Kalix River Geochemistry

This dataset contains element concentrations of quantitative element screenings (ICP-MS, 70+ elements) conducted on filtered water samples and the filtered material (cut-off 0.22 μm) from samples taken in the Kalix River and in the Kalix River Estuary during three sampling campaigns (2013, 2014, and 2016). The purpose of the study was to observe changes in the dissolved and particulate element concentrations during spring flood and along a slowly increasing salinity gradient. This dataset also contains Strontium Isotope data collected in the Kalix River in 1991 and 1992.

Water samples from the Kalix River estuaries were collected during the spring flood in February, March, and April 2014, in May and June 2013, and in May, June, and July 2014. Water samples from the Kalix estuaries were collected from the coastguard vessel KBV005 in May and June 2013. Water samples from all sampling stations were collected at a depth of 0.5, 5, and 10 meters, if they were deep enough. At the sampling in March 2014, samples were collected from the first three stations in the estuaries when they were still covered with ice. In 2014, the tests were carried out through a hole in the ice, drilled with an ice drill, and pumped up from depths of 0.5, 5, and 10 meters.
Water samples from the Kalix River during the spring flood 2016, from March to July. In Kalixälven, at the sampling station Kamlunge, samples were collected from a bridge in the middle of the river.
In 1991 and 1992, samples were taken to detect strontium isotopes.
