About the research project
The southern coast of Australia has been identified as a climate change hotspot, with the increased poleward penetration of the East Australian Current accelerating the warming rate. An implication of this change is the range-extension of several species, including the long-spined sea urchin's arrival to the Tasmanian East coast. This sea urchin can overgraze kelp forests, turning healthy habitats into barren grounds. Significant changes have been observed in the structure and functioning of the Tasmanian reef system because of its invasion, which has also impacted the valuable rock lobster and abalone fisheries.
Underwater imagery has proven to be a powerful tool for monitoring benthic communities and habitats. Hence, a camera system was developed for this purpose, the so-called POTBot (Picture Of The Bottom), which may be mounted on rock lobsters pots. POTBot units are equipped with a camera system, including underwater sensors, to record videos and georeferenced environmental data. The units deployed by lobster fishers provide an opportunity for state-wide information collection for monitoring spatial and temporal changes of conspicuous marine species and habitats.
Underwater images have been typically human analysed, which is time-consuming, costly, and unsuitable for ongoing programs. Hence, Artificial Intelligence arises as a solution. For instance, Deep Learning (DL) approaches have been successful in automatic underwater object identification. This type of algorithm includes different architectures of Deep Neural Networks (DNN), already used for aquatic object identification. Still, challenges remain unresolved in image recognition of aquatic environments. Such matters include water turbidity, insufficient light, complex background, morphology of organisms, etc. Thus, the challenge is to address the complexity of aquatic environments by using optimal DNN techniques to improve the efficiency of marine habitat recognition. This project aims to employ currently available and develop new Deep Learning algorithms to recognise conspicuous species and habitats and improve ongoing monitoring.
