Abstract
Coastlines along the Sea of Okhotsk in Hokkaido are the southernmost regions in the northern Pacific Ocean where sea ice reaches the coast. It has been demonstrated that global warming affects and decreases the ice cover area in the Sea of Okhotsk. This study thus aims to investigate the relationship between sea ice and waves in the Sea of Okhotsk by analyzing ice cover area, sea ice volume, significant wave height and significant wave period. Additionally, we made an attempt to clarify trends in ice cover area and sea ice volume from 1989 to 2012 using satellite images. Sea ice volumes in the northern part of the Sea of Okhotsk correlate with significant wave height and significant wave period. Furthermore, ice cover area and sea ice volume have decreased since 2001 or 2002, which may enhance wave action during winter.
期刊介绍：
Cold Regions Science and Technology is an international journal dealing with the science and technical problems of cold environments in both the polar regions and more temperate locations. It includes fundamental aspects of cryospheric sciences which have applications for cold regions problems as well as engineering topics which relate to the cryosphere.
Emphasis is given to applied science with broad coverage of the physical and mechanical aspects of ice (including glaciers and sea ice), snow and snow avalanches, ice-water systems, ice-bonded soils and permafrost.
Relevant aspects of Earth science, materials science, offshore and river ice engineering are also of primary interest. These include icing of ships and structures as well as trafficability in cold environments. Technological advances for cold regions in research, development, and engineering practice are relevant to the journal. Theoretical papers must include a detailed discussion of the potential application of the theory to address cold regions problems. The journal serves a wide range of specialists, providing a medium for interdisciplinary communication and a convenient source of reference.
