The predicted increase of ground temperatures in the Arctic results in the deepening of the active layer and intensification of geochemical processes. Determining the responses of riparian soil systems to surrounding hydrological flows is important for understanding seasonal changes in hydrological processes. In this study, one soil core from a polygon rim (close to the Taz River, TA) and two soil cores from a riverine terrace (close to the Syoyakha River, SY and Murtyyakha River, MU) in Western Siberia, Russia, and their suprapermafrost water, adjacent surface flows, and river water were sampled for analysis of geochemical elements. Results showed that most elements above their respective detection limits began accumulating in the underlying gleyed layer during September‐October in response to the deepest thaw in the active layer. This study focused on the highly mobile elements in the deepest layer; and found that the transport of organic matter in the upper layer carried these elements to both surface water ponds/flows and suprapermafrost water, and further, to the rivers. The efflux of released elements from surface soil to surrounding surface water appeared to be low. The best linear correlation for both surface flows and river water was with Mn; therefore, Mn may be a proxy for predicting the processes occurring within the active layer during the annual summer‐autumn thaw. Moreover, landscapes with different ice contents may experience changes in the elements transported to surface waters. A general conceptual model for the response of elements to the thawing‐freezing process of the active layer is established.

在俄罗斯北极多年冻土活动层中，地球化学元素向地表水的动员

预计北极地区地面温度的升高会导致活性层加深和地球化学过程加剧。确定河岸土壤系统对周围水文流量的响应对于了解水文过程的季节性变化非常重要。在这项研究中，俄罗斯西伯利亚西部的一个多边形边缘的一个土壤核心（靠近塔斯河，塔斯马尼亚州）和河流阶地的两个土壤核心（靠近西伯利亚的Syoyakha河和MU和Murtyyakha河）及其对超霜冻水，邻近地表水和河水进行了采样，以分析地球化学元素。结果表明，响应于活性层中最深的融化，大部分高于其各自检测限的元素在9月至10月期间开始在下面的褶皱层中积累。这项研究的重点是最深层中高度移动的元素。发现上层有机物的运输将这些元素带到地表水塘/水流和超霜冻水，再到河流。释放元素从地表土壤到周围地表水的流出似乎很低。地表水和河水的最佳线性关系是Mn。因此，Mn可能是预测每年夏季-秋季融化过程中活动层内发生的过程的代名词。此外，含冰​​量不同的景观可能会经历运输到地表水的元素的变化。建立了元素对活性层解冻过程响应的通用概念模型。发现上层有机物的运输将这些元素带到地表水塘/水流和超霜冻水，再到河流。释放元素从地表土壤到周围地表水的流出似乎很低。地表水和河水的最佳线性关系是Mn。因此，Mn可能是预测每年夏季-秋季融化过程中活动层内发生的过程的代名词。此外，含冰​​量不同的景观可能会经历运输到地表水的元素的变化。建立了元素对活性层解冻过程响应的通用概念模型。发现上层有机物的运输将这些元素带到地表水塘/水流和超霜冻水，再到河流。释放元素从地表土壤到周围地表水的流出似乎很低。地表水和河水的最佳线性关系是Mn。因此，Mn可能是预测每年夏季-秋季融化过程中活动层内发生的过程的代名词。此外，含冰​​量不同的景观可能会经历运输到地表水的元素的变化。建立了元素对活性层解冻过程响应的通用概念模型。
