Holocene Paleoenvironmental Implications of Diatom, Non-Pollen Palynomorph, and Organic Carbon Records from the Kandalaksha Bay of the White Sea (European Arctic)

Variations in sea surface conditions and level through the Holocene Kandalaksha Bay, White Sea, were reconstructed based on study of core sediments from outer using modern analog technique applied to dinocysts addition diatoms, TOC, δ13Corg, CaCO3, grain size data. The chronostratigraphy was defined accelerator mass spectrometry 14C dates mollusk shells. results indicated an increase water depth Bay central Dvina until late Holocene. From about 9.5 7.5 cal kyr BP, data suggested a general trend increasing temperatures (up 14 °C), at least areas with inflow Atlantic waters. last 2.5 characterized by increased freshwater runoff Sea.
