Cruise ReportUoB Cruise No.GS-10-162/IMR No. 2010101University of Bergen (UoB)2. METHODS2.1. Research vesselR/V G.O.SARS has a length of 77.4 m, beam of 16.4 m and a displacement of 4067 tonnes, andis owned by the Institute of Marine Research and the University of Bergen. R/V G.O.SARS isoutfitted with diesel-electric propulsion plant and 2 Teco Westinghouse DC motors and has atop speed of 17.5 knots. Its engines are noise reduced; lowering the noise emission under waterby 99% compared to conventional research vessels. The main duties are research operationswithin the areas of fishery, acoustic, environment and geology.To accommodate these tasks the vessel is arranged with two sheltered hangars midships forenvironmental and geological research operations. These hangars have 6 winches all with 6000m cable length (either with electrical or optical cording) for lowering scientific equipment tothe deepest parts of the Norwegian Sea. The vessels heavy duty cranes and handling equipmentare located in the main mid-ship hangar and on the aft deck. These include 6 cranes for liftingequipment from 2 tonnes up to 16 tonnes, and one CTD davit crane with a capacity of 2 tonnes.One Z-frame crane, with a capacity of 8 tonnes, is located on the stern. The operation centre isarranged on the 5th deck, controlling all acoustic and hydrographical equipment. Furthermore,the vessel is arranged with 15 specialised laboratories. A number of sensitive transducers arelocated in two independent drop keels.The acoustic equipment on R/V G.O.SARS is state of the art, consisting of the following: An echo sounder (EK 60) that can operate on 6 different frequencies simultaneously (18,38, 70, 120, 200, 400 kHz).2 multibeam echo sounders, EM300 with a 30 kHz transducer and EM1002 with a 95 kHztransducerKongsberg TOPAS PS18 sonarSimrad HIPAP acoustic positioning system2 R.D.I. ADCP, acoustic doppler current profiler, 75 and 150 kHzThe TOPAS and EM300 systems are hull mounted, while the other acoustic transducers areplaced in retractable drop keels, lowering the transducers below the air bubble layer close to thehull, which decreases noise and enables data acquisition up to wind speeds of 9 Beaufort. Thedrop keel also improves the stability of the ship.2

Cruise ReportUoB Cruise No.GS-10-162/IMR No. 2010101University of Bergen (UoB)R/V G.O.SARS has room for 45 persons in 19 single berth cabins and 13 double berth cabinsand it has a crew of 15. We thank the captain Preben Vindenes and the crew on R/V G.O.SARSfor their help during the cruise.2.2. NavigationThe shipboard navigation system is a Simrad Kongsberg system. The GPS part is a dualantenna system for heading and position determination. This system is able to create positionaccuracy of 2m 2o (Differential GPS signal via satellite). No post-processing was carried out.The logged navigation has datum WGS84. ASCII files including positional fixes for every 10sec survey time provided in a geographic co-ordinates (lat. and long.) format were madeavailable for later plotting purposes (see the track on the attached Figures).2.3. Sound Velocity SourcesThe 911plus CTD system was used at all stations for creating velocity profile. The systemincludes: SBE 9plus Underwater Unit with sensors for C (conductivity), T (temperature), P(pressure) and O (oxygen) and a submersible pump. SBE 11plus Deck Unit Computer for display logging and read time date acquisition.2.3.1. SBE 9plus Underwater UnitStandard underwater units have aluminium housings rated to 6800 meters, and are suppliedwith one conductivity and one temperature sensor (fitted with a TC Duct and constant-flowpump), and an internally mounted, temperature-compensated Paroscientific Digiquartz pressuresensor for 6800 meter (10,000 psia) full scale range.2.3.2. SBE 11plus Deck UnitSBE 11plus Deck Units include RS-232 and IEEE-488 computer interfaces, NMEA 0183interface for adding GPS position to CTD data, 12-bit A/D input channel for surface PARsensor, switch-selectable 115/230 VAC operation, audio tape interface (data backup), LEDreadout for raw data, and audible bottom contact (or altimeter) alarm. Calibration coefficientsare stored in EEPROM, and a separate microcontroller converts raw CTD data to temperature,3

