Narrative Documents

POL 250 KHz Acoustic Doppler Current Profiler

The ADCP sends out short acoustic pulses, typically lasting a few thousandths of a second, at a fixed frequency. The acoustic pulses are transmitted in two narrow beams at right angles to each other and 30 degrees to the vertical and are reflected back to the ADCP by small particles, such as plankton, which move with the water. The frequency of the reflected signal is changed by a small amount proportional to the current speed, the Doppler shift. By measuring the frequency change along the two beams the speed and direction of the currents are determined. The currents at different heights through the water are obtained by chopping the return signal into segments by time.

The 250 KHz ADCP has a range of 100m and can measure up to 24 bins. However the technique has some limitations which reduce the amount of good data return. The closest bins to the transducer can give erroneous data due to the time taken for transients to decay and the far end bins can be affected by interference from side lobes reflected from the sea surface. Hence the good data return bins are usually between 25% of the depth from the surface and 10% of depth from the bottom.

ADCP specification

  Range Accuracy
Speed 2 to 350 cm/s +/- 4 cm/s
Direction see ADCP angle correction below
Tilt Two tilts measured at 90 degrees to each other

ADCP frame angle correction

The compass, manufactured by Digicourse (no longer in production), measures the angle between magnetic north and the frame. The two beams can be converted into east and north components by using the angle obtained by the compass and trigonometry. During the North Sea Project the compass showed a tendency to return arbitrary zero directions thus giving directions of flow different from those predicted by tidal models and previous current meter records. Also the frame moved on the sea floor during some storm events. A correction was then required to the frame angle for each deployment.

The ADCP data were first processed through the software. The statistical analysis gave the angle of maximum variance, which was taken to represent the M2 major axis tidal ellipse angle. The compass, although giving incorrect readings of frame angle, was recording direction to an unknown fixed position. The frame angle was adjusted by adding a correction angle.

The correction angle was calculated from the difference between the M2 major axis tidal ellipse angle from a model and the angle of maximum variance calculated from the initial raw data analysis. The model gave a depth average value, so the angle of maximum variance obtained from the data bin closest to this depth was needed. The bin used was found by taking the bin nearest to a value z=0.4D, where D is the total depth of water and z is the height from the bottom (Prandle, 1982). There is an 180 degree ambiguity in the calculation of the angle of maximum variance which was resolved by study of the M2 tidal phase given by the model and by other observations.

North Sea Project Resuspension Experiments ADCP data processing

Data processing at POL, UK

The 250 KHz ADCP deployed during the Resuspension Experiments of the North Sea Project was configured as illustrated below. The ADCP angle correction was applied to the data (as described in the instrument description) and data from the top (near surface) bins were excluded where appropriate due to 'spikes' outweighing the signal or bins not being in the water.

Data processing at BODC

The data were converted from ASCII format into BODC QXF, a subset of NetCDF. The data where then visually inspected, for quality control purposes, using in house software.

General Data Screening carried out by BODC

BODC screen both the series header qualifying information and the parameter values in the data cycles themselves.

Header information is inspected for:

  • Irregularities such as unfeasible values
  • Inconsistencies between related information, for example:
    • Times for instrument deployment and for start/end of data series
    • Length of record and the number of data cycles/cycle interval
    • Parameters expected and the parameters actually present in the data cycles
  • Originator's comments on meter/mooring performance and data quality

Documents are written by BODC highlighting irregularities which cannot be resolved.

Data cycles are inspected using time or depth series plots of all parameters. Currents are additionally inspected using vector scatter plots and time series plots of North and East velocity components. These presentations undergo intrinsic and extrinsic screening to detect infeasible values within the data cycles themselves and inconsistencies as seen when comparing characteristics of adjacent data sets displaced with respect to depth, position or time. Values suspected of being of non-oceanographic origin may be tagged with the BODC flag denoting suspect value; the data values will not be altered.

The following types of irregularity, each relying on visual detection in the plot, are amongst those which may be flagged as suspect:

  • Spurious data at the start or end of the record.
  • Obvious spikes occurring in periods free from meteorological disturbance.
  • A sequence of constant values in consecutive data cycles.

If a large percentage of the data is affected by irregularities then a Problem Report will be written rather than flagging the individual suspect values. Problem Reports are also used to highlight irregularities seen in the graphical data presentations.

Inconsistencies between the characteristics of the data set and those of its neighbours are sought and, where necessary, documented. This covers inconsistencies such as the following:

  • Maximum and minimum values of parameters (spikes excluded).
  • The occurrence of meteorological events.

This intrinsic and extrinsic screening of the parameter values seeks to confirm the qualifying information and the source laboratory's comments on the series. In screening and collating information, every care is taken to ensure that errors of BODC making are not introduced.


Project Information

North Sea Project

The North Sea Project (NSP) was the first Marine Sciences Community Research project of the Natural Environment Research Council (NERC). It evolved from a NERC review of shelf sea research, which identified the need for a concerted multidisciplinary study of circulation, transport and production.

The ultimate aim of the NERC North Sea Project was the development of a suite of prognostic water quality models to aid management of the North Sea. To progress towards water quality models, three intermediate objectives were pursued in parallel:

  • Production of a 3-D transport model for any conservative passive constituent, incorporating improved representations of the necessary physics - hydrodynamics and dispersion;
  • Identifying and quantifying non-conservative processes - sources and sinks determining the cycling and fate of individual constituents;
  • Defining a complete seasonal cycle as a database for all the observational studies needed to formulate, drive and test models.

Proudman Oceanographic Laboratory hosted the project, which involved over 200 scientists and support staff from NERC and other Government funded laboratories, as well as seven universities and polytechnics.

The project ran from 1987 to 1992, with marine field data collection between April 1988 and October 1989. One shakedown (CH28) and fifteen survey cruises (Table 1), each lasting 12 days and following the same track, were repeated monthly. The track selected covered the summer-stratified waters of the north and the homogeneous waters in the Southern Bight in about equal lengths together with their separating frontal band from Flamborough head to Dogger Bank, the Friesian Islands and the German Bight. Mooring stations were maintained at six sites for the duration of the project.

Alternating with the survey cruises were process study cruises (Table 2), which investigated some particular aspect of the science of the North Sea. These included fronts (nearshore, circulation and mixing), sandwaves and sandbanks, plumes (Humber, Wash, Thames and Rhine), resuspension, air-sea exchange, primary productivity and blooms/chemistry.

In addition to the main data collection period, a series of cruises took place between October 1989 and October 1990 that followed up work done on previous cruises (Table 3). Process studies relating to blooms, plumes (Humber, Wash and Rhine), sandwaves and the flux of contaminants through the Dover Strait were carried out as well as two `survey' cruises.

The data collected during the observational phase of the North Sea Project comprised one of the most detailed sets of observations ever undertaken in any shallow shelf sea at that time.


North Sea Project Resuspension Process Study

The ratio of particulate to dissolved material which is so important to water quality is affected by resuspension which, in turn, depends on the character of the sea bed, biological influences, tidal currents, wind, wave and seasonal stratification. The objectives of the three resuspension cruises were to make time series observations of physical, sedimentological and biological properties of the sediment, suspended particle material and water at two sites in the North Sea, using a variety of moored instruments, CTD/water bottle casts, pumped sampling and sediment grabs and box cores.

The two sites were:

    • Northern Site
    • 54° 35'N, 004° 50'E
    • 45m depth
    • muddy sand
    • seasonally stratified water column
    • Southern Site
    • 52° 40'N, 003° 40'E
    • 27m depth
    • sand
    • permanently well-mixed water column
