Abstract

: The objective of this work is to demonstrate the results of hydrogeochmical studies carried out in the Steinvik River catchment for the first time, in order to provide detailed information regarding the chemical composition of groundwater in the Hornsund region, SW Spitsbergen. The water chemistry in the non-glaciated Steinvik River catchment is largely controlled by hydrological processes related to thaw of the near surface permafrost. Groundwater runoff is generated from the fast flow through well-permeable active layer. Recharge from melting snow, permafrost and rain, together with short residence time of groundwater, favors the forming of low-mineralized water, reaching 41 and 50 µS/cm for surface and groundwater, respectively, with the dominance of HCO 3− , Cl − , Mg 2+ , Ca 2+ and Na + ions. In some water samples, increased concentrations of aluminum (up to 268 µg/L ) were found. The highest concentrations of phosphate, nitrite and ammonium in water seem to be related to the presence of bird colonies. Groundwater of active layer in the studied catchment belongs to young meteoric water with the age limited to one summer season.
斯匹次卑尔根西南施泰因维克河流域活动层水化学的形成
这项工作的目的是首次展示在施泰因维克河流域进行的水文地球化学研究的结果,以便提供有关斯匹次卑尔根州西南霍恩松德地区地下水化学成分的详细信息。无冰川的施泰因维克河流域的水化学在很大程度上受与近地表永久冻土融化有关的水文过程的控制。地下水径流是由快速流过渗透性良好的活动层而产生的。融雪、冻土和雨水的补给,加上地下水停留时间短,有利于形成低矿化水,地表水和地下水矿化水分别达到41µS/cm和50µS/cm,以HCO 3−、Cl−、Mg 2+、Ca 2+和Na +离子为主。在一些水样中,发现铝的浓度增加(高达268微克/升)。水中磷酸盐、亚硝酸盐和铵的最高浓度似乎与鸟类群落的存在有关。研究流域活动层地下水属于年轻的大气水,年龄限定在一个夏季。
