EUROPE SEA DIVERSITY • Europe is surrounded by four sea regions: the Mediterranean, Black and Baltic Seas, and the North Atlantic Ocean which also includes the North Sea. Europe also conducts many maritime activities in the Arctic. • Europe’s seas include the Baltic, Black, North-East Atlantic and Mediterranean seas. The North-East Atlantic includes the North Sea, but also the Arctic, Barents, Irish and Celtic Seas, the Bay of Biscay and Iberian Coast. •The Baltic Sea • The Baltic is the youngest sea on our planet, emerging from the retiring ice masses only some 10,000-15,000 years ago. • Governed by special hydrographical and climatic conditions, the Baltic Sea is one of the planet’s largest bodies of brackish water. It is composed of salt water from the North East Atlantic and fresh water from rivers and streams draining from an area four times larger than the Sea itself. This highly sensitive and interdependent marine ecosystem gives rise to unique flora and fauna.

It covers an area, including the Sea of Marmara but excluding the Black Sea, of about 970,000 square miles. The Mediterranean Sea has significant endemism and is biologically distinctive from the adjacent Atlantic Ocean. • Its rocky reefs, seagrass meadows, and upwelling areas are particularly important habitats that support enormous biodiversity. Seagrass meadows provide important habitat, especially as breeding, feeding, and resting areas for numerous marine species, particularly fish, crustaceans, and marine turtles. • These meadows produce more than 80% of the annual fish yield in the Mediterranean. The grasses also stabilise the seashore and maintain water quality, particularly through oxygen production. The rocky reef ecosystems provide habitat for the endangered Mediterranean monk seal (Monachus monachus) as well as several endemic fish and invertebrates. The Ligurian Sea represents the most significant upwelling area in the Mediterranean. The Mediterranean is home to several endangered marine species • the monk seal (Monachus monachus), of which only an estimated 550-600 animals remain. • the green turtle (Chelonia mydas) and the 100-million year old loggerhead turtle (Caretta caretta), which nest on Mediterranean beaches. • cetacean species, including the pilot whale, the fin whale and the short-beaked common dolphin. THE MONK SEAL BLACK SEA • The Black Sea is a sea between Southeastern Europe and Western Asia. It is bounded by Europe, Anatolia and the Caucasus, and drains through the Mediterranean into the Atlantic Ocean, via the Aegean Sea and various straits. The Bosphorus Strait connects it to the Sea of Marmara, and the Strait of the Dardanelles connects that sea to the Aegean Sea region of the Mediterranean. These waters separate eastern Europe and western Asia. The Black Sea is also connected to the Sea • Back Sea is the world's largest land-locked and anoxic sea. • More than 171 million people, in 21 countries, live in the region draining into the Black Sea. • The Black Sea has a surface area of 461,000 square kilometers. • The Black Sea has an average depth of 1,240 meters, but about 25 percent is less than 200 meters deep. • The Black Sea is linked to the Mediterranean by the Dardanelles, which is very shallow and very narrow. • The surface water temperature varies seasonally and geographically between 0 degrees C and 25 degrees C, while the deep water (1000 meters) remains a constant 9 degrees C. • The water below 150 meters in depth contains no oxygen and contains high concentrations of hydrogen sulfide (H2S). • There are 180 species of fish in the Black Sea. • Twenty-one marine species have been fished to comercial extinction. • Bordered by Bulgaria, Georgia, Romania, Russia, Turkey and Ukraine, the Black Sea and its surrounding areas are marked by majestic scenery and a rich cultural and natural heritage. • This includes not just the sea itself, but the Danube River Delta, Caucasus and Carpathian Mountains as well. The region's waters, coastlines, flooplains and mountains are home to an incredibly diverse range of wildlife and habitats. • Bears, wolves and lynx inhabit the old growth forests. In the Black Sea, one still finds bottlenose dolphins and about 180 species of fish, including tuna, anchovy, herring, mackerel and the famous white sturgeon. Monk seals, sadly, have become extinct here. • The Black Sea is a friendly sea, for there are very few hazardous marine animals Moon jellyfish Aurelia aurita Rhizostome jellyfish Rhizostoma pulmo BLACK SEA SCORPİON FİSH Regional sea characteristics • The Baltic Sea is semi-enclosed with low salinity due to restricted water exchange with the North-East Atlantic and large river run-off. These conditions make the sea particularly vulnerable to nutrient pollution. • The Black Sea is also semi-enclosed; it is the world’s largest inland basin with restricted water exchange with the Mediterranean. Its waters are anoxic at depths below 150 metres to 200 metres. Surface water salinities of the Black Sea are within an intermediate range. Most of the Black Sea is believed to host oil and gas reserves, and oil and gas exploration is under way. • The Mediterranean Sea is also a semi-enclosed sea with high salinity due to high evaporation rates and low river run-off. It has restricted water exchange with the Atlantic and Black seas. It is the most biologically diverse sea in Europe. • The North-East Atlantic covers a range of seas and a large climatic gradient. It is a highly productive area that hosts the most valuable fishing areas of Europe and many unique habitats and ecosystems. It is also home to Europe’s largest oil and gas reserves. • The coast is the area defined by the coming together of the land and the sea. In the 24 EEA coastal countries, there are 560.000 km2 of coastal zones, corresponding to 13% of the total land mass of these countries based on Corine Land Cover data from 2000. • The deep sea and sea floor forms an extensive and complex system which is linked to the rest of the planet in exchanges of matter, energy and biodiversity. The functioning of deep-sea ecosystems is crucial to global biogeochemical cycles upon which much terrestrial life, and human civilisation, depend. It is found both in European and international waters of the Atlantic and in the Arctic Ocean. The deep sea is usually considered to be that found at depths greater than 400 metres.
