Figure 3. Mean annual chemical flux (in kilograms per square kilometer per year) in 1994-1995 and 1996-1997 Siple Dome snowpits (error bars represent standard error). The order of snowpits on the figure is along the transect from 30 km north (96-E) to 30 km south (96-F) of the ice divide. The method used to separate seasalt (ss) from nonseasalt [or excess (xs)] chemical fractions is given in Kreutz et al. (1997).
