Objective
Research objectives and content
Distribution of volcaniclastic material in deep-sea sediments around Iceland is influenced by eruption processes and climate variability in the North Atlantic region. Drilling during Leg 162 of the Ocean Drilling Program recovered numerous well preserved volcaniclastic layers which are derived from fallout from large explosive eruptions, and from catastrophic glacier floods occurring m Iceland. Sedimentological and chemical analysys of these volcaniclastic deposits will be carried out in order to understand the processes and factors controlling their distribution. They are expected to provide an excellent record of the source and timing of major Cenozoic explosive eruptions that have occurred in this region. In addition, we anticipate that the glaciation and resulting climate variability in high northern latitudes may have influenced their mode of dispersal in the atmospheric and oceanic environment, by fallout, ice-rafting and turbidity currents.
Traimng content (objective, benefit and expected impact)
The collaboration with scientists from GEOMAR should bring a new approach to the study and interpretation of the sources and depositional environments of volcaniclastic sediment that are influenced by climate variability. The results wi]l be critical to the evaluation of global volcanism in the North Atlantic region, and should complement other studies of eolian and deep-sea transport of terrigenous sediments which are underway.
