Coral reef
On 17 May 2018, a Coral Aquaculture project was jointly launched by JTC Corporation and NParks to support Singapore's Year of Climate Action 2018 and aid with coral reef restoration. The project involved the creation of 500 squares metres of artificial reef area using concrete structures to support existing ecosynthesis and Coral reef protection efforts to conserve marine biodiversity. In November 2018, the first of eight structures was lowered to the sea floor. The 10 metre tall structures, which stay on the seabed using their own weight, are made with concrete and fiberglass, and have a rough surface made with recycled rocks which allows organisms such as barnacles and shellfish to attach to the structure.
