Remotely Sensed Spectral Variability Predicts Reef Fish Diversity
Bakker, A.C.B., Gleason, A.C.R., Dempsey, A.C., Bachman, S., Burdick, D., Tarano, A. M., Chirayath, V., & Purkis, S.J. (2024). Remotely sensed spectral variability predicts reef fish diversity. Ecological Indicators, 169, 112823. https://doi.org/10.1016/j.ecolind.2024.112823
This study combines UAV-based fluid lensing imagery and multispectral satellite data with fish biodiversity datasets the Living Oceans Foundation collected during the Global Reef Expedition to demonstrate how spectral variability can serve as a proxy for reef biodiversity, paving the way for non-invasive, large-scale biodiversity monitoring that complements traditional field-based surveys.

Serge, A., Maële, B., Stéphane, G. et al. Evaluation of the Allen Coral Atlas benthic habitat map product for New Caledonia using representative habitat observations from a multi-species fishery assessment. Coral Reefs (2024). https://doi.org/10.1007/s00338-024-02481-0.
Serge Andrefouet, a scientist who joined us on the Global Reef Expedition, assessed the accuracy of the Allen Coral Atlas's coral reef habitat maps in New Caledonia, and compared it to other reef maps, including the ground-truthed maps we created on the Global Reef Expedition, and found our maps to be more accurate.

Remotely sensed habitat diversity predicts species diversity on coral reefs
Anna C. Bakker, Arthur C.R. Gleason, Alexandra C. Dempsey, Helen E. Fox, Rebecca H. Green, Sam J. Purkis, "Remotely sensed habitat diversity predicts species diversity on coral reefs," Remote Sensing of Environment, Volume 302, 2024, 113990, ISSN 0034-4257, https://doi.org/10.1016/j.rse.2024.113990.
KSLOF's Chief Scientist, Dr. Sam Purkis, worked with his Ph.D. student, Dr. Anna Baker, to develop a new way to use satellites to analyze global reef biodiversity.

The 2022 Hunga-Tonga Mega-tsunami: Near-Field Simulation of a Once-in-a-Century Event
Sam J. Purkis, Steven N. Ward, Nathan M. Fitzpatrick, James B. Garvin, Dan Slayback, Shane J. Cronin, Monica Palaseanu-Lovejoy, and Alexandra Dempsey. "The 2022 Hunga-Tonga Mega-tsunami: Near-Field Simulation of a Once-in-a-Century Event." Science Advances.
KSLOF's Chief Scientist, Dr. Sam Purkis, used bathymetry data collected on the Foundation's Global Reef Expedition to model the size of the tsunami to hit Tonga in January of 2022. He and found that it was similar in size to the one caused by the eruption of Krakatoa in 1883.
