Scientists investigate Yamal "blue" lakes

Research and Innovations 26 December 2019

In the Nadym district of the Yamalo-Nenets Autonomous Okrug an investigation of peculiar "blue" lakes was conducted.

In order to understand the phenomena of this ecosystem, Tyumen scientists analyzed water samples and fauna chemical composition of the lakes. The results of the work were presented at the International Conference “Ecosystem Services and Natural Resources Management”.

To assess the status of water bodies, UTMN scientists studied the diversity of species, abundance and biomass of zooplankton present in two "blue" lakes. To do this, they collected samples from the water bodies by filtering water through a special sieve, and also by determining the basic chemical characteristics of water (content of iron, copper, nickel and others). 14 different species of zooplankton were recognized, only 38% of which were present in both lakes. The species discovered are typical for most bodies of water in Western Siberia. The most numerous and constantly occurring species is the Sida crystallina crustacean; and the other one present is considered quite rare in lakes of this type - Аnthocyclops vernalis.

“The zooplankton of the examined lakes has a clear resemblance to the zooplankton of other water bodies in the Yamalo-Nenets Autonomous Okrug, which was shown in the work. Since water invertebrates are good indicators of water quality, the data obtained can be further used for integrated environmental monitoring of the region’s water ecosystems”, — said Andrei Soromotin, Director of the Research Institute of Ecology and Rational Use of Natural Resources, University of Tyumen.
