Dr Sean Pyne-O'Donnell

Geography, ICARUS

Post Doctoral Researcher

Laraghbryan House


Sean has a background studying past climate and environmental change in peatlands, lakes and oceans. He has an interest in proxy indicators of climate change impacts such as testate amoebae in peatlands and accompanying changes in sediment chemistry. He also uses tephrochronology (far-travelled volcanic ash layers; tephra layers) as timelines to precisely link and date palaeoenvironmental changes which are often abrupt and of short duration. Such layers are often well represented in sediments such as Irish peatlands.
He has worked as a postdoc in Singapore, Belfast, Bergen and London. Now at Maynooth University, he works in the ICARUS Climate Research Centre as part of the HoStIr (Holocene Storminess in Ireland) team which seeks to quantify and date impacts of Holocene storminess using palaeorecords preserved in Atlantic coast Irish bogs.
