This new documentary series, in last week’s initial outing, left me spellbound. I couldn’t believe what I had seen – and in addition to the marvels of life found at the rim of a Galapagos Island volcano, or in the sea deep, deep beneath the island chain, there was the marvel of seeing young scientists traversing these most remote of areas with such commitment and enthusiasm. Watch for all of that, and more, in tonight’s second installment, “Secrets of the Deep.”
