Goldschmidt is the foremost annual, international conference on geochemistry and related subjects, organised by the Geochemical Society and the European Association of Geochemistry.
The following session is relevant to the OA community:
Title: Physical, biogeochemical and anthropogenic controls on pH of estuarine, coastal and open ocean waters and sediments
Conveners: Wei-Jun Cai, Pierre Regnier, Jack Middelburg, Alfonso Mucci
Theme: Chemistry of the Oceans and Atmosphere
Aquatic pH “reflects the thermodynamic states of all the various
acid-base systems present in the water, particularly the geochemically
important carbon dioxide system and is therefore indicative of the
processes involved in biological production and respiration” (Andrew
Dickson, 1984). Physical mixing of various source waters, biogeochemical
reactions under both natural and anthropogenic forcings as well as
anthropogenic carbon dioxide uptake by the ocean from the atmosphere all
exert substantial influences on the pH of estuarine, coastal and open
ocean waters and sediments. The pH of natural waters often reflects a
close coupling between acid-base and redox reactions in these
environments. The recent focus, by the geochemical community, on ocean
acidification and its impact on marine biota and ecosystems further
highlights the importance of pH and its intimate links to geochemical
processes. This session welcomes all aspect of field and theoretical
studies on the processes and factors controlling pH in natural waters
and sediments as well as advances in the development of pH standards and
analytical methods.
