What Lives in Gulf of Mexico 7 Years Past Deepwater Horizon Explosion?

One surprise in their findings, Murawski said, was that the part of the gulf with the lowest diversity of fish species is the area of the gulf with the greatest number of offshore oil rigs.

“They’ve had 50 to 60 years of oil development there,” he said. “So that may be one of the at-risk areas” in case of a future oil spill. A disaster like Deepwater Horizon could more easily wipe out the fish living there to the point where they could not bounce back, he explained.

Can Seismic Blasts for Oil Open Pandora’s Radioactive Box?

For decades, the U.S. military routinely dumped thousands of tons of obsolete, excess and captured munitions into U.S. coastal waters, thinking the high seas were the best place for the materials to safely decompose. The Atomic Energy Commission likewise oversaw the ocean dumping of untold thousands of drums of low-level radioactive waste from the nation’s manufacturing, research, medical and military sectors.

Combatting Coral Disease in Florida

Around the world, coral reefs are facing trouble. Coral bleaching, due in part to rising ocean temperatures, has stressed reefs, leaving them weakened and susceptible to disease. Now, in Florida, scientists are struggling to combat a mysterious disease that’s threatening the future of the world’s third largest coral reef.

Study: Microplastics on Aquatic Life

“One of the types of organisms that seems to be affected is crustacean zooplankton, which are the main prey for many small fishes,” said Höök, whose findings were published in the journal Science of the Total Environment. “The fact that these very small organisms are consuming these microplastics, altering their growth, reproduction and survival, means there could be consequences up the food web. If zooplankton numbers decline, there may be less food available for organisms at higher trophic levels.”

Coral Reef Death Impacting Sea Levels

In the Florida Keys, the U.S. Virgin Islands and Maui, coral reef degradation has caused sea floor depths to increase as sand and other sea floor materials have eroded over the past few decades, the USGS study found. In the waters around Maui, the sea floor losses amounted to 81 million cubic meters of sand, rock and other material – about what it would take to fill up the Empire State Building 81 times, the researchers calculated.
