28th & 29th of July 2016 at the University of Southampton / National Oceanography Centre, Southampton, UK

 

Welcome

Welcome to the participants of the workshop! I’m very much looking forward to seeing you all in Southampton soon. For further information about accomodation in and travel to Southampton, please click this link. The registration for the workshop is now closed, but if you have any enquiries, please email the workshop organiser, Dr. Maarten van Hardenbroek.

 

Keynote speakers

Prof. Oliver Heiri (University of Bern, Switzerland), Prof. Mat Wooller (Alaska Stable Isotope Facility, University of Alaska Fairbanks), Prof. Melanie Leng (British Geological Survey, Keyworth, UK), Dr. Jessica Whiteside (National Oceanography Centre, Southampton, UK)

Workshop aims

The aim of this workshop is to (1) provide a state-of-the-art overview of latest developments in the field, (2) identify key issues for this emerging field and a way to address these in the next years, and (3) stimulate knowledge exchange, reaching out especially towards early career scientists and scientists from developing countries. A more tangible workshop product will be a review article on this topic in the Journal of Paleolimnology that could be part of a special issue if enough interest exists. We will work on the review and possibly an outline for the special issue during a working session with breakout groups on Friday afternoon.
