A hydrographic survey in the central Amundsen sea shelf in 2010-2011.

Abstract

In December 2010 and January 2011, Korea Polar Research Institute conducted a hydrographic 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.r than the previous observations reported in various literatures.
