Заглавие : Trends of chlorophyll concentration in the surface layer of the Northern and Central Atlantic, a satellite data-based study
Место публикации : Advances in Space Research. - 2002. - Vol. 30, Is. 11. - С. 2535-2540. - ISSN 02731177 (ISSN) , DOI 10.1016/S0273-1177(02)80332-5

Аннотация: The new data on anomalies in seasonal dynamics of chlorophyll concentration in the ocean have altered the approach to the analysis of long-term trends of phytopigments in the surface layer of the ocean. Zones have been found in which at various times there was a many-fold increase in chlorophyll concentration versus its usual level. These changes are local in time and space. If anomalies in the long-term tendencies in the change of phytopigment surface distribution in the ocean are ignored in the analysis, the resulting picture will inadequately reflect the real processes. The work presents the results of the analysis of long-term trends of chlorophyll concentration on the basis of the CZCS satellite data in the Atlantic Ocean. The results are given as maps representing different variants of trends. The data obtained can be used to analyze the consequences of long-term changes of climate and changes in the interaction between the atmosphere and the ocean. В©2002 COSPAR.

Заглавие : Spatial and temporal anomalies of sea surface temperature in global scale (by space-based data)
Место публикации : Advances in Space Research. - 2004. - Vol. 33, Is. 7. - С. 1179-1183. - ISSN 02731177 (ISSN) , DOI 10.1016/S0273-1177(03)00369-7
Ключевые слова (''Своб.индексиров.''): anomalies--chlorophyll--hydrological structure--space-based data--temperature--chlorophyll--data reduction--oceanography--satellites--surface properties--temperature measurement--satellite images--spatial distribution--space research--avhrr--chlorophyll--remote sensing--satellite imagery--sea surface temperature
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 work presents long-standing CZCS-satellite-based data about spatial distribution of anomalies in chlorophyll concentration and temperature of the ocean. An anomaly criterion is proposed. Maps of Atlantic ocean areas with elevated probability of anomalies are given. Properties of anomalous zones in different parts of the Atlantic ocean are discussed. Satellite-based maps of anomaly coefficients for chlorophyll concentration and temperature in the Atlantic ocean have been shown to feature substantial differences, the zones of elevated anomaly of chlorophyll concentration and temperature - to be close only in the vicinity of the Amazon outflow into the Atlantic ocean. Along with fundamental knowledge about dynamics of biological phenomena in the ocean the methods described may be used to reveal deviations due to anthropogenic impact. The methods presented may be used to process SeaWiFS prograna data. The data derived may be used to analyze long-standing time series to estimate randomness of cunent changes. В©2002 COSPAR.

Заглавие : Results of analysis of spatial and temporal long-term stability of quasistationary areas in the Atlantic Ocean based on multi-satellite measurements (CZCS and SeaWiFS data)
Место публикации : Advances in Space Research. - 2004. - Vol. 33, Is. 7. - С. 1184-1188. - ISSN 02731177 (ISSN) , DOI 10.1016/S0273-1177(03)00366-1

Аннотация: The paper analyzes the stability of areas in the Global Ocean, which are quasistationary with respect to the seasonal dynamics of chlorophyll concentration. Such areas were first discovered based on the CZCS data. They occur almost in all regions of the Global Ocean. They reflect typical seasonal dynamics of phytoplankton, which depends on both large ocean currents and local hydrological instability. It is related to the displacement of frontal zones and to local hydrological anomalies. Since the completion of the CZCS work there has been a 10 years gap in monitoring chlorophyll spatial distribution dynamics in the ocean. The reason is the long absence of equipment on the orbit, which would be suitable for the measurement of chlorophyll concentration. Recently, SeaWiFS data have been accumulated and their quantity is sufficient for the crude statistical analysis of image time series for 25 years. Thus, it has become possible to obtain data on the long-term stability of quasistationary areas and, therefore, on the stability of large-scale hydrological phenomena in the Atlantic Ocean.

