attribute NC_GLOBAL acquisition_description String The Varadero Reef is located south-west of the Cartagena Bay close to the\nsouthern strait that connects the Bay to the Caribbean Sea in Colombia\n(10\\u00b018\\u201923.3\\u201dN, 75\\u00b035\\u201908.0\\u201dW). The Bay is a\nreceiving estuary from the Magdalena River through the Canal del Dique, a man-\nmade channel whose construction and operation dates back almost a century.\nThree study sites with contrasting light regimes were considered in order to\nevaluate the role of the light-environment perturbation associated with the\nDique channel freshwater plume on the photosynthetic performance of corals\nfrom Varadero: 1) Varadero reef at 3.5m depth close to the Dique channel mouth\n(10\\u00b018\\u201923.3\\u201dN, 75\\u00b035\\u201908.0\\u201dW), 2) Rosario reef at\n12m depth as clear-control site 21 km southwest from Varadero\n(10\\u00b011'12.1\\\"N, 75\\u00b044'43.0\\\"W), and 3) Cartagena Bay at 3m depth,\nthe closest\\u00a0 site to the Dique channel mouth and most turbid among the\nthree sites (10\\u00b018'5.80\\\"N, 75\\u00b034'37.10\\\"W).\n \nThe values of the photosynthetic efficiency (alpha) are expressed in umol O2\numol quanta-1, the compensating irradiance (Ec) in umol quanta m-2 s-1, the\nsaturating irradiance (Ek) in umol quanta m-2 s-1, the average respiration\nrate (R-avg) as well as the respiration pre- and post-illumination (R0 and Rf)\nare expressed in umol O2 m-2 s-1, and the net and gross maximum photosynthesis\nrates (Pmax(n) and Pmax(gross)) are expressed in umoles O2 m-2 s-1.\n \nPhotosynthetic parameters of corals were obtained from PE (photosynthesis vs.\nirradiance) curves conducted under laboratory conditions. A custom-made water-\njacket acrylic chamber with four independent hermetic compartments (~650 ml\neach) was used to run the PE curves, maintaining a constant temperature of 28\n\\u00b0C, close to natural conditions, with an external circulating water bath\n(Isotemp, Fisher Scientific). During each incubation, corals were submerged on\nfiltered seawater (0.45 \\u00b5m) under constant agitation by magnetic\nstirrers. Ten levels of irradiance between 0 and ~1400 \\u00b5mol quanta m-2\ns-1 were supplied at 10-min intervals with four 26 W LED bulbs (UL PAR38, LED\nWholesalers Inc, USA). The light intensity was controlled with a custom-made\nsoftware. The LEDs were operated in continuous mode with a multifunction I/O\ncard (USB-6001, National Instruments Corp., USA) to avoid potential artefacts\nrelated to the effect of different pulsating frequencies on photosynthesis.\nOxygen concentrations inside the compartments within the chamber were measured\nwith a 4-channel fiber optical oxygen meter system (FireSting, Pyroscience,\nGermany). The photosynthetic efficiency (\\u03b1), compensating irradiance\n(Ec), saturating irradiance (Ek), respiration rates (Rd), and maximum\nphotosynthetic rates (Pmax), were calculated from the light-limited and light-\nsaturated regions of the PE curves. Chlorophyll a (Chl a) content per unit of\ncoral surface area was determined after obtaining coral tissue slurries with\nthe help of an air gun connected to a scuba tank. Pigment extraction was\nperformed in acetone/dimethyl sulfoxide (95:5 vol/vol) after homogenizing the\nslurries with a Tissue-Tearor Homogenizer (BioSpec Inc, USA). Chl a density\nwas estimated spectrophotometrically with a modular spectrometer (Flame-T-UV-\nVIS, Ocean Optics Inc., USA). The specific absorption coefficient of Chl a\n(a*Chl a) was calculated using the equation: a*Chl a = (D675/\\u03c1) \\u00b7\nln(10), where D675 is the estimated absorbance value of corals at 675 nm,\ncalculated from reflectance (R) measurements as [D675 = log (1/R675)], and\n\\u03c1 is the pigment content per projected surface area (mg Chl a m-2).\n \nThe software Pyro Oxygen Logger was used to operate the fiber optical oxygen\nmeter system. The software OceanView was used to operate there modular\nspectrometer.

attribute NC_GLOBAL project String Varadero Reef
attribute NC_GLOBAL projects_0_acronym String Varadero Reef
attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nCoral 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.\nThis 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.
