Dear colleagues,

We are convening a session on "Biogeochemical Transformations Across
Terrestrial – Aquatic Interfaces" at the 2018 ASLO Summer Meeting in
Victoria, BC, Canada. Abstracts are due by February 23rd and can be
submitted through the conference website

SS58: Biogeochemical Transformations Across Terrestrial – Aquatic Interfaces
Conveners: Amanda Spivak (WHOI), David Ho (University of Hawaii)
Coastal ecosystems are among the most biogeochemically reactive environments
because they sit at the interface of terrestrial, freshwater, and marine
habitats. The dynamism of coastal ecosystems reflects interactions between
the ecological, biogeochemical, and physical processes that control rates of
organic matter production, transformations, and export. These processes
occur over a range of spatial and temporal scales to affect local, regional,
and, potentially, global biogeochemical cycles as well as the delivery of
valuable ecosystem services. Our ability to estimate current and future
rates of biogeochemical transformations requires an integrated approach that
crosses traditional ecosystem boundaries and links processes over
microbial-to-landscape scales. This is becoming increasingly important as
ecosystems across terrestrial-aquatic interfaces respond to rising sea
levels and experience more frequent and intense weather events. In this
interdisciplinary session, we invite contributions examining ecological,
biogeochemical, and physical processes that affect organic matter cycling
and fate in tidal wetlands (fresh- and salt- water) and coastal waters. We
welcome experimental, observational, and modeling studies based in the lab
and field that bridge spatial and temporal scales; this includes, but is not
limited to, plant-microbe interactions, vertical and lateral fluxes, redox,
carbon, and nutrient chemistry, transient dynamics, spatial and temporal
heterogeneity, and remote sensing.
Keywords: Biogeochemistry, Carbon, Ecosystem, Estuary, Wetland
