The Siple Coast , engl. Siple Coast , is the central part of the Ross Sea coast of Marie Byrd Land in Antarctica . The entire coastline is bordered by the Ross Ice Shelf . The coastline is not clearly defined, as massive ice streams cover the land and flow into the ice shelf. These include the Bindschadler , Kamb and Whillans Ice Streams . These ice streams, which flow into the Siple coast, are flat, characterized by very low bed and surface slopes and strongly fluctuating dynamics.

The climatic conditions on the Siple Coast are characterized by frequent katabatic winds that blow from West Antarctica over the Ross Ice Shelf and play an essential role in the formation of the sea ice.

The coast was named after the Antarctic explorer Paul Siple (1908-1968), who took part in six Antarctic expeditions, including Richard Evelyn Byrd's first two expeditions to the Siple Coast (1928-1930). In addition to the Siple coast, the Siple Island and Mount Siple were named after him.

The part of the coast west of 150 ° West is claimed as part of the Ross Dependency of New Zealand.
