type: Multibeam Echosounder
description: The EM 710 multibeam echosounder is a high to very high resolution (up to 800 soundings per ping) seabed mapping system capable of meeting all relevant survey standards. The system configuration can be tailored to the user's requirement, allowing for choice of beam widths as well as transmission modes. The minimum survey depth is from less than 3 meters below the transducers, and the maximum depth is approximately 2000 meters, somewhat dependant upon array size. Across track coverage (maximum swath width 140º) is up to 5.5 times water depth, to a maximum survey depth more than 2000 meters. The along track beamwidth depends upon the chosen transmit transducer configuration with 0.5º, 1º and 2º available as standard. The receive beam width is either 1º or 2º depending on the chosen receive transducer. The EM 710 operates at sonar frequencies in the 70 to 100 kHz range. The transmit fan is divided into three sectors to maximize range capability, but also to suppress interference from multiples of strong bottom echoes. The sectors are transmitted sequentially within each ping, and uses distinct frequencies or waveforms.

description: The R/V Sikuliaq, pronounced [see-KOO-lee-auk], is a 261-foot oceanographic research ship capable of bringing scientists to the ice- choked waters of Alaska and the polar regions. The Sikuliaq, one of the most advanced university research vessels in the world, is able to break ice up to 2.5 feet thick. Constructed at Marinette Marine Corporation, a shipyard in Marinette, Wisconsin, the Sikuliaq is home ported in Alaska, at UAF's Seward Marine Center in Seward Alaska. The vessel is owned by the National Science Foundation and operated by the School of Fisheries and Ocean Sciences at the University of Alaska Fairbanks, as part of the U.S. academic research fleet. It is used by scientists in the U.S. and international oceanographic community through the University-National Oceanographic Laboratory System.

type: Multibeam Echosounder
description: 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.
