Reflectance spectra of coral reef and seagrass communities from Heron Reef, southern Great Barrier Reef and Saipan Lagoon, Commonwealth of the Northern Marianas Islands

DOI

This project measured spectral reflectance for a variety of reef and seagrass functional groups found in Heron Reef, southern Great Barrier Reef and Saipan Lagoon, Commonwealth of the Northern Marianas Islands. Shark Bay, a reef flat in Heron Reef was sampled in Jan. 2016. Two sites were sampled in Saipan Lagoon, which included a reef flat, Pau Pau, sampled in June 2016, and a seagrass community, San Roque sampled in May 2016. An ASD (Analytical Spectral DevicesĀ®) HandHeld 2 spectrometer (325-1075 nm) in an underwater housing was used with a 2 m bare fibre optical cable to take reflectance spectra of functional-groups and substrates in-situ. A flashlight was mounted to the tip of the optical cable, in cases where dim lighting reduced signal output. The tip of the fibre optic cable was held at a uniform distance from the subject, ~7 cm to collect spectra. Reflectance (R) was determined from the ratio of upwelling (Lu) to downwelling (Ld) radiance (R = Lu/Ld). Targets were measured in less than 2 m depth, and included sand substrate, coral identified to the genus level, macroalgae, calcareous algae, turf, and seagrass identified to species level.
