AbstractWhen glaciers scrape across Antarctica, they pick up rock fragments and incorporate them into their bottom layers while transporting them toward the coast. There, icebergs break off, drifting towards lower latitudes and warmer waters. Along the way the icebergs melt and the rock fragments sink to the seafloor, leaving behind a trail of these rock fragments called ice rafted debris. Ice rafted debris accumulates at the bottom of the ocean and over time preserves a record of activity at their sour
