Br, Na, and I concentration in ice core DSS0506
A 258 m deep ice core was drilled using a 20 cm diameter thermal drill near to the Law Dome summit in November 2005 (Burn-Nunes et al., 2011). The core, designated DSS0506, was subsampled in October 2006 in a cold laboratory in a storage freezer in Hobart. For each ~1 metre long section of ice, a 35...
