attribute NC_GLOBAL acquisition_description String Coral cores (n57) were collected in July 2013 from the shallow reef at\nKahekili in Kaanapali, West Maui, Hawaii, from scleractinian Porites lobata\n(Figure 1) in water depths of between 1 and 3 m and in the vicinity of\nbrackish SGD \"seeps\" near Kahekili Beach Park (Glenn et al., 2013),\napproximately 0.5 km southwest of the LWRF (Table 1). All cores were collected\nfrom living Porites spp., except for adjacent to the seep where the coral\ncolony was dead upon collection. Colonies were selected based on several\ncriteria including distance from shore, distance from seep, coral shape, and\nwater depth. Metrics of coral reef health (bioerosion,calcification, and\ngrowth rate) were quantified at the Woods Hole Oceanographic\nInstitution\\u2019s CT Scanning Facility (Crook et al., 2013) where CT scan\nimages (supporting information Figure S1) were used to calculate the\nproportion of the skeleton eroded (>1 mm boring diameter) by boring\norganisms and calculated as the total volume of CaCO3 removed relative to the\ntotal volume of the individual Porites coral core (Barkley et al., 2015;\nDeCarlo et al., 2015) using coral CT (DeCarlo & Cohen, 2016). The average\ngrowth rate reported in this study is the average linear extension rate and\nrespective standard deviation for the length of cores analyzed per site.\nPearson correlation coefficients and respective p values were calculated in\nExcel. Significance levels were tested at the 95% and 90% confidence level.\nThe number of years for analysis ranged from the upper 10\\u201326 years and\nwas calculated as linear extension (mm) per year. The range (i.e., length of\ncore analyzed) reflects the fact that the quality/preservation of banding was\nnot consistent across the collection sites due to differences in boring and\nerosion (supporting information Figure S1). In comparison to measured\nbioerosion rates, predicted bioerosion rates were calculated using the\nequation from DeCarlo et al. (2015) where bioerosion rate5211.96 *\nXarag143.52. Coral life spans were calculated based on annual growth rate and\ncore length. Coral life span for the dead specimen was determined by comparing\nbomb-derived radiocarbon (14C) values measured at five depth intervals to\nreference bomb-curves from Hawaii (Andrews et al., 2016). Samples were\nprepared for Accelerator Mass Spectrometry (AMS) radiocarbon(14C) dating at\nthe National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS) facility.\n \nCoral nitrogen isotope (d15N) values were determined by collecting skeletal\nmaterial (\\u0003300 mg) from the upper 4.0\\u20135.6 mm of growth.\nApproximately 18 mg of material was placed into tin capsules with an\napproximately equivalent mass of vanadium oxide (V2O5) catalyst to ensure\ncomplete combustion for analysis using a Costech elemental\nanalyzer\\u2014Isotope Ratio Mass Spectrometry (EA-IRMS) at the University of\nCalifornia at Santa Cruz and the USGS Stable Isotope Lab to determine d15N\ncomposition. Analytical uncertainty of0.16&is reported based on replicate\nanalysis of the international nitrogen standard, acetanilide.\n \nSampling for water at the primary seep site and in adjacent coastal waters was\nconducted in September 2014 and March 2016. In 2014, sampling of the submarine\nsprings was conducted using a piezometer point directly inserted into the\nprimary seep site (Swarzenski et al., 2012) and a 12 V peristaltic pump during\nboth high and low tide (supporting information Table S1). At each sampling\nsite, the salinity and temperature of the seep water and bottom water was\nrecorded using calibrated YSI multiprobes. Seawater sampling in March 2016 was\nconducted near the coral sites every 4 h over a 6 day period for nutrients and\ncarbonate chemistry variables. A peristaltic pump was used to pump seawater\nfrom the seafloor and temperature and salinity were recorded using a\ncalibrated YSI multimeter. In situ temperatures were also recorded\nfromSolonist CTD Divers installed at each sampling tube (Prouty et al., 2017).

attribute NC_GLOBAL projects_0_description String Text from the NSF award abstract:\nHuman carbon dioxide emissions are causing measureable changes in ocean conditions. Many of these changes negatively affect coral reef ecosystems, reducing their ability to provide food, arable land, tourist destinations and coastline protection for hundreds of millions of people worldwide. This project focuses on the effects of enhanced stratification, caused by ocean warming, on the growth of reef-building corals across the Caribbean and Bermuda. Enhanced stratification impacts primary productivity which generates food for corals. Initial data generated by the investigators suggest that Atlantic coral growth has declined in the last 5 decades in response to these changes. A laboratory-based experiment is designed to test this hypothesis. If verified, the projected decline in Atlantic primary productivity through the 21st century could potentially rival and will certainly exacerbate the effects of warming and ocean acidification on coral reef ecosystems across the North Atlantic. Support is provided for graduate research, and undergraduate participation is facilitated through the Woods Hole Oceanographic Institution Summer Fellowship and the Bermuda Institute of Ocean Sciences-Princeton Environmental Institute Summer Internship Programs. The results will be presented at national and international meetings and disseminated in a timely manner through peer-reviewed publications. All data produced through this program will be archived in the Biological and Chemical Oceanographic Data Management Office.\nAnthropogenic climate change has emerged as a principle threat to coral reef survival in the 21st century. In addition to ocean warming and acidification, global climate models project enhanced stratification of the upper oceans through the 21st century and a consequent decline in productivity, by up to 50%, in the North Atlantic. This project employs controlled laboratory manipulation experiments to test the link between productivity and growth of the dominant reef-building corals across the Caribbean and Bermuda. Preliminary data generated by the investigators, including multi-decade long coral growth histories and nitrogen isotope ratios of coral tissue and skeleton, suggest that coral growth across the region has declined over the past 50 years in response to productivity changes already underway. If the link between ocean circulation, productivity decline, and coral growth is verified, the projected 21st century decline in productivity could rival and will certainly exacerbate the effects of warming and ocean acidification on North Atlantic coral reef ecosystems.
