1 All processes that remove snow, ice, or water from a glacier, snowfield, etc ; in this sense, the opposite of accumulation These processes include melting, evaporation, calving, wind erosion, and an avalanche Air temperature is the dominant factor in controlling ablation, precipitation amounts exercising only secondary control During the ablation season (usually summer), an ablation rate of about 2 mm h-1 is typical of glaciers in a temperate climate 2 The amount of snow or ice removed by the above-described processes; in this sense, the opposite of accumulation
elimination or removal Also refers to a procedure that eliminates extra electrical pathways within the heart that cause fast or irregular heart rhythms
The process of removal of the eye in crustaceans This is done to promote moulting and/or spawning The eye stalk is a source of GIH (Gonadotropin Inhibiting Hormone) and so it's removal, reduces or eliminates the signals which are stopping gonadotropins (which start and control the maturation process) from being produced
The removal of surface material from a body by vaporization, melting, chipping, or other erosive process; specifically, the intentional removal of material from a nose cone or spacecraft during high-speed movement through a planetary atmosphere to provide thermal protection to the underlying structure See ablating material
elimination or removal Ablation also refers to a procedure that eliminates extra electrical pathways within the heart that cause fast or irregular heart rhythms
Removal In the case of the excimer laser, the frequency of energy causes the molecules of the cornea to loose the "glue" that holds them together They simply fall away from each other and the remaining cornea
The wearing away of material by mechanical means For a meteoroid, the heat of friction as it passes through the Earth's atmosphere melts and removes those materials at the surface of the object
All processes, which include melting, evaporation (sublimation), wind erosion, and calving (breaking off of ice masses), that remove snow or ice from a glacier or snowfield The term also refers to the amount of snow or ice removed by these processes (Source: Carbon Dioxide Information Analysis Center, 1990)
{i} surgical removal, excision; reduction of the mass of a glacier through the melting and evaporation of snow and ice; burning away of a spacecraft's protective covering during atmospheric reentry
