Nitrate profiles in snow on sea-ice collected during SIPEX II
Listed in NASA Earthdata CMR
This dataset contains measurements of nitrate in snow on the sea-ice.
Description
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.
