Photosystem II (PSII) photochemical efficiency (Yield PSII) recorded at noon (ΔF/Fm') and at dusk (Fv/Fm) on corals from the species Orbicella faveolata, transplanted from Varadero and Rosario reefs, Colombia, May 2017 (NCEI Accession 0291595)
This dataset contains data collected from 2017-05-20 to 2017-05-27. These data include depth. The instruments used to collect these data include Fluorometer. These data were collected by Mónica Medina and Roberto Iglesias-Prieto of Pennsylvania State University as part of the "RAPID: Coral robustness: lessons from an "improbable" reef (Varadero Reef)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-03-04.

PSII coral transplants
Dataset Description:
These are primary data of the PSII photochemical efficiency (Yield PSII) recorded at noon (ΔF/Fm') and at dusk (Fv/Fm) in a reciprocal transplant experiment and on random colonies. The data reported here were obtained from coral fragments used in a transplant experiment.
The Varadero Reef is located south-west of the Cartagena Bay close to the southern strait that connects the Bay to the Caribbean Sea in Colombia (10°18’23.3”N, 75°35’08.0”W). The Bay is a receiving estuary from the Magdalena River through the Canal del Dique, a man-made channel whose construction and operation dates back almost a century. Three study sites with contrasting light regimes were considered in order to evaluate the role of the light-environment perturbation associated with the Dique channel freshwater plume on the photosynthetic performance of corals from Varadero: 1) Varadero reef at 3.5m depth close to the Dique channel mouth (10°18’23.3”N, 75°35’08.0”W), 2) Rosario reef at 12m depth as clear-control site 21 km southwest from Varadero (10°11'12.1"N, 75°44'43.0"W), and 3) Cartagena Bay at 3m depth, the closest site to the Dique channel mouth and most turbid among the three sites (10°18'5.80"N, 75°34'37.10"W).
These data were used in the manuscript “Degradation of the underwater light environment: physiological and ecological consequences for reef corals” submitted to the Journal Nature Communications Biology. [under review. 2019-12-28]

Supplemental Information | Acquisition Description: The Photosystem II (PSII) photochemical efficiency (Yield PSII) was recorded at noon (ΔF/Fm') and at dusk (Fv/Fm) on corals from the species Orbicella faveolata. Measurements were recorded on corals used in a reciprocal transplant experiment and on random colonies. Data from three study sites are reported: Varadero at 3.5m depth (10°18’23.3”N, 75°35’08.0”W); Rosario at 12m depth (10°11'12.1"N, 75°44'43.0"W); and Cartagena Bay at 3m depth (10°18'5.80"N, 75°34'37.10"W). Varadero and Rosario were both source and destination sites; Cartagena Bay was only a destination site. The maximum quantum yield of PSII (Fv/Fm) was recorded at dusk and the effective quantum yield of PSII (ΔF/Fm’) at local noon during peak of sunlight exposure. Measurements were performed with a submergible Pulse Amplitud Modulated fluorometer (diving-PAM, Walz, Germany) on fragments used in a reciprocal transplant experiment and on colonies randomly distributed at similar depths compared to the transplant experiment. Three study sites with contrasting exposure to the Dique channel freshwater plume were considered: 1) Varadero reef at 3.5m depth close to the Dique channel mouth (10°18’23.3”N, 75°35’08.0”W), 2) Rosario reef at 12m depth as clear-control site located 21 km southwest of Varadero (10°11'12.1"N, 75°44'43.0"W), and 3) Cartagena Bay at 3m depth, the closest site to the Dique channel mouth (10°18'5.80"N, 75°34'37.10"W). The software WinControl-3 was used to operate and download the data from the diving-PAM. |
