Page 40: Checking Transceiver And Transducer Settings
Context If you are using a EK80 that has been in use for some time, you can safely assume that the transceivers and transducers have been set up properly. However, the procedure may prove useful if you are an inexperienced user. Make sure that you do not change any important settings.
Page 41 This is the installation depth of the transducer; the vertical location of the transducer face relative to the water surface. In order to measure correct water depth, the EK80 needs to know the vertical distance between the vessel's water line and the acoustic face of each transducer.
Page 42: Selecting Normal Mode To Start Pinging
The EK80 system is now transmitting acoustic pulses ("pinging") into the water. Further requirements When the EK80 system starts, it is very important that it detects the bottom correctly. In most cases this will take place automatically. However, we have experienced that large...
Page 43: Switching Between Adcp And Echo Sounder Operation
In these cases the sounder may display the bottom at 0.0 metres at the top of the fish school. In order to aid the EK80 system to locate the correct depth, you must adjust to bottom maximum and minimum ranges according to the actual bottom depth.
Page 44: Verifying That The Bottom Is Correctly Detected
Transceiver page, page 791 Verifying that the bottom is correctly detected Locating the bottom (seafloor) is important for the EK80 system. The EK80 system needs this bottom lock to locate the correct depth, and to stay on this depth during operation, even if the depth changes continuously.
Page 45: Checking And/Or Editing The Transceiver Parameters
Result If the EK80 system should lose bottom detection due to air in the water or other disturbances, it will try to relocate the depth within the minimum and maximum depths you have defined.
Page 46: Turning Off The Ek80 System
Exit Context When you do not use the EK80 system, turn it off. If you are not using the EK80 system for a long period of time, turn off the transceiver.Use the on/off switch on the power supply, or disengage the circuit breakers.
Page 47 The Wide Band Transceiver (WBT) is not fitted with an on/off switch. You can leave the unit permanently turned on. If you are not using the EK80 system for a long period of time, turn off or disconnect the power supply.

User interface Surface echogram description A Surface echogram is mainly used when you wish to look at the entire water column starting from the sea surface and down to the sea bottom. Since this echogram is referenced to the sea surface, the sea bottom contour will vary with the actual depth. You can select the start range (the depth from which the echogram starts) and the vertical range (the vertical "length"...
Page 469 Kongsberg EK80 Reference Manual This is the start depth of the echogram In a Surface echogram you may wish to start the echogram from the surface, and will then set the to 0 (zero). You will then see the transmit Start Range pulse as a strong echo at the top of the echogram.
Page 470: Bottom Echogram Description
User interface The labels can be changed on the page in the dialog box. Horizontal Axis Echogram This is the lower end of the chosen depth range This depth is normally a few meters below the bottom contour, depending on the chosen range.
Page 471 Kongsberg EK80 Reference Manual Note The echogram is only drawn for pings that have a successful bottom detection. Since the Bottom echogram is referenced to the bottom, the value must be Start Range negative. If you wish to start your echogram from 10 meters above the bottom, you must set the to –10 m.
Page 472 User interface Transducer identification This text identifies the transducer - and thus also the channel - used to create the echogram. In this context, the term channel is used as a common term to identify the combination of transceiver, transducer and operating frequency. This is the scope view The Scope view is used to indicate how strong each echo is.
Page 473: Pelagic Echogram Description
Pelagic echograms are useful when you work in deeper waters. The reduced range and the fact that you do not need to wait for the bottom echo means that the ping rate is increased. The software algorithms in the EK80 system are designed to work without the bottom detection reference.
Page 474 User interface This is the start depth of the echogram In a Pelagic echogram you may wish to start the echogram from a certain distance below the surface, and will then set the to a relatively large Start Range numerical value. Echoes These are echoes from fish or other objects in the water column.
Page 475: Trawl Echogram Description
Trawl sensor systems (such as Kongsberg PI, PX and ITI) communicate headrope depth, and/or the distance from the headrope to the footrope (trawl opening), to the EK80 system at regular intervals. The information can be used to draw the upper and/or lower trawl lines in the echogram.
Page 476 User interface Note The Trawl echogram is only drawn when trawl position information is available. The distance from the headrope to the footrope (trawl opening) can be manually set on the page. This is useful for trawl sensor systems that do not measure the trawl opening, or Trawl when the measured distance is unreliable.
Page 477 Trawl sensor systems (such as Kongsberg PI, PX and ITI) communicate headrope depth, and/or the distance from the headrope to the footrope (trawl opening), to the EK80 system at regular intervals. The information can be used to draw the upper and/or lower trawl lines in the echogram.
Page 478 User interface This is the bottom (seabed) The bottom is shown with a strong contour. Since the echogram is referenced to the sea surface, the bottom will vary with the actual depth. Different bottom conditions will have a visual effect on how the bottom echo is drawn. A hard bottom (rock) will give you a stronger echo - and thus a darker colour - than a soft bottom (mud or silt).
Page 479: Velocity Measurement (Adcp) Views
The bottom bar provides specific tabs to open selected views. When fitted with hardware for velocity measurements, the EK80 can be used in both normal echo sounder mode and in ADCP mode. The bottom bar provides separate tabs for velocity measurement (ADCP) and echogram views.

