Аннотация: In meromictic lakes such as Lake Shira, horizontal inhomogeneity is small in comparison with vertical gradients. To determine the vertical distribution of temperature, salinity, and density of water in a deep zone of a Lake Shira, or other saline lakes, a one-dimensional (in vertical direction) mathematical model is presented. A special feature of this model is that it takes into account the process of ice formation. The model of ice formation is based on the one-phase Stefan problem with the linear temperature distribution in the solid phase. A convective mixed layer is formed under an ice cover due to salt extraction in the ice formation process. To obtain analytical solutions for the vertical distribution of temperature, salinity, and density of water, we use a scheme of vertical structure in the form of several layers. In spring, the ice melts as top and bottom. These processes are taken into account in the model. The calculated profiles of salinity and temperature of Shira Lake are in good agreement with field measurement data for each season. Additionally, we focussed on the redox zone, which is the zone in which the aerobic layers of a water column meet the anaerobic ones. Hyperactivity of plankton communities is observed in this zone in lakes with hydrogen sulphide monimolimnion, and Lake Shira is among them. The location of the redox zone in the lake, which is estimated from field measurements, coincides with a sharp increase in density (the pycnocline) during autumn and winter. During spring and summer, the redox zone is deeper than the pycnocline. The location of pycnocline calculated with the hydro physical model is in good agreement with field measurement data.

Аннотация: Seasonal dynamics of phytopigment concentrations in the ocean is one of the key factors indicating the types and intensity of hydrobiological exchange processes in the ocean surface layer. Thanks to the efficient operation of the SeaWiFS equipment for the last 7 years we have managed to carry out statistical analysis of image time series, which is necessary for estimation of reliability of investigations of oscillatory hydrobiological processes on a global scale. Using the autocorrelation method, we revealed a pronounced heterogeneity of the types of seasonal dynamics in the ocean. Statistically significant seasonal dynamics of phytopigment concentrations exists only at 19% of the area of the Global Ocean. On 51% of the area seasonal dynamics is disturbed essentially so, that becomes statistically insignificant and is absent at 30%. The most interesting feature of the pattern obtained was the diversity of the seasonal dynamics of chlorophyll concentration under similar climatic conditions. Another interesting feature of such data presentation is that two types of seasonal dynamics - yearly and half-yearly - were defined. The detected zonality will provide the basis for more efficient development and application of ecological modeling, taking into account real-life hydrobiological and hydrological conditions.

Аннотация: The work presents the data on the spatial distribution of temperature anomalies in the Global Ocean, based on the long-term measurements with the AVHRR satellite equipment. It is noteworthy that such results can be only obtained by using long time series of satellite images. To obtain them by ship-borne methods is actually impossible. The proposed anomaly criterion is equal to a difference between minimum/maximum and average temperature, normed for the mean square deviation. The difference is calculated from the whole time series (with regard to a season). Based on this criterion, anomalies can be distinguished on the background of usual seasonal dynamics at various absolute values of deviations of the measured parameter. Besides, rare, single, fluctuations can be also revealed. Based on the proposed criterion, connected zones have been defined. These zones occur almost in every part of the Global Ocean. The data obtained have been analyzed in association with the CZCS (1978-1986) and SeaWiFS satellite images in order to compare them with the areas of anomalous dynamics of chlorophyll concentration and the regions quasistationary in the seasonal dynamics of chlorophyll. Anomalies in the temperature dynamics are of exceptional importance for the formation of climatic deviations; they affect the ocean-atmosphere interaction and reflect variations in the hydrological structure of the surface waters. The work presents a comparison with the dynamics of chlorophyll concentration distribution determined from the SeaWiFS data for the Atlantic Ocean. В© 2003 COSPAR. Published by Elsevier Ltd.

Аннотация: The main task of complex environmental monitoring is evaluating the state of an aquatic system and state prediction of ecosystem links under different levels of water supply, anthropogenic influence and climatic fluctuations. The paper analyzes the inter-annual dynamics of functional activity of bacterio – and phytoplankton of the Krasnoyarsk reservoir depending on abiotic factors (reservoir filling level and temperature conditions). The data have been obtained from series of regular observations during the growing season in the 2000 – 2017. In the work, distribution of concentration of chlorophyll "a" and photosynthetic activity of the phytoplankton, production characteristics of bacterioplankton and biochemical oxygen demand (BOD5) are presented. The analysis is carried out in the model-driven system of support of hydrobiological studies of the Krasnoyarsk reservoir by the method of k-means. Systematization of accumulated data of scientific research has become a basis for a sequence of long-term investigations, a comparative analysis of data from related studies and data analysis.

