Deep-Arvor was designed by Ifremer to achieve more than 150 profiles from 4,000 meters depth, with CTD continuously pumping and oxygen measurements. After the validation of two first models at the sea, the industrialization has been entrusted to NKE. The first constructed prototypes of Deep-Arvor have been deployed successfully in May 2014. Thanks to its light weight, Deep-Arvor maintains the self-ballasting feature of Provor/Arvor and the easy deployment of Arvor. High resolution profiles are transmitted by the Iridium satellite system.
