Data quality report

The temperature data are noisy throughout and should be treated with caution.

Data Access Policy

Public domain data

These data have no specific confidentiality restrictions for users. However, users must acknowledge data sources as it is not ethical to publish data without proper attribution. Any publication or other output resulting from usage of the data should include an acknowledgment.

The recommended acknowledgment is

"This study uses data from the data source/organisation/programme, provided by the British Oceanographic Data Centre and funded by the funding body."

Narrative Documents

Aanderaa SEAGUARD Recording Current Meter

A multi-frequency Doppler current sensor for measuring horizontal current speed and direction. The shallow water (SW), intermediate water (IW) and deep water (DW) models can be deployed to 300 m, 2000 m and 6000 m, respectively. The instrument has a maximum sampling rate of 0.5 Hz, a velocity range of 0 - 300 cm/s, and incorporates an electronic compass and a tilt sensor. A number of additional oceanographic sensors may also be attached.

Further details can be found in the manufacturer's specification sheet.

BODC Processing

Data were received in ASCII format files. The series were reformatted to QXF (a netCDF format) using the BODC transfer function 325. The following table shows how the variables within the file were mapped to the appropriate BODC parameter codes.

Following transfer to QXF, the data were screened using BODC's in-house visualisation software, EDSERPLO. Any data considered as suspect were flagged accordingly. Flags from the originator marking suspect data were retained during transfer.

Originator's Data Processing

Marine Scotland applied the standard manufacturers' calibrations to all current, temperature and salinity data and produced ASCII files for submission to BODC. Data files (.hmo) were named according to the mooring code and the instrument number. Each current meter file contained eastward and northward velocities and temperature. In cases where the temperature data ran for longer than the current data, the temperature records were saved as separate files appended 't'. Salinity data for each instrument were contained in files appended 's'. Header metadata were collated in additional files (.frm). Speed/Direction distributions (.csd) and harmonic analyses files (.lpr) for the current meter data were also generated.

Data Activity

FRS current meter mooring (771) from East Shetland 1

A current meter mooring was deployed by Marine Scotland, Aberdeen Marine Laboratory at East Shetland 1 (60° 18.67'N, 00° 41.79'W) on 24/05/2009 during the FRV Scotia cruise 0709S. The mooring was recovered on 05/10/2009 by the FRV Scotia cruise 1309S. The station had a nominal water depth of 94m.

The mooring consisted of the following instruments
