Oasis: 3D Printable Artificial Reef System to Combat Coastal Whitening Events

Abstract

This research seeks to implement a 3D printable artificial reef design to restore the ecosystem degraded by coastal whitening events. Coastal whitening events refer to a phenomena where a coastal ecosystem experiences decline in biomass and diversity due to calcium carbonate in seawater destroying the habitat of seaweeds. Worldwide, coastal whitening events are increasingly becoming problematic, not only yielding disastrous impacts to the ecosystems but also to the economy of the seaside communities.

This research seeks to design, 3D-print, and deploy an artificial reef made out of biodegradable resin and iron sulfate to encourage the growth of seaweed. Presently, I have 3D modelled my prototype design of the pot on Sketchup. Next, I will test the prototype design against coastal conditions via an online CFD program and use the feedback to modify the design appropriately. The finalized model will be printed via a 3D printing firm. The model will be plated with seaweed and shellfish and deployed near aquaculture.

Project Oasis Artificial Reef Design prototype #6

This is the 6th prototype, an evolution of the original patented form. It features a curved design, replacing the rectangular shape of the original. The thinner wall thickness allows for more economical use of lighter materials and increased structural strength, while providing a more suitable surface for the movement of shellfish. This is 3D printed with biodegradable material.
