Description

Geological Survey of Finland, Special Paper 45. 2007. - 70 pages, 48 figures, 14 tables andone appendix.Отчёт по результатам выполнения совместного (Финляндия - Россия) проекта в области осадконакопления и геохимии осадков в Восточном заливе Финляндии (Балтийское море), а также связанными с ними угрозами и опасностями естественного и техногенного характера.Первоисточник: www.gtk.fiThe joint Finnish-Russian project Sediment geochemistry and natural and anthropogenic hazards in the marine environment of the Gulf of Finland (SAMAGOL) aimed at filling a gap in knowledge of the environmental situation of the seafloor in the Eastern Gulf of Finland. This publication contains five peer-reviewed papers based partly on old existing data combined with new data collected during the time-frame of the SAMAGOL project. The Quaternary deposits of the seafloor of the Eastern Gulf of Finland are described in the paper by Spiridonov et al. based on numerousdata concerning the structure, distribution, and lithology of the sediments. Also problems of correlation with Quaternary deposits on land are discussed.Contents: The Quaternary deposits of the Eastern Gulf of FinlandThe influence of ferromanganese concretions-forming processes in the Eastern Gulf of Finlandon the marine environmentDistribution of heavy metals and arsenic in soft surface sediments of the coastal area off Kotka,North-Eastern Gulf of Finland, Baltic SeaSeafloor anoxia and modern laminated sediments in coastal basins of the Eastern Gulf of Finland,Baltic SeaBackground concentrations of trace metals in modern muddy clays of Eastern Gulf of Finland,Baltic Sea
