Tephra constrains natural and anthropogenic changes in Icelandic lakes - with Wesley R. Farnsworth

Iceland is an ideal setting to investigate naturally occurring shifts in climate and environment due it sensitive location, the geochronological potential of tephra and its human-free Holocene (following the documented settlement c. 871 AD). This investigation is based on a strategic network of tephrochronologically constrained lake records from around Iceland which span the Late Glacial and Holocene. The aims of this project are twofold: i) to better understand the glacial and volcanic history of Iceland following its dynamic deglaciation during the Late Glacial –Early Holocene and ii) investigate the impact of explosive volcanism, humans and land-use on the pristine natural environment. While these lake records are high resolution multiproxy recorders of natural and anthropogenic shifts through the last 14 ka BP, the application of environmental DNA on the sediment sequences allows for an unprecedented understanding of species migration, vegetation establishment / resilience, as well as human impact and land-use. Wesley R. Farnsworth is from the northeastern US but has spent a decade residing in Svalbard contributing to extensive field experience in a wide range of geoscience. Farnsworth has a background in glacial geology, periglacial landscapes and slope processes with an emphasis in Quaternary mapping. Prior to starting a Carlsberg funded post-doc within the ROCS Research Centre on Oceans Climate and Society, Farnsworth and his family have been based in Iceland for two years. During this time Farnsworth was investigating the distal deposition of tephra within the North Atlantic as a NordVULK Fellow. Farnsworth continues to develop pedagogy skills with experience as a field instructor and lecturer at the University of Iceland and University Centre in Svalbard. --------------------------------------------------------------------------------------------------------- The ROCS lecture series invite leading scholars across disciplines to discuss research on diverse topics involving ocean, climate, and society. The aim of the series is to provide an interdisciplinary platform for multiple layers of similar concerns and explore the interconnections that emerge when topics on ocean, climate, and society are brought into critical proximity with one another. ROCS is a transdisciplinary centre that applies innovative technologies and analysis that, for the first time, enables descriptions of entire ecosystems in relation to climate development through historical time and the heritages of human societies. The overarching aim is to elucidate how human-ecosystem-climate relationships shape past, present, and future worlds.

ROCS is supported by the Carlsberg Foundation, the Icelandic State and Rannís.
