It is possible that the methane ice could float for a time as it probably contains bubbles of nitrogen gas from Titan's atmosphere. [27] Temperatures close to the freezing point of methane (90.4 K; −182.8 °C; −296.9 °F) could lead to both floating and sinking ice - that is, a hydrocarbon ice crust above the liquid and blocks of ...
Thermohaline circulation. Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.
Furthermore, sea ice affects the movement of ocean waters. In the freezing process, much of the salt in ocean water is squeezed out of the frozen crystal formations, though some remains frozen in the ice. This salt becomes trapped beneath the sea ice, creating a higher concentration of salt in the water beneath ice floes.
The ocean is a major driver of Earth's water cycle. Ocean water represents the largest body of water within the global water cycle (oceans contain 97% of Earth's water). Evaporation from the ocean moves water into the atmosphere to later rain back down onto land and the ocean. [69] Oceans have a significant effect on the biosphere.
During his presidency, Jefferson made frequent visits to Monticello, often bringing with him new plants and flowers to be planted. While away, Jefferson wrote instructions to Edmund Bacon, his overseer. [12] Most of the planting was done from 1808 to 1812. After Jefferson's death in 1826, the conditions of the gardens declined rapidly.

The surface salinity of the ocean is a key variable in the climate system when studying the global water cycle, ocean–atmosphere exchanges and ocean circulation, all vital components transporting heat, momentum, carbon and nutrients around the world. [84] Cold water is more dense than warm water and salty water is more dense than freshwater.
