Coral Nursery: 
Coral reefs, while crucial to the world, have experienced a large decent in numbers. Anthropogenic factors play the most prominent role in coral population reduction, with latest studies showing 58 to 70% of reefs threatened by direct human contact. As an example, ship grounding have been known to fragmentize and detach vast areas of coral reefs. Adding, as a consequence of natural events such as swells and storms, large coral heads can break off of the reef. In this state, they frequently tumble in the water column, coming to rest in turbid and low-light benthic environments at the edge of the reef where they perish. Freed from the substrate, they may also become projectiles in the surf, causing further damage to other coral colonies.

With populations at risk, it is necessary to not only preserve, but to rehabilitate detached corals at risk of dying. Regardless of the reason a coral becomes detached from the reef, the outcome is usually coral death. There is currently no formal effort to gather and re-attach these corals. Therefore, NOAA has identified a need for an in-water nursery where detached corals can be revived and stored for mass transplantation, using the advantage of economies of scale to achieve impactful and systematic restoration.
