GP16 Dissolved REEs - OSU Dataset Description: Methods and Sampling: <p>Samples were filtered, acidified, and split at sea. Samples were collected by Niskin bottle and the towed GeoFish. Refer to the EPZT cruise report&nbsp;for more information on cruise operations (<a href="http://dmoserv3.whoi.edu/data_docs/GEOTRACES/EPZT/GT13_EPZT_ODFReport_All.pdf" target="_blank">http://dmoserv3.whoi.edu/data_docs/GEOTRACES/EPZT/GT13_EPZT_ODFReport_All.pdf</a>).&nbsp;</p>
<p>We prepared our 5L split for neodymium isotopic analysis following Shabani et al. (1992). Samples were pH-adjusted to pH ~3.5, then pumped through 300 µl of HDEHP in a C18 cartridge to capture REEs. Rare earth elements were eluted from the cartridge using 6M HCl, then Nd was isolated using sequential chromatographic columns: AG50-X8 (BioRad) and Ln-Spec (Eichrom). Neodymium isotopic measurements were made at Lamont-Doherty Earth Observatory (Palisades, NY) using a Thermo Neptune multicollector ICP-MS.</p>
<p>For REE concentrations we removed an aliquot after pH-adjustment of each sample. Sample methodology is described in Behrens et al. (2006), as Lab #3. We preconcentrated 20 ml of sample offline using a SeaFast PICO system (ESI), then analysed the resulting solution at Oregon State University (Corvallis, OR) using a Thermo X-Series II ICP-MS.</p>
<p>Problem Report: Cerium measurements yielded questionable data during a couple of run days, these data are indicated using IODE quality flag 3– Questionable Data. Sample gaps in REE concentrations are due to analytical error during pre-concentration, sample gaps in Nd isotope data are due to insufficient quantity of Nd to make a measurement.</p>

U.S. GEOTRACES
GEOTRACES is a SCOR sponsored program; and funding for program infrastructure development is provided by the U.S. National Science Foundation.
GEOTRACES gained momentum following a special symposium, S02: Biogeochemical cycling of trace elements and isotopes in the ocean and applications to constrain contemporary marine processes (GEOSECS II), at a 2003 Goldschmidt meeting convened in Japan. The GEOSECS II acronym referred to the Geochemical Ocean Section Studies To determine full water column distributions of selected trace elements and isotopes, including their concentration, chemical speciation, and physical form, along a sufficient number of sections in each ocean basin to establish the principal relationships between these distributions and with more traditional hydrographic parameters;
* To evaluate the sources, sinks, and internal cycling of these species and thereby characterize more completely the physical, chemical and biological processes regulating their distributions, and the sensitivity of these processes to global change; and
* To understand the processes that control the concentrations of geochemical species used for proxies of the past environment, both in the water column and in the substrates that reflect the water column.
GEOTRACES will be global in scope, consisting of ocean sections complemented by regional process studies. Sections and process studies will combine fieldwork, laboratory experiments and modelling. Beyond realizing the scientific objectives identified above, a natural outcome of this work will be to build a community of marine scientists who understand the processes regulating trace element cycles sufficiently well to exploit this knowledge reliably in future interdisciplinary studies.

U.S. GEOTRACES East Pacific Zonal Transect (GP16)
http://www.geotraces.org/
U.S. GEOTRACES East Pacific Zonal Transect (GP16)
<p><strong>From the NSF Award Abstract</strong><br />
The mission of the International GEOTRACES Program (<a href="https://www.geotraces.org/" target="_blank">https://www.geotraces.org/</a>), of which the U.S. chemical oceanography research community is a founding member, is "to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean, and to establish the sensitivity of these distributions to changing environmental conditions" (GEOTRACES Science Plan, 2006). In the United States, ocean chemists are currently in the process of organizing a zonal transect in the eastern tropical South Pacific (ETSP) from Peru to Tahiti as the second cruise of the U.S.GEOTRACES Program. This Pacific section includes a large area characterized by high rates of primary production and particle export in the eastern boundary associated with the Peru Upwelling, a large oxygen minimum zone that is a major global sink for fixed nitrogen, and a large hydrothermal plume arising from the East Pacific Rise. This particular section was selected as a result of open planning workshops in 2007 and 2008, with a final recommendation made by the U.S.GEOTRACES Steering Committee in 2009. It is the first part of a two-stage plan that will include a meridional section of the Pacific from Tahiti to Alaska as a subsequent expedition.</p>
<p>This award provides funding for management of the U.S.GEOTRACES Pacific campaign to a team of scientists from the University of Southern California, Old Dominion University, and the Woods Hole Oceanographic Institution. The three co-leaders will provide mission leadership, essential support services, and management structure for acquiring the trace elements and isotopes samples listed as core parameters in the International GEOTRACES Science Plan, plus hydrographic and nutrient data needed by participating investigators. With this support from NSF, the management team will (1) plan and coordinate the 52-day Pacific research cruise described above; (2) obtain representative samples for a wide variety of trace metals of interest using conventional CTD/rosette and GEOTRACES Sampling Systems; (3) acquire conventional JGOFS/WOCE-quality hydrographic data (CTD, transmissometer, fluorometer, oxygen sensor, etc) along with discrete samples for salinity, dissolved oxygen (to 1 uM detection limits), plant pigments, redox tracers such as ammonium and nitrite, and dissolved nutrients at micro- and nanomolar levels; (4) ensure that proper QA/QC protocols are followed and reported, as well as fulfilling all GEOTRACES Intercalibration protocols; (5) prepare and deliver all hydrographic-type data to the GEOTRACES Data Center (and US data centers); and (6) coordinate cruise communications between all participating investigators, including preparation of a hydrographic report/publication.</p>
<p>Broader Impacts: The project is part of an international collaborative program that has forged strong partnerships in the intercalibration and implementation phases that are unprecedented in chemical oceanography. The science product of these collective missions will enhance our ability to understand how to interpret the chemical composition of the ocean, and interpret how climate change will affect ocean chemistry. Partnerships include contributions to the infrastructure of developing nations with overlapping interests in the study area, in this case Peru. There is a strong educational component to the program, with many Ph.D. students carrying out thesis research within the program.</p>

