Conclusions,hemically important element. The comparison of two independent evaluations of the masses of deposited Fe at the bottom in a year (direct measurements of the vertical fluxes in the sea with the help of sedimentary traps and summing of Fe entering to the sea from different sources) demonstrated the co

High chlorophyll a content, exceeding 1 μg/l, was observed throughout most of the sea. The obtained results indicate that the White Sea can be regarded as having eutrophic water.
