Collaboration publishes landmark blue carbon study

ANSTO environmental scientists contribute to investigation of carbon capture in wetlands.

ANSTO has contributed to collaborative research published by the University of Wollongong in the prestigious journal Nature that shows that tidal marshes could help mitigate the impact of climate change.

Associate Professor Kerrylee Rogers led a large team of researchers from University of Wollongong (UOW); Macquarie UniversitySmithsonian Environmental Research Center, USA; Nelson Mandela University, South Africa; Yunnan University, China; and ANSTO.

The findings of research team who analysed carbon stored in more than 300 salt marshes across six continents were being reported widely in the media.

Environmental scientist Dr Debashish Mazumder undertook out stable isotope analysis and radiochemist Atun Zawadzki used several nuclear techniques to determine the rates of sediment accumulation using radioactive isotopes. Both are co-authors on the paper. 

Mazumder said stable isotopes of carbon and nitrogen in conjunction with elemental carbon and nitrogen found in the sediment was used to calculate carbon sequestration capacity in coastal wetlands and sources.

“ANSTO has many decades of experience using isotopic analysis to determine the source and fate of carbon, reconstruct past climate and environmental conditions, investigate, food web analyses in aquatic ecosystems and other applications,” said Mazumder.
