I would like to draw your attention to a session which we are organising
at this year's Goldschmidt conference entitled "Weathering processes in
glaciated and permafrost dominated environments". The keynote speaker
for this session is Martyn Tranter (Bristol University).
Climate models predict that warming will be most severe in the Arctic,
where positive feedbacks can potentially amplify the global trend.
Observations suggest warming-induced changes in the Arctic may already
be underway. Examples include accelerated glacial retreat, enhanced
permafrost thaw, increased freshwater runoff, and alterations of
subsurface water flowpaths. These and other changes will impact the
rates and mechanisms of inorganically- and organically-mediated chemical
weathering phenomena, yet high-latitude regions are often
underrepresented in weathering studies. Establishing the response of
weathering to Arctic climate change requires a strong interdisciplinary
approach. In this session, we invite contributions from researchers
seeking to understand cold regions chemical weathering processes at
timescales ranging from the geological to human. Areas of interest
include (but are not limited to) field, laboratory, and theoretical
studies involving radiogenic and stable isotope geochemistry,
hydrogeochemistry, geomicrobiology and ice-ocean interactions.
The Goldschmidt conference is in Florence, Italy, 25-30 August.
The abstract deadline is 12 April and abstracts will be published in the
We hope that you will consider submitting an abstract to this session.