Collaborative Research: GEOTRACES Pacific Section - Nd isotopes and REEs in the South Pacific
https://osprey.bco-dmo.org/project/728066
Collaborative Research: GEOTRACES Pacific Section - Nd isotopes and REEs in the South Pacific
<p>NSF abstract:<br />
Neodymium isotopes (Nd) and rare earth elements (REE) are recognized by the GEOTRACES program as key trace elements and isotopes (TEIs) because they trace the sources and mixing of water masses. Therefore, transport data generated by Nd measurements will potentially advance our understanding on the dominant processes that drive TEI distribution in the ocean. There is a particular need for Nd measurements in the South Pacific because current observations do not agree with GCM models. Researchers from Columbia University and Oregon State University will analyze seawater, aerosols, water column particulates, and sea-floor sediments for Nd, strontrium, and REE during the upcoming 2013 GEOTRACES cruise. Because of the geographical transect of the GEOTRACES Pacific section cruise, investigators will assess impacts made by a suite of biological, chemical, and physical processes including: boundary exchange, high productivity, surface addition from aerosols, addition to bottom waters from detached nephloid layers, particles from hydrothermal vents, reversible scavenging, and groundwater fluxes. Furthermore, within the Peru-Chili Oxygen Minimum Zone (OMZ), investigators will utilize the TEI cerium to better understand relative effects of lateral and vertical processes. By improving understanding of the distribution of TEIs, results will also enhance biogeochemical models and advance knowledge of climate systems.</p>
<p>Broader Impacts: Research will advance careers of two young scientists, support education and training of Ph.D. and undergraduate students, and provide materials for outreach activities. Additionally, results will be published in scientific journals and all data will be submitted to the Biological and Chemical Oceanography Data Management Office.</p>

dataset
<p>Samples were filtered, acidified, and split at sea. Samples were collected by Niskin bottle and the towed GeoFish. Refer to the EPZT cruise report&nbsp;for more information on cruise operations (<a href="http://dmoserv3.whoi.edu/data_docs/GEOTRACES/EPZT/GT13_EPZT_ODFReport_All.pdf" target="_blank">http://dmoserv3.whoi.edu/data_docs/GEOTRACES/EPZT/GT13_EPZT_ODFReport_All.pdf</a>).&nbsp;</p>
<p>We prepared our 5L split for neodymium isotopic analysis following Shabani et al. (1992). Samples were pH-adjusted to pH ~3.5, then pumped through 300 µl of HDEHP in a C18 cartridge to capture REEs. Rare earth elements were eluted from the cartridge using 6M HCl, then Nd was isolated using sequential chromatographic columns: AG50-X8 (BioRad) and Ln-Spec (Eichrom). Neodymium isotopic measurements were made at Lamont-Doherty Earth Observatory (Palisades, NY) using a Thermo Neptune multicollector ICP-MS.</p>
<p>For REE concentrations we removed an aliquot after pH-adjustment of each sample. Sample methodology is described in Behrens et al. (2006), as Lab #3. We preconcentrated 20 ml of sample offline using a SeaFast PICO system (ESI), then analysed the resulting solution at Oregon State University (Corvallis, OR) using a Thermo X-Series II ICP-MS.</p>
<p>Problem Report: Cerium measurements yielded questionable data during a couple of run days, these data are indicated using IODE quality flag 3– Questionable Data. Sample gaps in REE concentrations are due to analytical error during pre-concentration, sample gaps in Nd isotope data are due to insufficient quantity of Nd to make a measurement.</p>
Specified by the Principal Investigator(s)
<p>Neodymium isotope ratios were corrected using JNdi-1 standard for reference (Tanaka et al., 2000). Dissolved concentrations were determined by external calibration. Calibration standards were diluted by weight and pre-concentrated using the same method as the samples. To account for evaporation we included pre-concentrations of an in-house REE consistency standard at regular intervals. Validation of the correction was done by additional pre-concentrations and measurements of two in-house seawater samples, one from Bransfeld Strait (~1100m depth) and one from nearshore California (~surface depth).</p>

PI Supplied Instrument Name: Instrument Name: GeoFish Towed near-Surface Sampler Instrument Short Name:GeoFish Instrument Description: The GeoFish towed sampler is a custom designed near surface (2 meters or less) sampling system for the collection of trace metal clean seawater. It consists of a PVC encapsulated lead weighted torpedo and separate PVC depressor vane supporting the intake utilizing all PFA Teflon tubing connected to a deck mounted, air-driven, PFA Teflon dual-diaphragm pump which provides trace-metal clean seawater at up to 3.7L/min. The GeoFish is towed at up to 13kts off to the side of the vessel outside of the ship's wake to avoid possible contamination from the ship's hull. It was developed by Geoffrey Smith and Ken Bruland (University of California, Santa Cruz). Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/31/
