Figuratively, to “walk on water” is to perform an impossible or godlike task: “When I told him the project had to be done by Tuesday, he made me feel as though I were asking him to walk on water.”

The New Testament story describes Jesus walking on water in the Sea of Galilee, but according to a study led by Florida State University Professor of Oceanography Doron Nof, it’s more likely that he walked on an isolated patch of floating ice.

If you went swimming in the Dead Sea, you wouldn’t see any skeletons or lifeless fish floating on its surface. You also wouldn’t see any big, bad sharks or giant squid hunting in its depths. In fact, you wouldn’t see any sea life at all—plants or animals! The Dead Sea is so salty that nothing can live in it.

In actuality, it is nearly impossible to swim in the Dead Sea. Contact with the water of the Dead Sea is not toxic to human skin, however, the water may cause stinging in open cuts or wounds, according to Frommer’s. …

The Black Sea plankton includes some large marine organisms, such as scyphozoan jellyfish and ctenophores. The most diverse and interesting marine life of the Black Sea is in the rocky bottom habitats. In very shallow water, we find multicolored macroalgae, motley bright blennies, shrimps, and sea anemones.

In addition, the anoxic nature of the Black Seawater, due to which the process of decomposition is slow in the lower water layers, has also resulted in several scary rumours, making the sea infamous. However, as time passed, the image of the Black Sea, as one of the most difficult water bodies to navigate, has changed.

With rivers providing an abundant supply of fresh water, the upper layers of the Black Sea are less dense than its saltier lower layers. Furthermore, a high concentration of hydrogen sulfide, an extremely toxic gas, lies dormant in the deepest layers of the Black Sea.

The Black Sea is home to world’s biggest, most productive spiny dogfish sharks, but this remarkable, global species is in danger of extinction.

Some scientists call it a saline lake (salinity 18 %o, i.e., brackish) even now. It is connected to the Mediterranean sea by the Bosporus strait. Hence the sea was called the black sea. The Black sea has brackish or saline water and hence calling this huge water body of 4,13,360 sq.

Why is the Black Sea black? The sea was first named by the ancient Greeks who called it “Inhospitable Sea.” The sea got this reputation because it was difficult to navigate, and hostile tribes inhabited its shores.

Although a vast majority of seawater is found in oceans with salinity around 3.5%, seawater is not uniformly saline throughout the world. The planet’s freshest (least saline) sea water is in the eastern parts of Gulf of Finland and in the northern end of Gulf of Bothnia, both part of the Baltic Sea.

The Dead Sea salt content is derived from rocks on the land that are eroded by rainwater. These acids slowly break the rocks down over time, creating charged particles called ions that eventually find their way to the Dead Sea, oceans, and other bodies of salt water through runoff. …

Dead Sea

It is stated that the salt content of the water body is so high that no organism can survive there. The ships cannot sail through the water, there either. The salt content prohibits any living organism from getting in the body of water. To answer the raised question precisely, no, ships cannot sail in the Dead Sea.

A sea without salt would decimate marine life and dramatically affect our weather and temperatures, making human life on Earth very difficult, if not impossible. There are roughly 228,450 species in the ocean, and as many as 2 million more to be discovered. But for the most part, all saltwater species would perish.

Everybody Google it. Because that’s why the water is salty. From the [expletive] whale sperm.” In fact, the saltiness “comes from many millions of years of water flowing over rocks and minerals,” according to oceanographer Simon Boxall.
