Introduction:

The Seal Nunataks are a group of 16 nunataks emerging from the Larsen Ice Shelf east of Graham Land Peninsula. The Seal Nunataks have been described as separate volcanic vents or remnants of a large shield volcano. Fumarolic activity was reported from Murdoch and Dallman cones in 1982, and fresh-looking pyroclastics and a lava flow at Dallman (not observed in 1979) were seen on the ice surface three years later (González-Ferrán 1983). Fumarolic activity was observed at Christensen in 1893, and Lindenberg was observed in eruption in 1893. Baker (1968) saw cinders on the ice surface, suggesting a 20th-century eruption. A 1988 British expedition noted that tephra away from nunataks was found only in ice-cored moraines, suggesting a glacial rather than pyroclastic origin. They noted no fumarolic activity, although water vapor resulting from radiant heating of ice-cored moraines was observed.
