We would like to invite our colleagues conducting research on any aspect of dissolved organic matter dynamics in watersheds to submit abstracts for Session B02 at the Fall American Geophysical Union meeting in San Francisco, 14-18 December, 2009. We hope that this session will attract a diversity of presentations, in terms of research approach, scales of focus, and geography.
B02: Dynamics of Dissolved Organic Matter in Watersheds DOM transport from terrestrial to aquatic environments is a fundamental component of the global carbon cycle. In both terrestrial and aquatic ecosystems DOM plays a critical role by affecting nutrient cycling, metals mobility and toxicity, heterotrophic production, and drinking water quality. A comprehensive understanding of DOM dynamics in watersheds remains challenging due to complex interactions of hydrological, geochemical, and biological processes. This session invites contributions investigating the sources, transport and transformations of DOM throughout the terrestrial-aquatic continuum. Presentations are encouraged on all aspects of DOM dynamics, ranging from field and laboratory studies to modeling approaches. Example topics might include: 1) watershed approaches identifying spatial or temporal variations of DOM export and composition; 2) descriptive or experimental studies identifying the factors controlling the fluxes and composition of DOM in soils and/or aquatic systems; 3) novel analytical techniques for quantifying various DOM sources and transformation pathways (isotopic, spectral, chemical, or physical methods for detailed characterization of DOM constituents); 4) modeling approaches addressing DOM dynamics in terrestrial and aquatic environments. http://www.agu.org/meetings/fm09/program/scientific_session_search.php?show=detail&sessid=63 Abstract Submission The deadline to submit an abstract is 03 September 2009 2359 Eastern Daylight Time.
