This was roughly along a N/S transect along ~145º West, between 59º North and 60.2º North and a few samples collected along an E/W transect between ~146º West and 145º West. Sample collection occurred during three research cruises in 2010 (7-9 April (CR2010-01), 5-7 May (CR2010-02), and 27-29 July (CR2010-04).&lt;/p&gt; &lt;p&gt;Samples below the surface were collected using 8 L externally closed Niskin bottles whose inner face was Teflon-coated, attached to Spectra (Dyneema) line, and triggered at depth using Teflon-lined messengers. Additionally, profiles of salinity, temperature, fluorescence, and turbidity were measured with a Seabird SBE16 CTD, deployed at the same time as the collection of the subsurface water samples. All water column profiles were carried out to within roughly 5 m of the maximum water depth, except at station 5, where the water depth was ~4000 m. Niskin bottles were processed in the shipboard clean lab within 3 hours or less of sample collection. Acid-washed 0.45 μm Pall Supor filters were used in the clean lab to filter the seawater samples collected using Niskin bottles, also under N₂ pressure. All trace metal samples were stored double-bagged in acid-cleaned low-density polyethylene bottles and acidified to pH 1.8 in the shipboard clean lab with Seastar™ concentrated HCl within 3 days of collection, then stored for &amp;gt;6 months prior to analysis.&lt;/p&gt; &lt;p&gt;Surface waters were sampled by underway pumping of seawater through Teflon-lined tubing using a technique adapted from that of Vink et al. (2000), with the intake positioned a few centimeters forward from, and mounted to, a PVC towfish towed ~2 meters (m) below the surface. Data from surface samples are available as a related dataset (BCO-DMO dataset 891941).&lt;/p&gt; &lt;p&gt;Filtered samples were analyzed for dissolved aluminum (Al) and unfiltered samples were analyzed for total dissolvable Al using Flow Injection Analysis (Resing and Measures 1994) using fluorescent detection of lumogallion. Samples exceeding 100 nanomolar (nM) were diluted with low-aluminum, low-manganese seawater to ensure linear response of the standard curve. Samples were assigned to a low, medium, or high standard curve depending on concentration. Low concentration samples were considered to be 0-20 nM, medium: 10-100, and high 100-2000 nM. Standards of 0, 1, 5, and 15 nM (low curve); 10, 50, 100 nM (medium curve); and 750 nM and 2000 nM (high curve) were analyzed in replicate. For the low curve, the detection limit was 0.79 nM, and 1 nM standards had a relative standard deviation (RSD) of 33% (n = 8). The minimum concentration of all samples analyzed was 3.7 nM; there were only four samples with concentrations less than 5 nM. The 5 nM standard had an RSD of 6% (n = 10), and the 15 nM standard had an RSD of 3% (n = 10). For the medium curve, the 10 nM standard had an RSD of 4% (n = 10), and the 50 nM and 100 nM standards had RSDs of 1%. The 750 nM and 2000 nM standards were measured to have a relative standard deviation &amp;lt;1%.&lt;/p&gt; &lt;p&gt;Filtered samples were analyzed for dissolved manganese (Mn) and unfiltered samples were analyzed for total dissolvable Mn according to the method of Resing and Mottl (1992), which uses spectroscopic detection of leuchomalachite green. A similar method to that described above was used to determine the accuracy of the wide spread of the data. Standards were run 10 times in succession to determine the daily precision. The 5 nM standard had a relative standard deviation of 3%, the 20 nM and 50 nM standards had RSDs of 1%. A sample collected during the campaign was used as an internal standard and analyzed at least daily, with a concentration determined to be 25.2 nM ± 0.7 (1 SD, n = 20). The limit of detection was determined by analyzing the lowest standard (0.52 nM) in replicate (SD = 0.86 nM). This value is 12% of the lowest sample analyzed.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Known Issues/Problems:&lt;/strong&gt;&lt;br /&gt; CTD data for April Station 5 does not extend to depth, and the CTD profile for April Station 3 was not collected.&lt;/p&gt; Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-1237011 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=1237011 completed John Crusius USGS Alaska Science Center at University of Washington, School of Oceanography Seattle WA USA jcrusius@usgs.gov pointOfContact Joseph A.

