Shipboard acoustic doppler current profiler (ADCP) (MR08-02 - )
- Manufacturer : Teledyne-RDInstruments
- Type : Ocean Surveyor 75
By emitting acoustic pulse from ship bottom, the current speed and direction of down to 700m depth are measured by the doppler shift of reflected wave.

Shipboard acoustic doppler current profiler (ADCP) ( - MR08-E01)
- Manufacturer : RD Instruments
- Type : RD-10203075 vessel mount 75
By emitting acoustic pulse from ship bottom, the current speed and direction of down to 700m depth are measured by the doppler shift of reflected wave.

Conductivity temperature depth measurements (CTD)
- Manufacturer : Sea-Bird Electronics, Inc.
- Type : SBE 9 Plus,SBE 3,SBE 4 ,SBE 43 (, SBE 13)
CTD system measures the vertical profile of temperature, conductivity and pressure. On the R/V MIRAI, this system is operated with multicylinder water sampler. Observation signal is transmitted from sensor to the operation room on board using wire cable, and data collection is performed on real time, and electric power is supplied from vessel to sensor.

Expendable bathythermograph (XBT) (MR11-04 - )
- Manufacturer : Tsurumi Seiki Co., Ltd.
- Type : T-5,T-6,T-7,T-10, DeepBlue
XBT measures the vertical profile of water temperature during free fall of its probe part(temperature sensor) in the seawater. This system can be used at under way.
