Offshore Surface 408 Ogasawara vicinity waters

Note; The offshore surface areas have many physically fluid factors such as ocean current or seasonal changes, which may effect on the spawning grounds or distribution areas of certain organisms. Therefore, it is difficult to fix certain area as EBSAs of offshore surface spatially. In addition, available data for analysis are very limited. Therefore, the EBSAs of offshore surface shows the probabilistic distribution of important area as a result of mechanical analysis using best available data at the time, so that there are problems such as that some places considered to be consecutive from the ecological features are divided. Further analysis will be required to improve when the data became available in the future, and it is necessary to review the analysis method.
