These envelopes nevertheless limit observation of the ice giants' interiors, and thereby the information on their composition and evolution. [2] Although Uranus and Neptune are referred to as ice giant planets, it is thought that there is a supercritical water-ammonia ocean beneath their clouds, which accounts for about two-thirds of their ...
Other terms, such as grease ice and pancake ice, are used for ice crystal accumulations under the action of wind and waves. [citation needed] When sea ice begins to form on a beach with a light swell, ice eggs up to the size of a football can be created. [8] Nilas designates a sea ice crust up to 10 centimetres (3.9 in) in thickness. It bends ...
A pressure ridge, when consisting of ice in an oceanic or coastal environment, is a linear pile-up of sea ice fragments formed in pack ice by accumulation in the convergence between floes. Such a pressure ridge develops in an ice cover as a result of a stress regime established within the plane of the ice.
Planetary oceanography, also called astro-oceanography or exo-oceanography, [1] is the study of oceans on planets and moons other than Earth.Unlike other planetary sciences like astrobiology, astrochemistry, and planetary geology, it only began after the discovery of underground oceans in Saturn's moon Titan [2] and Jupiter's moon Europa.

In addition, contrary to Miles' theory, this theory does predict that no wave growth can occur if the wind speed is below a certain value. Miles theory predicts exponential growth of waves with time, while Phillips theory predicts linear growth with time. The linear growth of the wave is especially observed in the earliest stages of wave growth.
One by one, and ever so slowly, an entire flotilla of massive chunks of ice several stories high gradually make t. Residents view the first iceberg of the season as it passes the South Shore, also ...
Sea ice will deform primarily at fracture points which in turn will form at the points of greatest stress and lowest strength, or where the ratio between the two is a maximum. Ice thickness, salinity and porosity will all affect the strength of the ice. The motion of the ice is driven primarily by ocean currents, though to a lesser extent by wind.
El Niño event brings ocean-wide waves. The El Niño event is accompanied by oceanic downwelling Kelvin waves.This occurs when a thick, warm layer of the Pacific Ocean sloshes east — creating an ...
