Utilizing 3D reconstruction techniques to assess the impacts of disturbance on coral reef habitats


The structural complexity of coral reefs plays a major role in the biodiversity and productivity of reef ecosystems. Conventional surveys use 2-dimensional properties that are incapable of accurately measuring habitat complexity. A 3-dimensional (3D) approach can better quantify structural characteristics that play an important role in the ecology of coral reef communities. Structure-from-Motion (SfM) is a cost-effective and efficient method for high-resolution 3D habitat reconstruction. Our research utilizes SfM software tools to create 3D models of coral reefs throughout the Hawaiian Archipelago. The resulting data enables us to determine specific coral species that are key drivers of 3D habitat complexity. The technique is also used to assess the impacts of natural disturbances on the volume and structure of coral communities. Ultimately, 3D reconstructions of reef structure and complexity can improve the capacity to monitor changes in the health and function of coral reef ecosystems.


John Burns, from the Hawai’i Institute of Marine Biology at UH Mānoa, will discuss efforts to restore coral health around Hawaiʻi. This lecture is sponsored by the school of Tropical Conservation Biology and Environmental Science.

Special Restrictions: All are welcome!
