Oil Pollution in the Black and Caspian Seas
Article Satellite Survey of Inner Seas: Oil Pollution in the Black and Caspian Seas Marina Mityagina and Olga Lavrova * Space Research Institute of Russian Academy of Sciences, Moscow 117997, Russia; [email protected] * Correspondence: [email protected]; Tel.: +7-495-333-4256 Academic Editors: Elijah Ramsey III, Ira Leifer, Bill Lehr, Xiaofeng Li and Prasad S. Thenkabail Received: 5 June 2016; Accepted: 17 October 2016; Published: 23 October 2016 Abstract: The paper discusses our studies of oil pollution in the Black and Caspian Seas. The research was based on a multi-sensor approach on satellite survey data. A combined analysis of oil film signatures in satellite synthetic aperture radar (SAR) and optical imagery was performed. Maps of oil spills detected in satellite imagery of the whole aquatic area of the Black Sea and the Middle and the Southern Caspian Sea are created. Areas of the heaviest pollution are outlined. It is shown that the main types of sea surface oil pollution are ship discharges and natural marine hydrocarbon seepages. For each type of pollution and each sea, regions of regular pollution occurrence were determined, polluted areas were estimated, and specific manifestation features were revealed. Long-term observations demonstrate that in recent years, illegal wastewater discharges into the Black Sea have become very common, which raises serious environmental issues. Manifestations of seabed hydrocarbon seepages were also detected in the Black Sea, primarily in its eastern part. The patterns of surface oil pollution of the Caspian Sea differ considerably from those observed in the Black Sea. They are largely determined by presence of big seabed oil and gas deposits. -
Tetrapod Localities from the Triassic of the SE of European Russia
Earth-Science Reviews 60 (2002) 1–66 www.elsevier.com/locate/earscirev Tetrapod localities from the Triassic of the SE of European Russia Valentin P. Tverdokhlebova, Galina I. Tverdokhlebovaa, Mikhail V. Surkova,b, Michael J. Bentonb,* a Geological Institute of Saratov State University, Ulitsa Moskovskaya, 161, Saratov 410075, Russia b Department of Earth Sciences, University of Bristol, Bristol, BS8 1RJ, UK Received 5 November 2001; accepted 22 March 2002 Abstract Fossil tetrapods (amphibians and reptiles) have been discovered at 206 localities in the Lower and Middle Triassic of the southern Urals area of European Russia. The first sites were found in the 1940s, and subsequent surveys, from the 1960s to the present day, have revealed many more. Broad-scale stratigraphic schemes have been published, but full documentation of the rich tetrapod faunas has not been presented before. The area of richest deposits covers some 900,000 km2 of territory between Samara on the River Volga in the NW, and Orenburg and Sakmara in the SW. Continental sedimentary deposits, consisting of mudstones, siltstones, sandstones, and conglomerates deposited by rivers flowing off the Ural Mountain chain, span much of the Lower and Middle Triassic (Induan, Olenekian, Anisian, Ladinian). The succession is divided into seven successive svitas, or assemblages: Kopanskaya (Induan), Staritskaya, Kzylsaiskaya, Gostevskaya, and Petropavlovskaya (all Olenekian), Donguz (Anisian), and Bukobay (Ladinian). This succession, comprising up to 3.5 km of fluvial and lacustrine sediments, documents major climatic changes. At the beginning of the Early Triassic, arid-zone facies were widely developed, aeolian, piedmont and proluvium. These were replaced by fluvial facies, with some features indicating aridity. -

The results of the integrated (U-Pb age, Lu-Hf isotopic system and trace-elements) study of detrital zircons (dZr) from the Ordovician sandstones (within Sol-Iletsk arch) reached by borehole Ordovician-2 are presented. The primary sources of Early Precambrian dZr were most likely the crystalline complexes of the Late Proterozoic Volgo-Sarmatian and Taratash orogens and Archean Volga-Uralia basement. However, for numerous dZr with ages younger 1.65Ga, it is not possible presently to unambiguously identify primary sources. Crystalline complexes with such ages are absolutely atypical for the south-eastern part of the EEP, but they occurred within parts EEP very remote from Sol-Iletsk arch and beyond EEP. -