The circular cross-section is split into several slices. To successfully calibrate the EK80 system you need to place a number of target detections in each slice. The echoes must be distributed within the entire beam cross-section. In order to do this, the target sphere must be physically moved inside the beam during the calibration process.
Page 581 The number of sphere detections should be approximately the same for each slice, and in total not more than 100 for the whole beam cross-section. Any adjustments to the EK80 system files are done automatically. No gain adjustments are required.

Page 594: Ping Average Function
Functions and dialog boxes Ping Average function The acoustic Doppler current profiler (ADCP) works by transmitting constant frequency pings into the water. The velocity of the water current is calculated by measuring the time it takes for the echoes to be returned and the changes in the frequency caused by the Doppler effect.
Page 595: Tvg (Time Variable Gain) Functiontvg (Time Variable Gain) Function
Active The EK80 transmits high energy sound wave pulses into the sea. A flat bottom reflects the transmitted wave as if it was a mirror. The propagating energy is spread over a larger and larger area as it travels down to the bottom and up again. The energy is spread over a four times larger area every time the travel distance doubles.
Page 596 Functions and dialog boxes When a sound pulse is travelling from the transducer through the water it will undergo geometrical spreading. A large school of fish reflects sound waves similarly. This type of spreading is referred to as square-law or 20 log TVG (Time Variable Gain) spreading. When a school of fish covers the whole acoustic beam cross section, the received echo will increase with range simply because the acoustic beam cross section increases with range.

In fresh water we suggest that you set the sound speed value to 1450 m/s. Water Column page To achieve correct echo information, the current environmental parameters must be known to the EK80 system. The page collects these parameters. These must be Water Column defined to match the current conditions.
Page 666 Sound travels at different speeds in salt and fresh water. For this reason, the EK80 system must know your water profile. The default setting is Salt. Freshwater/saltwater settings, temperature, salinity, acidity, depth, and the operating frequency for each transducer are all used to calculate absorption. The absorption value is, in turn, used for each sample.
Page 667 Kongsberg EK80 Reference Manual Acidity The equations used by the EK80 system to calculate the absorption requires a value for acidity. Unless you have any specific reasons to apply a specific value, use the default value of 8 pH. Depth The equations used by the EK80 system to calculate the absorption and the sound speed requires a value for depth.

Page 837: Vessel Coordinate System
Kongsberg EK80 Reference Manual Vessel coordinate system The vessel coordinate system is established to define the relative physical locations of system units and sensors. When you have several different sensors and transducers on your vessel, and you wish each of them to provide accurate data, you need to know their relative physical positions. The antenna of a position sensor is typically mounted high above the superstructure, while a motion sensor is located close to the vessel’s centre of gravity.
Page 838 Concept descriptions antennas, echo sounder and sonar transducers, motion reference units, etc.) are referenced to the origin. In most cases, the location of the vessel’s "official" origin has been defined by the designer or shipyard. This origin is normally identified with a physical marking, and also shown on the vessel drawings.

Page 841: Sound Speed Algorithms
Salt water algorithm The sound speed calculations made by the EK80 for salt water are based on the international standard algorithm, often known as the UNESCO algorithm. This algorithm uses pressure rather than depth, and the EK80 thus provides a conversion from the depth value provided to pressure.

