SeaGuardII DCP Wave
The SeaGuardII DCP Wave is a 600kHz Doppler Current Profiler
able to measure directional wave parameters and currents from
a bottom mounted installation.
The Acoustic Wave software 5759 used by the DCPS implements
unique features to improve the wave measurement accuracy by
optimizing the signal to noise ratio.
Maximum deployment depth is 40m in normal scatter
conditions.
Available as a self-recording instrument, it is easily
integrable into a real-time system offering reliable two-way
communication.
Redundant wave measurement for QA/QC can be implemented
by adding the wave and tide sensor 5218.
Applications:
• Navigation safety
• Prediction and modelling
• Energy assessment
• Infrastructure design
• Coastal processes, erosion
• Oil & Gas
Simple solution to measure waves, currents and water quality in
one instrument
• Independent measurement of waves and currents
• Field validated data-comparison with MOTUS buoy, Datawell
Waverider and pressure based non directional wave sensor
• Measures wave from centimeters to 20m
• 2Hz or 4Hz wave sampling
• Processing of up to three columns in parallel, provides flexible
setup with both surface referred and bottom referred cells.
Adaptive pulse technology automatically optimizes wave
measurement accuracy
The transmission pulse is automatically adapted to the current
sea conditions to provide best measurement achievable; a low
noise broadband mode is used for smaller waves, an extended
range broadband mode used for medium range waves and a
narrowband mode is applied for higher waves.
Expandable platform — Multiparameter monitoring
• Wide range of additional parameters available using
Aanderaa smart sensors; wave, tide, temperature,
conductivity, pressure, oxygen
• 4 analog inputs and 2 serial ports for integration of third
party sensors as for instance turbidity, pH, total algae, etc Smart Data quality control
• Automatic flagging of bad data; quality status for each cell
• Redundant wave energy spectrum and other wave
parameters when using the wave and tide sensor 5218
(provides time series)
• User selectable advanced autobeam algorithm; automatic
selection of the best 3-beams combination in case of
obstructions in one beam
Enhanced real-time functionality
• Serial port input for direct connection of modem with power
control
• Support AIS, GOES, pseudo binary formats
• Independent configuration of the recording and
transmission intervals
• Automatic retransmission of missing data
User friendly set up and data analysis
• Predeployment configuration software; RT Collector
• Modern post-processing software; Data Studio 3D
• Geoview web-based display for real-time application

scatters, expect a shorter range than for
waters with a high amount of scatters
