Session 060 - Nitrogen transformation mechanisms at the
sediment-water-interface in aquatic ecosystems over a range of latitudes
With increased regional and global problems resulting from
eutrophication and global warming of coastal environments,
understanding the magnitude and mechanisms of microbial nitrogen
transformations at the sediment-water-interface (SWI) of coastal
ecosystems increases in importance. Nitrogen dynamics depends on
complex interactions among such factors as oxygen status, depth,
temperature, light and hydrodynamic conditions. One factor limiting
this understanding has been the lack of suitable approaches to
collect and analyze samples on the time and space scales needed to
determine mechanisms and rates of these processes and relate them to
conditions present in contrasting environments. This session will
welcome results from mechanistic studies of SWI nitrogen dynamics
from a variety of coastal and/or lake ecosystems over a broad
geographic range, from the tropics to the poles. Presentations that
include results from observational or modeling studies that cover a
range of time and space scales or levels of organization, from genes
to whole ecosystems, are encouraged.
