Argo Floats - tracking the pulse of world oceans

Argo Floats are mechanical robots that float in the oceans and send important information to satellites. This voyage onboard the RV Tangaroa will have scientists from NIWA, NOAA and CSIRO who will be deploying both 'regular' Argo Floats and a new Deep Argo Float that will descend to 5,500m below the surface.
