Poop With 10 Million Times More Iron
Nicols' team analyzed 27 fecal samples from four species of baleen whales, reported New Scientist. "He found that on average whale faeces had 10 million times as much iron as Antarctic seawater." Basically, that's iron concentrate. And strategically emitted – which would have to be up near the ocean surface, where the sun shines — that extra iron would create blooms of phytoplankton, which would then be eaten by krill, leading to a boost in the krill population, leading to ... yes ... bigger whale dinners!