US GEOTRACES Pacific Section-Shipboard Al, Mn and Fe https://osprey.bco-dmo.org/project/670288 US GEOTRACES Pacific Section-Shipboard Al, Mn and Fe <p><em>Description from NSF award abstract:</em><br /> The 2013 GEOTRACES Eastern Pacific Zonal transect cruise will transit from the highly productive coastal upwelling region off Peru to the stratified oligotrophic waters of the South Pacific subtropical gyre on its way to Tahiti. A range of subsurface oxygen depleted water and sedimentary inputs from the Peru margin will be encountered, as well as hydrothermal vents at 15°S on the East Pacific Rise (EPR). Scientists from the University of Washington and Old Dominion University plan to analyze seawater samples for dissolved and total-dissolvable aluminum (Al), manganese (Mn), and iron (Fe) in water column samples. The dissolved Al, Mn, and Fe in samples from the upper water column (&lt;1000 m depth) will be analyzed onboard to ensure samples being collected are uncontaminated, as well as samples from west of the EPR at hydrothermal plume depths. The shipboard analyses will be augmented by shore-based analyses of water column samples from all depths, as well as analyses of total-dissolvable Al, Mn, and Fe, which will complement the direct analyses of particulate metals undertaken by other GEOTRACES investigators. Results will be used to test the following hypotheses concerning the sources and cycling of Al, Mn and Fe in the ocean: (1) when Aeolian inputs are relatively constant, dissolved Al concentrations in surface waters vary as a function of biological production; (2) concentration maxima of dissolved Al, Mn, and Fe in subsurface waters of the Eastern Pacific oxygen minimum zone are the result of lateral transport from the continental margin by means of resuspension and remobilization; and (3) values about ambient levels with conservative behavior will be encountered in the neutrally buoyant plume about the East Pacific Rise ridge crest for dissolved Fe and Al.</p> <p>As regards broader impacts, results from the study would be disseminated to the public via lectures, the internet, and press releases. One graduate and one undergraduate student from the University of Washington would be supported and trained as part of this project.</p> EPZT Shipboard Al Mn Fe largerWorkCitation project eng; USA oceans Northern Gulf of Alaska -145.2 -144.916 59.0767 60.1914 2010-04-07 2010-07-29 Eastern South Pacific Ocean 0 BCO-DMO catalogue of parameters from Dissolved aluminum (Al) and manganese (Mn) and total dissolvable Al and Mn from subsurface water samples collected during three cruises in 2010 in the northern Gulf of Alaska Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/892105.rdf Name: Cruise Units: unitless Description: <p>Cruise number</p> http://lod.bco-dmo.org/id/dataset-parameter/892106.rdf Name: Station Units: unitless Description: <p>Station number (1-5)</p> http://lod.bco-dmo.org/id/dataset-parameter/892107.rdf Name: Depth Units: meters (m) Description: <p>water depth</p> http://lod.bco-dmo.org/id/dataset-parameter/892108.rdf Name: ISO_DateTime_UTC Units: unitless Description: <p>Station timestamp (UTC) in ISO 8601 format</p> http://lod.bco-dmo.org/id/dataset-parameter/892109.rdf Name: Latitude_degN Units: degrees North Description: <p>Sample latitude</p> http://lod.bco-dmo.org/id/dataset-parameter/892110.rdf Name: Longitude_degE Units: degrees East Description: <p>Sample longitude</p> http://lod.bco-dmo.org/id/dataset-parameter/892111.rdf Name: DAl Units: nanomolar concentration (nM) Description: <p>Dissolved Aluminum</p> http://lod.bco-dmo.org/id/dataset-parameter/892112.rdf Name: TDAl Units: nanomolar concentration (nM) Description: <p>Total Dissolvable Aluminum</p> http://lod.bco-dmo.org/id/dataset-parameter/892113.rdf Name: DMn Units: nanomolar concentration (nM) Description: <p>Dissolved Manganese</p> http://lod.bco-dmo.org/id/dataset-parameter/892114.rdf Name: TDMn Units: nanomolar concentration (nM) Description: <p>Total Dissolvable Manganese</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact 9716 https://darchive.mblwhoilibrary.org/server/api/core/bitstreams/f18da9ae-e2ec-4c46-a280-0c2819489c3f/content download https://doi.org/10.26008/1912/bco-dmo.891918.1 download onLine dataset &lt;p&gt;Data were collected from the Northern Gulf of Alaska, along the shelf and slope from the mouth of the Copper River to about 50 kilometers (km) past the shelf break.

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.
