Ecologists are using the latest dental scanning technology to study young corals

Dr Kate Quigley, inspired by a visit to the dentist, introduces a new method of monitoring coral size and growth that cuts survey time by 99%. The methodology and findings are published in the journal British Ecological Society, Methods in Ecology and Evolution.

Dr. Kate Quigley, a senior researcher at the Minderoo Foundation, who has conducted research at the Australian Institute of Marine Science and James Cook University, has developed a new non-destructive method for scanning corals quickly and safely – limiting the previously laborious. and lengthy surveying techniques.

Inspired by a visit to the dentist, Dr. Quigley noted the similarities between coral and our teeth—both are calcium-based and require measuring tools that can withstand wet surfaces. “One day I was at the dentist and they started this new scanning machine. I knew immediately that this was something that could be applied to scanning very small corals, because corals and teeth actually have many similar properties. The rest is history! “

Coral reefs are among the most productive ecosystems on Earth, providing essential nutritional and protective services to people around the world. These important ecosystems have suffered severe decline in recent decades – prompting a flurry of research into their basic biology and restoration. Understanding the critical life stage of juvenile corals allows scientists to predict ecosystem changes, impacts of disturbance and their potential for recovery.

Reconstruction of 3D models of corals reveals insights into their health and response to pressures such as rising temperatures or acidification. There are several methods for building and assessing these 3D models, but their effectiveness is reduced when constructing measurements at small scales.

Dr Quigley said: “It is currently difficult to accurately measure very small objects in 3D, especially if you are interested in measuring small living animals such as corals without harming them.

“During my PhD, one scan would take half a day to produce and I was interested in scanning hundreds of corals at once.

“For the first time, this new method will allow scientists to measure thousands of tiny corals quickly, accurately and without any negative health effects on the corals. This has the potential to expand large-scale monitoring of ocean health and increase the scale of corals.” reef restoration.”

To assess the effectiveness of these dental scanners, namely the ITero Element 5D Flex, Dr. Quigley measured juvenile corals in the Australian Institute of Marine Science’s National Sea Simulator. Corals from the Great Barrier Reef were temporarily removed from their indoor aquaria and their surface area and volume were recorded before being returned to the tanks.

It took an average of less than three minutes to scan and build a model of each individual coral, compared to more than 4 hours with previous methods – a 99% reduction in the time needed to make such measurements. Dr. Quigley noted equally fast and accurate performance when measuring and comparing models of dead skeletons and live coral tissue. There is no need to sacrifice live animals for measurement.

While this is a huge step forward in reducing the time needed to observe and study small marine animals, the 3D scans still need to be processed manually, which slows down analysis. Dr Quigley hopes the next avenue for this research is to try to create an automated analysis pipeline from scan to measurement, potentially using AI.

Currently, this technology can only be used for off-water measurements. The hardware is not waterproof because the scanner relies on confocal laser technology.

“Potentially, the scanner could be completely waterproof. However, it’s not clear how well the laser technology would work completely submerged. We’ve taken this technology on a ship before and brought wild and lab-grown corals to measure, so getting there!”
