Coral and the Bomb

This poster showcases the correlative relationship between the nuclear bombs testing of the mid-late 1900's and the radiocarbon d14C levels present within ocean coral in two recorded locations of the Indian Ocean: Penang Island, Sumatra and Watamu Reef, Kenya.

 

The values of radiocarbon shown in the top section of the visualization change from depleted negative levels to high and sustained positive levels as bomb testing dramatically increased in the 60's. The aqua circles communicate the quantity of bombs tested each year. Finally, the blue descending bars show the accumulated amount of nuclear bombs detonated to demonstrate that the effects of each test layers on to the next and grows over time.
