Context: Ukraine struck two Russian civilian oil tankers — Kairos and Virat — in the Black Sea using sea drones, causing major damage to vessels believed to be transporting sanctioned Russian oil.
About Black Sea:
What it is?
- The Black Sea is a large inland sea connected to the Mediterranean through a chain of straits. It is known for its unique stratified water system, where deep layers lack oxygen and are filled with hydrogen sulfide, creating a biologically “dead zone.”
Location: Situated at the southeastern extremity of Europe, the Black Sea lies between Eastern Europe, the South Caucasus, and Anatolia.
Neighbouring Nations: It is bordered by Ukraine, Russia, Georgia, Turkey, Bulgaria and Romania.
Key Features:
- Shape & Size: Roughly oval-shaped basin; area ~163,000 sq. miles (422,000 sq. km).
- Connection: Linked to the Mediterranean via the Bosporus to Sea of Marmara to Dardanelles to Aegean Sea.
- Depth: Maximum depth exceeds 7,250 feet (2,210 m).
- Stratified waters:
- Upper layers: oxygenated, biologically productive.
- Below ~150–200 m: anoxic (no oxygen), filled with hydrogen sulfide, supporting only anaerobic bacteria.
- Geology: Remnant of the ancient Tethys Sea, transformed over millions of years by tectonic uplift.
- Climate: Northern parts experience cold steppe climate; southern coasts more humid and subtropical.
Significance:
- Key geopolitical flashpoint involving NATO, Russia, Ukraine, and Turkey; crucial maritime route for oil, grain, and military logistics.
- Supports commercial fisheries, shipping lanes, tourism, and provides access to global trade routes.
- Hosts rich biodiversity in upper layers, while deep anoxic layers preserve ancient shipwrecks in near-perfect condition.
