We capture the rapidly-changing global environment with the power of technology

OFFSHORE TECHNOLOGIES develops and manufactures oceanographic instruments and provides consulting services for the development of observation equipment.
The oceans occupy 70% of the earth's surface. Therefore understanding the ocean essentially leads to the understanding of our planet.
We aim to use the power of technology to capture environmental changes and change people's lives for the better.

A research paper using the compact CTD sensor “JES10mini” was published

A research paper using the compact CTD sensor “JES10mini” was published in the academic journal “Polar Data Journal”. “JES10mini” was used for observations in the Arctic Ocean by a research team from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and the Geophysical Institute University of Alaska Fairbanks.
The Pacific sector of the Arctic Ocean is experiencing sea-ice reduction, yet there are not many ocean observations beneath sea ice. In this study, an ice-tethered buoy monitored CTD, phytoplankton biomass, and photosynthesis available radiation (PAR), and GPS buoys monitored sea ice motions in the Beaufort Sea. A ice-tethered buoy was equipped with four “JES10mini” at different depths.

Multipurpose Observation Float（MOF）
A relatively compact and user-friendly float that can automatically ascend and descend in the sea during observation. Equipped with a CTD sensor, it observes salinity, water temperature, and depth in the sea. The observation data is automatically transmitted when it rises to the surface, and can be received on land.

Multipurpose Observation Glider（MOG)
A relatively compact and user-friendly underwater glider that can automatically ascend and descend to a designated observation point without being moored to the seafloor. It is equipped with a CTD sensor to observe salinity, water temperature, and depth in the sea.

CTD sensor JES10mini
JES10mini is a small CTD sensor for observing salinity, temperature and depth in the sea. It is compact and lightweight, and can be cast simply using a fishing tackle.
It can be activated, set up, and read out data via Bluetooth communication. The Japanese-language operation system ensures ease of use.
