Phytoplankton Community Structure in the Polar Front of the Eastern Barents Sea at the End of the Growth Season     

V. M. Sergeeva  L. S. Zhitina  S. A. Mosharov  A. A. Nedospasov  A. A. Polukhin 《Oceanology》2018,58(5):700-709

Phytoplankton community and its distribution were investigated in the south part of the Polar Front in the eastern Barents Sea in October 2014. Analysis of the spatial differences in the phytoplankton structure was performed in connection with changes of the temperature, salinity and biogenic regime. At the end of the growing season in the phytoplankton community was dominated by destruction processes and the concentration of nutrients in the upper mixed layer was higher than the limiting level. Coccolithophores (Emiliania huxleyi and Discosphaera cf. tubifer) dominanted over investigated area. The maximum values of abundance and biomass of coccolithophores reached 90.4 mln.cell/m³ and 30.8 mgC/m³, drawing up 82% of the total number and 93% of the total biomass of phytoplankton. Influence of transformed the waters of Atlantic origin was observed in the western part of the investigated area. The number of species in the phytoplankton community here was 1.5–2 times lower than in the eastern part of the occupied mostly by Barents Sea water. In the eastern part of the presence of large dinoflagellates Neoceratium spp. (Ceratium spp.) and Dinophysis spp., lower values of chlorophyll a concentration, a higher proportion of pheophytin in the amount of pigment chlorophyll + pheophytin, the high content of ammonia in the upper mixed layer showed that in this area the phytoplankton was at a later seasonal succession stage than the western part.  相似文献   

Colorful Planets,Cometary Tail,and Nuclear Winter     

A.?S.?GinzburgEmail author 《Izvestiya Atmospheric and Oceanic Physics》2018,54(3):265-274

After the 1967 flight of the Venera-4 automatic interplanetary station (AIS), the study of planetary atmospheres became one of the key areas of scientific research at the Institute of Atmospheric Physics (IAPh), USSR Academy of Sciences. The goal of the Venera-4 mission was to deliver a descent vehicle into the atmosphere of Venus and study the physical parameters and chemical composition of the atmosphere. IAPh scientists published several articles on the analysis of these measurements, with A.M. Obukhov himself directly involved in writing some of these articles. An analysis of the properties of the Martian surface and atmosphere from the data of the Mars-2, Mars-3, and Mariner-9 missions in November–December 1971 set the stage for a series of studies on the atmospheric effects of Martian dust storms. Based on the study of the atmospheres of terrestrial planets, IAPh scientists developed a simple model for the nuclear winter phenomenon, i.e., a long-term cooling due to massive fires caused by nuclear explosions. Obukhov took a keen interest in this subject and participated in the publication of review articles on the possible atmospheric and climatic effects of a nuclear war. In another publication, Obukhov and his coauthors provided a theoretical analysis of the possible causes for the tail from Halley’s comet ripping off, as was observed in January 1986. The present article gives a brief overview of the IAPh works on Solar System research and on the possible consequences of a nuclear conflict, which were published in the 1960s–1980s while Obukhov was alive.  相似文献   

Geodynamic Settings of the Formation of Microcontinents,Submerged Plateaus,and Nonvolcanic Islands within Continental Margins     

E.?P.?DubininEmail author 《Oceanology》2018,58(3):435-446

During breakup of the continental lithosphere, partial or complete separation of small continental blocks from the mainland frequently occurs, leading to the formation of microcontinents or partially separated submerged plateaus that advance toward the ocean, as well as to emergent nonvolcanic islands. The article reviews the geodynamic settings in which isolated blocks of continental crust can form. Depending on the thermomechanical conditions of continental rifting, such blocks may be preserved as emergent islands or as submerged blocks of continental crust.  相似文献
