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.
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.
(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 s
lopes 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.
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.
Pressure ice characterized by haphazardly arranged mounds or hillocks ("hummocks"). This has less definite form than rafted ice or tented ice, but in fact may develop from either of those as melting,
sublimation, or drifting changes the sharper ice edges into more rounded shapes.
Sea ice terminology, which describes ice that is piled chaotically, one piece over another, to form an uneven surface. When weathered, hummocked ice has the appearance of smooth hillocks.
A form of pressure ice in which pieces of ice are piled haphazardly, one piece over another, to form an uneven surface. When weathered it has the appearance of smooth hillocks.
