-'''[[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. They were mapped by the United States Geological Survey from surveys and from [[U.S. Navy]] air photos, 1960–66, and named by the Advisory Committee on Antarctic Names for Walter K. Backer, a U.S. Navy chief construction mechanic at [[Byrd Station]] in 1967.
-The Siple Dome ice core project was conducted by the United States National Science Foundation. The deepest ice was recovered in 1999 from 974m, with an age of 97,600 years. It is best known for the poorly-explained steps in water isotopes during the deglacial, which are unique to this core and may indicate a rapid decrease in the surface elevation of the adjoining [[Ice Stream|ice stream]]s during the deglacial and a record of atmospheric carbon dioxide.
+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.
