| Summary: | "Measurements started in 1997 and are still on going. From 1997-2011 water samples were taken everyday at 8 am and 8 pm. From 2012-present water samples are taken three times a week at 8 am and at 8 pm. Water temperature and conductivity is measured in situ, using a YSI 30 conductivity meter. Water samples from 8 am are analyzed for pH and alkalinity in the laborratory facilities at the Zackenberg station. Cooled water samples (from 8 am) are transported to Denmark and analyzed in the laboratory at the Department of Geosciences and Natural Resource Management, University of Copenhagen, for the folowing anions and cations: Chloride, Sulfate, Sodium, Magnesium, Potassium, Calcium, Iron and Aluminum. The detection limit for all these ions is 0.1 ppm. Concentrations below this threshold have been set to 0.000. Furthermore a 20 ml subsample is taken once a week from the 8 am water sample. This sample is kept frozen and brought to the Department of Biology, University of Copenhagen, where it is analyzed for ... |
