CP34A:
Interdisciplinary Approaches for Understanding Coastal Ocean Carbon and Biogeochemical Processes and Budgets V eLightning

Session ID#: 93294

Session Description:
The coastal ocean, including estuaries, tidal wetlands, continental shelf waters, and coastal upwelling regions, is highly productive and plays a role in the global cycles of carbon and other elements that is much larger than its area would indicate. The necessity to understand coastal biogeochemical processes is increasing as human activity creates problems such as eutrophication, harmful algal blooms, and hypoxia. In addition, climate change effects, such as warming, sea-level rise, acidification, and changing streamflow, will interact with these problems in complex ways. Our understanding of the role of these changes in the coastal ocean for a larger context is also hampered as the interaction of coastal regions and shelf seas with the global oceans is often treated as a “boundary condition problem” for the respective fields of study.

We invite observational (in situ and remote sensing), modeling, and theoretical investigations that reduce knowledge gaps and uncertainties in processes and budgets related to inorganic and organic coastal carbon and biogeochemistry. Of particular interest are interdisciplinary investigations that go beyond individual systems and enhance fundamental process understanding that has implications across the coastal ocean. Studies of changes in coastal ocean carbon and biogeochemistry due to climate and anthropogenic are also encouraged.
