Hydrochemical and atmochemical mercury dispersion zones over hydrothermal vents of the submarine Piip Volcano in the Bering Sea

Signs of mercury input and dispersion in the water mass and the atmosphere over the submarine Piip Volcano have been revealed. The mercury from hydrothermal vents has been found to release mostly as a component of hydrothermal-gas bubbles rising through the water mass to the sea’s surface. The mercury’s dispersion and the seawater’s enrichment with it is a consequence of the partial dissolution of the gas bubbles. The atmochemical dispersion zone is represented by an area of higher mercury concentration with two maximums shifted in the direction of the wind (northeastward) from the northern and southern peak of the volcano.
