| Status | Completed |
| Port of departure | Brest, France |

| Purpose | Research |
| Objectives | a) To complete a programme of measurements started in 1970, of tidal pressure and currents along the edge of the continental shelf bordering the British Seas by a chain of four stations between Little Sole Bank and Valentina
b) To continue an oceanoc circuit of tidal pressure measurements begun in 1974, by a line of stations along or near latitude 56.36N from about 50 miles west of Inishbofin to the 30W meridian c) To obtain data on tidal currents on and off the continental shelf near Porcupine Bank, to see if they show any relationship to the unusual diurnal tidal regime near St. Kilda and Rockall Bank d) To obtain a profile of currents at a site Z1 about 3100m deep, west of the Porcupine Bank shelf edge, to investigate the energy level of internal tides. |
