Award-winning US photographer Stephen Mallon has captured this series of pictures over three years to document the unusual methods that New York City uses to dispose of its subway cars.



With their working life complete, the subway cars are loaded onto barges and are taken out into the Atlantic Ocean.




There they are dropped into the water using construction equipment. Once settled on the sea floor they will gradually become covered in coral, forming artificial reefs.

The image "Don't do this" will be featured along with other work by Mallon in the solo exhibition "Patterns of Interest" at NYU’s Kimmel Galleries from 6 February to 15 March.
