It was the whales’ singing that gave them away.
A research team has used coral records to reconstruct the variability of the Indian Ocean Dipole – a big player in the severe drought and record hot temperatures last year – over the last millennium.
When a positive Indian Ocean dipole is coupled with an El Niño event, rainfall decreases dramatically across Australia, and such an event could be on the way, write Agus Santoso and Wenju Cai.
Scientists on a UNSW-led expedition to study microbes in the Indian Ocean have weathered huge seas, encountered giant whales and collected lots of data during the first leg of their voyage from South Africa to Mauritius.
UNSW scientist and national sailing champion, Dr Federico Lauro, is leading a scientific expedition to sample the waters of the Indian Ocean.
A state-of-the-art ocean model has been used to conduct the first detailed investigation of oceanic water flow between the Pacific and Indian Oceans.
In a surprise finding, research led by UNSW scientists has revealed the causes of south-eastern Australia's most severe droughts originate far away in the Indian Ocean.
