39 проб донных песчаных отложений, отобранных в восточной части Калининградского залива. На основании гранулометрического анализа составлена схема распределения песков. Показано, что они распространены вдоль берегов залива до глубин 2,5-3,0 м. В основном они представлены средними и мелкими песками. Наиболее распространенными песками являются мелкие...

The results of studying the concentration and composition of aerosol particles washed out by rainfalls in the coastal zone of the southeastern Baltic Sea are presented. Investigations were carried out in 2008–2015. It is shown that aerosol material is represented by mineral, biogenic, and anthropogenic particles, and its average concentration in ra...
Article
The main objective of this study was to compare conditions for sedimentation in a lagoon in the presence and absence of ice coverage. The winter conditions of Vistula Lagoon (hydrology, suspended solids in water, ice, and snow) were studied during the period 2011–2016. Three-dimensional numerical modelling was used to simulate the water level varia...

The Curonian and Vistula Lagoons should be considered to be a part of one natural hydraulic system, as they are connected via two branches of the Prgolya River (the Pregolya River proper and the Deyma branch). The catchment upstream of the point of bifurcation of the Pregolya River into these two branches belongs to both lagoons and comprises 14 %...

Vistula Lagoon is the second largest lagoon in the Baltic Sea with maximum depth 5.2 m and average depth 2.7 m. Water volume and area are 2.3 km3 and 838 km2. Lagoon is connected with the Baltic Sea by single inlet 400 m wide and 10-12 m deep. Sediment budget estimation were made using literature sources, results of field measurements (hydrology, s...

Field data, collected by the authors during winter expedition studies in Kaliningrad Bay, are analyzed. Notwithstanding the presence of ice cover, considerable advective processes are shown to be taking place in the bay. Seawater enters the bay, spreading in the bottom horizon all over the water area. Suspended sediment concentration in under-ice p...

The article discusses the possibility of protecting the shore by disposing of dredged material at shallow depths. An example of a permanently eroded open marine shore segment located south of the Vistula Lagoon inlet (south-eastern part of the Baltic Sea) is considered. This shore segment is permanently caused by downstream erosion due to the moles...
Article
Described is the horizontally oriented bathometer with the piston mechanism of water sucking that enables taking water samples from the thin (up to 10 cm) layer (including the bottom layer) avoiding the spread of bottom sediments.
Article
Представлены результаты литологических и гидрологических исследований, выполненных в акваториях малых гаваней Калининградского залива. На основе изучения вещественного и гранулометрического состава донных отложений, солености, температуры и прозрачности воды были выявлены особенности условий, в которых происходит осаждение, накопление или транзит о...
Article
Full-text available
The results of studies of particulate matter in a navigable channel are given. For the first time, field data on suspension concentration were collected immediately after the passage of ships with different drafts. The concentration of suspended matter is shown to depend on the draft of the passing ship and the type of soils on the bed of the canal...
Article
By the data of cruise 54 of the R/V Akademik Mstislav Keldysh (September 2007), the results of geochemical studies of the redox processes in the bottom sediments of the Ob River's near-mouth area as applied to the redox indicator elements such as manganese, iron, and sulfur are presented. The characteristics of the bottom sediments and the distribu...
Patent
Устройство относится к области исследования донных отложений (грунтов) в мелководных бассейнах (реках, озерах, береговой зоне моря) с целью проведения последующих физико-механических, химических и других видов анализов, и может быть использована в морской геологии, литологии, седиментологии, геоэкологии. Колонковый пробоотборник штанговый состоит и...
Data
According to data from Cruise 54 of R/V Akademik Mstislav Keldysh (September 2007) results of geochemical studies of redox processes in bottom sediments from the Ob River mouth area as applied to redox indicator elements (such as manganese, iron, and sulfur) are presented. Parameters of bottom sediments and distribution of these elements evidence n...
Article
In this paper, a functional scheme and basic principles of the floating aerosol trap, which has been developed by the authors, are presented. The first experimental results of the vertical aerosol fluxes coming on the Visla Bay surface (the Baltic Sea) and measured with the trap are demonstrated.
Article
The results of multidisciplinary field studies of a segment of the coastal zone (in the area near the Baltiysk Strait South-East Baltic) are presented. The natural regime of the evolution of this zone has changed under the effect of anthropogenic factor. Bed topography, bottom sediments, and shore morphology and dynamics are characterized. The effe...
Conference Paper
В данной работе впервые рассматриваются результаты натурного определения скорости осаждения взвеси, взмученной проходящим судном при его прохождении по навигационному каналу. Применена экспоненциальная аппроксимация изменения концентрации взвеси со временем. Для участков, покрытых мелкозернистым песком (песок пылеватый) и илистым осадком время сниж...

Article
The distribution of suspension, its composition, and particle size characteristics are studied in Kaliningrad Bay. Zoning of the bay according to the water turbidity is made. The main factors controlling the formation and space and time variations in the suspended matter are determined.
Article
Terrigenous clastic sediments with a biogenic component are predominant types in Russian part of the Vistula Lagoon of the Baltic Sea. The following types of sediments are recognized: pebble-gravel, sand, and coarse aleurite, fine aleuritic mud and aleuro-pelitic mud. The most abundant among them are fine aleuritic mud, which cover about 45% of the...
