given by Dr. Auriol Rae (Junior Research Fellow in Earth Sciences Trinity College, University of Cambridge) Abstract: 66 Million years ago, a 14 km-diameter meteoroid struck the Earth at approximately 20 km/s. This event had a profound influence on the history of life on Earth - causing the extinction of around 75% of all species […]

given by Prof Bridget Wade (Department of Earth Sciences, University College London) Abstract: Numerous oceanic, climatic, and biotic conditions relating to biogeochemical cycles and environmental change impact the composition and distribution of deep- sea sediments. Utilising the extensive sediment archives of the International Ocean Discovery Program (IODP) and its predecessors, maps of deep-sea sediment type have […]

given by Prof. Peter Scott (Emeritus Professor, Camborne School of Mines, University of Exeter) Abstract: Clay minerals, such as kaolinite, illite and montmorillonite, are the essential components of clays. Their crystals are very small and they have variable amounts of disorder in their structure. They impart a plasticity to clays. Their properties also make them […]
