CP017
The Transformation and Fate of Carbon at the Land-Ocean Interface and Beyond

Session ID#: 84577

Session Description:
Coastal oceans are important hot spots for the turnover and storage of organic matter at the land-ocean interface. Rapidly evolving analytical capabilities have allowed us to understand that organic matter likely exists along a reactivity continuum that is based on not only its source, but also the ecosystem properties where it currently resides. Yet, carbon cycling in coastal regions as well as transformations of terrestrial organic matter in the ocean and its linkage to marine microbes are still not well understood. In this session, we seek to bring together research that improves our understanding of biogeochemical carbon processing and/or storage in coastal oceans under past, present, and future climate scenarios. We invite contributions from all areas of carbon biogeochemistry that cut across ecosystem boundaries, covering studies from a wide range of spatiotemporal scales and settings. Studies assessing biotic and abiotic drivers changing organic matter composition at the molecular level are welcome. Presentations that examine the mechanisms underlying observed patterns in distribution or rates of particulate and dissolved organic matter transformation, their linkage to nutrient cycling and microbial remineralization processes across aquatic gradients are particularly encouraged.
