A phytosociological survey of the Barents Sea coastal plant communities according to Braun-Blan­quet approach is presented. Ass. Honckenyo diffusae—Elymetum arenarii (Regel 1928) R. Tx. 1966. is des­cribed on the sand beach. Halophillous vegetation is fragmented and ascribed to the community type Stellaria humifusa—Triglochin palustre. Tall herb mea­dows on the shore are described as ass. Tripleuro­spermo—Festucetum arenariae ass. nov. Mesic and moist meadows on the sea-exposed slopes are described as ass. Polygono vivipari—Thalictretum alpini (Kalliola 1939) stat. nov. Ass. Geranietum sylvatici Nordh.1943 includes meadows along springs and brooks, ass. Rumici—Salicetum lapponi Dahl 1957 combines mea­dows with willow shrub layer. Heath vegetation of the marine terrains and low hills is presented by ass. Arctostaphylo alpinae—Empetretum hermaphroditi (Zinserling 1935) Koroleva 1994, and heathlands on the hilltops belong to the Loiseleurio—Diapensietum (Fries 1913) Nordh. 1943 subass. typicum и salicetosum nummulariae subass. nov. Stands of ass. Phyllodoco—Vaccinietum myrtilli Nordh. (1928) 1943 are common in the snow-protected habitats. Snow-bed communities are described as ass. Veratro lobeliani—Salicetum herbaceae ass. nov. Paludified heathlands are described as ass. Rubo chamaemori—Caricetum rariflorae (Regel 1923) stat. nov. Sloping fens belong to ass. Drepa­noclado revolventis—Trichophoretum cespitosi Nordh. 1928. The syntaxa spectrum of the area investigated shows close affinities to the low arctic tundra subzone as well as to the coastal vegetation of the subarctic region.

The Rybachiy and Sredniy peninsulas are situated at the 69th latitude and bounded by the Barents Sea. Their territories belong to the subarctic tundra. Coastal vegetation is the case of the azonal one, which is regularly disturbed by sea. The aim of the study is to find out the coastal plant communities diversity and investigate ecological and floristic features of the vegetation types. The classification, based on 99 original relevés using TWINSPAN algorithm and following analytical revision, was carried out with Braun-Blanquet approach. The plant communities were classified into 5 associations and one community type. These syntaxa belong to 4 alliances, 4 orders, and 3 classes (Cakiletea maritimae R. Tüxen et Preising in R. Tüxen 1950, Honckenyo peploidis–Leymetea arenarii R. Tüxen 1966, Juncetea maritimi Br.-Bl. in Br.-Bl., Roussine et Negre 1952). There is a special change in coastal vegetation while moving away from sea. Therefore, it is a case of local zonality. The halo-nitrophilous communities of ass. Atriplicetum lapponicae on sandy and shingle wash margins with seaweed debris are common for the low-level beaches. Further from sea they are changing by communities of all. Mertensio maritimae–Honcke­nyion diffusae. The sea influence gradually decrea­ses, but amount of seaweed debris is still high on the coastal sand dunes that is a common place for ass. Honckenyo diffusae–Leymetum arenarii. The communities of Ligusticum scoticum–Festuca rubra com. type cover the higher-level beaches. The nitrophilous species are common for low-level beaches but they are almost absent in high-level phytocoenoses which are considered being an intermediate stage between monodominant seashore grasslands of ass. Honckenyo diffusae–Leymetum arenarii and multispecies high-level seashore meadows (Koroleva et al., 2011). The Rybachiy and Sredniy peninsulas coastal ve­getation seems to be common with another arctic/subarctic areas but having more similarities with western coasts. Communities of ass. Atriplicetum lapponicae have not been marked for Murmansk region, and probab­ly do not occur to the east of the peninsulas (Koroleva, 2006; Koroleva et al., 2011; Matveyeva, Lavrinenko, 2011). However, they are common in western areas (Northern Norway and apparently Iceland) (Tüxen, 1970; Thannheiser, 1974). Silty and sandy low-level salt marshes belong to ass. Puccinellietum phryganodis. Ass. Puccinellietum coarctatae (syn. Puccinellietum retroflexae Nordh. 1954) communities are found on the shingle low and middle level salt mar­shes. The further decreasing of salt seawater influence results in ass. Junco gerardii–Caricetum glareosae community formation. They occupy middle and high level of salt marshes. Communities of associations Puccinellietum phryganodis and Puccinellietum coarctatae on low and middle salt marsh levels are widespread in arctic and subarctic zones (Thannheiser, 1974; Koroleva et al., 2011; Matveyeva, Lavrinenko, 2011). There is an interesting notice that communities of widespread ass. Caricetum subspathaceae were not found on the studied area. The diagnostic species of this association – Carex subspathacea – vegetated only in Junco gerardii–Caricetum glareosae communities. The reason of such phenomenon could be a small area occupied by salt marsh communities on the Rybachiy and Sredniy peninsulas, which turns out that all vegetation types cannot completely evolve.

