Big data

The amount of data collected depends on the research being undertaken and which sensors are turned on.

“The challenge is to estimate how much storage space we’ll need, and that will depend on whether big data generating systems are turned on, such as high definition video, radar, or the acoustic instruments,” Dr Kool said.

“And because we’re collecting so much information, we have to think big about how we manage it and distribute it on a much larger scale than anything we’ve done before.”

To do this Dr Kool has two portable, ruggedised data storage devices that can each store 80 terabytes of data.

Once captured, the data is formatted and organised to comply with the Australian Antarctic Division’s onshore data management system. At the end of each voyage the data from the hard drives are uploaded to a cloud for anyone to access.

“With the seabed mapping instruments, for example, we amalgamate all sorts of data, including the three dimensional position and orientation of the ship in space, and waveform information from the acoustic pings bouncing off the seabed,” Dr Kool said.

“Scientists can then download and process it to visualise the structure of the seabed and identify habitat characteristics – such as whether the seabed is rocky or silty.”

Open access

Free access to the data collected on Nuyina and elsewhere in Antarctica will contribute to improved weather and climate models, biodiversity models, navigation maps, and global efforts to map the world’s oceans by 2030.

“I’m a firm believer that better information leads to better decisions,” Dr Kool said.

“There’s a broad range of people who will end up using this data, including atmospheric scientists, meteorologists, biologists, climate experts, and members of the public.

“In time, my vision is that we can open up our entire Australian Antarctic data collection for big data research.”
