The Cenomanian/Turonian oceanic anoxic event as recorded in many parts of the world is characterized by presence of black shales and global carbon isotope peaks. Cyclic variations within the anoxic event and association with pelagic red beds are indicated by many studies. Global tectonic/volcanic controls on the origin and the chronostratigraphic position of the anoxic event within the global sea-level changes are important for understanding the paleoceanographic and paleoclimatic conditions during the deposition of Cenomanian/Turonian sediments.

Zooplankton of the Black Sea and the Eastern Mediterranean Similarities and dissimilarities Kovalev, Av; Mazzocchı, Mg; Sıokoufrangou, I.; Kıdeyş, Ahmet Erkan (2001-01-01) A synthesis of data on abundance and biomass of zooplankton in the Eastern Mediterranean (EMED) and the Black Sea shows major differences in the composition and structure of pelagic communities in the two basins. Few Mediterranean planktonic animals have invaded in the Black Sea. The great bulk of Black Sea species is represented by coastal inhabitants that spread throughout the whole basin. This process has been called “neritization” of the Black Sea fauna. Peculiarities in zooplankton assemblages of the B...
Sea level changes along the peninsular Malaysia and Sabah and Sarawak coastlines for the 21st century Ercan, Ali; Kavvas, M. Levent; Mohamad, Mohd Fauzi (2011-07-21) Sea level change over the global system has been studied by various observations during the historical period, and by Atmosphere-Ocean coupled Global Climate Models or General Circulation Models (AOGCMs) during 2000 - 2100 (IPCC Fourth Assessment Report). In this study, an introductory analysis on sea level change around the Peninsular Malaysia and Sabah and Sarawak coastlines during the 21st century is presented. The variation of the sea level change with respect to the spatial location along the Peninsula...
Seasonality of Mesozooplankton in the Southern Black Sea off Sinop Between 2002 and 2004 Üstün, Funda; Bat, Levent; Şahin, Fatih; Birinci Özdemir, Zekiye; Kıdeyş, Ahmet Erkan (2016-12-01) The monthly and long-term fluctuations of mesozooplankton abundance, biomass, and taxonomic composition in the Sinop inner harbor (southern Black Sea) between 2005 and 2009 are presented in the present study. In total, 31 mesozooplankton taxa were identified during the study. The recorded average mesozooplankton abundance and biomass were 34,323 ± 7580 ind. m and 1208 ± 460 mg m in 2005, 95,063 ± 31,434 ind m and 1787 ± 604 mg m in 2006, 97,626 ± 12,141 ind m and 1034 ± 20 mg m in 2007, 91,918 ± 10,476 ind ...
Basement structure and architecture of the Black Sea Basin Kaymakcı, Nuretdin; Horn, Brian (null; 2018-01-28) Black Sea consists of two separate back arc basins which opened at different times during the Cretaceous in response to northward subduction of the Neo-Tethys Ocean. The paucity of well data, complex geometries and seismic imaging challenges mean that questions remain regarding the basement architecture though most authors accept that, at least in part, both these basins are floored by oceanic crust, even though there are no magnetic stripes. Interpretation of deep, long offset seismic data (imaging to more...
IMMOBILE TRACE ELEMENT SYSTEMATICS OF OCEANIC ISLAND BASALTS: THE ROLE OF OCEANIC LITHOSPHERE IN CREATING THE GEOCHEMICAL DIVERSITY Sayıt, Kaan (2013-06-01) The Earth's mantle is known to be heterogeneous at different scales, which has been generally linked to the presence of diverse mantle reservoirs, some of which are believed to have remained isolated for long periods of time. When oceanic island basalts (OIBs) are subdivided into five distinct end-member groups on the basis of Sr-Nd-Pb isotope systematics, which include DM, EM1, EM2, HIMU and C, trace element systematics do not appear to be effective discriminators as isotopes, though an end-member signatur...
