2010-2011년 중부 아문젠해 대륙붕상의 관측

Abstract

In December 2010 and January 2011, Korea Polar Research Institute conducted a hydrographic survey in the central Amundsen Sea shelf near Gets and Dotson Ice Shelves using the new Korean IBRV Araon. The CTD data reveal that the near bottom intrusion of the Circumpolar Deep Water (CDW) into the shelf area is relatively weaker than the previous observations reported in various literatures. Vertical distributions of water properties on the cross (channel) section appear to incline slightly to the eastern flank of the channel suggesting that a physical process governs its synoptic circulation in the region. Possible physical processes for the CDW intrusion and synoptic circulation in the central Amundsen Sea shelf will be presented.Near bottom intrusion of the Circumpolar Deep Water (CDW) into the shelf area is relatively weaker than the previous observations reported in various literatures.
