Improvements of oceanic and atmospheric measurements on the TRITON buoy

As it takes about ten years since the current TRITON buoys have started being deployed, the current buoys were rather senescent. It has been necessary to develop new measurement equipments for the TRITON buoy. This study introduced the current situation on the development of meteorological sensor systems, water temperature sensor systems, and underwater non- contact data transmission system, which are developing or have been developed in JAMSTEC in the past three years. New meteorological sensors have already been used as a part of the current TRITON system, and have been transmitted data at the same high quality as from the old systems. New water temperature sensor system and no-contact underwater data transmission system is currently under development; however the results of technical experiments indicate the possible high performance towards better observations.
