We investigate experimentally the properties of spatio-temporal intermittency states (turbulent bursts and spiral turbulence) in the counter-rotating Couette-Taylor system. The mean turbulent fraction increases continuously from turbulent bursts to spiral turbulence and depends on the angular velocity of both cylinders. The axial velocity of turbulent spirals, which depends only on the outer cylinder, is smaller than the azimuthal component.
