Kongsberg/Simrad .raw files are generated by ME70, EK60 or ES60 instruments. They contain power and optionally angular position data with each beam/frequency identified by an independent channel. See the Simrad interface specification manual for further information. The .wcd files are generated by Kongsberg EM302 or EM122 instruments. See Kongsberg documentation for more information.

Kongsberg EM302
Multibeam Echosounder
The state of the art 30 kHz EM 302 deep water multibeam sonar is manufactured by Kongsberg, Inc of Norway. The EM 302 transducers are modular linear arrays in a
Mills cross configuration with separate units for transmit and receive. This sonar offers significantly larger swath width, increased data density and resolution. Beam
focusing is applied both during reception and transmission. The system has up to 288 beams / 432 soundings per swath with pointing angles automatically adjusted
according to achievable coverage or operator defined limits. In multi-ping mode, 2 swaths are generated per ping cycle, with up to 864 soundings. With multi-ping the
transmit fan is duplicated and transmitted with a small difference in along track tilt. The applied tilt takes into account depth, coverage and vessel speed to give a
constant sounding separation along track. The beam spacing can be adjusted as equi-distant or equi-angular. EM 302 uses both CW pulses and FM sweep pulses with
pulse compression on reception, in order to increase the maximum useful swath width. The transmit fan is split in several individual sectors with independent active
steering according to accomplish compensation for the vessel movements: yaw, pitch and roll. The high density, high resolution, large coverage and water column
capability makes EM 302 an ideal system to explore the sea bed and the water column for detection and characterization of a broad spectrum of features.

The R/V Thomas G. Thompson is owned by the Office of Naval Research (ONR) and operated under a Charter Party agreement by the School of Oceanography at the University of Washington as part of the UNOLS fleet (University National Oceanographic Laboratories System). The R/V Thomas G. Thompson (AGOR-23) was constructed by Halter Marine and was delivered to ONR on 8 July 1991. The Thompson is 274 ft in length, 52.5 ft. beam, and at full load has a 19 foot draft. The normal cruising speed is 11 knots, and offers a ships complement for 21 officers and crew, 2 marine technicians and berthing for up to 36 scientists.
