The most unusual inhabitants of the deep sea

The black sea is very suitable for kids: summer storm rare here – because the Black sea is small, the wind is harder to rock the waves ; W here there is almost no dangerous sea animals, and in water less salt, and it doesn’t sting the eyes. Here is to learning how to dive, first to get acquainted with the underwater world.

The black sea is surrounded by land, but it’s not the lake – the Bosporus and the Dardanelles coedine added it to the Mediterranean sea.

The Black sea flows into many rivers, so the salinity of its surface waters is low: 17 ‰ – grams of salt in a liter of water. Due to the low salinity reduced the biodiversity of the Black sea: the inhabitants of the seas and oceans can not tolerate salinity below 20 ‰.

Surface water of the Black sea is less salty and lighter, similar in temperature to the air ; in the summer it warms up. in winter it is cooled. It is familiar to us Black sea: in it, we swim and dive, catch fish.

C ovsem other – deep waters of the Black sea: from 50-100m – to the bottom, lying at a depth of two kilometers is more salty and heavy. their temperature is always constant and: o S. 9 – properties of the waters of the Black sea

Desalinated surface water is almost not mixed with the more saline deep waters: it prevents the penetration of oxygen into the depths of the Black sea. Deeper than 200 meters – the oxygen in the water of the Black sea is missing, the plants and animals there can not live, but live bacteria that break down down the remains of life and produce the hydrogen sulfide.

The aquarium as a piece of art

The aquarium design is the art of creating living art, and as any art it has its canons, rules, directions. Prostozoo hurry to introduce them.

In the late nineteenth century English naturalist Philip Gosse (pictured) asked for an indication of glass vessels with water, which are used for marine plants and animals, the word “aquarium”. Accordingly, the science of the content of Averianov, became known as “the aquarium”.

In the nineteenth century aquariums used for scientific purposes: monitoring the marine life. But with the filing of the same Gosse aquariums not only acquired the designation, and expanded the scope of usage, and at the same time a circle of admirers. The restless Englishman in 1853 in London Rigers Park opened the world’s first exhibition of marine aquariums – “Aquatic vivarium”. She liked the audience and it’s still in use (London aquarium). From that moment began a new era aquarium, aquariums have become a highlight and addition to the interior, and its inhabitants – Pets.

The demand is known, creates supply, and once the aquariums crossed the threshold of the houses, appeared the developers, manufacturers of aquarium equipment, the task of which is to make the lives of obitatelyami the most comfortable. Aquarium designers seek not only to combine the contents of aquariums with the interior, but also to make the aquarium its highlight. Continue reading

Black sea

Black sea – an inland sea basin of the Atlantic ocean. The Bosporus connects to the sea of Marmara, then through the Dardanelles with the Aegean and Mediterranean seas. The Kerch Strait connects the sea of Azov. North sea cuts deeply into the Crimean Peninsula. On the surface Black sea water passes the border between Europe and Asia Minor.

A characteristic feature of the Black sea is complete (except for some anaerobic bacteria) absence of life at depths greater than 150-200 m due to the saturation of deep layers of water with hydrogen sulfide.

The climate of the Black sea, due to its mid-continental situation, mainly continental. The black sea coast of Caucasus and the southern coast of the Crimea being protected by mountains from cold Northern winds and as a consequence, have a mild Mediterranean climate and South-East of the Tuapse — humid subtropical climate. A significant impact on the weather over the Black sea has the Atlantic ocean, which originates most of the cyclones at sea bringing bad weather and storms. In the North-East coast, especially in the area of Novorossiysk, low mountains are not a barrier to cold Northern air masses, which, moving through them, cause a strong cold wind (Bora), the locals call it “Nord-OST”.South-westerly winds usually in the black sea region brought a warm and wet Mediterranean air mass. As a result, for the greater part of the territory sea is characterised by warm wet winters and hot dry summers.

The black sea fills the insulated cavity, located between Southeast Europe and Asia Minor. This depression was formed in the Miocene epoch, during an active orogeny that divided the ancient Tethys ocean into several separate water bodies (of which more later, except the Black sea, formed the Azov, Aral and Caspian seas).
