Comment:
In austral summer 2012/2013, a 30 m firn core was drilled at DSS, Law Dome using the 4- inch Kovacs Mark VI coring system (Roberts et al., 2015). The firn core was transported to Hobart, Australia, and subsampled in the freezer at the Australian Antarctic Division (AAD)/Antarctic Climate and Ecosystem CRC (ACE CRC). For each 1-metre length of firn, a 35 mm x 35 mm stick was cut and sent to the Trace Research Advanced Clean Environment (TRACE) laboratory at Curtin University of Technology, Perth, Western Australia, for bromine determination. A parallel 35 mm x 35 mm stick was decontaminated and analysed for trace ions at the AAD/ACE CRC in Hobart, with a parallel section analysed for stable isotopes of water. Data covering the full depth range of the firn core are reported here, covering the period from summer 2012/2013 to late 1987 and overlapping with the DSS0506 record.
