South West Approaches, eastern North Atlantic

Air pressure; Air temperature; Electrical conductivity of the water column; Wind strength and direction; Vertical velocity of the water column (currents); Horizontal velocity of the water column (currents); Temperature of the water column

Meteorological packages; bathythermographs; CTD; satellite positioning systems; current profilers; thermistor chains

The data were collected during a detailed oceanographic survey of an off-shelf, deep water region of the South West Approaches to investigate the spatial variability, to examine the internal wave climate and validate/interpret remotely sensed images of the region. Thermistor chain, navigation, meteorology, sea surface temperature, XBT, shipborne ADCP and CTD data were collected as part of the experiment. Data were collected by the Applied Oceanography Section of the Sonar Performance Division at DRA, Portland. Thermistor chain, sea surface temperature and meteorology data are stored in the DRA archive system and have been processed to the DRA standard MIDAS user data file format. These data have been screened for format and data errors and corrected to produce a 'clean' data set. The XBT, CTD and navigation data are also stored in the division archive, but have not been screened and are not stored under the MIDAS system. The ADCP data have been converted to the MIDAS format but have not yet been screened.
