Abstract

WHALES aremajestic. And their poo is of monumental importance. A study involving University of Tasmania students has found that the iron in whale poo has a fertilising effect on phytoplankton, which are crucial to removing carbon dioxide from the atmosphere. University of Tasmania marine biogeochemistry PhD candidate Lavenia Ratnarajah said increasing whale populations would increase the low levels of iron in the world’s oceans, which in turn would increase phytoplankton to remove greater amounts of carbon, and maintain eco-system health.
