The irradiance recorded synchronously onshore and underwater were used to estimate the variability of the light attenuation coefficient (Kd) resulting from temporal variation of the optical properties of water.&lt;/p&gt; &lt;p&gt;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,&amp;nbsp;2019-12-28]&lt;/p&gt; Methods and Sampling: &lt;p&gt;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&quot;N, 75°35’08.0&quot;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. The depth of the particular transplant site in Varadero is 3.5m.&lt;/p&gt; &lt;p&gt;Irradiance was monitored for one year (November 2016 - November 2017) at Varadero with cosine-corrected light sensors (Odyssey submersible PAR logger, Dataflow systems, New Zealand), previously cross-calibrated against a manufacturer-calibrated quantum sensor (LI-1400, LI-COR, USA). The light sensors were cleaned and downloaded periodically (every two months or less) to avoid biofouling. Data in which cumulative light signal loss was evident were discarded.&lt;/p&gt; &lt;p&gt;In order to estimate the variation of the optical properties of water resulting from the Dique plume dynamics, light data recorded underwater were compared with data simultaneously recorded by another sensor in a site onshore close to Varadero (Fig. 5). With this array, we were able to isolate the variations of irradiance associated with the plume from variations due to cloud coverage. The irradiance synchronously recorded by onshore and underwater loggers was used to estimate the variability of Kd based on the Lambert-Beer’s law: Kd = ln (Ez / E0) / -Z,&lt;/p&gt; &lt;p&gt;where Ez is the irradiance recorded underwater, E0 is the irradiance recorded onshore, and Z is the depth at which the underwater sensor was deployed in Varadero (3.5 m).

RAPID: Coral robustness: lessons from an &quot;improbable&quot; reef https://osprey.bco-dmo.org/project/717028 RAPID: Coral robustness: lessons from an &quot;improbable&quot; reef <p><em>NSF Award Abstract:</em><br /> 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.</p> <p>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.</p> Varadero Reef largerWorkCitation project eng; USA oceans -75.5856 -75.5856 10.3065 10.3065 2017-08-12 2017-11-28 Caribbean Sea (10°18’10”N, 75°34’ 55”W) 0 BCO-DMO catalogue of parameters from Irradiance and estimated light attenuation coefficient, Kd, underwater and onshore in Varadero Reef, 2017 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/786623.rdf Name: Date Units: unitless Description: <p>sampling date</p> http://lod.bco-dmo.org/id/dataset-parameter/786624.rdf Name: Time Units: unitless Description: <p>sampling time</p> http://lod.bco-dmo.org/id/dataset-parameter/786625.rdf Name: DateTimeLocal Units: unitless Description: <p>sampling date and time</p> http://lod.bco-dmo.org/id/dataset-parameter/786626.rdf Name: Irradiance_uw Units: micromol quanta meter^-2 second^-1 Description: <p>light intensity underwater</p> http://lod.bco-dmo.org/id/dataset-parameter/786627.rdf Name: Irradiance_onshore Units: micromol quanta meter^-2 second^-1 Description: <p>light intensity onshore</p> http://lod.bco-dmo.org/id/dataset-parameter/786628.rdf Name: Kd_est Units: meter^-1 Description: <p>estimated light attenuation coefficient Kd</p> http://lod.bco-dmo.org/id/dataset-parameter/786629.rdf Name: ISO_DateTime_UTC Units: unitless Description: <p>date and time formatted is ISO: yyyy-mm-ddTHH:MM:SSZ</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact 390683 https://darchive.mblwhoilibrary.org/bitstream/1912/25476/1/dataset-786608_reciprocal-transplant-expt-irradiance-and-light-attenuation-2017__v1.tsv download https://doi.org/10.1575/1912/bco-dmo.786608.1 download onLine dataset &lt;p&gt;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&quot;N, 75°35’08.0&quot;W).
