Entity: East Antarctic margin of the Southern Ocean
Triple: [Adélie Coast region, isPartOf, East Antarctic margin of the Southern Ocean]

The East Antarctic margin of the Southern Ocean is the remote, ice-dominated oceanic boundary fringing East Antarctica, characterized by extensive continental shelves, strong katabatic winds, and crucial roles in global ocean circulation and climate.
