Arvor-Cm foat. We are very grateful to Michel Répécaud,
Louis Marié, Romaric Verney, David Le Berre, Matthias Jac-
quet and Aurélien Gangloff at Ifremer for the deployment of
the Arvor-C and Arvor-Cm profling foats during their cam-
paigns at sea.

One Arvor-Cm was successfully deployed for a short-
term experiment in the Bay of Vilaine in 2014, and three
Arvor-Cm foats were deployed in the Gulf of Lion and the
Bay of Biscay in 2015, for a total of about 400 cycles as of
February 2016. These experiments proved the value of the
data acquired, and the simplicity of use. The cage that pro-
tects the sensors and facilitates the recovery of the foat was
also highly appreciated.
Moreover, one Arvor-Cm was ftted with two different
chlorophyll sensors and two different turbidity sensors. For
each type of sensor, we will compare the acquired data to
assess the quality of their measurements at sea in 2016.
