Episode Details

Researchers embark on a three-week mission in Hawkes Bay, New Zealand, to study the potential of boosting ocean alkalinity as a natural solution to combat climate change. The project, led by Earth Sciences New Zealand, aims to map water chemistry around river mouths and track how rivers flush alkaline sediments and groundwater into coastal waters. The mission, part of a five-year, eleven million dollar project, will measure pH, CO2, salinity, and effects on marine life from river plumes. The study will also explore the use of natural algal blooms and forestry wood debris for ocean fertilization and deep-sea carbon storage. The research will help answer key questions on risks, ecosystem impacts, verification, and regulations before any large-scale rollout.
