Nitrate profiles in snow on sea-ice collected during SIPEX II
This dataset contains measurements of nitrate in snow on the sea-ice. These vertical nitrate profiles were collected from snow pits that were dug at each ice station during the SIPEX II voyage in 2012. The snow depths range from 25-55 cm and snow samples were collected in 5 to 10 cm intervals from the snow surface to the top of the sea-ice. The snow was then melted and passed through a resin to collect the nitrate. The nitrate was then eluted with a strong NaCl solution and kept in bottles that were frozen at -20 degrees C. The samples were shipped frozen back to Seattle where they will be analysed using an ion chromatograph. The ion chromatograph outputs the data as text files.
At this stage, samples have been collected but not analysed so no data currently exists.

Resource lineage
- Statement
- Our sampling techniques got better with each ice station, but at the first few ice stations there was a considerable amount of lint in our snow samples. The lint was likely from our gloves. The lint can be carefully removed from the filters once back in Seattle so our results will not be affected. At Ice Stations 1, 2, 3, 4, and 7 we collected bags of snow on top of the sea ice with ~2-10 cm vertical resolution. These are the same snow samples that were used for insoluble light absorbing particle analysis and described in Zatko and Warren [2015] (see referenced paper). We measured the nitrogen and oxygen isotopic composition of the nitrate contained in the snow. Our technique also provides some estimate of nitrate concentration, although we do not fully trust the concentration measurements. The attached spreadsheet contains the nitrogen and oxygen isotopic information. We were able to perform duplicate measurements on most samples.
