Device to replant Massachusetts eelgrass in marine biomes

The Landmark School InvenTeam invented a low-cost, automated planting system for eelgrass. Local law requires eelgrass loss mitigation when existing beds are disturbed through human activities. The Landmark system can be used by a seaside homeowner, municipality, or interested party to plant eelgrass, stabilize the ocean bottom, and reduce water turbidity. This innovative system decreases the average planting expense by more than 90%, while helping to recover an economically significant marine biome. The Landmark system incorporates biodegradable mesh and disk that use water currents and tidal action to effectively cover the plant roots in sediment and protect the exposed plants.

With the shift from a weighted wide area bio-mat to smaller weighted disks, the team began to problem solve a system that integrates the bio-disk system within a pre­cast biodegradable weight.

To prevent instant disitegration in the water, the cacium carbonate disks need to be covered by a hard layer.

The trays holding the protoypes (disks) was finally decided to be ultramarine blue. It is related so much to the ocean so, might as well right?
