ice cap

(hydrology) A perennial cover of ice and snow in the shape of a dome or plate on the summit area of a mountain through which the mountain peaks emerge. A perennial cover of ice and snow on a flat land mass such as an Arctic island.

Ice Cap can keep its cool, but it also knows when it's time to turn up the heat. The company manufactures zoned comfort products, or packaged thermal air conditioners (PTAC) and packaged thermal heat pumps (PTHP) for both the new construction and renovations markets. The company's products can be found in government offices, hospitals, hotels, office buildings, schools, and residential construction. Ice Cap primarily serves the New York high-rise market, but also counts Illinois Masonic Home, the University of Tennessee, and the Pennsylvania National Guard as customers. The company was founded in 1972.

A flattened, dome-shaped mass of ice, similar to an ice sheet, but under 50 000 km² in area, such as the Barnes Ice Cap of Baffin Island, Canada. An ice cap does not necessarily obliterate relief. An ice-cap climate is a climatic regime where the average yearly temperature is below 0 °C. Ice and snow are permanent and precipitation is very light.

Vatnajökull, Iceland

An ice cap is a dome-shaped ice mass that covers less than 50 000 km² of land area (usually covering a highland area). Masses of ice covering more than 50 000 km² are termed an ice sheet.^[1][2]

Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains) but their dome is usually centred around the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery.^[1]

Vatnajökull is an example of an ice cap in Iceland.^[3]
