USS ArizonaResting on the bottom of Pearl Harbor, the USS Arizona Memorial is now a place of healing

and spiritual renewal. While water quality remains an issue, the wreck of the USS Arizona has been reborn as an artificial reef teeming with life.

The USS Arizona sits on top of deep mud. Most of the wreck is covered with about seven inches (~18 cm) of silt, built up from river sediment.

Seven decades later, marine life rejuvenation in Pearl Harbor is represented by the diverse reef community growing on the hull.

The USS Arizona sank with 1.5 million gallons (5.7 million liters) of oil aboard. About 0.5 million gallons (1.9 million liters) remain.

Increased wartime shipping activity accelerated the rate of new marine species introduction, some of which persist and threaten native species.

Corals, sponges, invertebrates, and algae encrust parts of the USS Arizona. Over time, these organisms are colonizing the hull.

Pearl Harbor sediment blankets the hull

Life rebounds, even where disaster struck

Oil continues to seep in small drops from the hull

New marine species are introduced by shipping

Hull deterioration is influenced by marine life

Upland agriculture and development sediment runoff settles on the hull.

Corals, sponges, and small reef fish have made the hull their home.

Oil leaks from the hull still rise to the surface of the water.

This invasive red algae forms huge mounds and thrives where water quality is poor.

Encrusting marine life grow around a portal on the ship’s hull.

pre-1800s

Ke awalau 'o Pu'uloa (Pearl Harbor) was a vast wetland that provided an abundance of seafood. Hawaiian legends say a mo'o (supernatural lizard deity) brought i'a hamau leo,the native pearl oyster, to the area.

Once a site of human devastation, now a haven for marine life.
