In recent decades, significant advances have been made in understanding the generation, fates and consequences of water quality pollutants in the Great Barrier Reef ecosystem. However, skepticism and lack of trust in water quality science by farming stakeholders has emerged as a significant challenge. The ongoing failures of both compulsory and particularly voluntary practices to improve land management and reduce diffuse agricultural pollution from the Great Barrier Reef catchment underlines the need for more effective communication of water quality issues at appropriate decision-making scales to landholders.

Article Synopsis
  • Atmospheric carbon dioxide levels and climate changes over geological times are influenced by volcanic outgassing and weathering processes, specifically the breakdown of silicate and organic-carbon rocks.
  • A study presented a 53-million-year record of carbonate accumulation from the equatorial Pacific Ocean, showing that the calcium carbonate compensation depth has increased from approximately 3.0-3.5 km to 4.6 km over time, indicating long-term ocean cooling and increased weathering.
  • The research identified significant fluctuations in the carbonate compensation depth during the middle and late Eocene, attributing these changes to variations in weathering and how organic carbon was delivered to the oceans.
