Integrated Marine Observing System - IMOS Australia's Integrated Marine Observing System (IMOS) is a national collaborative infrastructure

IMOS is a collaboration of Australia's leading marine research organisations, using a network of advanced technologies to make ocean data freely available.

Two new IMOS moorings are strengthening coastal water quality monitoring in Tasmania, helping researchers better understand the conditions shaping our coastal environments.

The moorings are providing ongoing observations of coastal waters, supporting research into environmental change and helping build a clearer picture of how these important ecosystems are changing over time.

These moorings are part of the Coastal Research Infrastructure (CoastRI) initiative. CoastRI, is a national initiative under Australia’s National Collaborative Research Infrastructure Strategy (NCRIS) and is coordinated across 13 NCRIS capabilities.

Long-term ocean observations are revealing important changes in Trichodesmium, a nitrogen-fixing organism that plays a vital role in marine ecosystems.

Data collected through the IMOS National Reference Stations Facility is helping researchers uncover increasing Trichodesmium abundance in Australian waters, providing new insights into how this important organism is changing over time.

Discover what two decades of observations are revealing about this influential part of the marine environment.

An IMOS ocean glider is extending Australia’s observing capability into one of South Australia’s least-monitored marine regions. A glider was recently deployed off Fowlers Bay in the eastern Great Australian Bight, where it is sampling the broad, ~200 km continental shelf to better understand shelf processes and the behaviour of the South Australian Current.

One of the major findings of the IMOS ocean glider program is dense shelf water transport on Australian continental shelves; where cooler, more saline water at the coast is transported offshore along the bed. The deployment is targeting this flow pattern linked to the Great Australian Bight’s unique “mega-estuary” system.

This massive coastal gulf has much greater evaporation than freshwater input, creating unusually salty, dense water that can flow out across the shelf in winter. The cascading outflow is expected to be strongest between August and November, and early data suggest the glider may have captured exactly what researchers were hoping to observe.

With more than 30,000 kilometres of coastline, Australia needs reliable observations of how waves behave along our coast.

Historically, wave observations have been collected through regional programs, creating gaps in coverage and differences in how data are collected, processed and shared.

Over the past decade, IMOS has been working to build a more nationally coordinated approach. The IMOS Coastal Wave Buoys Facility provides observations essential for understanding wave-driven processes and change in coastal zones, including wave and water temperature conditions.

The Facility is also one of the initial investments contributing to CoastRI, the new NCRIS capability designed to strengthen Australia’s ability to observe, understand and respond to change across the coastal environment.

Integrating coastal wave observations with CoastRI will improve observing efficiency and expand data applications, including model validation and data assimilation, while enabling co-located observations of waves, water levels, currents, erosion and other environmental variables.

Australia’s Sustainable Ocean Plan has been released, marking the first time the nation has come together as a country to agree on a shared national vision for our ocean. The plan will help us work together for a healthy ocean that supports a strong and fair ocean economy.

The plan also recognises IMOS as part of Australia’s strong foundations in marine science, ocean monitoring and sharing ocean data.

By working together across industries, communities, groups and governments, we can grow our ocean economy and protect the health of our ocean and the coastal places we love and rely on.

The Exposure Draft of the 2026 National Research Infrastructure (NRI) Roadmap is now available for comment.

The Roadmap is an important document for the future of the National Collaborative Research Infrastructure Strategy (NCRIS) and its capabilities, including IMOS. It outlines Australia’s research infrastructure needs over the next 5–10 years, helping to support discovery, strengthen collaboration between researchers and industry, and drive innovation.

We encourage everyone with an interest in Australia’s research future, including researchers, research organisations and industry professionals, to review the draft and provide feedback.
