20. Unaffected by fluctuations in water levels Versatility - simple, passive to active, dynamic Zero-to-low power consumption Solar, wind Small footprint Deep water applications Intensified results Modular – add more as needed Additional values - habitat, aesthetic, economic Aggressive aeration capability Temperature homogenization De-stratification ability

23. The Sequestration Pathways

24. The Sequestration Pathways - upward Carbon is sequestered in terrestrial plant growth on top of the islands

25. The Sequestration Pathways - upward Here you see gas coming off biofilm in a Leviathan runway

26. The Sequestration Pathways - downward Carbon is sequestered in organic debris accumulating below the islands

27. The Sequestration Pathways - inward Carbon is sequestered in roots and microbes growing within the islands

28. The Sequestration Pathways – outward – Floating Supermarket effect Carbon is sequestered in the organisms that benefit from the islands

37. “The aeration system is a coiled tube that forms a disk and air is pumped into the tubes.  The small bubbles emitted from the disks aerate the lake and cause an upward draft to mix the lake.  This helped but still was not enough.  This spring they installed six 250 foot Floating Islands and it is believed that the combination of aeration, mixing and habitat for zooplankton is what has made a huge difference for managing the algal blooms”.
