Instruments

The Yamazaki-Nagai Laboratory of Ocean Ecosystem Dynamics uses a wide variety of instruments and equipment to conduct observations and collect data.

TurboMAP

TurboMAPTurboMAP1 on the deck of the Seiyo-maru.

TurboMAP, the Turbulence Ocean Microstructure Acquisition Profiler, was developed through a partnership among the University of Victoria, the Laboratory of Ocean Ecosystem Dynamics at the Tokyo University of Marine Science and Technology, and Alec Electronics (currently JFE Advantec).

The original TurboMAP is a free-fall profiler that measures biophysical microstructure.

TurboMAP-L is equipped with a laser fluorescence-based sensor in addition to the same sensors that are equipped to the original TurboMAP, such as the microstructure shear probe, CTD sensors, bio-optical sensors and high-resolution thermistor FP07.

TurboMAP-G is a quasi-horizontal glider-type profiler that will help researchers better understand bio-physical phenomena in the upper ocean.

YODA Profiler

YODA Profiler (Yoing Ocean Data Acquisition Profiler), which was developed by the Laboratory of Ocean Ecosystem Dynamics, is a new, portable tow-yo instrument that observes fine-scale features in coastal areas. The YODA Profiler’s ability to make continuous observations in shallow coastal areas and to be operated from a small boat sets it apart from past profilers.

CTD

CTDRecovering the CTD, from the Seiyo-maru.

CTD stands for “Conductivity, Temperature, and Depth”. The CTD water sampler measures water temperature, salinity, and density, and in turn, this data helps researchers understand how the ocean’s physical properties affect marine life.

UCTD

UCTDAbout to deploy the UCTD from the Umitaka-maru.

The UCTD, also known as the Underway CTD (Conductivity, Temperature, and Depth), is a profiler that is able to gather conductivity, temperature and depth data while the ship is still moving. Conventional CTDs require that the ship stop at the deployment location, but the UCTD can be deployed which the ship is moving and recovered via a re-spooling mechanism.

XBT/XCTD

Both the XBT and XCTD are expendable probes that can be launched using the same launcher.

The XBT (expendable bathythermograph) observes the vertical distribution of water temperature, with depth data calculated from elapsed time.

The XCTD (expendable conductivity, temperature, depth) carries conductivity, temperature, and depth sensors in order to observe the vertical distribution of water temperature and salinity.
