ANTXXII-2

• The 50-day drift station will be performed during the Polarstern cruise ANT XXII/2 (6 Nov. 2004 to 19 Jan. 2005) The ship will be anchored to an ice floe and will serve as a base for field work, while drifting with the floe in the target area (Fig. 1).
• The ship will depart from Cape Town, South Africa, and will enter the central Weddell Sea at about 60°S, 40°W, to steam as far to the Southwest as ice conditions allow. The anticipated final destination is 72°S, 50°W (southwestern Weddell Sea) in mid-November (Fig. 1). For that region, model results of drift trajectories have shown a high probability that the ship will still be within closed pack ice at the completion of measurements by mid-January.
• Two helicopters, three divers, and ship-based infrastructure will be available for larger-scale studies around, below, and at the ship.
• A camp consisting of Fibreglass huts will be put up on the floe to house equipment and to provide scientist with a 24 hour possibility to monitor their projects.
