ice rafting

Ice rafting is a geological process where icebergs transport rocks and sediment over long distances. These icebergs, originating from glaciers or ice sheets, carry debris such as pebbles, cobbles, and boulders. As the icebergs drift and melt in warmer waters, they deposit this material on the ocean floor.12

This process is evident in geological records, such as deep-sea sediment cores, where increases in grain size and specific minerals indicate past ice-rafting events. These events, like the Bond events in the North Atlantic, are associated with climate fluctuations and provide insights into past ocean circulation and ice distribution. Iceberg scours, or furrows left on the seabed when icebergs run aground, are also evidence of this transport mechanism.32
