MARINE PERMACULTURE TO REGENERATE OCEAN PRODUCTIVITY

Today's warmer surface waters limit natural overturning circulation and vertical mixing by increasing density stratification in the upper ocean, particularly in the subtropics, reducing available nutrients for algae, fish habitat, fish feed and forage fish upon which other fish depend.

In order to increase food security, bolster marine ecosystems and export blue carbon, infrastructure associated with Marine Permaculture restores mixed-layer overturning circulation locally, thereby regenerating fish habitat, growing local seaweed species, and cooling surface water to pre-industrial era temperatures, preventing coral bleaching and moderating marine heat waves.

Feeding growing global populations is straining diminished marine ecosystems. These resources need to be protected from overexploitation and climate disruption. Each hectare-scale Marine Permaculture has the potential to grow >3000 tons of seaweed per year, fixing a similar amount of carbon dioxide and providing local adaptive strategies for ocean warming, acidification, coral reefs bleaching protection and counteracting climate change at scale.
