20 years of animal-borne ocean observing by the IMOS Animal Tagging Facility
For two decades, the IMOS Animal Tagging Facility has equipped seals and sea turtles with ocean sensors to collect temperature, salinity and depth data from the Southern Ocean to the tropics. With more than 1,100 tagged animals generating over 440,000 ocean profiles filling major gaps in remote ocean observation. These animal-borne sensors improve our understanding…

New season of turtle tracking helping to understand the sub-surface waters of Northern Australia
IMOS is providing valuable oceanographic measurements in this poorly sampled region whilst simultaneously delivering information about turtle behaviour and movements by attaching satellite tags to turtles. On a recent field trip satellite tags were attached to 20 olive ridley turtles during the nesting season at Imalu Beach on Melville Island, which is in the Tiwi…
