  1. FOLLOW-ON OF A SUBSURFACE YOYO The YOYO-2001 project is to follow-on of a subsurface yoyo (Provost and du Chauffaut, 1996-1998) and benefits from the experience and skills gained in the course of development and testing of the latter. The YOYO is moved by a change of flotation due to pumping in and out hydraulic oil from an external bladder to an internal reservoir.This subsurface YOYO moves up and down along a taut cable of a subsurface mooring between a depth of 100 meters and a subsurface depth of about 50 meters. Subsurface YOYO’s q- are deployed at the equator and 20°W within the PIRATA mooring array (in the Atlantic) and at 41°S and 55°30’W within the Brazil Malvinas Confluence (South West Atlantic).
