Oceanography


Oceanographic data will be collected by gliders from the Integrated Marine Observing System's (IMOS) Australian National Facility for Ocean Glinders (ANFOG).

The Great Australian Bight hosts a unique ecosystem including whales, tuna, sharks and seals that depend crucially on the oceanic currents that upwell nutrients.

Bounded to the south by the Southern Ocean, the Great Australian Bight is a largely unexplored body of ocean.

Active ocean currents and large, storm driven swells can have a direct impact on ocean circulation, which in turn affects marine ecology and biodiversity.

Researchers from SARDI and CSIRO will develop 'hindcasts' of ocean circulation in the Great Australian Bight to investigate the 600m deep Flinders Current System and paths of connectivity of pollutants, nutrients and marine biota.

These models will underpin research that aims to:

  • determine regional connectivity for scenario studies of hydrocarbon seepage and movement; and
  • understand ecosystem variability, from phytoplankton to the distribution of top predators.

Integrated Marine Observing System (IMOS) (external website)
IMOS operates a wide range of observing equipment throughout Australia's coastal and open oceans, making it accessible to the marine and climate science community, other stakeholders and users, and international collaborators. Their network provides the Great Australian Bight Research Program with valuable real-time data to better understand the physical and biological feature of the region. IMOS is one of the national research infrastructure capabilities supported under the Australian Government's National Collaborative Research Infrastructure Strategy (NCRIS).
