SHALLOW DRILLING ON THE ANTARCTIC CONTINENTAL MARGIN

Project Description
The understanding of Antarctica's climate, cryosphere, and biosphere evolution is limited, which is due in part to the paucity of outcrops and cores that record changes during the Tertiary. This problem has been partially rectified using conventional drill ships, such as the JOIDES Resolution, but access to key areas of the continental margin has been restricted because of the inability of these ships to operate in ice-covered waters. While researchers are restricted in their ability to acquire long cores in ice-prone areas, nature has provided an alternative method.
