I would like to draw your attention to a session which we are
organising at this year's Goldschmidt conference on "The
future of biogeochemical cycling in the polar regions". The
will be Jorien Vonk (Vrije Universiteit Amsterdam). Abstract
deadline is 1 April.
"The Polar regions are currently experiencing a period of warming,
resulting in the retreat of glaciers, an increase in the active
layer depth of permafrost and a changing hydrological cycle.
Decreased permafrost cover is expected to increase overall fluxes of
solutes as the active layer deepens. Likewise, solute fluxes from
glaciers are predicted to increase by virtue of the increased
discharge as a result of a longer melt season. As highlighted in the
recent 2016 Arctic Freshwater Synthesis report, the interplay
between hydrology, microbiology and geochemistry in controlling the
flux of inorganic and organic solutes and the downstream impacts on
freshwater ecosystems is uncertain. For example, will changing
environmental conditions (e.g. hydrology) influence the cycling of
metals (e.g., calcium and iron) and carbon (inorganic and organic)
and in turn, the microbial communities which mediate many of the
chemical reactions occurring in these environments? In this session
we invite contributions from geochemistry, hydrochemistry, modelling
and microbiology: essentially from all researchers seeking to
understand biogeochemical cycling in these special environments with
the aim of promoting dialogue between often separate disciplines."
The Goldschmidt conference
will be held in Paris, France, 13-18 August.
We hope to see many of you in Paris!
