Science-led ocean restoration with careful, measurable climate benefit.
Liquid Trees is a science-led ocean venture restoring the natural role of iron in marine ecosystems. In many regions, nitrate and phosphate are plentiful but growth is capped by iron scarcity. By carefully restoring trace iron where it’s lacking, we aim to regenerate productivity and enable measurable climate benefits.
Iron powers enzymes for photosynthesis, respiration, and N₂ fixation. In HNLC waters (Southern Ocean, EEP, Subarctic Pacific), dissolved iron limits phytoplankton, leaving nutrients unused and export weak. Restoring trace iron lets ecosystems use available nutrients and strengthen the biological carbon pump.
Phytoplankton growth supports zooplankton → forage fish → fisheries. We co-design trials with Pacific Island partners to align with local priorities, build monitoring capacity, and pursue fisheries co-benefits and jobs for native communities.
A fraction of bloom biomass sinks as particulate organic carbon, storing carbon at depth for decades to centuries. Our MRV tracks both primary export (large diatoms) and secondary export (food-web pathways) with conservative accounting and third-party review.
We run small, bounded trials that mimic natural iron inputs, with conservative dosing and strict monitoring. Each trial is designed for learning, safety, and transparency.
We operate under international and national regulations with independent oversight. Trials use food-grade salts at tiny doses, stepwise scaling, and transparent reporting to ensure safety, reversibility, and accountability.
