Vegetated coastal ecosystems in the Southwestern Atlantic Ocean are an unexploited opportunity for climate change mitigation

V. Hatje, M. Copertino, et al.

This paper reveals groundbreaking insights into organic carbon storage in the Central and Southwestern Atlantic coastal ecosystems, emphasizing the critical role of mangroves in carbon accumulation. With an estimated 0.4 Pg of organic carbon stored and a significant annual accumulation, this research underscores the urgent need for conservation efforts in these vital ecosystems. This significant study was conducted by Vanessa Hatje, Margareth Copertino, Vinicius F. Patire, Ximena Ovando, Josiah Ogbuka, Beverly J. Johnson, Hilary Kennedy, Pere Masque, and Joel C. Creed.

Abstract
This paper systematically reviews organic carbon storage and accumulation rates in vegetated coastal ecosystems (mangroves, seagrasses, and saltmarshes) across the Central and Southwestern Atlantic. It estimates that 0.4 Pg of organic carbon is stored in the region, accumulating 0.5 to 3.9 Tg carbon annually. Mangroves dominate, contributing 70-80% of annual accumulation. The findings highlight the importance of conserving these ecosystems for climate change mitigation.
