Advancing Our Knowledge of Land-Sea Connections in the Global Carbon Cycle

Session ID#: 255016

Session Description:
The global carbon cycle remains insufficiently characterized, particularly in coastal and nearshore regions. This lack of insight has hindered our ability to comprehensively understand the role of organic matter transformations across the land-ocean interface in the global carbon budget. In this session, we aim to bring together research that deepens our insight into biogeochemical processes to better constrain the global carbon budget under past, present, and future climate scenarios. We invite contributions from all areas of carbon biogeochemistry that cross ecosystem boundaries, including studies conducted across diverse latitudes and spatiotemporal scales. We especially encourage submissions that investigate the biotic and abiotic mechanisms underlying observed patterns in the distribution or transformation rates of particulate and dissolved organic matter, their connections to CO₂ outgassing or uptake, and nutrient cycling across aquatic gradients.
