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

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).

本数据集包含两组同步观测数据：分别由以勒克斯（lux）为单位的HOBO光照强度记录仪（型号UA-0002-64），以及由生产商预装于miniPAR记录仪（Precision Measurement Engineering）中的余弦校正光合有效辐射（Photosynthetically Active Radiation，简称PAR）传感器（LI-192，Li-Cor Biosciences）采集所得，后者以微摩尔光子每平方米每秒（µmol photon m⁻² s⁻¹）为单位测量光合有效辐射。本次数据采集于2021年1月，观测站位为美属维尔京群岛圣约翰岛拉梅舒尔湾（Lameshur Bay）的泰克蒂特（Tektite）海域9米水深处。本次观测参照Long等人2012年的研究方法，旨在将HOBO记录仪获取的照度数据（勒克斯）与光合有效辐射数据进行交叉校正，以辅助照度数据的生态学解译。

本数据集隶属于美国国家科学基金会（National Science Foundation，简称NSF）资助的「美属维尔京群岛珊瑚礁时间序列」项目——美属维尔京群岛国家公园长期珊瑚礁群落动态研究，相关研究成果已发表于Girard与Edmunds（2023）的学术论文中。
