Ice shelf
An ice shelf is a thick, floating platform of ice extending from a glacier or ice sheet over the ocean, found around Antarctica and parts of the Arctic.
Ice shelf collapse
Ice shelf collapse is the rapid disintegration of a floating Antarctic ice shelf into thousands of small icebergs, as with Larsen A in 1995 and Larsen B in 2002.
Ice skate
Ice skate: boot-mounted blade for gliding on ice, used in figure skating, hockey, and speed skating. Evolved from bone runners to metal blades, hollow-ground edges, and the hinged clap skate.
Ice skating
Ice skating: gliding on ice on bladed boots, spanning figure skating, speed skating, short track, and synchronized skating under the ISU (founded 1892). Covers Olympic history, judging, blade physics, ice preparation, and injuries.
Ice Spice
Ice Spice, whose real name is Isis Naija Gaston, is an American rapper from the Bronx. She broke out in late 2022 with the single "Munch (Feelin' U)."
Ice spike
Ice spike: an inverted-icicle-shaped ice formation growing upward from freezing water, formed when expanding ice extrudes water through a hole in the surface crust (Bally-Dorsey model). Favored near -7°C, with pure water and moving air; distinct from penitentes.
Ice Station Zebra
Ice Station Zebra is a 1968 John Sturges Cold War thriller from Alistair MacLean's novel, starring Rock Hudson, Ernest Borgnine, and Patrick McGoohan; a US nuclear submarine races Soviets to recover a downed spy satellite at the North Pole.
Ice stock sport
Ice stock sport (Eisstockschießen) is an Alpine sliding sport related to curling, played on ice in winter and asphalt in summer. Governed by the IFI (founded 1950, 40+ countries), it features team, target, and distance disciplines with a 566 m record.
Ice storm
An ice storm, also called a silver thaw, is a period of freezing rain that coats trees and power lines with glaze ice, causing widespread outages.
Ice stream
An ice stream is a band of fast-flowing ice within an ice sheet, moving far faster than the ice beside it and draining ice toward the ocean.
Ice structuring protein
Ice structuring protein (ISP), also called antifreeze or ice-binding protein, binds ice crystals to control their growth, used mainly in ice cream; the commercial type III HPLC 12 from ocean pout is GRAS in the US via GRN 117.
ICE trial (NCT05731973)
The ICE trial (NCT05731973) was a Dutch randomized trial comparing intercostal nerve cryoablation with thoracic epidural analgesia for pain control after the Nuss procedure for pectus excavatum.
Ice VIIt
Ice VIIt is a high-pressure crystalline phase of water ice between ice VII and ice X, identified at the University of Nevada, Las Vegas in 2022.
Ice wedge
An ice wedge is a vertical, wedge-shaped mass of ground ice in permafrost, grown over centuries by repeated winter cracking, that forms polygonal patterns across Arctic tundra.
Ice wine
Ice wine (Eiswein, vin de glace): dessert wine from grapes frozen on the vine and pressed frozen, per OIV rules at −7°C or colder. Made in Canada's Niagara and Okanagan, Finger Lakes, and Mosel; first recorded in Franconia in 1794, first commercial Canadian Icewine 1983.
Ice Worm
Ice Worm is NASA's Jet Propulsion Laboratory ice-climbing robot, adapted from a limb of the LEMUR robot, built to demonstrate mobility on Europa, Enceladus, and Earth glaciers.
Ice XVI
Ice XVI is a low-density crystalline form of water, first prepared in 2014 by emptying the cages of a neon clathrate hydrate, with a density of 0.81 g cm⁻³.
Ice XVII
Ice XVII is a metastable, porous crystalline phase of water ice, first produced in 2016 by emptying hydrogen from the C0 hydrate; its helical channels reversibly adsorb hydrogen.
Ice XXI
Ice XXI is a metastable, high-density phase of ice formed from supercompressed liquid water at room temperature, reported in 2025 as the 21st crystalline ice phase.
Ice-albedo feedback
The ice-albedo feedback is a positive climate feedback in which warming melts reflective snow and sea ice, exposing darker surfaces that absorb more sunlight and drive further warming.
Ice-Candy-Man
Ice-Candy-Man is a 1988 novel by Pakistani writer Bapsi Sidhwa, published in the United States as Cracking India, depicting the 1947 partition of India through a young Parsee girl in Lahore.
Ice-jam flood
An ice-jam flood is a flood caused by an accumulation of river ice that blocks the channel, producing water depths two to three times higher than open-water floods at the same flow.
Ice-nine
Ice-nine is Vonnegut's fictional ice polymorph from Cat's Cradle (1963), stable at room temperature and freezing all water it touches; the real ice IX, found in 1967, is a metastable, hydrogen-ordered low-temperature form of ice III.
Ice-rafted debris
Ice-rafted debris (IRD), also called ice-rafted detritus, is sediment carried by floating ice and released to the seafloor when it melts, used as a paleoclimate proxy for past iceberg discharge.
Ice-sheet model
An ice-sheet model is a numerical model simulating the flow, thickness, temperature, and mass balance of ice sheets, particularly for predicting their response to climate change under climate forcing.
Ice-T
Ice-T (Tracy Marrow, born 1958, Newark) is an American rapper and actor, a pioneer of gangsta rap with Rhyme Pays (1987), frontman of Body Count whose "Cop Killer" (1992) sparked a free-speech controversy, and Detective Fin Tutuola on Law & Order: SVU since 2000.
Ice-Tethered Profiler
The Ice-Tethered Profiler (ITP) is an autonomous oceanographic instrument developed at Woods Hole that profiles the upper ocean beneath drifting Arctic sea ice and transmits data via satellite.
Ice-type model
The ice-type model is a lattice model in statistical mechanics where each vertex carries arrows obeying the ice rule, modeling proton disorder in water ice.
Iceberg
Iceberg: a mass of freshwater ice calved from a glacier or ice shelf floating in open water, at least 5 m above sea level. Also called tabular bergs (Antarctic) and growlers, bergy bits (smaller fragments); 13% above water, monitored by IIP and NIC.
Iceberg B-15
Iceberg B-15 was a tabular iceberg that calved from Antarctica's Ross Ice Shelf in March 2000, the largest reliably measured by satellite at about 11,000 square kilometers.
