Tonight, the plankton feast

Dust-storms are not unknown in some Australian hick-towns like Canberra, Adelaide and Melbourne, but were pretty much unheard of in Sydney in recent years - until today.

Conditions have eased, but it did look pretty freaky outside this morning. The redness of the dust suggests that it is high in iron, which is great news for the phytoplankton and the many organisms that feed on them.
