Steady state photosynthesis (photosynthetic induction time) from Porites astreoides colonies in St. John, US Virgin Islands from July to August of 2019

These datasets represent the time to steady state photosynthesis (photosynthetic induction time) of Porites astreoides colonies classified as inside or outside of octocoral canopies. These data were used to test for the potential effect of light regimes created by octocoral canopies on the photophysiology of autotrophic taxa within the understories of octocoral forests. Additionally, these datasets contain information on the octocoral community surrounding each P. astreoides colony. Data was collected between July and August of 2019 at ~ 7.0 ± 0.5-m depth at three sites (White Point, Tektite, Cabritte Horn) in Lameshur Bay St. John, U.S. Virgin Islands. 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).本数据集涵盖了归类于八珊瑚冠层（octocoral canopies）内部与外部的星状微孔珊瑚（Porites astreoides）群落的稳态光合作用所需时长（即光合诱导时间，photosynthetic induction time）。本数据集旨在验证八珊瑚冠层所构建的光照制度，对八珊瑚林下层生境中自养类群的光生理特性所产生的潜在影响。此外，本数据集还收录了每一株星状微孔珊瑚群落周边的八珊瑚群落相关信息。数据采集于2019年7月至8月，采集点位位于美属维尔京群岛圣约翰岛拉穆舒尔湾的3个站点（怀特角、特基特、布里特角），采集水深约为7.0±0.5米。 本数据集作为美国国家科学基金会（National Science Foundation, NSF）“美属维尔京群岛珊瑚礁时间序列：维尔京群岛国家公园珊瑚礁群落长期动态”项目的一部分完成采集，并已发表于Girard与Edmunds（2023）的研究成果中。
