Ice rafting is the transport of various material 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 may be used for analysis of ice drift pattern by matching the rafted sediment with its origin.[1][2]
