So, the article could really do a better job here, but it is a known fact that nutrient bottlenecks in phytoplankton reduction can be very efficiently solved when "upwelling" occurring bringing the minerals to the upper layers. I can certainly imagine a similarly efficient process which relies on whale waste to provide these nutrients, this is called a "whale pump" in the article. Would love to see better reference on this!
