Abstract

The importance of deep ocean observations in accurately understanding oceanic effects on anthropogenic climate changes has been gradually recognized. One suitable device for deep ocean observation is a profiling float, and a monitoring network consisting of many deep floats must be built by 2020. We are developing a deep float called Deep NINJA, which can submerge to a depth of 4,000 m. It has a height of 210 cm and a mass of 50 kg. Field tests of Deep NINJA have been carried out in coastal waters, and the first dive to 4,000 m depth is planned for summer 2012.
