Bioblitz refers to an intense period of biological surveying in an attempt to record all the living species within a designated area. Typically conducted on terrestrial habitats, the community (scientists, naturalists and volunteers) conducts an intensive field study over a continuous time period together.

As part of Singapore Citizen Science program, a Marine Bioblitz program was initiated, starting at the Sisters Islands Marine Park. Volunteer teams will be led by domain scientists to survey reef areas to document the biodiversity observed there. This program will be expanded to key reef areas in Singapore.
