Long-term observations reveal increasing Trichodesmium in Australian waters
Long-term observations collected through the IMOS National Reference Stations (NRS) Facility are helping researchers uncover changes in one of the ocean’s most important nitrogen-fixing organisms. Trichodesmium is a filamentous cyanobacterium that converts nitrogen from the atmosphere into a form that can be used by other organisms. This makes it an important part of nutrient cycling,…

Building a national picture of Australia’s coastal waves
Waves are a fundamental component of the ocean–atmosphere system, transporting energy and momentum across the ocean and playing an important role in understanding climate variability. Accurate observations of coastal waves are critical for understanding and predicting coastal processes. Wave measurements are used to develop, validate and improve numerical models, support hazard forecasting and data assimilation,…

20 years of Argo: a significant contribution to global ocean observing through IMOS
For more than two decades, autonomous Argo floats have been transforming our ability to observe the ocean beneath its surface. Drifting through the upper ocean, Argo floats repeatedly profile from the surface to around 2,000 metres, measuring temperature, salinity and pressure before returning their observations by satellite. Biogeochemical Argo floats measure properties such as oxygen,…

20 years of animal-borne ocean observing by the IMOS Animal Tagging Facility
For two decades, the IMOS Animal Tagging Facility has equipped seals and sea turtles with ocean sensors to collect temperature, salinity and depth data from the Southern Ocean to the tropics. With more than 1,100 tagged animals generating over 440,000 ocean profiles filling major gaps in remote ocean observation. These animal-borne sensors improve our understanding…

Tracking sea-level rise: IMOS delivers critical satellite validation
Celebrating 20 years of sustained marine observing The sea level climate data record derived from satellite altimetry underpins how we understand the ocean and its response to a changing climate. By capturing measurements of waves, tides, circulation and long-term sea level trends, this record provides critical evidence for science, policy and decision-making. Ensuring its accuracy…

IMOS marks 20 years of ocean observing at the 2026 Annual Meeting
The IMOS community recently came together in nipaluna, Hobart to celebrate two decades of nationally coordinated ocean observing at the 20th Anniversary Annual Meeting. The milestone event highlighted the critical role of IMOS, enabled by National Collaborative Research Infrastructure Strategy, in delivering long-term observations that underpin marine science, climate research, and decision-making. The three-day program…
