MOORING
Until 1998, the YOYO mooring was a subsurface
mooring, that is to say it was totally under the
surface mooring. It was a subsurface float which
was load to maintain the mooring in a vertical
position. A surface buoy was load to transmit
measures to an Argos satellite thanks to an
acoustic link.
In order to go to the surface, the mooring has
to be modified. It is a two legged mooring with
intermediate subsurface flotation. The cable
between the surface buoy and intermediate
subsurface flotation is elastic. The other part
is profiling on a taut cable only attached to the
buoy it is a pendular cable.
In case of bad weather, the YOYO is not stuck
near the surface.
The description of the surface buoy was more
particularly developed in an other sheet.