0.00 to indicate that no reliable detection was obtained. The EK80 algorithm is designed to handle a number of difficult situations. The algorithm maintains bottom lock for a discontinuous jump in bottom depth. It avoids false bottom detections on for example a dense school of fish.
Page 846: About Sound Wave Propagation
1430 m/s. Unless you have a relevant sensor available, a good average sound speed value is 1470 m/s. The EK80 transmits high energy sound wave pulses into the sea. A flat bottom reflects the transmitted wave as if it was a mirror. The propagating energy is spread over a larger and larger area as it travels down to the bottom and up again.
Page 847: What Is Sampling
10 dB/km in sea water. At 200 kHz the absorption is 10 dB/km in fresh water and 50 dB/km in salt water. The EK80 must know which water type is present in order to compensate for these losses correctly.
Page 848 Concept descriptions In this coordinate system, the Y-axis is voltage (or “volume”) and the X-axis is time. This is a continuous flow of data, an analogue signal, for example an echo. This line identifies the samples that the system is extracting from the analogue signal. Each sample is identified with the time it was taken.
Page 849: Acoustic Noise
Kongsberg EK80 Reference Manual Acoustic noise As with any other hydroacoustic systems, the quality of the EK80 echo data and presentations are subject to unwanted acoustic noise. The echoes from any large and small target must be detected inside the noise.
Page 850 Concept descriptions A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise. While SNR is commonly quoted for electrical signals, it can be applied to any form of signal [...]. Wikipedia, Copied September 2013 The signal is the echo that we want to know something about, while the noise is any unwanted signals or disturbances.
Page 851: Self Noise
Kongsberg EK80 Reference Manual noise created by their own electronic circuitry. Digital noise created by the converter and processing circuitry can also create noise problems. The converters transform the analogue echoes to digital format. Signal processing circuitry can create digital noise.
Page 852 Concept descriptions Propeller cavitation is a severe source of noise. "Singing" propellers might be a source of noise, which interferes at discrete frequencies. In some cases static discharge from the rotating propeller shaft may be quite disturbing. Cavitation Cavitation is the formation of small air bubbles close to the transducer face.
Page 853 Kongsberg EK80 Reference Manual Turbulent flow Laminar flow Air bubbles Air bubbles absorb and reflect the sound energy, and they may in worst cases block the sound transmission altogether. The boundary layer increases in thickness when it becomes turbulent. The boundary layer is thin in the forward part of the vessel hull, and increases as it moves aft.

The Doppler effect (or the Doppler shift) is the change in frequency of a wave in relation to an observer who is moving relative to the wave source.
Page 857 Kongsberg EK80 Reference Manual The array transducer for ADCP uses four beams. The angle between the centre line of each beam and the vertical line from the transducer is approximately 30 degrees. - Velocity estimates at each depth are found by using the echoes from one Depth Cell depth cell.

The Doppler effect (or the Doppler shift) is the change in frequency of a wave in relation to an observer who is moving relative to the wave source.
Page 859: Depth Cells
This "sliding cell method" offers smoother velocity results in the ADCP views. By processing the echo data from the entire beam, the EK80 is able to present an accurate velocity profile of the column covered by the beam.
Page 860: Current Velocity
Concept descriptions Current velocity Water current velocity is measured in each of the beams of the ADCP transducer. Through processing the velocities relative to the vessel (Vessel Velocity) and to earth coordinates (Geographical) are calculated. The effect of the vessel speed is removed from the measured velocities.
Page 861: Adcp Data
Kongsberg EK80 Reference Manual Illustration: Each measurement of the water current velocity is presented as a vector drawn as an arrow. The length of the arrow indicates the velocity of the water. The tip of the arrow indicates the direction. The current velocity can be broken down into components in three dimensions.
Page 862 Concept descriptions Using data from GPS and motion sensors, vessel velocity values are recalculated into global coordinate oriented values and the velocity of the vessel is removed. The result is the global current velocity values, velocites in north-south and east-west direction. Velocity data Velocity data are output in units of m/s or knots.
Page 863: Ping Average Using Sliding Average
Kongsberg EK80 Reference Manual Percent good data The term percent good is commonly used to describe the total remaining value of an asset after a certain time compared to the value of the original asset. The percent good fraction is calculated using the number of pings selected with the function.
