These data represent simultaneous measurements taken by a HOBO light intensity logger (model UA-0002-64) measuring in lux and a cosine-corrected PAR sensor (LI-192, Li-Cor Biosciences) fitted by the manufacturer into a logger (miniPAR, Precision Measurement Engineering) measuring PAR in µmol photon m-2 s-1. This was done at the Tektite site at 9 m depth in Lameshur Bay, St. John, U.S. Virgin Islands during January of 2021. This was done to cross-calibrate illuminance data (lux) from the HOBO log...

Tektite site in Lameshur Bay, St. John, U.S. Virgin Islands at 9-m depth
Research conducted from the University of the Virgin Islands Marine Station in Lameshur Bay in Jan 2019.
Methods & Sampling:
The HOBO and PAR logger were synchronized, deployed next to one another at 9-m depth with their light sensors at the same depth and perpendicular to the surface. Loggers were deployed at the Tektite site, and set to take a light measurement once every minute. Loggers started sampling at 14:05:00 (Local Time, Atlantic Standard Time, GMT -4) on January 25th 2021 and stopped sampling at 16:45:00 on January 27th 2021. Sampling days were characterized as clear, and sunny with few passing clouds and a calm sea state.
