Dissolved inorganic nutrient concentration of Lena River water from 20.04.2018 (#1) to 11.09.2019 (#201)
We collected water samples from the river surface in the center of the Olenekskaya Channel near Samoylov Island using a pre-rinsed HDPE 1 L bottle. During the open water period (June to October), water was sampled from a small boat, and during ice-covered period (November to May), through a hole dri...
