Australia and UK collaborate on high-view water quality monitoring from orbit

AUSTRALIA’S AQUAWATCH system – a mission to develop a ‘weather service’ for water quality – will be established in the UK, following bilateral support and co-funding from the two countries’ space agencies.

CSIRO, Australia’s national science agency, launched AquaWatch Australia in 2023 with foundational partner SmartSat Cooperative Research Centre (CRC) and a network of collaborators. The collaborators developed a national system for monitoring water quality, including early warning forecasts.

Since launching, AquaWatch has established multiple test sites with the ability to monitor bays, coastal wetlands, rivers, dams, lakes, aquaculture farming and coral reefs, including the Southern Great Barrier Reef. 

The creation of AquaWatch UK is the first time the initiative will be rolled out by another country on a national scale, expanding on a test site at Plymouth Sound.

AquaWatch was announced as a supported project under the UK Space Agency’s International Bilateral Fund, with co-funding from the Australian Space Agency, as part of the longstanding UK-Australia Space Bridge initiative. 

Under the UK-Australia Space Bridge, partners will receive funding to advance the AquaWatch system in Australia and establish AquaWatch in the UK, leveraging expertise and technology across both countries.

 

Sensors are space and water based

AquaWatch Australia mission lead, Alex Held, said AquaWatch integrated data from both a network of water-based sensors and satellite sensors.

“It’s a system we’re developing for Australia, but that can be adapted for other countries in need of national near-real time updates and forecasts,” Dr Held said.

“The importance of high-quality satellite data for AquaWatch means that global collaborations such as this help to enhance the system for everyone.”

Head of the Australian Space Agency, Enrico Palermo said this funding buildt on the collaboration fostered through the UK-Australia Space Bridge.

“By working with our international partners like the UK, we can continue to grow the Australian space sector while delivering outcomes that benefit communities in both of our nations,” Mr Palermo said.

“Projects like AquaWatch reiterate how space technology, like Earth observation, can help address the biggest global challenges we are facing, as well as the power of working together to solve a common problem.”

SmartSat Cooperative Research Centre CEO, Professor Andy Koronios, said SmartSat established strong ties with the UK space industry with the first UK Space Bridge initiative, funding five outstanding joint research initiatives in 2021.

“The AquaWatch UK project further underscores SmartSat’s commitment to delivering next-generation technologies and innovative projects that will accelerate the space sector in both Australia and the UK,” Prof Koronios said.

Space Bridge partner takes the UK lead

Surrey Satellite Technology Ltd (SSTL) has been named as the leading partner for delivering AquaWatch in the UK.

Head of SSTL Australia, Clive Oates said the collaborative AquaWatch AUK project would build on SSTL’s strong commitment to the UK-Australia Space Bridge to “help unleash the potential of disruptive space technologies”  and develop a “world class integrated water quality monitoring and forecasting system” for implementation across Australia, UK and beyond.  

“Working with CSIRO and SmartSat CRC on a comprehensive spacecraft platform study will also help accelerate Australia’s capability in the design, manufacture and test of Earth observation capabilities across both academia and industry,” Mr Oates said.

The collaboration will expand on test sites already established across Australia and with Plymouth Marine Laboratory (PML) in the UK, where AquaWatch is being tested to monitor water quality from the Tamar Bridge in Plymouth, Southwest England.

Earth observation scientist at PML, Elizbeth C Atwood said the test site in Plymouth was monitoring run-off from the Tamar and Plym rivers to the estuary and coast, which can transport sewage, agricultural run-off, heavy metals from mine waste and range of other human-caused pollutants.

“Given these challenges, Plymouth Sound, which hosts the UK's first National Marine Park and a Marine Social and Natural Capital Laboratory initiative, is an ideal testbed for CSIRO’s AquaWatch system through the EO4Agriclimate Vis4Sea project,” Dr Atwood said.

Merit scientist at PML and principal investigator of Vis4Sea, Gavin Tilstone said as the planet “heats up from global warming, we see increased flooding events”.

“Using the AquaWatch infrastructure for Plymouth Sound, Vis4Sea is building a system to monitor the impacts of flooding on water quality, mud flats and sea grass beds, which play an important role in capturing CO2 from the atmosphere,” Dr Tilstone said.

 

Living Coasts program dovetails AquaWatch

Another EO4Agriclimate project, Living Coasts, is advancing the use of satellite observations to map land and water environments and their dynamics.

Living Coasts researcher, Richard Lucas of Aberystwyth University said this allowed AquaWatch users to gain a more complete picture and understanding of changes driving water quality.

“Working with Australian and UK partners, we are implementing our approach through data cubes of satellite data for both countries, but also in other regions including Southeast Asia, with this contributing to efforts focused on improving environments for people and nature,” Professor Lucas said.

The AquaWatch AUK project highlights the important role space technology has to play for sustainable development and environmental stewardship in both countries.

In addition to CSIRO, SmartSat CRC and SSTL, AquaWatch AUK is supported by Assimila, RAL Space, Pixalytics and the Centre for Environment, Fisheries and Aquaculture Science (CEFAS).
