DESCRIPTION:Jérôme Kaiser\, Leibniz Institute for Baltic Sea Research\nL
 ecture series in Urban Demography organized by the URBDEMO LAB EPFL-ENAC-I
 A\n\nThe Urban Demography Lab at EPFL has the pleasure to invite you to a 
 series of six open conferences on population dynamics and urban change in 
 Switzerland and globally.\n\nLecture 4: “Population growth and the begin
 ning of the Anthropocene as registered in Baltic Sea sediments”\nPresent
 er: Jérôme Kaiser\, Leibniz Institute for Baltic Sea Research\n\nAbstrac
 t: The Baltic Sea is a marginal sea under strong anthropogenic pressure wi
 th over 85 million people living in its bordering countries. Due to the di
 scharge of agricultural fertilizers and wastewaters by rivers\, the Baltic
  Sea turned to be a so-called “dead zone” (absence of oxygen at depth)
  since the early 1950s. Direct observations since the 1970s allow understa
 nding the evolution of the Baltic Sea until the present day. Only physico-
 chemical characteristics of sediments accumulating in the deep basins of t
 he Baltic Sea can be used to reconstruct and understand changes in the env
 ironment beyond observations. In this talk\, the methods used to recover a
 nd analyse Baltic Sea sediments will first be introduced shortly. Then\, i
 t will be shown how organic molecules (lipids) derived from faecal matter 
 and preserved in the sediments reflect the history of human population gro
 wth in the Baltic Sea Eastern European countries since 1860. Finally\, the
  proposal of using Baltic Sea sediments as global reference to define the 
 Anthropocene as a new geological epoch will be presented.\n\nShort biograp
 hy: Jérôme Kaiser obtained his PhD degree in natural sciences at the Uni
 versity of Bremen (Germany) in 2006. As a PhD student and postdoc\, he vis
 ited renowned scientific institutes including the Woods Hole Oceanographic
  Institution (WHOI\, MA\, USA)\, the Royal Netherlands Institute for Sea R
 esearch (NIOZ\, Holland)\, the California Institute of Technology (Caltech
 \, CA\, USA)\, and the Pierre and Marie Curie University (LOCEAN\, Paris V
 I). In 2010\, Kaiser joined the Leibniz Institute for Baltic Sea Research 
 (IOW) in Rostock-Warnemünde (Germany)\, where he installed and since then
  runs a laboratory for the analysis of molecular biomarkers. As a sediment
 ologist and paleoclimatologist\, he specializes in the development of mole
 cular organic proxies and their application in sediment cores from lake\, 
 fjord\, and marine systems. The aim of his work is to reconstruct the clim
 ate of the past to estimate future climate changes.\n\n
