Cruise Inventory Information

| Short name | CH56 |
| Objectives and Narrative |
The broad aim as set out in the cruise plan was to study the circulation in the Flamborough frontal region of the North Sea. This formed a process study as part of the NERC North Sea project (1988-89).
The methods were: 1. To survey the frontal region and provide salinity, temperature and current sections by using the ship-mounted acoustic doppler current profiler (ADCP) together with the sea-soar towed vehicle. Some of these sections were to be repeated over a tidal cycle so that tidal currents could be removed from the data and interactions with the tide could be studied. For salinity and temperature, the CTD was to be available as well as the sea-soar, while continuous surface sampling was to run throughout the cruise. 2. To deploy moorings at the sites. These consisted of a current meter string at FA, a current meter string and thermistor chain at FB, an ADCP and thermistor chain at DB. A current meter string for DB was also prepared. Moorings were to be recovered during Challenger cruise 58/89. 3. To deploy and later recover 10 drifting buoys, Argos tracked and Decca position recording, in two groups of 5 spanning the front. 5 of the buoys were to be redeployed for recovery during cruise 58. 4. Photographs of the (standby) radar screen were to be taken for a study of the technique of wave measurement by radar. All the planned programme work was successfully carried out, except that problems with drifting buoys meant that a proposed redeployment did not take place. |
