The “dead zone” of the Gulf of Mexico

Ocean expert Nancy Rabalais tracks the ominously named “dead zone” in the Gulf of Mexico — where there isn’t enough oxygen in the water to support life. The Gulf has the second largest dead zone in the world; on top of killing fish and crustaceans, it’s also killing fisheries in these waters. Rabalais tells us about what’s causing it — and how we can reverse its harmful effects and restore one of America’s natural treasures.

This talk was presented at an official TED conference, and was featured by editors on the TED home page.


Diving the Deadzone, Part 1

Diving at station C6C in the northern Gulf of Mexico, south of Terrebonne Bay. This station is in the heart of the “dead zone”- a region of seasonally hypoxic bottom water that can span tens of thousands of square kilometers. The dive demonstrates the beautiful green water of the upper water column, shimmering water created by the halo cline, and the murky, low visibility hypoxic zone of bottom water. Shot by yours truly with a GoPro Hero4 as part of the CBS News feature on the region. First of three parts.


CBS This Morning – Massive dead zone in Gulf of Mexico

The largest dead zone ever recorded in the U.S. has appeared in the Gulf of Mexico. It is primarily caused by fertilizer and sewage runoff that eventually forces marine life to leave — or suffocate and die. Jeff Glor reports.