The paper presents data from grain size and mineralogical analyzes of surface bottom sediment samples obtained on several cruises of the R/V Akademik Mstislav Keldysh (2016–2018) from different parts of the Barents Sea. Pebble and gravel material is found in surface sediments in the form of impurities scattered throughout the sea. Such a chaotic distribution pattern is apparently associated with ice separation. Coarse material is most common in the Barents Sea off the coast of the Kola Peninsula, off the coast of Novaya Zemlya, Spitsbergen, where it accumulates due to coastal abrasion. In addition, a fraction >1 mm is widespread at depths where fine fractions are stirred and leached. The most common sediments in coastal shallow water are sands. Sands (0.1–1 mm) are widespread in the southern and southeastern regions of the sea, in the region of the Pechora polygon, the Kaninsky shallow water, the Kola Peninsula, and in the northwest, off the coast of Svalbard. With increasing depth, the sands are replaced by mixed sediments with a low admixture of pelite. Pelitic sediments are prevalent in the central part of the sea. Precipitation with a pelitic fraction (<0.01 mm) of more than 50% occupy about 70% of the Barents Sea. They are widespread in deep-sea hollows and trenches, as well as in the numerous fiords of the North Island of Novaya Zemlya and Franz Josef Land. Surface sediments have a predominantly terrigenous composition; only at the border with the Norwegian Sea the proportion of biogenic material increases. The mineral composition of sediments is dominated by quartz and feldspars, clay minerals are mainly represented by illite, smectite and kaolinite.

The plant communities with Arenaria pseudofrigida are common on the cobble-loam grounds on the edges of marine terraces on the Vaigach, Dolgiy and few smaller islands in the south-eastern part of the Barents Sea. These communities influenced by sea salty spray are described within 4 new synataxa (2 associations and 2 subassociations). They are provisionally placed within the alliance Arenarion norvegicae Nordh. 1935. order Thlaspietalia rotundifolii Br.-Bl. in Br.-Bl. et Jenny 1926, class Thlaspietea rotundifolii Br.-Bl. 1948.

The article studies the dynamics of overgrowth of saline marches of tidal estuaries of the Whit. Changes in the coastal vegetation depend on the salinity of the water and soil, the magnitude of the tides and the degree of flooding of the coastal strip, the relief and the mechanical composition of the coastal soils. Given the environmental series of overgrowing marches under conditions differing in the magnitude of the tides at the estuary of rivers. It is shown that the halophytic vegetation and its communities occupy the largest areas in the macrotidal conditions of the estuaries of the Chizha and Chesha rivers of the Kanin Peninsula, where marching coast reach 10–20 km from the coastline of the sea at the mouths of rivers. The dynamics of coastal communities depending on water salinity is studied. Communities dominated by obligate halophytes tend to strongly saline ecotopes of marches located on the maritime boundary of estuaries filled with water salinity of more than 20‰, in the zone of constant salinization of estuaries, communities of facultative halophytes and tolerant species more often occupy medium and slightly saline marches in the tops of estuaries.

Holocene Period

A lot of work has been devoted to the study of the coastal zone of the southern coast of the Barents Sea. However, they are mainly devoted to the period of deglaciation of the territory and the subsequent marine transgressions. The Holocene period was less interesting for researchers, because it was believed that the coast was stabilizing by this time and almost no significant changes were taking place. In recent years, interest in the dynamics of the coastal zone of the last millennia is mainly associated with the problem of climate change and the melting of Arctic ice in the modern period. In this regard, the study of new sequences of the coastal zone of the Barents Sea is especially relevant. Recently, new studies of the Holocene history of the coastline of the northwestern coast of the Kola Peninsula have appeared, which change some prevailing ideas about the dynamics of the coastline in the Holocene period. The presented review is caused by the need to summarize new results and existing ideas.

Specimens of the rare species Cynodontium suecicum (Rhabdoweisiaceae, Bryophyta) were collected near Drozdovka Bay on the Barents Sea coast of the Kola Peninsula (Russia) in 2016. They were compared with samples of C. suecicum from the Teriberka area (also the coast of the Barents Sea) gathered in 1977 by R. N. Schljakov. The morphological features of both groups of samples were studied, and nucleotide sequence data for ITS1-2 nrDNA and trnL-F cpDNA were obtained. Molecular analysis suggested C. suecicum as a hybrid that inherited cytoplasmic DNA from C. tenellum and nuclear DNA from Kiaeria blyttii. Taking into account the rather clear morphological delimitation against other species, combined with the stability of genetic characters, we believe that S. suecicum should be retained as a species-level taxon.
