Sea ice Trace Metals sampling during the SIPEX II voyage of the Aurora Australis, 2012
Progress Code: completed Statement: Station 2 : Core 5 originally sampled for Trace Metal (tripled bagged) has been used for the Ice texture by mistake. The Core 4 is the only one cleaned (inner bag rinsed with milli-Q water). Station 3 : Difficult station due to cold temperatures and thickness of t...
