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.
The normal high-water mark is 2.00 feet (0.61 m) above datum (577.5 ft (176.0 m)). In October 1986, Lakes Michigan and Huron reached their highest level at 5.92 feet (1.80 m) above datum. [27] The monthly average high-water records were broken for several months in a row in 2020. [28] Lake levels tend to be the lowest in winter.
The ocean skin temperature is defined as the temperature of the water at 20 μm depth. This means that the SST skin is very dependent on the heat flux from the ocean to the atmosphere. This results in diurnal warming of the sea surface, high temperatures occur during the day and low temperatures during the night (especially with clear skies and ...
In oceanography, sea state is the general condition of the free surface on a large body of water—with respect to wind waves and swell—at a certain location and moment. A sea state is characterized by statistics, including the wave height, period, and spectrum. The sea state varies with time, as the wind and swell conditions change.
The level of the lake is subject to variations according to the inflow, reaching a maximum area of 415 square kilometers (160 sq mi) in periods of high water and down to 210 square kilometers (81 sq mi) in periods of low water. The depth fluctuates between 1 meter (3 ft 3 in) and 3 meters (9.8 ft). [4]

The bay is relatively shallow and is considered an epicontinental sea, with an average depth of about 100 m (330 ft) (compared to 2,600 m (8,500 ft) in the Bay of Bengal). It is about 1,370 km (850 mi) long and 1,050 km (650 mi) wide. [ 6 ]
