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 (https://aslo.org/victoria2018/submission-overview).
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
