Restore ocean life.
Remove carbon.

We design small, carefully monitored Ocean Iron Fertilization (OIF) experiments to boost marine productivity and durably sequester carbon in the deep ocean — science-led, measured, and safe.

What is OIF?

Professor Victor Smetacek explains the basics of Ocean Iron Fertilization in this video.

Phytoplankton & the carbon cycle

Phytoplankton are the ocean’s invisible forests. Through photosynthesis, they absorb CO₂, fuel food webs, and help transfer carbon into the deep ocean — making them a critical part of Earth’s climate system.

Whales & the iron pump

Great whales help recycle iron at the surface. Their feeding and nutrient-rich plumes keep iron bioavailable for phytoplankton, amplifying productivity and linking top predators to microscopic climate work.

Misconceptions, cleared

Professor Victor Smetacek addresses domoic acid headlines and harmful-bloom fears — clarifying how toxin events arise, why iron additions aren’t blunt triggers, and how informed, evidence-based design can restore ocean function without fueling fear.

Ecosystems in motion

Professor Victor Smetacek traces the pathway: diatoms → krill → whales — and back to iron at the surface. He outlines nature-mimicking OIF to help restore biodiversity in the Southern Ocean by reviving the iron cycle that powers this web.
