Going out (to sea) with a bang: Biogeochemical cycling and intersections with ecology as rivers traverse through deltas, estuaries, and river plumes
Session ID#: 82722
Session Description:
While the river continuum concept is now deeply embedded in our thinking about watershed biogeochemistry, we need to extend this concept to include the journey of river water through deltas, estuaries, and river plumes. This session will focus on patterns and processes between the head of tide and the open ocean that are both driven by and serve to alter river-borne constituents, including the myriad of biogeochemical changes that occur as river waters slow down, spread out, encounter wetlands and salinity, drop sediments and enable photo-oxidation, interact with invasive species and human disturbance, undergo tidal pumping with local landscapes, fix/release carbon, consume nutrients while stoking algal blooms, undergo flocculation, sorption and desorption, fuel food webs, (and more). We invite presentations that explore all the ways that biogeochemical cycling drives ecology and ecology drives biogeochemical cycling in the delta/estuarine/plume environment, with whatever tools it takes to get the job done.
