Vertical particle fluxes of sediment matter in the White Sea and western Arctic seas
No full textStudies of vertical particle fluxes were carried out in 2006-2007 in the Dalnezelenetskaya Inlet of the Barents Sea and in the Chupa Inlet of the White Sea. Average annual particle flux volume in the Dalnezelenetskaya Inlet was 20-21 cm**3/m**2/day, or 1350-1400 mg/m**2/day, while in the Chupa Inlet it was 17-18 cm**3/m**2/day, or 500-550 mg/m**2/day. Sediment matter is mostly represented by flocculent detritus less than 100 µm in size. Currently estimated sedimentation rate is 0.9-1.1 mm/a in the Dalnezelenetskaya Inlet and 0.3-1.0 mm/a in the Chupa Inlet

Get PDFAs a result of studies of newly fallen snow in the North of the Kola Peninsula, it was found that from January to May 2018 its density amounted, on the average, to 0.160±0.006 g/cm3 (n = 82), and pH of melted snow water - 6.87±0.14 (n = 47). Neutral and slightly alkaline reaction of snow water impedes the mobility of heavy metals in the insoluble fraction of aerosols. In loose fresh snow (density less than 0.2 g/cm3) the content of solid aerosols increases as the snow density grows. The average concentration of solid aerosol particles in freshly fallen snow is 4.04±0.24 mg/l (n = 47). Over the winter period of 2018 (120 days), about 1.85-2.37 thousand tons of aerosol substance precipitated on the underlying surface of the area under investigation. The daily deposition of aerosols averaged 1.03-1.33 mg m-2, and together with solid precipitation, mg m-2 day-1: Zn - 12.5-14.2, Cu - 2.2-2.5, Pb - 0.58-0.66, Cd - 0.31-0.42. According to the results of our researches, two impact areas were previously identified, both allocated to large regional centers. The Murmansk coast is divided into three background areas, each of which corresponds to its natural landscape complex

Abrasion and algal fouling of coarse material on the Murman littoral
No full textOn the Murmansk coast of the Barents Sea the boulder littoral zone is widely spread mostly covered by Fucus
communities. This is one of the most productive benthic communities of the Barents Sea. The studies of
intertidal communities have the long history, but the dynamics of intertidal ecosystems due to surf and storms is
not clear. The goal of the work is to identify the leading factors that determine the rate of abrasion of coarse
material and fouling algae-macrophytes of the intertidal zone of Murman. The study has been conducted in the
Zelenetskaya Bay of the Barents Sea on the basis of the biological station of the MMBI KSC RAS. The rate of
abrasion has been carried out during 2004–2013, phyto-overgrowing – 2009–2013. In three pilot landfills 12
samples of coarse material have been exposed during the year (from July to next July). The weight change of the
sample as well as species composition and biomass of algae of fouling communities have been investigated. The
influence of the surf intensity, temperature of water and air has been analyzed (univariate analysis of variance
ANOVA has been applied). It has been shown that on the littoral of the Murmansk coast the abrasion of coarse
material is determined primarily by the number of storms, so the storm rate has been proposed. It has been
revealed that the density of fouling boulders with macroalgae depends primarily on the intensity of the surf and
the average gradient of air temperature. The basis for the emerging communities of annual species are green
(Acrosiphonia arcta, Blidingia minima, Spongomorpha aeruginosa) and brown algae (Pylaiella littoralis,
Dictyosiphon chordaria). These algae groups are found everywhere in Fucus communities of the boulder
intertidal zone of the Murman coast and probably they are the intermediate stage of fouling the coarse-grained
materia
