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 cover

Data collection

Data collection 1

Mode of collection: Physical measurements and tests
Description of the mode of collection: The sampled river waters were filtered in situ through 0.45 /um filters using a peristaltic pump. The filtered samples were then acidified with 25 ml of ultrapure HCI. All bottles, tubing, filters and filter holders were acid-cleaned before use.
Time period(s) for data collection: 1991-04 – 1992-09

Data collection 2

Mode of collection: Physical measurements and tests
Description of the mode of collection: The samples in 2013 were collected from the coast guard vessel KBV005 with 2 × 2 L Niskin bottles (Hydros-Bios, Kiel, Germany, which had been custom-made trace metal clean and contained only Ti screws, on a Dyneema rope, acid-cleaned 2-L LDPE bottles - all parts acid cleaned), on a line at depths of 0.5, 5 and 10 m. In 2014, the samples were collected through a hole in the ice, drilled with an ice auger and pumped up from depths of 0.5, 5 and 10 meters.
Time period(s) for data collection: 2013 – 2016

Geographic coverage

Geographic spread

Geographic location: Sweden, Norrbotten County, Kalix Municipality

Geographic description: The Kalix River and the Kalix River estuary were sampled, at 4 different sampling locations. Latitude and longitude points of each sample are included in the "Sampling Information" tabs within the dataset for each sampling event.
