Hranice Abyss. Hranice Abyss (Czech: Hranická propast) is the deepest flooded pit cave in the world. It is a karst sinkhole near the town of Hranice, Czech Republic.The greatest confirmed depth is 519.5 m (1,704 ft), of which 450 m (1,476 ft) is underwater.
However, because it is also the deepest lake, [6] with a maximum depth of 1,642 metres (5,387 feet; 898 fathoms), [1] Lake Baikal is the world's largest freshwater lake by volume, containing 23,615.39 km 3 (5,670 cu mi) of water [1] or 22–23% of the world's fresh surface water, [7] [8] more than all of the North American Great Lakes combined.

The overflow provides one of the main inflows of North Atlantic Deep Water, accounting for around half of dense water overflow between the Nordic Seas and the North Atlantic. [ 4 ] [ 5 ] The dense and cold water mass that spills across the overflow, known as Denmark Strait Overflow Water (DSOW), is thought to originate from the modification of ...
The deepest area is oceanic rather than continental crust. However, it is generally regarded by geographers as a large endorheic salt lake. Of these registered lakes; 10 have a deepest point above the sea level. These are: Issyk-Kul, Crater Lake, Quesnel, Sarez, Toba, Tahoe, Kivu, Nahuel Huapi, Van and Poso.
The deepest point of the trench is more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. [a] At the bottom of the trench, the water column above exerts a pressure of 1,086 bar (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%.

Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
