Sculptor Jason deCaires Taylor is internationally acclaimed for his underwater installations. Mixing art and science, his works are designed to act as artificial reefs — attracting corals, increasing marine biomass and aggregating fish species — while crucially diverting tourists away from fragile natural reefs and thus providing space for natural rejuvenation.

In 2006 Taylor created the world's first underwater sculpture park off the coast of Grenada in the West Indies. Today Taylor's works are installed in oceans off the coasts of Mexico, Granada and the Bahamas. 

He has said he uses sculpture "as a means of conveying hope and awareness of the plight of our oceans."

Taylor's sculptures change over time, as marine life assimilates the figures. Underneath such changing life forms, the sculptures themselves indicate what is lost or forgotten.

The Lost Correspondent (2006) is one such installation. Immersed at a depth of 8 meters in Grenada, a man sits at his desk, his hands hovering over the typewriter, poised in eternal deliberation. He is a forgotten relic, like his typewriter — an antique, superseded by modern technology.

Taylor’s most ambitious work to date, The Silent Evolution (2012), forms a permanent artificial reef in Mexico.

Occupying an area of over 420 square meters and with a total weight of over 200 tons, it consists of 400 life-size casts of individuals taken from a broad cross-section of humanity.

Here, The Silent Evolution is shown being installed. Sculptures are grouped into modules to increase the speed and safety of installation.

Once the module hits the seafloor it is slowly moved into position. 

The sculptures are made with carefully researched environmentally-friendly materials which actively promote coral growth, with inert Ph neutral properties designed to last hundreds of years.

The mirror-finished piano in The Musician (2011) is based on an actual-size replica of a Steinway Concert Grand.

The sculpture, located in Musha Cay, Bahamas, also incorporates spaces that are designed to encourage habitation by marine species. A small hermit crab can be seen crawling across the keys.

The Bankers (2011) symbolize denial: a resistance to acknowledge our looming environmental crisis, and the shortsighted actions of banking and government institutions.

The installation is located in Manchones Reef, Mexico. The buttocks provide an internal living space for crustaceans and juvenile fish. 

Vicissitudes (2007), has had plenty of time to accrete marine life.

Installed at a depth of 5 meters in Molinere, Grenada, the sculpture consists of a ring of 26 children holding hands. Taylor cast the life-size figures from local children.
