Overview

Analysis contrasts organic matter sources and carbon stocks in two semiarid mangroves, highlighting implications for carbon storage stability.

Key Points

  • This research aims to compare organic matter signatures and carbon stocks in two semiarid mangroves to assess their carbon storage capabilities.
  • Analyzed sediment cores for granulometry, organic matter, carbon, and nitrogen content.
  • Used UV–Vis and 3D fluorescence spectroscopy for characterization of organic matter.
  • Conducted Rock-Eval pyrolysis for further analysis of organic matter stability and characteristics.
  • Pacoti mangrove shows higher carbon content (2.16%) and stable carbon stocks compared to Jaguaribe (1.2%).
  • Pacoti has a C/N ratio of 21.75, indicating richer autochthonous organic matter, whereas Jaguaribe’s is 15.1, suggesting carbon depletion.
  • Carbon storage in Pacoti is up to five times greater than in Jaguaribe, highlighting its effectiveness as a carbon sink.
