Sensor or Sampling Distribution Fixed common depth - All sensors are grouped effectively at the same depth which is effectively fixed for the duration of the series
Sensor or Sampling Depth Datum Sea floor reference - Depth measured as a height above sea floor but converted into a depth relative to the sea surface according to the same datum as used for sea floor depth (applicable to instrument depths not bathymetric depths)
Sea Floor Depth Datum Instantaneous - Depth measured below water line or instantaneous water body surface

Definition of Rank

  • Rank 1 is a one-dimensional parameter
  • Rank 2 is a two-dimensional parameter
  • Rank 0 is a one-dimensional parameter describing the second dimension of a two-dimensional parameter (e.g. bin depths for moored ADCP data)

Data Access Policy

SIMORC data access conditions

The data collated and held at BODC on behalf of the SIMORC project are restricted. However, the data will be available to download from the Official SIMORC Website, as part of the project protocol. The data set will initially include data from the oil companies TOTAL, Shell and BP.


Narrative Documents

RPS Metocean CM04 acoustic current meter

An acoustic current meter for measuring horizontal current speed and direction, this instrument is specifically designed to measure solitons and other high frequency current phenomena. Recording intervals between 0.5 seconds and 10 minutes can be chosen. More information from the manufacturer can be found here

BODC Processing

Data were received by BODC in MS Excel spreadsheets. They were stabilised into a text format and then reformatted to QXF format using BODC transfer function 518. The following table shows how the variables within the files were mapped to the appropriate BODC parameter codes:

Original parameter name Original Units Description BODC Parameter Code BODC Units Comments
Time DD-MM-YYYY hh:mm:ss Date and time (Western Standard Time) AADYAA01 + AAFDZZ01 Day number and day fraction Converted to GMT by subtracting 8 hours.
CurSpd m/s Speed LCSAEL01 cm/sec *100
CurDirn degrees True Direction LCDAEL01 degrees True  
SeaWaterTemp degrees Celsius Sea temperature TEMPPR01 degrees Celsius  

Following transfer to QXF, the data were screened using BODC's in-house visualisation software, EDSERPLO.


Project Information

System of Industry Metocean data for the Offshore and Research Communities (SIMORC)

The EU-funded SIMORC project is a collaborative effort between MARIS (Netherlands), BODC (UK), the International Association of Oil and Gas Producers (OGP) and IOC-IODE to provide a harmonised and quality controlled metocean data set from data collected by oil and gas producers, accessible through the SIMORC protocol.
