Understanding carbon flows in vulnerable coastal wetlands
A new research network aims to accelerate discoveries in the science of these important natural carbon sources and sinks.
Coastal wetlands provide protection from wind and waves, support habitats and fisheries, and store large amounts of atmospheric carbon dioxide for centuries to millennia. These ecosystems can also be sources of greenhouse gas emissions to the atmosphere; wetlands that do not have the capacity to keep pace with sea-level rise, for example, can erode and release soil carbon rapidly to the atmosphere. Freshwater and brackish wetlands also emit methane, a more potent greenhouse gas over its atmospheric lifetime than carbon dioxide. High
The NSF-funded Coastal Carbon Research Coordination Network (CCRCN) was established in 2017 with the goal of building a global community of scientists, policy makers, and non-governmental organizations working to reduce uncertainties and accelerates advances in
