Batumi in the context of "Tsemes Bay"

The Black Sea is a marginal sea lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper and Dniester. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe.

The Black Sea, not including the Sea of Azov, covers 436,400 km (168,500 sq mi), has a maximum depth of 2,212 m (7,257 ft), and a volume of 547,000 km (131,000 cu mi).Most of its coasts ascend rapidly.These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north.In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farther north. The longest east–west extent is about 1,175 km (730 mi). Important cities along the coast include (clockwise from the Bosporus) the northern suburbs of Istanbul, Burgas, Varna, Constanța, Odesa, Yalta, Kerch, Yevpatoria, Sevastopol, Novorossiysk, Sochi, Poti, Batumi, Rize, Trabzon, Ordu, Simferopol, Samsun and Zonguldak.

Adjara (Georgian: აჭარა Ach’ara [at͡ʃʼara] ) or Achara, officially known as the Autonomous Republic of Adjara (Georgian: აჭარის ავტონომიური რესპუბლიკა Ach’aris Avt’onomiuri Resp’ublik’a [atʃʼaris avtʼonomiuri respʼublikʼa] ), is a political-administrative region of Georgia. It is in the country's southwestern corner, on the coast of the Black Sea, near the foot of the Lesser Caucasus Mountains, north of Turkey. It is an important tourist destination and includes Georgia's second most populous city of Batumi as its capital. About 401,100 people live on its 2,880 km (1,110 sq mi).

Adjara is home to the Adjarians, a regional subgroup of Georgians. The name can be spelled in a number of ways: Ajara, Ajaria, Adjaria, Adzharia, Atchara and Achara. Under the Soviet Union, Adjara was part of the Georgian Soviet Socialist Republic as the Adjarian ASSR. The autonomous status of Adjara is guaranteed under article 6 of the Treaty of Kars.

Located in the city of Batumi, on the south-east coast of the Black Sea. The port is also used as a major transit port for oil refining in Kazakhstan and Azerbaijan. Batumi Port has the ability to meet customer requirements for various cargo, ships and passengers. The port has five terminals: oil terminal, dry cargo terminal, container terminal, railway-ferry crossing and passenger terminal.

The Baku–Batumi pipeline is the name given to several pipeline projects to transport kerosene and crude oil from the Caspian region to the Georgian Batumi oil terminal at the Black Sea. When first constructed in 1906, it was the world's longest kerosene pipeline.

The Batum oblast was a province (oblast) of the Caucasus Viceroyalty of the Russian Empire, with the Black Sea port of Batum (present-day Batumi) as its administrative center. The Batum oblast roughly corresponded to the present-day Adjara autonomous region of Georgia, and most of the Artvin Province of Turkey.
