We invite you to submit abstracts for the following AGU session (submission deadline August 5th).
BO14: Biogeochemical hotspots across terrestrial-aquatic ecotones Session ID#: 8559 Session Description: The interface between terrestrial, freshwater, and marine ecosystems are dynamic zones of biogeochemical cycling, and often represent hotspots of biogeochemical activity and productivity. This session will highlight studies of biogeochemical cycling across terrestrial-freshwater-marine linkages, from the hyporheic zone to the coastal margin. We welcome presentations that focus on the integration of nutrient and energy cycling across components of the terrestrial-freshwater-marine continuum. We seek modeling and field-based presentations that quantify biogeochemical concentrations (e.g. C, N, P) and fluxes, measure DOM quality, and describe microbial community dynamics over various time scales. We also welcome studies tracking the incorporation of terrestrial C and nutrient subsidies into freshwater and marine food webs, integrative presentations that provide models for cross-disciplinary studies, and overviews of novel science applications in this realm.
