Pulse Amplitude Modulation (PAM) fluorometer measurements from Porites astreoides colonies in St. John, US Virgin Islands from July to August of 2019

These data represent the raw Diving Pulse Amplitude Modulation (PAM) fluorometer measurements from 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).
