Simultaneous light intensity measurements from a HOBO light intensity logger and a cosine-corrected PAR sensor in Lameshur Bay, St. John, U.S. Virgin Islands in January of 2021

Abstract

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 logger to PAR (µmol photon m-2 s-1) (after Long et al. 2012) for assistance in the ecological interpretation of illuminance data.

These data were collected as part of an NSF Coral Reef Time Series, Virgin Islands: Long-term coral reef community dynamics in the Virgin Islands National Park and were published in Girard and Edmunds (2023).
