The hydrographic system is characterized by uniform currents due to the continental runoff, concentrated in the upstream part of the bays. There is a general cyclonic circulation in the sea, homogenizing the water masses. The surface water temperatures in the White Sea range from +7 to +15 ☌ in summer and fall down to a freezing point below −1.6 ☌ in winter. They are characterized by a consistently high salinity of 34–35 psu and a relatively high temperature ( Figure 2a,b) as compared with other Arctic seas. Water masses entering the White Sea from the Barents Sea have an Atlantic origin. We used the modern analog technique for the reconstruction of the salinity, temperature, and duration of the sea ice cover.

Our interpretations of fossil assemblages of diatoms and NPP in core sediments were based primarily on the previously established patterns of their distribution in the surface sediments and their relationship with hydrological and sedimentation processes. Diatoms dominate in the phytoplankton communities, and dinoflagellates are very important components of the White Sea ecosystem. Diatom and non-pollen palynomorph (NPP) assemblages are among the most useful micropaleontological groups for paleoenvironmental reconstructions in the White Sea region. These included micropaleontological tracers (diatoms and dinocysts), in addition to lithological and geochemical properties (grain size, CaCO 3 and organic carbon concentration, and δ 13C of organic carbon) of the sediment. Our aim was to reconstruct the sea surface salinity and temperature, seasonal sea ice cover, and other environmental parameters based on multiproxy records. The core PS-6066 was collected in the Kandalaksha Bay, the deepest estuary in the White Sea that reaches a maximum water depth of 343 m.

Here we present new paleoenvironmental data based on the analyses of the sediment core PS-6066, in which an age model based on new AMS 14C dates was defined.
