The chlorophyll-a data set established by Turkey, Ukraine, Russia, Bulgaria and Romania was evaluated for the 1990-1996 period and only the surface chlorophyll-a was evaluated and interpreted for different parts of the Black Sea. Three well defined chlorophyll-a maxima were observed in the surface waters in the shelf region: a winter maximum in January-February, a spring-early summer one in May-June and an autumn peak in September-November. One of the expected results was the high level of chlorophyll-a concentration in shelf waters (0.02-34.0 mu gL(-1) as the range of monthly averages) compared to deep regions (0.02-2.5 mu gL(-1)) throughout the whole year. Chlorophyll-a data related to deeper central part of the Black Sea showed different and unusual trends in terms of seasonal and interannual variability's. A late winter blooming continued with slightly decreasing trend till late spring which collapsed during May. The developments of moderate mid-summer and autumn blooms were also observed. A very unusual development of phytoplankton population in 1992 mid-summer caused formation of a chlorophyll-a peak which was almost at the same order of magnitude with winter-spring bloom.

Crimean Tatar factor and Euromaidan in Ukraine's nation building efforts: novelties and changes after 2014 Şahin, Fethi Kurtiy; Aydıngün, Ayşegül; Department of Eurasian Studies (2016) This thesis analyses the impact of the pro-Ukrainian resistance of the Crimean Tatars to the Russian occupation and annexation of the Crimean Peninsula, which started on 26 February, 2014, on the relationship between Ukraine and Crimean Tatars. Additionally, the impacts of the Euromaidan that lasted from October 2013 until February 2014, prior to the Russian occupation of Crimea, on Ukraine’s nation building efforts are studied. This thesis supports the idea that Ukraine has entered a new phase in the natio...
Internal and external dimensions of the Crimean crisis before and after 2014 Demydova, Viktoriia; Tanrısever, Oktay Fırat; Department of Sociology (2017) This work covers the Crimean crisis of 2014, i.e. the EuroMaidan that started in Kyiv, in November 2013, and that was followed by the Anti-Maidan in the Crimea, and, as a result, the proclamation of independence, as well as the unification of the Crimea with Russia via referendum. Contrary to the views of some experts who argue that the Crimean crisis and the annexation of the Crimea as well as the developments in the aftermath of this annexation could be explained with the reference to foreign policies of ...
Factors shaping ethnic identity among Crimean Tatars, Russians and Ukrainians in Crimea Biletska, Yuliya; Aydıngün, Ayşegül; Department of Eurasian Studies (2009) The aim of this thesis is to define factors that are influential in the ethnic identification process of Crimean Tatars, Russians and Ukrainians in Crimea. To better understand the current ethnic situation in Crimea, Soviet nationality policy as well as Soviet ethnos theory are reviewed. The divergence of the definitions in Soviet and Western traditions is shown. Crucial historical events that took place in Crimea are examined from the viewpoints of Russian, Ukrainian, Crimean Tatar, Soviet and Western hist...
The Crimean autonomous region and Ukraine's relations with Russia in the Post-Soviet era Umerov, Eldar; Tanrısever, Oktay Fırat; Department of International Relations (2013) This thesis explores the autonomy of the Crimean region in Ukraine in terms of its impact on Ukraine’s relations with Russia in the post-Soviet era. Thesis analyzes also the impact of the relations between Ukraine and Russia on the autonomy of the Crimean region. Contrary to the views that consider the Crimean autonomy as a product of the ethno-territorial relations between the Crimea which is populated by mainly ethnic Russians and Kiev, thesis argues that the interstate relations between Ukraine and Russi...
Reflections of nationalism and the role of language policies in national identity formation in Post-Soviet Azerbaijan Akyıldız, Selma; Tokluoğlu, Ayşe Ceylan; Department of Eurasian Studies (2019) After the dissolution of the Soviet Union, the newly independent Azerbaijan has entered its nation-building process. Azerbaijani political elites aimed to re-form national identity through a set of language policies. In this context, they focused on the alphabet, and on the name of the official language which they consider as markers of their national identity. Turkism versus Azerbaijanism as the two competing ideologies have left their mark on this process. Language has been used as a political tool for pr...
