One of the five finalists in the “Architecture+Weather” category of Architizer A+ Awards, the Bloom was conceived by Sitbon Architectes of Paris. The large, floating structure would be equipped with aquariums of photoplankton, tiny sea-creatures that play a key role in removing CO2 from the air. The semi-submersible Bloom would be tethered to the ocean floor with a series of cables, and could be moved to ‘dead areas’ of the ocean to help increase the water’s oxygen levels. 

The Bloom would also filter sea water to create drinking water, and its sensitivity to sea vibrations would make it an excellent source of early tsunami warnings.
