 \nPostdoctoral  Researcher\, Federal Institute of Hydrology\, Koblenz\, G
 ermany\n\nAnthropogenic perturbation of inland water carbon cycling – ca
 tchers or pitchers?\n\nHuman influence has warmed atmosphere\, ocean and l
 and. In consequence\, ecosystems all over the world are changing. While in
 land waters cover only a small fraction of the total land area\, they are 
 often biogeochemical hotspots\, and play an important role in the global c
 arbon cycle by receiving\, transforming\, storing\, emitting\, and transpo
 rting carbon. As a result of human activities\, the role that inland water
 s play in climate forcing and the global cycling of carbon has undergone s
 ubstantial transitions. Inland waters will continue to change in response 
 to climate\, leading to the drying of lakes in some parts of the world and
  newly appearing lakes in other parts. In addition\, an increasing number 
 of impoundments is being built worldwide\, which can further challenge cli
 mate forcing\, as impoundments accumulate carbon in their sediments and em
 it large amounts of methane to the atmosphere. Drying of lakes might be an
 other potent source of greenhouse gases\, and we yet have little knowledge
  on the evolution of newly appearing lakes from melting ice covers. To ful
 ly understand the changes these ecosystems undergo in the warming world an
 d how we can manage them in response to our changing climate\, we need to 
 better understand their chemical\, biological and physical processes.\n\n\
 n\nShort bio:\nAnnika Linkhorst was born 1987 near Hamburg\, Germany. She 
 studied Environmental Sciences and received her B.Sc. from Leuphana Univer
 sity\, Lüneburg\, in 2010\, and her M.Sc. from ETH Zurich\, Switzerland\,
  in 2014. Her studies were accompanied by research stays in Brazil\, Germa
 ny and Korea\, where she studied the carbon composition in subterranean es
 tuaries. She pursued her Ph.D. at the Limnology department of Uppsala Univ
 ersity\, Sweden\, with extensive field work in Brazil in close collaborati
 on with the Federal University of Juiz de Fora. She defended her Ph.D. the
 sis\, “Greenhouse Gas Dynamics in Tropical Reservoirs: Spatial and Tempo
 ral Dynamics”\, in 2019. During 2020\, she worked on the carbon budget o
 f pristine peatland with the University of Quebec in Montreal\, Canada. Si
 nce 2021\, she has been a Researcher at the Federal Institute of Hydrology
  in Koblenz\, Germany\, studying greenhouse gas dynamics and the mixing an
 d dispersion of water masses in large rivers. Her main research interests 
 lie in understanding how human activities influence inland water greenhous
 e gas dynamics\, where her key expertise is the quantification of methane 
 ebullition in tropical reservoirs\, and its spatio-temporal upscaling. She
  works at the threshold of chemistry\, physics\, biology and geology in wa
 terbodies of different types in different climates.\n\n
