Deepest Core Drilled From Antarctic Peninsula; May Contain Glacial Stage Ice
April 12, 2010
A new core drilled through an ice field on the Antarctic Peninsula may contain ice dating back into the last ice age. If so, that record should give new insight into past global climate changes. The expedition in early winter to the Bruce Plateau, an ice field straddling a narrow ridge on the northernmost tongue of the southernmost continent, yielded a core that was 445.6 meters (1,462 feet) long, the longest yet recovered from that region of Antarctica.
