The SBP shares the receive transducer array of the EM122 echo sounder and can be operated in conjunction with the EM122 or EM710 multibeam systems. It uses narrow Tx & Rx beams (3° x 3°) and operates in a frequency range of 2.5 to 7kHz . This system is permanently mounted on the ships gondola and will be operated continuously regardless of science objectives unless specifically advised otherwise, or causing interference.
The SBP120 is utilised to image sedimentary layers beneath the seabed with a max vertical resolution of 0.3 ms and penetration of up to 100 m in loose unconsolidated sediment (or ~25 m in sand).
