Figure 4: oI3e data of POM of the Lena (a), Yana (b), and Khatanga (c) (black circles) and their major tributaries
(white circles). The scale on the x·axis corresponds to the distance (river-km) of the station from the river
mouths. For the tributaries the distance between confluence and mouth is given. Average ol3e values of the
Lena, Yana, and Khatanga are indicated by dotted lines. The shaded areas represent the standard deviation of ol3e
values within the rivers except for the tributaries.