Аннотация: Сформулировано новое направление, связанное с наличием в водоемах внутренних активных дисперсных границ раздела фаз и оценкой их роли в формировании функциональной структуры экосистем. Разработаны методы изучения функциональной структуры водных экосистем на основе оценки граничных поверхностей раздела фаз различных компонентов взвешенного вещества. На их основе изучено общее содержание взвешенного вещества, степень его дисперсности (количество частиц, их размеры), содержание растворенного органического вещества (РОВ), доля адсорбированного ОВ (АОВ), площади граничной поверхности минеральной и биотической взвесей, обусловленной наличием фаз pаздела взвесь- вода для основных взвешенных компонентов озера Ханка. В частности, структуру экосистемы озера (в летний сезон), выраженную отношением граничных поверхностей дисперсных компонентов, для ряда зоопланктон - простейшие - фитопланктон - бактерии - органический детрит - органо-минеральный детрит (ОМД) можно представить соотношением 1:1:10:30:60:1400. Полевые исследования дополнены лабораторными экспериментами по выявлению роли минерального взвешенного вещества в функционировании экосистем. Большая величина поверхности минеральной взвеси ($100\div200 м. /м. $), значительное количество АОВ (60-90%) и прикрепленной бактериальной микрофлоры (около 40%) определяет активную минерализацию органики через поверхностные взаимодействия. Из этого следует более высокая продуктивность фитопланктона и последующих звеньев пищевой цепи, что играет значительную pоль в функциониpовании экосистемы лессовых водоемов, pегулиpуя потоки трансфоpмации веществ и их концентpаций в сpеде чеpез pазветвленную гpаничную повеpхность. Предложена схема трофометаболических связей планктонного сообщества с включением органо-минерального детрита как важного функционального звена. Оценены адсорбция (прикрепление) бактерий на ОМД в зависимости от массы адсорбированного органического вещества и численности бактериопланктона, а также активность прикрепленного (и агрегированного) бактериопланктона по сравнению со "свободно живущим" в толще воды. Выявлена зависимость удельной первичной продукции от удельной площади поверхности клеток водорослей (S/V) и показана связь S/V с сапробностью водной среды для озера. На основе экспериментальных данных по светорассеянию вод озера Ханка и модельных сред теоретически в приближении Релея-Ганса-Дебая выяснена структура хориона (минеральное ядро+органическая оболочка). Показано влияние минеральной взвеси на активность биохимических процессов, снижение токсичности среды и повышение выживаемости водных организмов.
The new lead of investigation related to the presence in water bodies of internal active phase boundaries and their role to forming of the ecosystems functional structure has been enunciated. The methods for studying the functional structure of the water ecosystems, on the basis of investigating phase boundary areas, were developed. On the basis of this methods the common content of suspended matter, number of suspended particles, its sizies, the content of dissolved organic matter (DOM), part of adsorbed DOM (AOM), the areas of dispersed phase boundaries for mineral and biotic suspended matter were investigated in waters of Khanka lake. The spatial dispersed structure of lake ecosystem attributed with the suspended matter-water phases boundary for main suspended components has been studyed. In particular case the ecosystem structure (in summer season) pronounced with ratio dispersed boundary surfases for sequence zooplankton - protozoa - phytoplankton - bacteria - organic detritus - organo-mineral detritus is 1:1:10:30:60:1400. The field researches are supplemented by laboratory experiments on detection of a role of mineral suspended matter in ecosystems functioning. The great size of surfase of mineral suspended matter ($100\div200 m. /m. ), high amount of DOM adsorbed on huge surface (60-90%) and adsorbed bacterioplankton (about 40%) supposes the active mineralization of DOM by attached microorganisms through the intermediary of surface coupling. Hence more high productivity of the phytoplankton and the subsequent links of the food chain follows play the great part in ecosystem functioning of loess water bodies regulating fluxes of substances transformation and its concentrations in a medium through the intermediary of ramified boundary surface. The scheme of trophometabolic bonding of the planktonic community with incorporating of organo-mineral detritus as important functional link was proposed. The adsorption of bacteria to organo-mineral detritus is appreciated in dependence from mass of adsorbed organic matter and of bacterioplankton numbers. The activity of attached (and aggregated) bacterioplankton is evaluated on a comparison with " freely living " in water mass. Connection of a specific primary production with specific area of algae cells surface (S/V) and connection S/V with saprobity of a water medium are shown. Theoretically in Rayleigh-Gans-Debye approximation on the basis the experimental data on a scattering of light of Khanka lake waters and model mediums the chorion structure (mineral core + organic envelope) on level of separate particle is clarified. The influence of mineral suspended matter for the decrease of toxicity of a medium and for the increase of the survival of water organisms is appreciated.

Аннотация: The estimation of the influence of climatic factors on the concentration of particulate matter in the surface layer of the atmosphere of the villages of Drokino and Minino was carried out using the CityAir air monitoring station. It is shown that the concentration of PM2,5 increases with increasing atmospheric pressure and lowering the temperature of the air environment. These dependencies are approximated by linear functions (R2 ? 0,8). It has been established that concentration PM2,5 exceeds 2,8-4,2 times of the hygienic standard established for the atmosphere of populated areas during periods of anticyclone. With a wind speed of more than 4 m/s, the PM2,5 concentration in the atmospheric surface layer of the villages is lower than the values of daily average concentration. © 2019 SPIE.
