Long-term IMOS observations reveal changing Southern Ocean phytoplankton communities
New research using 10 years of long-term observations from the IMOS Southern Ocean Plankton sub-Facility has revealed an increase in phytoplankton abundance. Phytoplankton are microscopic marine organisms that form the foundation of Southern Ocean food webs. They are an important food source for Antarctic krill, which in turn support fish, seabirds, seals and whales. Changes…

Tasmania’s coastal water monitoring strengthened with new IMOS Moorings
Two new IMOS Estuarine and Coastal Moorings have been deployed in the south-east of Tasmania, to cover critical spatial and observational gaps in long-term, high frequency water quality monitoring in this area. The Tasmanian moorings form part of a coordinated network of water quality observations across Australia’s coastal and estuarine environments. Built and deployed by…

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,…

South Australian coastal mooring data now available in the IMOS Australian Ocean Data Network
Near real-time observations from South Australia’s Harmful Algal Bloom coastal monitoring network are now available through the Australian Ocean Data Network, expanding the data available through the IMOS Estuarine and Coastal Moorings Facility. Federal and state government funding has enabled the South Australian Research and Development Institute (SARDI) to install the current South Australian Harmful…

New IMOS moorings strengthen coastal water quality monitoring in Victoria
Two new IMOS Estuarine and Coastal Moorings will be deployed in Western Port Bay and Corio Bay, to establish a coordinated network of water quality observations across Australia’s coastal and estuarine environments. Deployed by Deakin University, in collaboration with the Environment Protection Authority Victoria, Port of Hastings Corporation and Melbourne Water, the new moorings will…

Mapping vessel traffic across Australia’s oceans
Australia’s waters host some of the busiest shipping routes in the southern hemisphere, with thousands of vessels moving through coastal and offshore regions each year. The Australian Maritime Safety Authority (AMSA) captures this activity through its national Automatic Identification System (AIS) network, generating a vast dataset of vessel movements, now exceeding 200 million records. Despite…
