"We were of the mind that with studying the in the northern Gulf we weren't getting a full Gulf of Mexico perspective." Geochemist David Hollander is travelling with an international team of scientists aboard a Mexican research vessel. Over the last few years, his team has studied the effects of the 2010 Deepwater Horizon spill. But today, they're looking back at a spill that happened 35 years ago and what they learn on this trip might help them understand the future of the Gulf. Mind Open Media producer David Levin talks to David Hollander, Joel Ortega Ortíz, Isabel Romero, Adriana Gaytán-Caballero, and Travis Washburn about their experiences on the in the southern Gulf of Mexico during the research on the Ixtoc spill.
