| Term: | Hummock |
| Definition: | (1) [sea ice] a smooth hill of ice that forms on the sea ice surface from eroding ridges, particularly during the summer melt; the formation of hummocks is similar to young mountain peaks with steep slopes that erode into smooth, rolling hills. (2) [frozen ground] Small lumps of soil pushed up by frost action, often found in uniformly spaced in large groups. Hummocks can form in areas of permafrost or seasonally frozen ground, and are one of the most common surface features of the Arctic. |
| Term: | Hummock |
| Definition: | A mound of broken ice projecting upward, formed by ice deformation. The submerged counterpart of a hummock is termed a bummock. |

NSIDCCryosphere A hillock of broken ice that has been forced upwards by pressure. May be fresh or weathered. The submerged volume of broken ice under the hummock, forced downwards by pressure, is termed a bummock. WMOSeaIce Sea ice terminology, meaning a hillock of broken ice which has been forced upwards by pressure; it may be fresh or weathered. ECCCanada A hillocky conglomeration of broken ice formed by pressure at the place of contact of the angle of one ice floe with anther ice floe. The underwater portion of a hummock is termed a bummock. Bushuyev A mound of broken ice projecting upward, formed by ice deformation. The submerged counterpart of a hummock is termed a bummock. AMSglossary A mound or hillock of broken floating ice forced up by pressure. May be fresh or weathered. A corresponding projection may also occur on the underside of the ice canopy and is called a bummock. SPRI GCW |
