attribute NC_GLOBAL acquisition_description String In May 2015 and 2016, skeletal cores were collected from 39 colonies of\nSiderastrea siderea and 31 colonies of Pseudodiploria strigosa at four pairs\nof inner-outer reef sites spanning the Florida Keys Reef Tract. All cores were\nextracted from the vertical growth axis of each coral colony using a CS Unitec\nmodel 2 1335 0010 hydraulic drill affixed with hollow extension rods and a 5\ncm diameter wet diamond core bit. Collected cores were then stored in capped\nPVC tubes filled with 100% EtOH and transported to the University of North\nCarolina at Chapel Hill where they were air dried in preparation for\nsclerochronology development. To assess coral skeletal growth histories, all\ncores were scanned using X-ray computed tomography (CT) on a Siemens Biograph\nCT scanner at the Biomedical Research Imaging Center, University of North\nCarolina at Chapel Hill. Coral cores were oriented lengthwise in rows of 4 to\n5 on the scanning table, and equipment parameters were set to 120 kV, 250 mAs\nand 0.6 mm slice thickness with images reconstructed at 0.1 mm increments\nusing the H70h \\u201cVery Sharp Spine\\u201d window.\n \nAll images were exported from the CT scanner as DICOM files, which were then\n3-dimensionally reconstructed using the open-access Horos v2.0.2 medical image\nviewing software. High- and low-density bands were visualized using a 10-mm\nthick \\u2018Mean\\u2019 projection oriented as a rectangular prism through the\ncenter of each core. All boundaries between semiannual density bands were\ndelineated manually and three sets of linear transects were drawn down the\nlength of the cores using the Region of Interest (ROI) tool in Horos. Note,\neach set of transects was drawn within the exothecal space between corallite\nwalls in order to standardize density measurements and to avoid aberrant\ndensity spikes in areas where the transect may otherwise have crossed a high-\ndensity corallite wall. Density and calcification measurements are therefore\nlower than would be expected if all features of the skeletal architecture were\ntaken into account. Additionally, it has been shown that individual colonies\nmay vary in their timing of high- and low-density band deposition due to\nintraspecific differences in tissue thickness and morphology (Barnes and\nLough, 1996; Carricart-Ganivet, 2013). Thus, to approximate a consistent time\nstandard between cores, we begin all chronologies at the top of the first\nfully deposited density band beneath the band of terminal growth. By-pixel\ndensity measurements were extracted from linear transects and average density\nwas calculated for each semiannual high- and low-density band. Following\nDeCarlo et al (2015), nine coral standards of known density were included in\nevery scanning session to convert density measurements from CT Hounsfield\nunits to g cm-3. Average density of each standard was assessed in Hounsfield\nunits using Horos and a standard curve was created for all cores scanned in\nthe corresponding session. Linear extension (cm) was measured in Horos as the\nwidth of each annual density band couplet, and calcification (g cm-2 yr-1) was\ncalculated as the product of density and linear extension.\n \nNote, because cores were collected in subsequent years, the most recent year\nof growth (2015) was not included for cores collected in 2016 in order to keep\nthe beginning of chronologies uniform throughout.\n \nAnalysis was based on previously published methods in Castillo et al (2011),\nCastillo et al (2012).\n \n\\u00a0

attribute NC_GLOBAL instruments_0_description String A core drill is a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core.\n\nCore drills are used frequently in mineral exploration where the coring may be several hundred to several thousand feet in length. The core samples are recovered and examined by geologists for mineral percentages and stratigraphic contact points. This gives exploration companies the information necessary to begin or abandon mining operations in a particular area.

attribute NC_GLOBAL project String Thermal History and Coral Growth
attribute NC_GLOBAL projects_0_acronym String Thermal History and Coral Growth
attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:\nRising global ocean surface temperatures have reduced coral growth rates, thereby negatively impacting the health of coral reef ecosystems worldwide. Recent studies on tropical reef building corals reveal that corals' growth in response to ocean warming may be influenced by their previous seawater temperature exposure - their thermal history. Although these recent findings highlight significant variability in coral growth in response to climate change, uncertainty remains as to the spatial scale at which corals' thermal history influences how they have responded to ocean warming and how they will likely respond to predicted future increases in ocean temperature. This study investigates the influence of thermal history on coral growth in response to recent and predicted seawater temperatures increases across four ecologically relevant spatial scales ranging from reef ecosystems, to reef communities, to reef populations, to an individual coral colony. By understanding how corals have responded in the past across a range of ecological scales, the Principal Investigator will be able to improve the ability to predict their susceptibility and resilience, which could then be applied to coral reef conservation in the face of climate change. This research project will broaden the participation of undergraduates from underrepresented groups and educate public radio listeners using minority voices and narratives. The scientist will leverage current and new partnerships to recruit and train minority undergraduates, thus allowing them to engage high school students near field sites in Florida, Belize, and Panama. Through peer advising, undergraduates will document this research on a digital news site for dissemination to the public. The voice of the undergraduates and scientist will ground the production of a public radio feature exploring the topic of acclimatization and resilience - a capacity for stress tolerance within coral reef ecosystems. This project will provide a postdoctoral researcher and several graduate students with opportunities for field and laboratory research training, teaching and mentoring, and professional development. The results will allow policy makers from Florida, the Mesoamerican Barrier Reef System countries, and several Central American countries to benefit from Caribbean-scale inferences that incorporate corals' physiological abilities, thereby improving coral reef management for the region.\nCoral reefs are at significant risk due to a variety of local and global scale anthropogenic stressors. Although various stressors contribute to the observed decline in coral reef health, recent studies highlight rising seawater temperatures due to increasing atmospheric carbon dioxide concentration as one of the most significant stressors influencing coral growth rates. However, there is increasing recognition of problems of scale since a coral's growth response to an environmental stressor may be conditional on the scale of description. This research will investigate the following research questions: (1) How has seawater temperature on reef ecosystems (Florida Keys Reef Tract, USA; Belize Barrier Reef System, Belize; and Bocas Del Toro Reef Complex, Panama), reef communities (inshore and offshore reefs), reef populations (individual reefs), and near reef colonies (individual colonies), varied in the past? (2) How has seawater temperature influenced rates of coral growth and how does the seawater temperature-coral growth relationship vary across these four ecological spatial scales? (3) Does the seawater temperature-coral growth relationship forecast rates of coral growth under predicted end-of-century ocean warming at the four ecological spatial scales? Long term sea surface temperature records and small-scale high-resolution in situ seawater temperature measurements will be compared with growth chronologies for the reef building corals Siderastrea siderea and Orbicella faveolata, two keystone species ubiquitously distributed throughout the Caribbean Sea. Nutrients and irradiance will be quantified via satellite-derived observations, in situ measurements, and established colorimetric protocols. Field and laboratory experiments will be combined to examine seawater temperature-coral growth relationships under recent and predicted end-of-century ocean warming at four ecologically relevant spatial scales. The findings of this study will help us bridge the temperature-coral growth response gap across ecologically relevant spatial scales and thus improve our understanding of how corals have responded to recent warming. This will lead to more meaningful predictions about future coral growth response to climate change.
