Nitrate profiles in snow on sea-ice collected during SIPEX II
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. A...
