The areas in the Weddell Sea are various icebergs. The most important is Special Iceberg A sm-16p. Inside this iceberg is the Iceberg Cavern. The entrance to the cavern is Lower Ice Cave 3. Also on the outside of the Iceberg is Upper Ice Cave 2. Upper Ice Cave 2 does not lead anywhere and does not serve as much importance as Lower Ice Cave 3 Animals that can be found here include Southern Bottlenose Whales, Orcas, Cape fur seals, and Emperor Penguins .
