IMOS was showing off a range of marine observing technologies, including Argo autonomous profiling floats.  Argo floats measure ocean temperature and salinity from two kilometres depth to the surface every ten days, transmitting measurements by satellite in near real time.  Each float then repeats this ten day cycle for between four and seven years, building up an amazing record of the sub-surface ocean.

AAL featured a number of projects including the Australian Square Kilometre Array Pathfinder (ASKAP).  ASKAP is a new radio telescope currently being commissioned at the Murchison Radio-astronomy Observatory in Western Australia.   It is part of the international Square Kilometre Array project, which is building the world’s largest and most sensitive radio telescope.
