Snow fields of the coastal Antarctic region are situated intermediately between the vast environmental regimes of the high antarctic plateau and that of the South Polar Ocean. Since they are directly exposed to moist maritime air masses, a relatively high snow accumulation rate, associated with the deposition of mainly marine derived aerosol species, is expected here. These characteristics make this region unique to recover high resolution ice core records that reveal the environmental and climatic history of the South Polar Ocean. Indeed, several extensive ice core studies have been or are currently performed in coastal antarctic regions (see Figure 1). To “calibrate”, in particular, their glacio-chemical information in terms of the corresponding atmospheric changes, representative long term records of the coastal antarctic aerosol chemistry (including the relevant precursor gases) are needed.
