It is believed that the waters of rivers flowing into the Kara Sea (predominantly discharge of the Yenisei and Ob rivers) can propagate to the east, penetrating the Laptev Sea with the current along the coast. This can occur with the so-called eastern transfer of continental runoff. During a cruise of the R/V Akademik Mstislav Keldysh in 2018, traces of riverine waters were discovered in the Vilkitsky Strait. Hydrochemical data suggest with great confidence that these waters were transported from the Ob–Yenisei estuary region. This is because in 2018, pronounced eastern transfer of water from the Kara to the Laptev Sea was observed. A year earlier, continental runoff was not observed in the strait. The fact that transformed riverine waters were transported into the strait from the Kara Sea is also corroborated by the results of surface water sampling along the route of the vessel.

2017年9月和2018年通过Vilkitskiy海峡运输大陆径流

据信流入卡拉海的河流水（主要是叶尼塞河和鄂毕河的排放）可以传播到东部，并随着海岸的水流渗入拉普捷夫海。这可能发生在所谓的大陆径流的东部转移中。在R / V Akademik Mstislav Keldysh的巡游中2018年，在Vilkitsky海峡发现了河水痕迹。水化学数据很有把握地表明这些水是从Ob-Yenisei河口地区运来的。这是因为在2018年，观察到明显的东部水从卡拉到拉普捷夫海的转移。一年前，在海峡没有观察到大陆径流。沿船只路线进行的地表水采样结果也证实了将转化的河水从卡拉海运入海峡这一事实。
