UNDER REVIEW: MCR LTER: Coral Reef: Benthic Photosynthetically Active Radiation (PAR), ongoing since 2009

These data in this data package are currently under review for further quality assurance and should
not be utilized at this time. These data contain a time-series from
sequential deployments of an ALW-CMP PAR sensor recording quanta of photosynthetically active
radiation (PAR) underwater between wavelengths 400 nm to 700 nm every two seconds. The
sensor window is wiped free of algae periodically to prevent fouling. Deployments are
three to six months in length. The sensor was mounted at 17 m depth on the fore reef, and at
2 m depth on the Backreef. PAR irradiance is measured as quanta in micromoles of photons per square meter per second. This material is based upon work supported by the U.S. National Science Foundation under
Grant No. OCE 16-37396 (and earlier awards) as well as a generous gift from the Gordon and
Betty Moore Foundation. Research was completed under permits issued by the French Polynesian
Government (Délégation à la Recherche) and the Haut-commissariat de la République en
Polynésie Francaise (DTRT) (Protocole d'Accueil 2005-2018). This work represents a
contribution of the Moorea Coral Reef (MCR) LTER Site.
