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 ...
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. [3]
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.
However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.
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 ...
Despite being the largest animal on the planet, blue whales maintain a life of secrecy, spending their days in the deep, open ocean. ... The ocean giants live in all oceans except the Arctic, NOAA ...
Alien life could be found in a tiny grain of ice, researchers have said. The discovery suggests that upcoming telescopes might be able to spot extraterrestrial life relatively soon.
