Studying the pigment composition of bottom sediments of the meromictic Lake Shira allows us to learn about the past of the reservoir. Analysis of carotenoids of frozen cores of the upper layers of bottom sediments, and comparison with field observations shows the relationship between the hydrological regime of the lake and the content of okenone, a carotenoid of purple sulfur bacteria.
