|HIGH LATITUDE/COLD CLIMATE DUST EVENTS IN SOUTHERN ICELAND|
|Speaker: Dr Joanna Bullard|
|When: Monday 16th May, 1.00-2.00pm|
|Location: Building E7B T3|
Abstract: Mineral dust aerosols play an important role in the earth-atmosphere-ocean system and can impact soils, regional and global climate, and marine productivity. Most research has concentrated on prominent dust sources in the subtropics however significant dust events also occur in higher latitudes, particularly in proglacial and paraglacial regions. This seminar focuses on dust events in southern Iceland, and their spatial and temporal relationships with climate, sediment supply and glacier dynamics. The impact of these events on air quality, geomorphology and marine systems is also highlighted.
Bio: Jo Bullard is Reader in Aeolian Geomorphology at Loughborough University in the UK. Her research focuses on the geomorphology and sedimentology of dryland environments, and she has conducted field research in southern Africa, Australia, the USA and Europe. She has been awarded the Philip Leverhulme Prize in the field of Earth, Ocean and Atmospheric Sciences and the Gordon Warwick Award of the British Geomorphological Research Group. Her research contributes to an understanding of the response of dryland systems to climate fluctuations and the potential importance of aeolian processes to global biogeochemical cycles.
