BN41A:
Land-Sea Connections in the Global Carbon Cycle I


Session ID#: 37664

Session Description:
Understanding biogeochemical transformations, linked microbial processes, and ecosystem productivity across the land-ocean interface is essential for closing gaps in global carbon flux estimates and evaluating how ecosystem functions, such as changes in community composition and phenology, will be affected by future change. In this session, we seek to bring together research that improves our understanding of biogeochemical and microbial processes to better constrain the magnitude and sensitivity of global carbon budgets under past, present, and future climate scenarios. We invite contributions exploring observed and modeled changes from all areas of carbon biogeochemistry that cut across ecosystem boundaries, covering studies from a wide range of latitudinal settings and spatiotemporal scales. Contributions that examine the mechanisms underlying observed patterns in distribution or rates of particulate and dissolved organic matter transformation, their linkage to CO2 outgassing/uptake, and nutrient cycling across the aquatic continuum are particularly encouraged.
