attribute	NC_GLOBAL	acquisition_description	String	The Photosystem II (PSII) photochemical efficiency (Yield PSII) was recorded at noon (\u0394F/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.\u00a0Data from three study sites are reported: Varadero at 3.5m depth (10\u00b018\u201923.3\u201dN, 75\u00b035\u201908.0\u201dW); Rosario at 12m depth (10\u00b011'12.1\"N, 75\u00b044'43.0\"W); and Cartagena Bay at 3m depth (10\u00b018'5.80\"N, 75\u00b034'37.10\"W).\u00a0Varadero and Rosario were both source and destination sites; Cartagena Bay was only a destination site.\u00a0 The maximum quantum yield of PSII (Fv/Fm) was recorded at dusk and the effective quantum yield of PSII (\u0394F/Fm\u2019) 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\u00b018\u201923.3\u201dN, 75\u00b035\u201908.0\u201dW), 2) Rosario reef at 12m depth as clear-control site located 21 km southwest of Varadero (10\u00b011'12.1\"N, 75\u00b044'43.0\"W), and 3) Cartagena Bay at 3m depth, the closest site to the Dique channel mouth (10\u00b018'5.80\"N, 75\u00b034'37.10\"W). The software WinControl-3 was used to operate and download the data from the diving-PAM.

attribute	NC_GLOBAL	projects_0_description	String	NSF Award Abstract: Coral reefs provide invaluable services to coastal communities, but coral populations worldwide are in a state of unprecedented decline. Studying resilient reefs is of primary importance for coral conservation and restoration efforts. A unique natural experiment in coral resilience to stress has been playing out in Cartagena Bay, Colombia since the Spanish conquistadors diverted the Magadalena River into the Bay in 1582. Varadero Reef at the southern mouth of the Bay has survived centuries of environmental insults and changing conditions with up to 80% coral cover. This reef provides an ideal system to test biological robustness theory. Given that Varadero is a highly perturbed system, we hypothesize that while likely more robust to perturbation than nearby pristine reefs, it will be less physiologically efficient. Some of the large star coral colonies (Orbicella faveolata) at this site have existed since before the construction of the Canal del Dique. These coral specimens contain invaluable information regarding the conditions of the Magdalena River wathershed and its construction in the XIV century. Changes in turbidity of the plume associated with the urban industrial and agricultural development of Colombia can be documented as variations in calcification rates and changes in the microstructure of the skeleton. The Colombian government has announced the approval for the construction of a shipping channel that will go right over this reef, with the goal to start dredging as early as Fall 2016 or early 2017. The RAPID funding mechanism would enable immediate collection of data and information of why this reef has survived centuries of environmental stress that can shed light on what genotype combinations of coral and its microbial constituents will fare better in similar conditions at other reef locations around the world. Coral reef conservation biology will benefit from this study by generating data for the development of stress diagnostic tools to identify resilient corals. This project will help broaden participation in science by training a diverse cohort of students to work effectively in the global arena while fostering productive collaborations with several Colombian researchers and educational institutions. Students will also gain cultural empathy and sensitivity through direct engagement with the members of society who are most directly impacted by coral reef degradation (e.g. fishermen). Student researchers from Penn State University will work alongside their Colombian counterparts to develop a series of bilingual blog posts to record the cultural and scientific aspects of this project's research expeditions. The blog postings will be submitted for wide dissemination to the Smithsonian's Ocean Portal where Penn State students have published in the past. An educational coral kit developed by the Medina Lab and extensively tested in schools in the US has been translated into Spanish and will be used in local schools in Cartagena and vicinities. All expedition data and metadata will be incorporated into the Global Coral Microbiome Project's interactive web portal, a responsive outreach tool allows researchers, students and/or teachers to access a wealth of information about every coral colony we sample and to virtually explore coral reefs around the world from any internet-enabled device. This research will generate information to understand functional traits related to symbioses stability under different perturbation regimes. Comparative analyses of microbiome modifications generated during the reciprocal transplantation will allow us to document possible differential responses of the holobionts to acute and chronic stressors relative to corals not exposed to significant levels of perturbation. The development of local bio-optical models of coral calcification and the characterization of the coral holobiont will permit the distinction between the effects in calcification attributed to local turbidity from those that can be ;attributed to differences in host genotype and/or microbial community composition and function. The information recorded in coral skeletons can be used to reconstruct the rates of agricultural, industrial and urban development of Colombia through the last 5 centuries as changes in the turbidity of the effluent of the Magdalena River.
