Offshore Surface 402 Oyashio current, subarctic waters (offshore)

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.

Basic Information A separate window opensReferences

Area (km2) 4107

Reason(s) for selection A separate window opensCriteria

Selected due to high levels on the criteria 5.

Characteristics A separate window opensReferences

While the waters of No. 402 can be considered to have characteristics similar to those of the waters of No. 401, they have been chosen as separate waters based on the results of analysis.

(Note: While these waters were selected based on the results of analysis using data and analytical methods available as of FY2011–2013, this creates some issues such as the fact that locations that could be considered continuous in terms of their ecological characteristics may be split by automatic analysis.)
