Lecture on November 7th: “Walking” Among Underwater Landslide Scars by Dr. Aggeliki ‘Aggie’ Georgiopoulou (UCD)
7 November, 2018 @ 5:30 PM - 7:30 PM GMT
Abstract: Tsunamis can be caused by movements of large portions of submerged slopes, and geologists are now realising that underwater landslides are more common than once thought. Until now, we have been studying slope failures from research ships at the sea surface, several hundreds of metres above the landslide scarps themselves. Wouldn’t it be better if we were able to walk up to a landslide scarp and study it the way we study a landslide on land? With the advent of deep-sea robots (remotely operated vehicles (ROVs)) that are equipped with high-definition cameras and robotic arms for sampling, we can now access and sample deep-sea scarps in ways never before considered. ‘Walking’ among underwater landslide scars is becoming a reality.
Biography (in Dr. Aggeliki ‘Aggie’ Georgiopoulou’s words) : I am a marine geologist. I’m from Patras in Southwest Greece, where I also studied for my geology degree. I then left Greece and obtained a MSc in oceanography from Southampton University (England), where I also completed my PhD in underwater landslides. I then spent 3 years at Cardiff University (Wales) as part of an industry-funded consortium working on data from the Nile deep-sea fan. In 2009, I joined UCD, first as a Griffith Research Fellow but then, since 2013, as a lecturer in sedimentology. I’ve recently come back from the US where I spent 5 months at the US Geological Survey in Woods Hole (Massachussetts) with my Fulbright–GSI scholarship, working on video data from underwater landslides in offshore USA and Puerto Rico.
