Sitting at a restaurant famous for its views overlooking the Eiffel Tower in Paris, I was 200 meters (656 feet) above sea level talking with biologist David Wachenfeld through a headset in his full-face breathing mask while he scuba dove 4-meters (13-feet) deep around Australia's Great Barrier Reef.
Since my job gives me the opportunity to live anywhere, and I choose to live in France, this was one of those "God, I love my job" moments. Wachenfeld, who was born in Paris, made the case that for him it was as well.
Our conversation was streamed live on Youtube and on a Google+Hangout during part of Reef Live, a 12-hour interactive exploration of the Great Barrier Reef.

Wachenfeld explained to me the importance of coral spawning events that happen a few days after the full moon in October, November and December. That's when whale sharks, not quite as big as blue whales, but impressive in size and appearance none-the-less, cruise the surface waters of the Great Barrier Reef gorging on the floating, microscopic array of reproductive coral fury.
