Low-Cost Camera TechnologyPart of AusOcean's mission is to develop and share low-cost ocean technology to increase the accessibility of ocean science and data. A top priority is continuous underwater video from both a scientific and public engagement point of view.
Our low-cost underwater cameras are designed to remain at sea for months at a time, live-streaming footage to the cloud. Our newest design uses a mineral oil filled PVC housing with a pressure compensating membrane made from a 3 layer nitrile glove thumb. The pressure compensating membrane is stretched over a pressure plug with a drilled out hole and inserted into a socket on the rear cap. The membrane allows water to push on the internal mineral oil medium equalising the internal pressure. Threaded connections have been implemented in 4 places, namely, the viewing window, rear cap, cable plug and pressure membrane plug. This allows the housing to be easily opened for repair/maintenance and ensures component reusability. Furthermore, this streamlines the construction process and reduces the amount of time required for assembly.
We are working towards the development of software which can automatically identify species. This means creating software which performs accurate count, size, and species ID of fish and other marine species in real-time. Such applications will revolutionise the way marine science is conducted and drastically expand our data acquisition capabilities.

AusOcean is a not-for-profit ocean research organisation that supports open source practices. Open source approaches to tackling environmental issues means embracing collaborative tools and workflows which enables processes and progress to be fully transparent. A critical aspect of working open is sharing data not only with your immediate team but with others across the world who can learn, adapt and contribute to collective research. By contributing to, and supporting open practices within the scientific community, we can accelerate research and encourage transparency.
