| Abstract | Oceanographic observations has been traditionally undertaken using ships but the emergence of autonomous ocean gliders have provided an alternative measurement platform to acquire high spatial and temporal resolution data even during periods of extreme weather conditions. These data sets enable researchers to discover physical processes as well as document the natural variability of the ocean and coastal ecosystems. The Australian Integrated Marine Observation System (IMOS) ocean glider facility has been in operation since 2017 and have completed more than 400 glider missions around Australia with ~40% deployed along the west Australian coast in the eastern Indian Ocean. Discovery of Dense Shelf Water Transport (DSWT), or underwater rivers, where higher density water is transported along the sea bed across the continental shelf around Australia is one of the major scientific highlights. Also time series spanning more than 16 years allows for the documentation of the inter-annual variability in surface and sub-surface ocean parameters (temperature, salinity, chlorophyll etc), particularly through ENSO cycles. |
