Researchers have found that the iron released by melting ice in West Antarctica isn’t in a form that benefits marine life. That may spell trouble for the ocean’s ability to absorb carbon pollution.
What’s happening?
According to ScienceDaily, the study found that iron released by melting ice in West Antarctica is not suitable for marine life. This change is significant because iron’s usual role in the ocean is to support algae growth, which is vital for absorbing carbon pollution.
The researchers believe that the chemical properties of the iron-rich sediment are responsible. Extreme weathering likely altered the iron, making it hard for the algae to use to support growth, ScienceDaily explained.
Due to this change, the continued loss of ice could mean less algae, which may…
