| Outline of Final Research Achievements |
We developed a parasite deep-sea observatory embedding into an ocean bottom seismometer to observe time-series changes of hydrodynamic currents, activities and density of benthic organisms related to the surface primary production changes at sea surface, and bioturbation processes. This observatory consisted of an embedding microprocessor board with camera and a low power consumption timer. We deployed two ocean bottom seismometer with the observatories on R/V Kairei KR17-04 cruise and succeeded the continuous observation from 10-20 days. We also planned to mount a CTD (digital XBT) with underwater wireless communication used with a rubber material. With the basic experiment used with an aquarium, we confirmed the Wi-Fi communication, and we concluded the observatory can be extended for a purpose of long term monitoring of temperature and salinity at sea bottom.
