The research partnership over five years between Saildrone and our Oceans and Atmosphere team will see the deployment of state-of-the-art unmanned ocean surface vehicles, Saildrones, for the first time in Australian waters.Show descriptionHide description
UPDATE 23/3/2018: Our Saildrone fleet was unveiled in Hobart today, before setting off on a mission to capture valuable ocean data. Find out more here.
When you think of the role automation could play in your life you probably think of the latest fridges that plan your meals, having a chat with Google home, or maybe what life will be like working side by side with robots.
But have you ever thought about how automation is changing the way we collect ocean and climate data? Well wonder no more! The ocean technology industry is booming, with new devices, moorings and vessels coming online to plug gaps in how we collect these data across the world.
Many oceans to cross
Think about it – 71 percent of the Earth’s surface is covered by oceans. We know that the oceans control our climate through absorbing around 90 percent of heat energy from our skies and around 25 percent of the greenhouse gases emitted to the atmosphere. Oceans are also fundamental to our lives – they provide much of the food we eat plus 50 percent of the oxygen we breathe!
Getting around to study all of our oceans is quite a challenge. The Southern Ocean in particular covers about 20 percent of the area of all oceans and presents a unique challenge for scientists. This is one of the most important regions on earth for removing heat and carbon dioxide from the atmosphere and is undergoing ocean acidification, warming and circulation change that can impact ecosystems and influence rates of climate change. Rough seas and the small number of vessels which pass through this region (mostly in the summer months) limit our ability to detect change and understand the driving processes needed to predict the future state of the Southern Ocean and our climate.
For the coastal and regional seas around Australia, observations are also limited to a small number of sensor-equipped ships or moorings. There are few if any data that can be used to identify key changes in the marine environment which are similar to those occurring in the Southern Ocean. These data are needed to determine change or stress points and the consequences for our oceans and ecosystems.
Weâre working with San Francisco-based ocean technology start-up, Saildrone, to radically improve measurement and monitoring in Australian waters and the Southern Ocean.

We recently announced a partnership with San Francisco based ocean technology start-up Saildrone to introduce a fleet of revolutionary ocean vessels into Australian waters and the Southern Ocean.
The use of Unmanned Surface Vehicles (USVs) around Australia and in the Southern Ocean represents a huge technological leap in our capacity to monitor and observe the ocean, allowing scientists to develop a deeper understanding of how our ocean works.
Saildrones are solar and wind powered USV platforms that can go to sea for 12 months without returning to dock. Whilst at sea Saildrones can continuously collect information about temperature, salinity and carbon, sending data back to researchers via satellite.
The USV fleet can also be re-tasked quickly, providing a new way to measure ocean conditions associated with events like marine heat waves or toxic algal blooms. In the past it would have required extensive planning and expense for a ship and crew.
The team from Oceans and Atmosphere are collaborating with Saildrone to equip the vessels with some specialised equipment developed in house. The initial suite of sensors measures meteorological conditions, sea temperature, salinity, carbon dioxide, pH, oxygen, acoustics for fisheries research, and optical sensors are used to estimate plant biomass. Other sensors may be added to enhance capability as the partnership progresses.
