Trace metal water column samples collected on the SIPEX II voyage of the Aurora Australis
This dataset will be comprised of measurements taken from trace metal water column samples collected during the SIPEX II Antarctic marine science voyage in 2012. In its current form no sample analysis has been performed. The dataset simply contains the log sheets for the Trace Metals Rosette (TMR) deployments as well as the output files from the TMR software (General Oceanics).
Water samples for dissolved trace metal measurements were collected from the surface (15m) down to the 1000m using an autonomous intelligent rosette system (General Oceanics, USA) specially adapted for trace metal work and deployed on a Dyneema rope. The rosette was equipped with 12x10-L Niskin-1010X bottles specially modified for trace metal water sampling. This system has been successfully deployed on the RSV Aurora Australis during voyages au0703 and au0806. Care was taken to avoid any contamination from the ship and the operating personnel. Water samplers were processed aboard under an ISO class 5 trace-metal-clean laminar flow bench in to a trace-metal-clean laboratory container on the ship's trawl deck. All transfer tubes, filtering devices and sample containers were rinsed liberally with sample before final collection. Samples were then drawn through C-Flex tubing (Cole Parmer) and filtered in-line through 0.2 micron pore-size acid-washed capsules (Pall Supor membrane, Acropak 200). Filtered and unfiltered samples were collected in acid-cleaned 125ml Nalgene LDPE bottles for analysis of dissolved trace metals. Samples were also collected for the determination of stable isotopes of nitrogen and carbon. As well, filtered samples were taken for macro-nutrient analysis in the lab (2 small vials per Niskin, frozen).
Regular sampling depths were as follows: 1000m, 750m, 500m, 300m, 200m, 150m, 125m, 100m, 75m, 50m, 30m, 15m.
At a subset of the SIPEX II ice stations, filtered samples were also collected for Iron(II) analysis aboard the ship by Christina Schallenberg (in the trace-metal-clean laboratory container), and unfiltered samples were collected for analysis of mercury and methyl-mercury by Caitlin Gionfriddo (caitlingio@gmail.com). caitlingio@gmail.com At a subset of the SIPEX II ice stations, filtered samples were also collected for Iron(II) analysis aboard the ship by Christina Schallenberg (in the trace-metal-clean laboratory container), and unfiltered samples were collected for analysis of mercury and methyl-mercury by Caitlin Gionfriddo (caitlingio@gmail.com).

Resource lineage
- Statement
- The following problems were encountered: TMR1 = had to come up faster during the ascent because we were running out of water behind the ship due to inbound sea-ice TMR2 = Bottle 11 didn't fire TMR3 = Bottle 7 didn't fire TMR4 = not a single bottle fired, we suspect due to the extremely cold temperatures TMR5 = weird yellow stringy things attached to the TMR when it came back up on deck; not biological, likely some kind of contamination from the ship TMR6 = Bottle 1 leaked from the bottom when the vent was opened for sampling TMR7 = no issues TMR8 = no issues
