| Definition | A high-resolution multibeam echosounder designed to measure seafloor depth for use in mapping and inspection surveys. The EM 2040D is identical to the EM 2040, but features an additional receive transducer for dual-swath capability, enabling surveying to the surface or up to 10x the water depth. The EM 2040D is ideally suited for use on remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs) due to its 6000 m depth capability. The system consists of a transmit transducer, a receive transducer, a processing unit (PU) and an operator station (HWS). The EM 2040D transducers consist of separate linear arrays for transmit and receive in a Mills cross configuration. The transmit array is electronically steerable alongtrack while the receive array is steerable athwartship. Both arrays contain analog electronics and digital control units with Ethernet interfaces to the PU. The EM 2040 operates within a frequency range of 200-400 kHz and is depth-rated to 6000 m. Predicted system depth errors are in the order of 0.1 % of depth. This instrument has been superseded by the EM 2040D MK II, which offers a wider frequency bandwidth of 200-700 kHz. | ||
