Ukraine (Listeni/juːˈkreɪn/; Ukrainian: Україна, transliterated: Ukrayina, [ukrɑˈjinɑ]) is a country in Eastern Europe. It has an area of 603,628 km2 (233,062 sq mi), making it the largest country entirely within Europe. Ukraine borders Russia to the east and northeast, Belarus to the northwest, Poland, Slovakia and Hungary to the west, Romania and Moldova to the southwest, and the Black Sea and Sea of Azov to the south and southeast, respectively.
The Sea of Azov is the shallowest sea in the world, reaching maximum depths of just 14 metres. The warm, nutrient-rich water is full of algae. In the summer, brightly coloured swirls of green algal blooms can be seen from space.
"An intense bloom of phytoplankton is seen in the Black Se, staining it with a rich palette of teal, turquoise, green and milky blue. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite acquired this true-colour image on June 3rd, 2012."
The Milky Way sinking into the Black Sea | The Black Sea is a body of water in Southeastern Europe, bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. It is supplied by a number of major rivers, such as the Danube, Dnieper, Rioni, Southern Bug, and Dniester. The Black Sea has an area of 436,400 km2 (168,500 sq mi) (not including the Sea of Azov), a maximum depth of 2,212 m (7,257 ft), and a volume of 547,000 km3 (131,000 cu mi).
Ukrainian Navy has continued the scheduled survey of the hydrological and hydro-meteorological conditions of the Black and Azov Seas. On Friday, November 15, specialized vessel Pereyaslav with a group of navigational and hydrographic and hydro-meteorological support put out to sea for the second hydro-geographical expedition in this year.
