Short summary
We evaluate the local-scale variability of a sulfate profile at a low-accumulation site (Dome C, Antarctica) to assess the representativeness of one ice core for volcanic reconstructions. Peak statistical occurrence, depth and flux variability are evaluated from five cores. Due to local-scale variability, 64 volcanic peaks can be identified by a five-cores analysis, while only half of them can be assessed from two cores. Using five cores, the uncertainty of the mean flux is reduced to 29 %.
