Six years ago today, the Deepwater Horizon oil rig exploded in the Gulf of Mexico near the Mississippi River Delta. Oil gushed for 87 days, leaking an estimated 210 million gallons into the ocean. Marilyn Weiner and Hal Weiner, directors and producers of the PBS series “Journey to the Planet Earth," talk about their new film “Dispatches from the Gulf,” which looks at the environmental fallout from the disaster. Steve Murawski, a fisheries biologist and marine ecologist who is featured in the documentary, joins the conversation. 

To coincide with the 6th anniversary of the spill, a sneak peek screening of "Dispatches From The Gulf" will be livestreamed on Wednesday, April 20th here at 2 p.m. and 7 p.m. ET.

On April 27th, the film will be available to watch in full on the "Dispatches" YouTube channel.
