OFFSHORE TECHNOLOGIES

Thank you for your continued cooperation this year and wish you a happy New Year！

We will be closed for the New Year’s holiday from December 29 through January 3.

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.

A research paper using the compact CTD sensor “JES10mini” was published in the academic journal “Sensors”. A research team conducted oceanic and atmospheric observations using a wave-propelled unmanned surface vehicle (Wave Glider), in the area off the Sanriku coast of Japan. Despite the severe weather conditions of atmospheric low-pressure system crossings, they succeeded in observing wind, air temperature, humidity, sea surface temperature and salinity etc. over the course of 55 days. In this observation, “JES10mini” attached to the wave glider is used to observe sea surface temperature and salinity.