Заглавие : Hidden staircase signal in recent climate dynamic
Место публикации : Asia Pac. J. Atmos. Sci. - 2015. - Vol. 51, Is. 4. - С. 323-330. - ISSN 19767633 (ISSN) , DOI 10.1007/s13143-015-0081-6
Ключевые слова (''Своб.индексиров.''): climate shifts--enso variability--pause in global warming
Аннотация: In this study we used HadCRUT4 monthly mean near surface temperature anomalies for 1950–2014 years in order to investigate properties of recent warming. Our aim was to separate changes produced by short-term natural variations and to look on temporal and spatial dynamics of residual temperature anomalies. For this we subtract linear influence of El Nino Southern Oscillation from each grid box of surface temperature measurements. We found that residual global temperature dynamics looks like staircase function: linear trends for three quasi-stable periods 1950–1987, 1988–1997 and 1998–2014 are near zero and near all warming occurred during two shifts of 1987/1988 and 1997/1998 years. Examples of similar staircase behavior of some climate parameters were found in NCEP/NCAR and NASA MERRA reanalysis data. Staircase signal suggests the existence of some regulation mechanism in climate system. This mechanism should maintain global temperature adjusted for El Nino Southern Oscillation near stable in 1950–1987, 1988–1997 and 1998–2014 periods nevertheless all the time growing forcing due to anthropogenic greenhouse gases. © 2015, Korean Meteorological Society and Springer Science+Business Media Dordrecht.

Ключевые слова (''Своб.индексиров.''): astrobiology--signatures of life--essence of life--multiformity of life
Аннотация: The question on the essence of life as phenomenon is the key one for astrobiology, since the answer to this question determines "breadth of our outlook". Taking Earth's version of life as the pattern extremely under-estimates our estimation of the probability of life origin and respectively expected probability of extraterrestrial life discovery. In the paper the hypothetical key attribute of life in general is selected on the base of comparative analyses and deductive inference. Simulation conducted on the base of neural network model shows that the same function could be realized by means of great variety of structures, which originated in the course of an evolutionary process. So multiplicity of evolutionary outcomes essentially increases the probability of final result - realization of an integrated function providing fitness to environment. Life as the integrated function can be realized via great variety of development ways and structures. A logical consequence of definitions for life as phenomenon is suggested. Final one is "Life is specific organization of informational and energetic processes coupling, enabling choice-making, and displayed as anomalies of different kinds". Anomalies of visible form, mechanical movement, chemical composition and noticeable response are considered. Presented in the paper sweeping generalization is not rigorously proven, however it can play heuristic role in increasing the level of specificity of searching for extraterrestrial life.

Заглавие : A study of the stationary and the anomalous in the ocean surface chlorophyll distribution by satellite data
Место публикации : International Journal of Remote Sensing. - 2004. - Vol. 25, Is. 7-8. - С. 1383-1387. - ISSN 01431161 (ISSN)
Ключевые слова (''Своб.индексиров.''): chlorophyll--data reduction--oceanography--planets--probability--satellite communication systems--biospheres--remote sensing--chlorophyll--concentration (composition)--remote sensing--satellite data--sea surface
Аннотация: Variability of chlorophyll concentration in the ocean is one of the most important components of the primary production process on the planet. To preserve the biosphere and to make appropriate use of it, it is imperative to have a deep insight into the long-term dynamics of the primary production on the planet. To investigate the dynamics of chlorophyll concentration based on satellite data, the Institute of Biophysics (Russian Academy of Sciences, Siberian Branch) has developed a geoinformation system. It was used to detect the areas in the global ocean that are quasistationary in relation to seasonal dynamics of chlorophyll concentration. Areas such as these, found in the Indian Ocean, are described in this work. These areas form the basis for the analysis of long-term dynamics of chlorophyll concentration. In these quasistationary zones systematic monitoring of phytopigment concentration is conducted by space-borne and marine craft. The work presents long-term satellite-based data on the space distribution of anomalous deviations of chlorophyll concentration in the ocean. An anomaly criterion is proposed and maps of Pacific Ocean areas with a high probability of anomalies are presented. В© 2004 Taylor and Francis Ltd.
