ObjectivesThe cruises were entirely devoted to an international exercise organised by SCOR/IAPSO/UNESCO working group no. 27 'tides of the open sea'. Most of the organisations in the world which use or have developed a pelagic sea bed pressure sensor were invited to compare their instruments in close proximity for a recording period of little more than a month. Since some were designed for oceanic depth and others for shelf depth, the testing area was chosen to be near a steep shelf edge, within easy reach of Brest.
