Description | |
Summary | The data were collected as part of a DRA experiment to explore the remote sensing capabilities of the SIR-B synthetic-aperture radar (SAR) equipment fitted to the NASA space shuttle Challenger. Thermistor chain measurements were made of internal wave and mesoscale activity in the upper 200m. In addition to the thermistor chain data, navigation, meteorological (paper records), XBT (mostly paper records), CTD, towed sonar (paper records) and expendable current profiler (XCP) data were gathered. Data were collected by the Applied Oceanography Section of the Sonar Performance Division at DRA, Portland. Thermistor chain and navigation 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 XCP data have also been screened and corrected, but are not stored under the MIDAS system. |
