According to a new study by the University of Hawai‘i at Mānoa, iron particles released by the coal and steel industries are significantly altering the marine ecosystems of the northern Pacific Ocean. These iron deposits fuel excessive phytoplankton growth, which affects oxygen levels and disrupts food chains.
Regions such as Australia, Indonesia, and California are experiencing measurable ecological impacts due to iron dust traveling long distances through wind and ocean currents. These changes influence fisheries, biodiversity, and long-term ocean health.
Lead researcher Dr. Stephanie Wilson noted, "The industrial iron is acting like a fertilizer, but it’s not always beneficial. It creates blooms that die off and consume oxygen, threatening marine life."
Key Findings:
- Industrial iron enters the ocean via atmospheric dust and direct discharge.
- Increased iron concentrations promote harmful algal blooms.
- Marine food webs are being disrupted in multiple regions.
Impacted Regions:
- Australia (East Coast): Algal bloom spikes affecting reef fish.
- Indonesia: Deoxygenated coastal waters harming fisheries.
- California: Changes in plankton distribution and salmon behavior.
The study urges international cooperation to monitor and regulate airborne industrial pollutants that reach marine environments. It also highlights the need for sustainable industry practices to protect ocean health.
