The oceanographic structures of the Antarctic Ocean off Lutzow-Holm Bay during the austral summer are described, based primarily upon observations taken aboard the icebreaker Fuji of the 15th Japanese Antarctic Research Expedition from 1973 to 1974. The oceanographic features are revealed by analysis of temperature, salinity, dissolved oxygen and nutrients. It is clarified that the westward-flowing current dominate near the coast side and the eastward-flowing current dominate over the broad area off the coast. The former area as well as the sea above the continental shelf slope has possibility of Antarctic Deep Water formation. The latter area are strongly affected by the Antarctic Circumpolar Current. Especially in the deep layer, the water shows low temperature,fairly high salinity concentration and high concentration of dissolved oxygen. The water may originate from the Weddell Sea. Circumpolar Deep Water flows eastward and changes the characteristics with the mixing of North Atlantic Deep Water and Continental Shelf Slope Waters.Journal
