Sea-floor videos and photographs (benthos) along 6 shelf profiles from the eastern Weddell Sea, Antarctica taken with remote operated vehicel CHEROKEE during Polarstern cruise ANT-XXI/2

The ROV operations had three objectives: (1) to check, whether the \"Cherokee\" system is suited for advanced benthological work in the high latitude Antarctic shelf areas; (2) to support the disturbance experiment, providing immediate visual Information; (3) to continue ecological work that started in 1989 at the hilltop situated at the northern margin of the Norsel Bank off the 4-Seasons Inlet (Weddell Sea).
