Nortek Aquadopp Open Water Current Meter
This instrument provides 3D acoustic doppler current measurements along with standard measurements of temperature, pressure, tilt and direction. It can be used in real time measurement situations or can log to an internal recorder powered by internal batteries. It can also be configured to measure surface wave height, period and direction concurrently. It has the unique feature of being run in 'diagnostic' mode when set to collect data at 1 Hz frequency in user specified intervals. This allows studies of mooring motion and the performance of other current meters to be conducted. It can be set in various configurations with titanium housings for deployment at greater depths.
Standard Measured Parameters
- 3D current velocity (East/North/Up, X/Y/Z or Beam 1/2/3)
- Acoustic signal strength (Beam 1/2/3)
- Compass
- Tilt
- Temperature
- Pressure
- Battery voltage
- Status code
- Error code
Surface wave monitoring
The standard Aquadopp is suitable for measuring surface wave height, period, and direction, which are calculated using the PUV method whereby spectra are estimated based on a combination of the pressure signal recorded by the instrument (P) and two horizontal components of the wave orbital velocity (U and V). More specifically, the pressure signal is used to provide an estimate of the wave frequency spectrum. The energy in this spectrum is then used to estimate wave height and period. The measurements of the wave orbital velocities are used to provide an estimate of the wave direction. Since these estimates are based on the distribution of wave energy and are not direct measurements of the free surface, they should be considered inferred estimates.
Both the dynamic pressure and the orbital velocities are driven by surface waves. The signals that are associated with these properties are complicated by the fact that they attenuate (that is the signals are weaker) with depth. The exact behaviour of the attenuation is determined by the water depth and the wavelength being observed. The greater the water depth the greater the attenuation; likewise, the shorter the wavelength (or higher the frequency of the wave) the greater the attenuation for a given water depth. This means that the estimation of wave parameters is limited by both water depth and wave frequency.

BODC Processing
Data processing
The data arrived at BODC as individual .mat files containing data collected on moorings OP1, OP2, OP3, OP4, OP5, OP6, OP7, CI1 and CI2. They were submitted as part of an accession which includes data from several mooring instruments e.g. ADCP, Aquadopp, RCM8, RCM11, RBR, SBE37 and SBE39.
Reformatting
The parameters from the originator's files were reformatted to internal format using BODC standard procedures.
The following parameters from the Aquadopp data were not reformatted as they are considered metadata or are not environmental variables: date, depth (m), botdepth (m), lat/lon, mooringname, nomdepth (m), serial_no, type, temp_offset_applied and press_offset_applied.
The table below includes the final variables and how they were mapped to the appropriate BODC parameter codes:

tilt | deg | ZNTHSS01 | deg | Tilt was not included in the data for 2017-2019 mooring deployments |
Battery voltage and amplitude channels were reformatted to help with the screening process and are not included in the final file but are avaiable upon request.
None of the parameters required a unit conversion and no derived parameters were created during reformatting.
Screening
The reformatted data were visualised using in house software and spikes or improbable values were flagged accordingly.
Originator's Data Processing
Sampling Strategy
Sampling was carried out as part of the BAS LTMS (British Antarctic Survey Long Term Monitoring and Survey) until 2016. From 2016 onwards the moorings are split between 'The Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports (ORCHESTRA)' project and 'Dynamics of the Orkney Passage Outflow (DynOPO)' project.
The projects involve the deployment of moorings CI1, CI2, OP1, OP2, OP3, OP4, OP5, OP6 and OP7 in the Southern Ocean, situated north of Coronation Island and the Orkney Passage in the Weddell and Scotia Sea.
Moorings CI1 and CI2 were deployed from 2005 to 2007 and moorings OP1, OP2, OP3, OP4, OP5 and OP6 have been continuously maintained since 2007 with the addition of OP7 in 2015.
Aquadopp Deep Water current meters data have been collected at 15 minute intervals since 2011. Gaps in the series may be related to either instruments not being recovered, or data not being collected due to instrument malfunction.
Data Processing
Little information is known with regards to the exact details of the calibrations carried out on the mooring data. Originator's data processing, visualisation and calibration were done through the use of Matlab scripts written for Matlab R2014b version.
The originator did not apply corrections to current velocity, direction or components for magnetic variation for the data from 2011 to 2013 as the variation in this region is less than one degree.
According to the originator, it has been found that in some conditions Aquadopp current meters overread current speeds compared with a mechanical vector measuring current meter and there is considerable uncertainty associated with the exact corrections that should be applied. Because of the continuing uncertainties of how best to correct for the differing characteristics of these instruments, no correction has been applied to these data.
Offsets applied to the data were:
