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