Abstract
Abstract Snow samples from two snow-pits, located at different altitudes and distances from the sea, were analyzed to establish the H2O2, NO3 −, Cl−, SO4 2-, nss SO4 2- and MSA concentrations. The mean annual accumulation rates were calculated from the layer dating based on the H2O2 depth profile. The seasonal trends of the examined components' time series are discussed. The results obtained for the two stations are compared and found to be coherent. MSA appears to be the most promising seasonal tracer for the Terra Nova Bay region which is characterized by a strong marine contribution.
