Seabed gouging by ice is a process that occurs when floating ice features (typically icebergs and sea ice ridges) drift into shallower areas and their keel comes into contact with the seabed. [1][2][3] As they keep drifting, they produce long, narrow furrows most often called gouges, or scours. [4][5][6] This phenomenon is common in offshore ...

Ice scour is the phenomenon that occurs when the keel of a floating mass of ice (iceberg, sea ice or freshwater ice) touches, penetrates and continues to move forward through unlithified seabed or lakebed sediments.

Hydrodynamic scour, the removal of sediment such as sand and silt from around an object by water flow Bridge scour, erosion of soil around at the base of a bridge pier or abutments via the flow of air, ice, or water

Aug 3, 2020 · The study examined the shallows adjacent to the western Antarctic Peninsula, an area highly disturbed by ice scouring — when icebergs break off from glaciers and gouge the seafloor.

Aug 18, 2021 · Our results show that a broad range of disturbance values are required to detect the predicted peak in biodiversity that is consistent with the Intermediate Disturbance Hypothesis, suggesting ice...

Ice sheets moving over relatively level surfaces have produced large numbers of small lake basins through scouring in many areas. This type of glacial rock basin contains what are known as ice-scour lakes and is represented in North America, for example, by basins in parts…

Jul 18, 2008 · Ice scour is a key structural force acting on benthic communities at high latitudes. It affects one-third of the world's coastlines, yet relatively little is known about the frequencies and the ecological effects of ice scouring compared with other natural disturbances.

Researchers use several approaches to generate information on scouring phenomena and to gain understanding of seabed response to ice gouging. These approaches can be divided into two categories: observations of real events and artificial simulations.

Feb 1, 2019 · Marine structures such as subsea pipelines are at risk of being damaged by deep iceberg-keels. The ice scour process begins when a floating ice mass with a deep keel is driven into shallow water by environmental forces such as winds, water currents and waves.

Aug 20, 1990 · Ice scour is a poorly understood phenomenon which occurs when ice (pressure ridge or lceberg) moves while in contact with the seabed. It is of economic significance due to the like hood of disruption of seabed structures.
