In 2012, a group released nearly 100 tonnes of iron sulphate into the Pacific off Canada, triggering an unauthorised ocean-fertilisation experiment visible from space

An experiment in 2012 released iron sulphate into the Pacific Ocean to stimulate phytoplankton growth. Satellites observed a vast bloom, prompting criticism from researchers and regulators. Scientists noted limited iron incorporation into phytoplankton despite the bloom's intensity. The project aimed to restore ocean pastures and boost salmon populations. This event became a defining example for marine carbon removal technology regulation.
