Surpact: a wave-riderReverdin et al., Oceanography, april 2013

LOCEAN (Reverdin et al., 2013)Developed with SMRUTest Deployements in Fromvar/ Banyuls,Prototypes Pirata / PandoraFirst long deployments Strasse/SPURSTests for rain-rate (in progress)

Difficulty: C drifts quickly; other C-cell (cheaper, if possible)?

Measure C/T at 4cm depth; (and other parameters: SLP, wave spectra)

Atlantic ITCZ 7N-22W 6 July 2013
