Terrigenous <strong>sediments</strong><strong>Ocean</strong> circulations receive the terrigenous <strong>sediments</strong> – eolian, fluvial,ice rafted debris (IRD) - from the continents. The particles sink <strong>and</strong>circulate within the different water masses <strong>and</strong> ultimately end up atthe <strong>sea</strong>bed.Which regions most likely generate most of the wind blown dust?Which regions contain most of the IRD?What is the major contrast between eolian <strong>and</strong> fluvial <strong>sediments</strong>?Why are volcanic ash layers important in marine geology?Where would you expect to have sediment erosion <strong>and</strong> wheredeposition?
