FUTURE OF SAKHALIN LAGOONS

09.04.2019

On April 14, the next lecture on «The Historical Development of the Nature of Sakhalin» will be held. It’s about lagoons. The lagoons are unique and original components of the geosystem of Sakhalin Island, where processes are associated primarily with the development of salmon.
Lagoons were formed relatively recently, their history is closely connected with the Holocene transgression in the World Ocean. About 7–5 thousand years ago, when the level of the Sea of Okhotsk exceeded +10 m above the current, sea waters penetrated into the depressions of the modern lagoons of southern Sakhalin. Accumulative forms separating lagoons from the sea were absent at that time, and the lagoons were shallow bays with warm water.
Nowadays lagoons are being affected by human activities. Lake Nevskoe became overgrown with aquatic and marsh vegetation, its productivity drops. In Lake Tunaicha, despite of its status of natural monument, changes in the lake hydrology, including biota, are noted.
The Candidate of Geographical Sciences, Chief Researcher of the Sakhalin Regional Museum, Sergey Mikhailovich Pervukhin will tell you about this and many other things in detail.
