The first data were obtained on the vertical chlorin flux in the water column and its accumulation in the upper layer of sediments of the Caspian Sea. Seasonal variability of the chlorine concentration in sedimentary matter was evaluated. The tendency of decrease in the phytoplankton-synthesized (allochtonous) organic matter content was revealed over approximately the past 60 years. 相似文献

The first data on the chemical composition of dispersed matter from sedimentary traps are reported. The suspended components of sedimentary matter (amorphous silica, organic matter, carbonates, and lithogenic material, as well as Fe, Mn, and minor elements) are considered. As a result, it is shown that the intraannual variability in vertical fluxes of sedimentary matter is characterized by a seasonal increase in spring and autumn. The high fluxes of the components of sedimentary matter on the northern and southern slopes of the Derbent Basin in winter are explained by precipitation of material from the nepheloid layer that forms over the contour current. 相似文献

Diatom algae, aquatic palynomorphs, and the grain-size of surface sediments from bays of the White Sea were investigated in a program dedicated to the study of marginal filters (MF) in the Severnaya Dvina, Onega, and Kem rivers. Three microalgal assemblages are established in surface sediments, which replace each other successively with distance from river mouths and are characterized by a gradual decrease in a share of freshwater species of diatoms and Chlorophyceae algae, significantly varying concentrations of marine diatoms and dinocysts due to changes in water salinity, grain-size composition of sediments, quantitative distribution of suspended particulate matter (SPM), and water productivity at different marginal filter stages. 相似文献

The first data on the concentrations, fluxes, and mineral and chemical compositions of aerosols from the near-water surface layer of the Caspian Sea are presented. It is shown that the aerosol fluxes onto the sea surface are comparable to the fluxes of a lithogenic substance in a water column. The mineral and chemical compositions of aerosols depend on the carrying air masses that pass through different regions. The coefficients of enrichment of aerosols with chemical elements relative to the upper lithosphere and their correlation relationships are studied.

Résumé Dans l'article est examinée la question de l'analogie du niveau moyen mensuel de la mer pour un nombre de stations marégraphiques sur les côtes italiennes ct françaises de la Méditerranean. On peut constater que la variation de la quantité de l'eau dans la mer est le facteur principal à ce rapport, mais qu'on doit aussi tenir compte de la distance reciproque entre les stations, de l'influence de la force de Coriolis et de l'effet des éléments météorologiques.
Summary In the paper it is studied the question of the analogy between the average monthly sea-levels for a few tide gauge stations on the Italian and French coasts of the Mediterranean. It could be established that the variation of the water amount in the sea is the principal factor in this regard, but that the distance between the stations, the influence of the Coriolis force and the effect of meteorological elements must be considered, too.相似文献
