Overview

Analysis reveals increased organic carbon oxidation during the Toarcian Anoxic Event, suggesting a feedback on climate warming.

Key Points

  • The research aims to understand how organic carbon oxidation rates changed during the Toarcian Ocean Anoxic Event based on rhenium isotope measurements.
  • Measured rhenium isotope composition (δ 187 Re) in Early Jurassic marine sediments.
  • Used mass balance modeling to assess changes in organic carbon oxidation rates.
  • Analyzed geological data to correlate with global temperature increases during the T-OAE.
  • Observed a 0.22 ± 0.10‰ decrease in δ 187 Re values during the Toarcian Anoxic Event.
  • Increased weathering intensity linked to global warming of 6–7 °C.
  • Estimated potential delivery of 7600–20,490 PgC to oceans and atmosphere.
