For the overthrusting of one ice sheet over another, see Finger rafting.
Ice rafting is the transport of various materials by ice. Various objects deposited on ice may eventually become embedded in the ice. When the ice melts after a certain amount of drifting, these objects are deposited onto the bottom of the water body, e.g., onto a river bed or an ocean floor.[1][2] These deposits are called ice rafted debris (IRD) or ice rafted deposits. Ice rafting was a primary mechanism of sediment transport during glacial episodes of the Pleistocene when sea levels were very low and much of the land was covered by large masses (sheets) of ice. The rafting of various size sediments into deeper ocean waters by icebergs became a rather important process. Ice rafting is still a process occurring today, although its impact is significantly less and much harder to gauge.
This debris-covered iceberg was calved from the terminus of Alaska's Sheridan Glacier.
The melting of large icebergs deposits sediment of various sizes, usually referred to as glacialmarine sediment, onto the shelf and deeper marine areas.
Ice rafting may be used for analysis of ice drift pattern by matching the rafted sediment with its origin.[1][2]
