Bikini Atoll, formed over millions of years around an island in the Pacific Ocean about halfway between Papua New Guinea and Hawaii, has been subjected to horrific human-caused disturbances. Between...
This specimen of the deep-sea coral Desmophyllum dianthus shows the visible bands that help marine scientists learn how ocean conditions changed over time. By looking at the thickness of each band,...
