The oceans around us affect almost all aspects of our lives - from our weather and climate, through to our food and well-being. Australia marine estate is the third largest in the world, and is highly diverse with many unique components. From our coastline to the abyssal ocean, from the tropics to Antarctica, scientific research is central to understanding how the oceans work and managing human activities that depend on it or affect it.

The world's oceans are connected and collectively influence global climate, marine biodiversity, transport, and fisheries. So whilst Australian marine research often takes place within the Australian marine estate it does include important regional (e.g. fisheries) and international (e.g. oceanography, blue carbon) science collaborations. In Australia, collaborative research is underpinned by important infrastructure like the Marine National Facility and the Integrated Marine Observing System. Our scientists are at the forefront of marine research, find out why.
The Oceans book, produced by CSIRO Publishing, provides a brief, accessible description of some of the key features of our marine estate, overviews of some areas where primary marine activities are supported by research, and some predictions of what marine research might look like in the near future.Read the Oceans book
Our oceans are accessed and used by a diverse range of people, communities and industries, who in many cases have competing interests. From fisheries to search and rescue, from energy production to ocean pollution, from coastal development to ocean based transport, this book section explores how Australian marine science is being applied to understanding the mixture of uses, the impacts of human use, and how ocean use can occur sustainably.Read more about sustainable fisheries
Technological innovation in the marine sector is accelerating at an unprecedented rate. Observation and analysis of oceans is predicted to become increasingly automated and the proliferation of robots will change what research can achieve and how long it will take. New ocean variables are being measured from space, and citizens are becoming more engaged. This book section looks at the future trends in ocean science and future challenges we will need to overcome.Read more about marine technologies
Australia lies in the ocean dominated Southern Hemisphere and is surrounded by oceans that play key roles in determining the weather and climate we experience. Oceans store around 93% of the heat that is accumulating in the Earth system, whilst warming oceans and loss of mass from glaciers and ice sheets is causing sea levels to rise. Ocean acidification is a consequence of rising atmospheric carbon dioxide, and coastal regions are subject to danger from cyclones, storm surge and inundation. Read more about oceans and climate.

[Music plays and an image of a spinning world globe appears and then images appear inset across the world globe of Australia’s marine territory and a small spinning world globe and text headings appear: Marine Estate, Australian Marine Territory]
Narrator: Australia has the third largest marine estate in the world extending from the coast to the abyssal ocean, from the tropics to Antarctica.
[Inset image changes to show a large sea turtle swimming and then the inset image changes to show a colourful fish swimming around coral]
Our vast marine estate includes an immense diversity of plants and animals, energy and mineral resources.
[Inset image changes to show fish swimming in the ocean and then inset image changes to show an aerial view of Australia’s marine estate]
Oceanographic research is central to both understanding our marine estate and managing our activities that depend on it or affect it.
[Image changes to show the spinning world globe and then an inset ocean map and a world globe appear across the spinning world globe and text headings appear: MH370, ATC Transmission Lost 01:22 MYT]
International incidents such as the MH370 airline tragedy highlight the need for advanced predictive forecasting and hindcasting to quickly support search strategies.
[Image changes to show the spinning world globe again and then new inset images appear across the spinning world globe of two ships, a coastline map and a spinning world globe and text headings appear: Defence Force, Naval Combat and Tactical Operations]
Marine research such as ocean forecasting assists our Defence Force naval combat and tactical operations.
[Image changes to show the spinning world globe again and then new inset images appear of people cleaning up on the beach and a spinning world globe and text headings appear: Environmental Disaster, Marine Industry]
Our coastline is huge, brimming with biodiversity which would be at significant risk during an environmental disaster such as an oil spill. To respond, Australia has strategies to minimise risk, prepare for and respond to incidents in a swift and informed manner.
[Inset image changes to show a predictive model map and text headings appear: Environmental Disaster, Natural Disaster response]
Predictive models and oceanographic monitoring assists us to predict storm surge impact of a cyclone or where a tsunami might hit.
[Image changes to show the spinning world globe again and then inset image appears across the globe of a piece of marine science equipment being deployed and text headings appears: Monitoring, Data Collection and Interpretation]
This helps us to determine which early warning and evacuation procedures to use.
[Inset images move through of a male working on a computer, the computer screen and the small spinning world globe]
We use satellites, ocean buoys and computer models to monitor the ocean in near real time and predict what it will do in the future.
[Image changes to show the spinning world globe and then inset images appear in front of the globe of surf rolling in on the shore and a small spinning world globe and text headings appears: An Ocean Nation, Science and Solutions for Australia]
Our ongoing commitment to oceanographic research and technology development will ensure positive outcomes for our vast and precious marine estate now and into the future.
