Deep in the Gulf of Mexico, scientists have discovered an ecosystem in collapse. Two biologists from Temple, professor Erik Cordes and graduate student Andrea Quattrini, recently told "Living on Earth" what they've seen and what it means for aquatic life in the Gulf. Most of the coral colonies attached to the area had either recently died or were dying, explained Quattrini. "Anything that happens in deep water is going to have repercussions in the shallow water and in the wider ecosystem of the Gulf," said Cordes.
