attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson
attribute NC_GLOBAL acquisition_description String Sediments were collected and profiled immediately with voltammetric Hg/Au
microelectrodes deployed on a computer-controlled micromanipulator (Beckler et
al., 2016). Sediment pore waters were then extracted from the same core and
either preserved until analysis or analyzed immediately onboard ship. Sampling
and analyses were conducted immediately after sediment collection to minimize
artifacts from exposure to the atmosphere.

Sediment cores were obtained by a MC-800 multi-corer and profiled within 30
minutes with voltammetric Hg/Au microelectrodes deployed on a computer-
controlled micromanipulator. After profiling, sediments were immediately
sliced under N\u2082 atmosphere and pore waters extracted by centrifugation at
3000 rpm under N\u2082 atmosphere. Finally, pore waters were immediately
filtered (0.2 \u00b5M PSE Puradisc syringe filters, Whatman) under N\u2082
atmosphere and either preserved at -20C until analysis (Br\u207b,
NO\u2082\u207b, NO\u2083\u207b, SO\u2084\u00b2\u207b), preserved at 4C after
acidification (NH\u2084\u207a), dispensed directly into reagents for analysis
(Fe(II), Fed, Mnd, SPO\u2084\u00b3\u207b), or analyzed immediately (DIC, TA).
Br\u207b, NO\u2082\u207b, NO\u2083\u207b, and SO\u2084\u00b2\u207b were
measured by non-suppressed HPLC with UV detection (Beckler et al., 2014).
NH\u2084\u207a was measured spectrophopotmetrically by the indophenol blue
method (Strickland and Parsons, 1972), Fed and Fe(II) were measured by the
ferrozine method after addition or not of hydroxylamine (Stookey, 1970). Mnd
was measured by the porphyrin kinetic spectrophotometric method (Madison et
al., 2011) modified to account for dissolved Fe(II) interferences (Owings et
al., 2020). SPO\u2084\u00b3\u207b was measured spectrophotometrically using
the molybdate-blue method after natural color correction to avoid
interferences from dissolved silica and sulfides (Murphy and Riley, 1962). DIC
was measured by flow injection analysis with conductivity detection after
spiking samples with 10 mM ZnCl\u2082 to prevent dissolved sulfide
interferences (Hall and Aller, 1992). Finally, TA was measured by acid
titration in an open-cell with continuous pH measurements (Dickson et al.,
2007; Rassmann et al., 2016). All errors reported for the electrochemical
measurements represent the standard deviation of at least triplicate
measurements. Errors of all other parameters represent the analytical error
propagated from calibration curves, dilution, and instrumental drift.

Problem report: Some of the data are missing because pore water volumes were
too low to make all the measurements.

attribute NC_GLOBAL instruments_0_description String A High-performance liquid chromatograph (HPLC) is a type of liquid chromatography used to separate compounds that are dissolved in solution. HPLC instruments consist of a reservoir of the mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by high pressure pumping of the sample mixture onto a column packed with microspheres coated with the stationary phase. The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase.

attribute NC_GLOBAL instruments_2_description String An instrument that performs flow injection analysis. Flow injection analysis (FIA) is an approach to chemical analysis that is accomplished by injecting a plug of sample into a flowing carrier stream. FIA is an automated method in which a sample is injected into a continuous flow of a carrier solution that mixes with other continuously flowing solutions before reaching a detector. Precision is dramatically increased when FIA is used instead of manual injections and as a result very specific FIA systems have been developed for a wide array of analytical techniques.

attribute NC_GLOBAL projects_0_description String NSF Award Abstract:
Iron is a limiting nutrient in the world's oceans and plays a key role in regulating the growth of phytoplankton. The main sources of iron to the open ocean are the atmosphere, through wind-blown terrestrial dust, and the seafloor, through input from continental shelf sediments. While atmospheric inputs have been well-studied, the oceanic input of iron from sediments has only sparsely been measured and, as a result, the relative importance of the sediment-derived iron to the iron pool and, ultimately, primary productivity in the oceans is poorly understood. In this study, researchers will examine the chemical properties of sediment-derived iron in the oceans to assess its contribution to the iron used by phytoplankton. Results from this study will further our understanding of iron inputs to the ocean and their importance to ocean primary productivity. The project will contribute to the training of graduate students, as well as provide educational opportunities such as a day at sea for undergraduate students in engineering and physical science.
The atmosphere and continental margin sediments are the main source of the limiting nutrient iron (Fe) to the open ocean. Yet, the chemical form of iron from sediments has not been well examined and only quantified as reduced iron or the dissolved iron passing through 0.45 µm filters. The kinetics of iron oxygenation suggests it should precipitate rapidly in the overlying waters, challenging the view that sediments are important sources of iron for primary production. To establish whether the flux of iron from sediments has important implications for primary productivity, possibly rivaling atmospheric inputs, it is necessary to demonstrate that ferric iron originating in sediments is under the form of stable iron species with potential for a high residence time in the water column. The overall objective of this project is to test the hypotheses that iron fluxing across the sediment-water interface in continental margin sediments is dissolved under the form of organic-Fe(III) complexes and that the magnitude of the iron flux is influenced by the redox conditions in the overlying waters, the composition of the complexes, and the biogeochemical processes in the underlying sediments. To test these hypotheses, the flux and speciation of dissolved Fe(III) will be quantified in the sediments of the Carolina depocenter and the Gulf of Mexico, and the biogeochemical processes regulating the production and the flux of iron as a function of the redox regime of the environment will be determined using in situ measurements and state-of-the-art voltammetric and chromatographic techniques.
