Feature Guest - Chris Kemp

Ambergris is produced by a small proportion of sperm whales, and washes up in smelly, tarry lumps on coastlines. Journalist and molecular biologist Christopher Kemp had never even heard of it until one day a large lump of an unidentified white substance washed up on Breaker Bay in Wellington. So began a journey that has taken Chris across the globe and into contact with some interesting and at times shady characters.
