Hydrodynamics and water exchange features of Blagopoluchiya Bay (Solovetsky Islands, White Sea)

Research on Blagopoluchiya Bay, part of the UNESCO-listed Solovetsky Islands, reveals significant seasonal variations in water exchange. The bay's water renewal period extends to 14 days during open-water seasons but exceeds 30 days during freeze-up, indicating restricted circulation during colder months. Turbulent diffusion within the enclosed bay is notably low (Kx ~0.02 m²/s), much less than typical shelf seas, suggesting unique hydrodynamic processes. The study analyzed in-situ measurements of temperature, salinity, turbidity, solar radiation, and currents to map wastewater and seawater distribution, providing critical insights into the bay's environmental dynamics.
