What was the primary objective of the IRONEX experiments?
Test marine pollution effects
Examine deep-sea drilling impact
Track ocean current changes
Probe Martin's iron fertilization theory
Answer
Iron fertilization experiments, exemplified by the IRONEX mission, aimed to investigate oceanographer John Martin's hypothesis. This theory suggests that deliberate enrichment of surface ocean waters with iron could stimulate phytoplankton growth and carbon dioxide consumption, potentially serving as a geoengineering approach to mitigate carbon dioxide levels and combat climate change.
