The Integrated Marine Observing System is an array of connected technologies developed by Australian climate and ocean scientists to monitor nearly one-third of the world’s oceans. The network, which got its start in 2007 with initial funding of more than $90M from government and partners, takes measurements of physical, chemical and biological variables. The system employs sensor floats, autonomous underwater vehicles, sensor tagged animals, moored scientific stations and satellite remote sensing to gather a variety of real-time information such as water temperature and salinity, and study their effects on marine health.
All data collected by IMOS is available for free online via the IMOS Ocean Portal.
