A calendar combining elements of marine science and astronomy to track the phases of the Moon any day. It has been carried out in an endless calendar format, making it relevant for many years. The calendar contains maps illustrating the dynamics of the moon tides and the tides of the Russian seas.



As an annex to the calendar, there are 13 cards showing the approximate dynamics of the tides and tides of the Russian seas as of January 2026.
Why just for January? Because it is impossible to trace this natural phenomenon to the future — the weather is too variable. These cards will be issued monthly to the partners of the Centre for Underwater Studies of the Russian Geographical Society as a souvenir product.
Trends in the tides and tides of the Russian seas as of January 2026.
Seafarers use special signs on maps to indicate a variety of objects and phenomena. These symbols were integrated into the design of the project not only for decoration, but also for the streamlining and labelling of Russian seas, whose tides and tides are represented on the host.
