| Outline of Final Research Achievements |
We expect that the ship passage period through the northern sea route (NSR) will be further extended because the sea ice area in the Arctic Ocean has recently tended to decrease tendency. As a preliminary study to understand the passage possibility through the NSR, the navigation simulation is performed under the sea ice decrease with the sea ice concentration and wave reanalysis. In this simulation, the area where sea ice concentration is more than determined value denotes no passage one. The continuous passage period through the NSR ranges roughly from the end of August to the end of September of each year during 2009 to 2011. The route selection to pass through the NSR is more important than that to save the passage time on the NSR. The strategy to wait for sea ice conditions is effective to pass through the NSR.
