IFREMER has developed, through industrial partnership with NKE company, a free-drifting hydrographic profiler based on MARVOR technology and named PROVOR. As MARVOR, PROVOR is a self ballasted float. It has an important volume variation and can be used in a wide range of density gradient.
The lastest version, PROVOR CTS3, is now also a platform able to carry various sensors (dissolved oxygen, optical irradiance and transmittance).
ARVOR, which design has been performed by Ifremer, is a light and easy to deploy profiling float, fully Argo compatible.
