PRELIMINARY DISCUSSION OF PHYSICAL PROPERTIES OF THE DOME FUJI SHALLOW ICE CORE IN 1993, ANTARCTICA

To make a pilot-hole for deep core drilling at Dome Fuji Station, East Queen Maud Land, Antarctica, shallow ice core drilling was conducted to a depth of 112.59m by electro-mechanical drill. Core logging, measurements of impermeability and bulk density were conducted in situ and most of another anal...

Description
Summary:To make a pilot-hole for deep core drilling at Dome Fuji Station, East Queen Maud Land, Antarctica, shallow ice core drilling was conducted to a depth of 112.59m by electro-mechanical drill. Core logging, measurements of impermeability and bulk density were conducted in situ and most of another analysis was done in Japan. Much depth hoar developed at Dome Fuji Station. However, it did not influence the densification rate, which mainly depends on temperature. Air bubble close-off starts from about 90m depth. Much accumulation at one time occurs during marine cyclones at Dome Fuji Station.