Cruise ReportUoB Cruise No.GS-10-162/IMR No. 2010101University of Bergen (UoB)depth, salinity, etc. The SBE 11plus is prewired for installation of the optional sub-carriermodem (including water sampler control push buttons and status lights).2.3.3. Standard CTD CarouselThe heart of the Carousel is the magnetically-actuated lanyard release. A pressure-proofelectromagnet at each bottle position is energized on command to release the latch holding thebottle lanyard. The standard Carousel includes the electronics/release assembly (12- position),mounting hub, adapter plates, protective frame, and CTD extension stand with a 9plus CTDunderwater unit.2.3.4. SEA-BIRD Software SEASAVE - real-time data acquisition and simultaneous keyboard control of bottle firing. Atypical real-time CTD data plot shows how the software automatically marks the display withbottle numbers, keeps track of which bottles have been fired, and creates a bottle data fileduring real-time data collection. SBE Data Processing - filtering, aligning, averaging, and display of CTD and auxiliary sensordata and derived variables.2.4. Simrad Multibeam echosounderThe Kongsberg Simrad Multibeam echo sounders EM300 and EM1002 are designed for seabedmapping at variable depths, and therefore have variable resolution capacities. The echosounders consist of three units:a) Transducer arraysb) Transceiver unitc) Operator stationTransducer arraysThe transducer arrays are different in form for the different models, but are used for bothtransmitting and receiving pulses. Both arrays are positioned on the front of the drop keel.Transceiver unitThe transceiver unit is a wall mounted cabinet with integrated shock and vibration absorbers. Itcontains transmission and reception electronics, the processors for beam formation, bottomdetection and control of all parameters with respect to gain, ping rate and transmission angles.4

Cruise ReportUoB Cruise No.GS-10-162/IMR No. 2010101University of Bergen (UoB)Operator stationThe operator station contains processors for beam-formation, bottom detection and parametercontrol as well as the operator interface.It detects: depth and sounding positionsraw ranges and beam pointing anglesseabed imagingvessel position and attitudesound speed datasystem installation and set-up parametersThe system does not require operator intervention during normal operation, but tracks thebottom automatically while adjusting mode, gain and range dependant parameters as required.To improve bottom detection, leading to an improved data quality, the system is interfaced withthe high frequency sonar.Data ProcessingThere are two software packages that are commonly used during the processing process: The Neptune software, which is used for post-processing of bathymetric data (i.e.cleaning and filtering of raw data etc.). The 3D-Fledermaus software is used for digital terrain modeling and plot generation.These terrain models can easily produce contour maps, 3D plots, combined bathymetryand acoustic imagery, depth profiles along specified routes, volume calculations etc.2.4.1. EM 300The Kongsberg Simrad EM 300 multibeam echo sounder is designed to do seabed mappingfrom 10 m depth to approximately 5000 m depth. Optimal data acquisition depths areconsidered to be below 300 m water depth. The system has a maximum ping rate of 10 Hz, with135 beams per ping. The beam widths are 1*2 , which gives a swath width in shallow water upto 5 times the water depth, or maximum swath widths of up to 5000 m. It has a nominal sonarfrequency of 30 kHz, which gives an optimal balance between small dimensions, narrow beamsand good range capability.Four different pulse lengths are used depending on the depth; 15 ms pulse length for depthslarger than 4000 m, 5 ms for deep water, 2 ms for intermediate depths and 0,7 ms for depths5

Cruise ReportUoB Cruise No.GS-10-162/IMR No. 2010101University of Bergen (UoB)shallower than 50 m. The different pulses give depth resolutions from 1 to 16 cm. There aretwo transducers on this model, one for transmitting and one for receiving pulses. Thetransmitter has 1 beamwidth and the receiver has 2 beam-width.2.5. TOPAS (Parametric Sub-bottom Profiler System)The TOPAS PS18 system is a single, narrow beam sub-bottom profiler system with electronicroll, pitch and heave stabilisation. The range resolution is normally less than 0.3 m, andpenetration capability is normally more than 150 m. The TOPAS profiler is designed around aparametric antenna utilizing the non-linear propagation characteristics of water to generate alow frequency acoustic pulse from a short, high frequency burst or from the inter-modulation oftwo high frequency signals. The received echoes are amplified, digitized, processed anddisplayed on-line, and printed out during the process. Raw, unprocessed data is stored for laterprocessing. There are several types of pulses that can be used, depending on the different depthand different use that is needed. Generally, high frequency gives high resolution, but lowpenetration, and for the Chirp pulse, maximum and minimum frequency is 6000 Hz and 1000Hz respectively. The Chirp (LFM) pulse was applied on the whole cruise due to shallow waterdepth. Ricker puls can also be used on shallow water depth, wich is set with constantfrequency, normally between 3000 and 4000 Hz.Chirp (LFM)Chirp waveforms are used for increasing the total transmitted energy thereby increasing thesignal-to-noise ratio and correspondingly the penetration. This wavelet is generated bytransmitting a burst consisting of two high frequencies swept in opposite directions.Sketch showing the Chirp waveform.6
