Råne 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 Råne River and in the Råne 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. Water samples in the Råne 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 Råne River estuaries were taken from the coastguard vessel KBV005 in May and June 2013. Samples at all sampling stations were collected at 0.5, 5 and 10 meters deep if they were deep enough. At the sampling in March 2014, samples were taken from the first three stations in the estuaries while they were still covered with ice. In 2014, the tests were carried out through a hole in the ice. The hole was drilled with an ice drill and the samples pumped up from depths of 0.5, 5 and 10 meters. Water samples from the Råne River were collected during the spring flood 2016, from March to July. In Råneälven, at the sampling station Orrbyn, samples were taken from a bridge in the middle of the river.
