Kongsberg Upgrades Its Multibeam Echosounder

on its EM 2040 MKII multibeam echosounder. The first enables the use of dual high frequencies to survey wide swaths of the seabed at much higher resolutions than before, while the second facilitates simultaneous collection of back scatter data using multiple frequencies.The EM 2040 MKII is a broadband multibeam echosounder system, which uses frequencies from 200kHz to 400kHz to yield a wide swath of up to 170 degrees. With the new high frequency feature, the EM 2040 MK II will additionally employ 600kHz and 700kHz frequencies to give enhanced detail over a swath of up to 120 degrees. This will

It aims to accelerate the scientific exploration and protection of the oceans.The maritime high-speed broadband service provided connectivity to relay broadcast images from Nekton’s submersible off the Seychelles last year. Along with Associated Press, Sky News and Sonardyne, it won the 2019 IBC Innovation Award for Content Distribution and the 2020 Royal Television Society News Technology Award.The

, or on the seafloor, it provides a measure of the water current. Alternatively, when mounted in a moving platform such as an undersea vehicle the instrument can measure motion relative to the water, or the seafloor. This is known as a Doppler velocity log (DVL). The first patents on the most capable broadband ADCPs were issued in 1997. This capability unleashed the modern era of current measurement. In the decades since, oceanographers and ocean engineers have employed these tools in a variety of configurations and thousands have been delivered. But what have the last few years brought to the field
