If you have ever wanted to print your own coral reef, then today is your lucky day. A team of marine scientists is capturing coral reef segments in all of their 3 dimensional glory using photogrammetry equipment. They are then turning the data captured through these scans into 3D models. It has all been surprisingly simple, requiring only an underwater digital camera and Autodesk ReCap reality capture software.
The researchers are part of the non-profit organization The Hydrous that focuses on pressing current coral reef science topics and research, and specializes in the use of innovative and intuitive visualizations to help translate scientific data. Marine scientist and founder of The Hydrous, Sly Lee described the benefits of using this technique to capture and study coral reef data:
The models can also be used as part of coral reef education initiatives, allowing students and community members to interact with coral, even if they never go anywhere near an ocean. Creating this type of connection between individual and environment is an important part of the stewardship necessary to generate the initiative to protect these corals. Dr. Ruth Gates of the Hawaii Institute of Marine Biology understands how helpful these models can be to efforts to protect coral reefs:
If you want to print out your own corals, two models have been made available for download. You can see more models in orbit mode by visit The Hydrous website coral experience page. Let us know if you have decided to print out one of these beautiful pieces, and feel free to post a picture or two in the 3D printed coral forum thread on 3DPB.com. Feel free to play around with the model below.
Abstract:Underwater photogrammetry has been increasingly used in coral-reef research in recent years. Habitat metrics extracted from resulting three-dimensional (3D) reconstructions can be used to examine associations between the structural complexity of the reef habitats and the distribution of reef organisms. We created simulated 3D models of bare surface structures and 3D reconstructions of coral morphologies to investigate the behavior of various habitat metrics that were extracted from both Digital Elevation Models (DEMs) and 3D mesh models. Analyzing the resulting values provided us with important insights into how these metrics would compare with one another in the characterization of coral-reef habitats. Surface complexity (i.e., reef rugosity), fractal dimension extracted from DEMs and vector dispersion obtained from 3D mesh models exhibited consistent patterns in the ranking of structural complexity among the simulated bare surfaces and coral morphologies. The vector ruggedness measure obtained from DEMs at three different resolutions of 1, 2, and 4 cm effectively captured differences in the structural complexity among different coral morphologies. Profile curvature and planform curvature, on the other hand, were better suited to capture the structural complexity derived from surface topography such as walls and overhanging ledges. Our results indicate that habitat metrics extracted from DEMs are generally suitable when characterizing a relatively large plot of a coral reef captured from an overhead planar angle, while the 3D metric of vector dispersion is suitable when characterizing a coral colony or a relatively small plot methodically captured from various angles.Keywords: underwater photogrammetry; Digital Elevation Model; 3D mesh model; coral reef; structural complexity; habitat metric
Researchers in Israel have developed a method of 3D printing corals to help regrow bleached reefs. We spoke to Natalie Levy, a PhD candidate at the Mina and Everard Goodman Faculty of Life Sciences at Bar-Ilan University to find out more.
Our partners from the University of Haifa have taken thousands of underwater images that they have stitched together in imaging software to create a model. This model is a realistic computer model of the exact reef. It is extremely accurate and has fine-scale details. You can move it around, you can zoom in on it, everything like that. And also you can tag and label different coral species.
It's been known for a while that the ceramic terracotta is a great material for coral organisms and the methods we're using have been working great. We found that we were able to see all the main reef building organisms, a lot of coral, soft corals, other organisms that were the same as the ones seen in the reef that we put them in.
That's the idea. We wanted to implement an algorithm and a model that could be employed for any coral reef that needs this kind of technology. So you could go and take 3D scans or models of reefs in Colombia or Panama or Brazil or Hawaii.
People also are working on the 3D modelling technology, the 3D imaging. It's something that institutions are currently implementing. You can download the models from the Internet for free. For example, I could take the models and build you a reef. Anyone can do the exact same process. So if people need it for helping their coral reefs they can use the technology wherever they are.
Well, the dream is, if we can get some big funding, we would like to implement this project in several coral reefs all over the world. Our philosophy is that we want to help all coral reefs that are degrading. The idea is to have a massive coral reef restoration project using our structures for wherever people need to add to reefs, to allow corals to settle and to grow. People anywhere in the world could use our technology. We're really looking for people that are able to help us, to work with us, to help to contribute to the dream of protecting the reef.
The successful recruitment of reef-building corals is a crucial process for ensuring the longevity of coral reef ecosystems. Once recruited, post-settlement facets of survivability such as predation, habitat suitability, and water quality affect the viability and growth rate of the coral spat . Thus, it is important to understand how the survivorship of coral spat may be affected if they settle on 3D printed materials intended for use as settlement sites on natural reefs. Under controlled conditions, P. astreoides chose to settle significantly more in aquaria containing 3D printed tiles compared to control aquaria with no tiles. This result suggests the 3D printed tiles were successfully designed to provide a textured surface that recruiting corals have shown to prefer . While it was not in the scope of the current study to broadly compare settlement rates on 3D printed tiles to more traditional settlement surfaces, this assessment would be valuable for exploring potential alternatives to conventional methodologies.
Percent mortality of corals settled on treatment tiles was comparable to rates observed for P. astreoides in other studies. On conditioned limestone tiles, survival of P. astreoides spat settled under controlled conditions was 10% after 24 hours in situ . After 12 weeks in the current study, survival ranged from 21% (nGen) to 48% (SS). While the rate of survival for P. astreoides settled on 3D printed tiles under controlled conditions is higher than the rates found in other studies, it is likely that mortality would increase if tracked in situ. Newly settled corals are extremely vulnerable to predation and abiotic stressors, resulting in low rates of juvenile survivorship . However, it can be inferred from the results of this study that 3D printed materials did not have increased immediate or latent post-settlement effects on P. astreoides survival under controlled conditions. Future studies should track growth and survivorship of juvenile corals on 3D printed substrate in a reef setting.
Reef fish predation , recruitment , and habitat choice  studies traditionally require construction of isolated patch reefs, where live coral is detached from the contiguous reef. Live coral may also be experimentally bleached to investigate interspecific effects of habitat degradation ; 3D printed corals could alleviate stress on the reef that would conventionally be incurred in similar experiments. For instance, 3D printed Caribbean staghorn corals (Acropora cervicornis), used to assess habitat preferences of reef fishes, were shown to attract similar numbers of fish as natural A. cervicornis when created with sufficient structural complexity . Demonstrably, 3D printed models mimicking natural habitats can act as suitable proxies in controlled and dynamic environments and could be used in place of live coral when appropriate. 2b1af7f3a8