Reid and Marina I. Orlova1 Abstract: Between 1985 and 2000, ~70% of new species that invaded the North American Great Lakes were endemic to the Ponto-Caspian (Caspian, Azov, and Black seas) basins of eastern Europe. Sixteen Ponto-Caspian species were also established in the Baltic Sea as of 2000. Many Ponto-Caspian endemic species are characterized by wide environmental tolerances and high phenotypic variability. Ponto-Caspian fauna evolved over millions of years in a series of large lakes and seas with widely varying salinities and water levels and alternating periods of isolation and open connections between the Caspian Sea and Black Sea depressions and between these basins and the Mediterranean Basin and the World Ocean. These conditions probably resulted in selection of Ponto-Caspian endemic species for the broad environmental tolerances and euryhalinity many exhibit. Both the Baltic Sea and the Great Lakes are geologi- cally young and present much lower levels of endemism. The high tolerance of Ponto-Caspian fauna to varying environmental conditions, their ability to survive exposure to a range of salinities, and the similarity in environmental conditions available in the Baltic Sea and Great Lakes probably contribute to the invasion success of these species. Human activities have dramatically increased the opportunities for transport and introduction and have played a cata- lytic role. Résumé : Entre 1985 et 2000, environ 70 % des espèces qui ont envahi pour la première fois les Grands-Lacs d’Amérique du Nord étaient endémiques aux bassins versants de la région pontocaspienne de l’Europe de l’Est, soit ceux de la mer Caspienne, de la mer d’Azov et de la mer Noire. -

Crustal thickness By analyzing regional trends in crustal structure and links to tectonic evolution illustrated by a new tectonic map, Crystalline crust we conclude that: (1) Each tectonic setting shows significant variation in depth to Moho and crustal structure, Sedimentary cover essentially controlled by the age of latest tectono-thermal processes; (2) Published global averages of crustal pa- Pn velocity rameters are outside of observed ranges for any tectonic setting in Europe; (3) Variation of Vp with depth in the Crustal evolution sedimentary cover does not follow commonly accepted trends; (4) The thickness ratio between upper-middle (Vp b 6.8 km/s) and lower (Vp N 6.8 km/s) crystalline crust is indicative of crustal origin: oceanic, transitional, platform, or extended crust; (5) Continental rifting generally thins the upper-middle crust significantly without changing Vp. -

D. EVANS Department of Geology & Geophysics, Yale University, New Haven, CT 06520-8109, USA (e-mail: [email protected]) Abstract: Palaeomagnetic apparent polar wander (APW) paths from the world’s cratons at 1300–700 Ma can constrain the palaeogeographic possibilities for a long-lived and all-inclusive Rodinia supercontinent. Laurentia’s APW path is the most complete and forms the basis for super- position by other cratons’ APW paths to identify possible durations of those cratons’ inclusion in Rodinia, and also to generate reconstructions that are constrained both in latitude and longitude relative to Laurentia. Baltica reconstructs adjacent to the SE margin of Greenland, in a standard and geographically ‘upright’ position, between c. 1050 and 600 Ma. Australia reconstructs adja- cent to the pre-Caspian margin of Baltica, geographically ‘inverted’ such that cratonic portions of Queensland are juxtaposed with that margin via collision at c. 1100 Ma. Arctic North America reconstructs opposite to the CONgo þ Sa˜o Francisco craton at its DAmaride–Lufilian margin (the ‘ANACONDA’ fit) throughout the interval 1235–755 Ma according to palaeomag- netic poles of those ages from both cratons, and the reconstruction was probably established during the c. -

The new model of sediments, implying their thickness and density, demonstrates several important features of the sedimentary cover, which were not or differently imaged by previous studies. We found a significant redistribution of the low-dense sediments in the Black Sea. Another principal feature is the increased thickness of relatively low-dense sediments in the Eastern Greater Caucasus. The deepest part of the South Caspian basin is shifted to the north, close to the Apsheron Trough. In its present position, it is almost joined with the Terek–Caspian depression, which depth is also increased.
