Scientists have found a new species in the place where the Ob river flows into the Kara sea.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. The Russian Academy of Sciences Plant Physiology Institute’s specialists found an unknown species of diatoms in the place where the Ob flows into the Kara sea. They were named after Arctic explorer Pyotr Shirshov – Fragilaria shirshovii.

During the expedition of the floating university, researchers led by Nikolay Lobus, a senior researcher at the institute, studied the water area where fresh water mixes with salt, TASS writes. The new species belongs to the genus Fragilaria, whose representatives live in both freshwater and salt water bodies, but differ markedly from their congeners. According to scientists, this allows it to be used as an additional tool for monitoring the state of the environment. The species diversity of diatoms is largely dependent on water quality.

Earlier, the Arctic Floating University explored the Sopochnaya Karga cape in Taimyr for the first time. In the north of Novaya Zemlya, ornithologists have discovered a new colony of kittiwakes.
