| Outline of Annual Research Achievements |
Dissolved oxygen loggers and temperature loggers were setup at 5 sites. Daily photosynthetic photon flux density and wind speed was also monitored. Two sites were setup at Undaria pinnatifida farms in Matsushima Bay and Hirota Bay, one site was at a Cladosiphon okamuranus farm at Bise point, and one site was at a natural seaweed bed in Arikawa Bay.
Our research revealed distinct variations in oxygen concentrations due to differences in the photosynthetic ability among the 5 sites. Bayesian models are being redesigned to address these differences. Some of the results of our work are being presented at national conferences and scientific manuscripts.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
Data collection and analysis is proceeding as planned with little problems during field work.
|
| Strategy for Future Research Activity |
We plan to continue our field work and monitoring. No changes are planned to any protocols, due to the steady stream of high quality data.
