Ocean treasures, old and new

Is ambergris whale vomit or whale poo? We find out in Naked Oceans
this month as we dive into ocean treasures, old and new. Last month
we explored some of the ways we pollute the oceans by using them as
a dumping ground for too much rubbish. And in this episode we look
at the variety of things we've taken out of the ocean, from prized
perfumes to inspiration for new medicines. Christopher Kemp tells
us all about the mysterious stuff, ambergris - the subject of his
new book. And at Scripps Institute of Oceanography, we call in on
some researchers who are putting glowing critters to good use. And
in Critter of the Month, Emmett Duffy tell us, if he was a marine
creature, which one he'd be and why. For information regarding your
