Research Information

Period and Interval
2017/04/01 - 2018/03/31
Routine survey (monthly) / Data logger & Observation buoy (continuous)
Research Area
Onagawa Bay
Category
Field survey, Mooring system(Observation buoy)
Overview
(1) Routine field surveys will be conducted to obtain physical, chemical and biological data in Onagawa Bay and they will be analyzed using GIS and other geo-statistical methods. (2) Archived data from Onagawa Nuclear Power Plant Annual Survey Reports will be assessed and subsets of relevant physical, chemical and biological data (1990 onwards) will be extracted and integrated into the whole analysis.

Results and Future Plan
(1) Routine field surveys (monthly) were successfully carried out as planned to obtain physical, chemical and biological data in Onagawa Bay. All the survey data collected from the beginning of FY2012 were also processed and analysed using GIS and other geo-statistical methods in order to visualize spatio-temporal patterns in the dynamics of Onagawa Bay ecosystem after the 2011 Tohoku Earthquake and Tsunami. (2) Archived data derived from Onagawa Nuclear Power Plant Annual Survey Reports were assessed and subsets of relevant physical, chemical and biological data for FY1990-2015 were extracted and processed. The long-term data were then analysed using GIS and multivariate methods in order to investigate spatio-temporal dynamics of Onagawa Bay ecosystem in response to the 2011 Tohoku Earthquake and Tsunami.
