'''[[Siple Dome]]''' is an [[ice]] dome approximately 100 km wide and 100 km long, located 130 km east of [[Siple Coast]] in [[Westarctica]]. Charles Bentley and Robert Thomas established a "strain rosette" on this feature to determine ice movement in 1973-74. They referred to the feature as Siple Dome because of its proximity to Siple Coast.
The '''[[Backer Islands]]''' are a chain of small islands at the south side of [[Cranton Bay]]. The islands trend northwest for 22 kilometers (12 nmi) from the [[ice shelf]] which forms the southern limit of the bay.


A documentary on climate change research associated with the Siple Dome ice core was produced by Nova: Warnings from the Ice, 1998. The documentary explains how reductions in Antarctic ice mass can raise sea level.
In 2011, scientists from the POLar Earth-observing NETwork (POLENET) traveled to the Backer Islands via a Twin Otter aircraft and installed a GPS monitoring site. This equipment is used to remotely monitor GPS and seismic data that will help scientists determine trends in ice sheet movement and other geophysical phenomena.


Siple Dome is referenced in the song "Fall of Sipledome" by thrash metal band Testament (on their 1999 album ''The Gathering'').

The Backer Islands are a chain of small islands at the south side of Cranton Bay. The islands trend northwest for 22 kilometers (12 nmi) from the ice shelf which forms the southern limit of the bay.

In 2011, scientists from the POLar Earth-observing NETwork (POLENET) traveled to the Backer Islands via a Twin Otter aircraft and installed a GPS monitoring site. This equipment is used to remotely monitor GPS and seismic data that will help scientists determine trends in ice sheet movement and other geophysical phenomena.
