth of the water 7000m is possible, and the measurement is possible by width of up to 8,000m. In this way, except the particularly deep sea area including the trench, I was able to almost measure seafloor topography of the whole world.
Our EM302 is bottom of a ship outfit finished to a large ship and realizes the investigation in the short term and it is highly precise and also realizes the efficient depth of the water data acquisition.
I cover sea area almost all except the trench
I can monitor a water column and a scan image, various information including the situation of the unrest in real time
System outline
I am composed of four transmission devices, two receiving device
I can record the side scan image at the same time, too
Data sample of Umiyama
