Towards Fruitful Academic Exchange between Japan and Russia
Nobuyuki MIYAZAKI
Professor Emeritus, The University of Tokyo / Chief Researcher, Ocean Policy Research FoundationContinuing the active international exchange activities at the researcher level between Japan and Russia, the 6th Conference "Marine Mammals of Holarctic Ewas held in Russia in October of 2010. In order to maintain good relations between Japan and Russia in future, personnel and academic exchanges such as this, along with an even broader range of cultural exchanges, should be vigorously promoted at the national level. It is important that such activities develop toward the shared goals of peace and prosperity of mankind. -

Climate Variation: Sea-ice Distribution History and the Integrated Ocean Drilling Program
Kozo TAKAHASHIProfessor, Department of Earth & Planetary Sciences, Graduate School of Sciences, Kyushu University / Board of Governors, Integrated Ocean Drilling Program / Recipient, 3rd Annual Maritime State Distinguished Service Award (Prime Ministers Medal)
The partial opening of the Northwest Passage due to the decline in arctic ice coverage caused by global warming is an example of the large impacts on human activities of ocean ice distribution. Boring operations by the Integrated Ocean Drilling Program (IODP) in the Arctic Ocean and Bering Sea have provided valuable samples for reading the history of sea ice formation, which in turn holds the key to climate variation. From discovering details of earth activities in warmer eras, to clarifying the mechanism for establishing the glacial-interglacial cycles, the large role is played by IODP research.
