attribute NC_GLOBAL acquisition_description String DIC and TA\n \nMeasure of DIC using NDIR method and of TA using Gran titration. DIC and TA\nwere measured using the instruments from Apollo Scitech Inc. Briefly, for DIC\nanalysis, samples were analyzed at room temperatures. Each seawater sample\n(0.5 mL) was acidified using phosphoric acid and the evolved CO2 gas was\nextracted and carried by pure N2 gas to an infrared CO2 detector (Li-Cor 6262)\nfor quantification. TS was determined on 25 mL seawater sample by\npotentiometric titration, using 0.1 M hydrochloric acid and an open-cell\ntitration system. All TA samples were analyzed in pre-thermostated (25\n\\u00b0C) glass cells. For each DIC or TA sample, sub-samples were sequentially\nanalyzed 2 or 3 times until we obtained two replicates with a precision within\n0.1%. The average of the two values is reported. The precision of both the TA\nand DIC measurements was +/- 2 umol/kg. The accuracies of the TA and DIC\nmeasurements were determined by routine analysis of certified reference\nmaterial (CRM) provided by A. G. Dickson, Scripps Institution of Oceanography.\n \nDO_spec\n \nWinkler titration was used for DO analysis. Samples were drawn from Niskin\nbottles directly into 60 ml BOD bottles and pickled using manganese chloride\nand sodium iodide/sodium hydroxide. Iodine liberated by acidifying pickled\nsample was then measured spectrophotometrically using Genesis 30 (Thomas\nScientific) spectrophotometer at 466 nm. Blank absorbance from sample\nturbidity was obtained by adding a few drops of sodium thiosulfate to the\nsample solution and subtracted from sample absorbance. Calibration was\nperformed by spiking known amounts of potassium iodate. Error on DO was from\nthe uncertainty of measuring absorbance (0.001), which is equivalent of 0.7\nuM. Samples which had blank absorbance exceeding 5% of sample absorbance were\nflagged.\n \npH_elec\n \npH samples were drawn in 60 ml glass bottles and temperature equilibrated at\n25 oC. An Orion Combination electrode connected to a pH meter (Orion Star\nA211) was used to measure the potential (EMF, mV) generated by the H+ ions.\nEMF was calibrated using three NBS buffer solutions at pH 4.01, 7.0, and 10.01\npurchased from Fisher Scientific. Probe was kept immersed in the sample until\nthe EMF stabilized. Two EMF readings at a difference of 1 minute were obtained\nfor each sample and average value used with calibration to calculate the pH.\nPrecision on pH is estimated from the standard deviation of the mean of two\nEMF readings. Samples where such deviation exceeded 0.16% of the mean EMF are\nflagged.\n \npH_spec\n \nDiscrete sample pH_spec was measured spectrophotometrically at 25 degrees\nCelsius on the total pH scale using purified M-Cresol Purple purchased from R.\nByrne at the University of South Florida [Clayton and Byrne, 1993; Liu et al.,\n2011]. The spectrophotometric pH (25 oC, total scale) was calculated from the\nratio of the measured absorbances of mCP at wavelengths l2 = 578 nm and l1 =\n434 nm following the dissociation constants proposed by Liu et al 2011].\n \nSampling and analytical procedures:\n \nMeasure of DIC using NDIR method and of TA using Gran titration.

attribute NC_GLOBAL project String nGOMx acidification
attribute NC_GLOBAL projects_0_acronym String nGOMx acidification
attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nOcean acidification (OA) refers to the lowering of ocean pH (or increasing acidity) due to uptake of atmospheric carbon dioxide (CO2). A great deal of research has been done to understand how the open ocean is influenced by OA, but coastal systems have received little attention. In the northern Gulf of Mexico (nGOM) shelf region, pH in bottom waters can measure up to 0.45 units less than the pH of the pre-industrial surface ocean, in comparison to the 0.1 overall pH decrease across the entire ocean. Carbonate chemistry in the ocean is greatly influenced by even small changes in pH, so these seemingly minor changes lead to much greater impacts on the biology and chemistry of the ocean. The researchers plan to study coastal OA in the nGOM, a region subject to high inputs of nutrients from the Mississippi River. These inputs of anthropogenic nitrogen mostly derived from fertilizers leads to increased respiration rates which decreases oxygen concentrations in the water column to the point of hypoxia in the summer. This study will inform us how OA in coastal waters subject to eutrophication and hypoxia will impact the chemistry and biology of the region. The researchers are dedicated to outreach programs in the Gulf and east coast regions, interacting with K-12 students and teachers, undergraduate/graduate student training, and various outreach efforts (family workshops on OA, lectures for the public and federal, state, and local representatives). Also, a project website will be created to disseminate the research results to a wider audience.\nIncreased uptakes of atmospheric carbon dioxide (CO2) by the ocean has led to a 0.1 unit decrease in seawater pH and carbonate mineral saturation state, a process known as Ocean Acidification (OA), which threatens the heath of marine organisms, alters marine ecosystems, and biogeochemical processes. Considerable attention has been focused on understanding the impact of OA on the open ocean but less attention has been given to coastal regions. Recent studies indicate that pH in bottom waters of the northern Gulf of Mexico (nGOM) shelf can be as much as 0.45 units lower relative to pre-industrial values. This occurs because the acidification resulting from increased CO2 inputs (both atmospheric inputs and in-situ respiration) decreases the buffering capacity of seawater. This interactive effect will increase with time, decreasing summertime nGOM bottom-water pH by an estimated 0.85 units and driving carbonate minerals to undersaturation by the end of this century. Researchers from the University of Delaware and the Louisiana Universities Marine Consortium will carry out a combined field, laboratory, and modeling program to address the following questions. (1) What are the physical, chemical, and biological controls on acidification in coastal waters impacted by the large, nutrient-laden Mississippi River?; (2) What is the link between coastal-water acidification, eutrophication, and hypoxia; (3) How do low pH and high CO2 concentrations in bottom waters affect CO2 out-gassing during fall and winter and storm periods when the water column is mixed?; and (4) What are the influences of changing river inputs under anthropogenic forcing on coastal water acidification? Results from this research aim to further our understanding of the processes influencing ocean acidification in coastal waters subject to eutrophication and hypoxia both in the GOM and river-dominated shelf ecosystems globally.
