Blue carbon

Blue carbon research focuses on the ways that oceans and vegetated coastal ecosystems, like mangroves, tidal marshes and seagrass beds, contribute to the global carbon budget. 

There are people working on Blue Carbon right across PML’s scientific disciplines. We do extensive research in this area, including everything from using remote sensing approaches to gathering data and developing detailed understandings of the biogeochemistry, through to understanding the biodiversity implications and modelling, and also valuing changes in carbon budgets and researching the societal implications.

A key area of activity for PML’s blue carbon research is how carbon flows between different ocean carbon pools and the pathways it takes to sites where long term sequestration takes place, especially between the coast and the open ocean. PML has been a leading institutions in the development of the understanding about the role of macroalgae in global blue carbon, informing conservation and restoration of macroalgal habitats, as well the growing seaweed farming industry. Our researchers are involved in a number of international initiatives currently developing the knowledge necessary to pave a more inclusive definition for blue carbon ecosystems (including macroalgae and other types of habitats) as well as developing policies that capitalise more broadly on global blue carbon capability toward climate change mitigation.
