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.本数据集涵盖通过定量元素筛查（采用电感耦合等离子体质谱法(ICP-MS)，可检测70余种元素）获得的元素浓度数据，采样对象为勒奈河(Råne River)及其河口采集的过滤水样与截留孔径0.22 μm的过滤截留物，采样工作共开展3轮，分别于2013年、2014年及2016年完成。本研究旨在探究春季洪水期及盐度缓慢升高梯度下，溶解态与颗粒态元素浓度的变化特征。 勒奈河河口水样的采集时段包括：2013年5月、6月，2014年2月、3月、4月的春季洪水期，以及2014年5月、6月、7月。2013年5月、6月的勒奈河河口水样由KBV005号海岸警卫艇采集。若采样站位水深足够，均会采集0.5米、5米及10米深度的水样。2014年3月的采样中，河口前3个站位仍被冰层覆盖，研究人员通过冰钻钻孔，并将水样从0.5米、5米及10米深度泵取完成采样。 2016年春季洪水期（3月至7月），采集了勒奈河干流的水样。在勒奈河的Orrbyn采样站位，水样取自河中央的桥梁位置。
