A16N Particulate trace element concentrations Dataset Description: <p>Particulate trace element concentrations along CLIVAR A16N in 2013.</p>
<p>Note that related data from 2003 are available here:&nbsp;<a href="https://www.bco-dmo.org/dataset/3702" target="_blank">https://www.bco-dmo.org/dataset/3702</a></p> Methods and Sampling: <p>Seawater samples were collected from the surface ocean to depths of 750–1000 m, then sub-sampled for suspended particulate matter under trace-element-clean conditions (see Measures et al., 2008 for details). Briefly, suspended particulate matter samples were collected by pressurizing GO-FLO bottles with &lt;10 psi filtered, compressed air. Samples were filtered through acid-cleaned 0.4 um polycarbonate filters (Nuclepore) in polypropylene holders. Acid-cleaned backing filters of mixed cellulose esters were used to ensure even loading on sample filters.&nbsp; Samples were rinsed while on the filter holders with 15–20 mL deionized (DI) water adjusted to pH 8 with ammonium hydroxide from the edges to the center, with a low vacuum applied to avoid loss or re-distribution of particles. Filtration was started approximately 30 to 60 minutes after water samples were collected and was generally completed within 60 minutes.</p>
<p>Particulate trace element concentrations were determined by energy-dispersive X-ray fluorescence (ED-XRF) using a thin film technique described by Feely et al. (1991). An optical subsample of each filter was analyzed on a Thermo Fisher Quant’X equipped with a Rhodium Target X-Ray tube and an electronically cooled, lithium-drifted solid state detector. X-rays for primary sample excitation were filtered for optimum control of peak-to-background ratios. Standards for calibration consisted of commercial thin film standards (MicroMatter), geochemical reference sample material MAG-1 (Gladney and Roelandts, 1988) finely ground and loaded onto polycarbonate filters (Feely et al., 1991), and a series of standards prepared using a modification of the method reported by Holynska and Bisiniek (1976) using sodium diethyldithiocarbamate (NaDDTC) to quantitatively precipitate trace metals from a solution of known concentration. These standards were prepared using a 1% NaDDTC solution that was added to trace metal solutions at pH 4 with a ligand-to-metal ratio of 4:1. The resulting precipitate was filtered over an acid-cleaned, 0.4 um polycarbonate Nuclepore filter. Procedural blanks were made by addition of a NaDDTC solution to a sample of acidified DI water followed by filtration. MicroMatter and MAG-1 standards were used to create individual standard curves for all elements; standard curves for Fe and Mn also included NaDDTC standards.&nbsp;</p>
<p>Four different excitation conditions, all conducted under a vacuum atmosphere, were used for sample analysis and are detailed along with minimum determination limits (MDL) in Table 1. MDLs are defined as 3 times the square root of the background intensity measured from a standard of known concentration:</p>
<p>MDL = ( 3 * √Ib)/(Ip/conc)&nbsp;&nbsp; &nbsp;</p>
<p>where&nbsp;Ib&nbsp;is the background intensity,&nbsp;Ip&nbsp;is the peak intensity, and&nbsp;conc&nbsp;is the concentration of the standard. MicroMatter standards were used to calculate MDLs.&nbsp;</p>

Collaborative Research: Trace Metal Deposition And Cycling In The North Atlantic On The 2013 CLIVAR/Repeat Hydrography A16N Expedition
<p><em>Description from NSF award abstract:</em><br />
Dr. Joseph Resing of the Joint Institute for the Study of the Atmosphere and the Ocean, Pacific Marine Environmental Laboratory, University of Washington and Dr. William Landing of Florida State University have proposed an ambitious field study to conduct trace metal sampling on the CLIVAR/CO2 Repeat Hydrography section A16N in the Atlantic Ocean in 2013. This field program will provide a valuable opportunity to elucidate aerosol-water column coupling, and possible decadal variability, for selected trace metals (Fe, Al, and others) and biogenic calcium carbonate. In addition to examining important questions regarding the nature of the response of trace element distributions in the water column to external dust input, these investigators will gain further insight into the issue of temporal and spatial changes in trace metal distributions through comparison with other field programs, most notably the international GEOTRACES program. With regard to the broader significance of this study, results from this large expedition will generate multiple national and international collaborations, contribute positively to the education and training of a graduate student and a postdoctoral fellow, and be of broad interest to the ocean sciences community.</p>

PI Supplied Instrument Name: CTD PI Supplied Instrument Description:Used to collect environmental data Instrument Name: CTD - profiler Instrument Short Name: Instrument Description: The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.
This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934. Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/130/
