The Caspian Sea is the world's largest inland body of water, described as the world's largest lake and usually referred to as a full-fledged sea. [2] [3] [4] An endorheic basin, it lies between Europe and Asia: east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau.
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

To fill the Caspian basin to a level of more than 50 metres (160 ft) would require as much as 70,000 km 3 of water, equivalent to 200 years of river discharge into the Caspian Sea. Water flowed through the Manych Spillway (250 to 1,000 km 3 per year) and some (more than 100 km 3 per year) was lost through evaporation.
The Caspian's water levels, which have fluctuated sharply during the last century, have been falling since the mid 1990s, scientific studies have found. ... discussed with Russian President ...
Mt. Laurel–Wenonah aquifer; Ogallala Aquifer, also known as the High Plains Aquifer; Ozark Plateau aquifer; Patapsco aquifer; Permian Sea; Potomac–Raritan–Magothy aquifer; Saginaw Aquifer; San Diego Formation [1] San Joaquin River aquifer; Sankoty Aquifer; Silurian–Devonian aquifers; Spokane Valley–Rathdrum Prairie Aquifer [2] [3]
The change in the total mass of ice on land, called the mass balance, is important because it causes changes in global sea level. High-precision gravimetry from satellites in low-noise flight has determined that in 2006, the Greenland and Antarctic ice sheets experienced a combined mass loss of 475 ± 158 Gt/yr, equivalent to 1.3 ± 0.4 mm/yr ...
The maximum water depth of the lagoon in spring and in the western areas of the lagoon reaches 2.5 meters, which varies due to the fluctuations of the water level of the Caspian Sea. • 9.53%: forest and pasture • 2.33%: Agricultural lands • 7.8%: wetlands, dams and pools • 7.3%: areas used privately by people.

The water body lends its name to the nearby city of Garabogaz. The name was originally applied to the narrow strait which connects the gulf to the Caspian Sea. Because the water in the strait, termed a "throat" (Turkmen: bogaz), was darker than the water on either side, it was termed "dark" or "black" (Turkmen: gara), hence garabogaz. Over time ...
