Event(s):
EDC (EPICA Dome C) * Latitude: -75.100000 * Longitude: 123.350000 * Date/Time Start: 1993-01-01T00:00:00 * Date/Time End: 2004-12-31T00:00:00 * Elevation: 3233.0 m * Recovery: 3300 m * Location: Dome C, Antarctica * Campaign: Dome C * Method/Device: Ice drill (ICEDRILL) * Comment: Drill site is 56 km from the site of a previous Dome C core that provided records extending into the last glacial period, and 560 km from the site of the Vostok cores. The completion of the Dome C core was delayed when the first drilling became stuck at 788 m in 1999 (EDC96).
Comment:
The timescale is EDC2, and the accumulation rates used to calculate flux also derive from EDC2. Non-sea-salt concentrations were calculated. We calculated ssNa and nssCa assuming a Ca/Na weight ratio of 0.038 for marine aerosols and 1.78 for the average crust. nssSO42- was derived assuming a SO42-/Na ratio in marine aerosol of 0.1 (appropriate for a sea ice surface, but note that the use of a traditional sea water ratio of 0.25 would not affect the results significantly).
Data presented in Wolff et al. (2006) were all too high by 8.3% because of an error with the accumulation rates: these are the corrected values.
