An alternative formulation of the phase diagram for certain ices and other phases of water [13] Ice, water, and water vapour can coexist at the triple point, which is exactly 273.16 K (0.01 °C) at a pressure of 611.657 Pa.
The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...
Frazil ice – Collections of ice crystals in open water; Grease ice – Stage in the formation of sea ice; Iceberg – Large piece of freshwater ice broken off a glacier or ice shelf and floating in open water; Ice mélange – Mixture of sea ice types, icebergs, and snow without a clearly defined floe
Ice that is found at sea may be in the form of drift ice floating in the water, fast ice fixed to a shoreline or anchor ice if attached to the seafloor. [45] Ice which calves (breaks off) from an ice shelf or a coastal glacier may become an iceberg. [46] The aftermath of calving events produces a loose mixture of snow and ice known as Ice ...
An iceberg is a piece of fresh water ice more than 15 meters (16 yards) long [1] that has broken off a glacier or an ice shelf and is floating freely in open water. [2] [3] Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits".
Drifting ice station – Research stations built on the ice of the high latitudes of the Arctic Ocean; Iceberg – Large piece of freshwater ice broken off a glacier or ice shelf and floating in open water; Ice shove – Ice pushed onshore due to water movements or wind; Lead (sea ice) – Fracture that opens up in an expanse of sea ice

Some named Antarctic iceshelves. Ice shelf extending approximately 6 miles into the Antarctic Sound from Joinville Island. An ice shelf is "a floating slab of ice originating from land of considerable thickness extending from the coast (usually of great horizontal extent with a very gently sloping surface), resulting from the flow of ice sheets, initially formed by the accumulation of snow ...
