RR2004 Dissolved Trace Metals Dataset Description: Methods and Sampling: <p>To characterize the nutritional values of Southeast Pacific Ocean waters and determine the limiting nutrient(s) in each regime, uncontaminated seawater samples (n=173) were drawn from<strong> </strong>21 deployments<strong> </strong>of nine 5-liter (L) Niskin-X bottles<strong> </strong>suspended from Kevlar line at varying depths between 30 meters (m) and 1050 m.</p>
<p><strong>Sampling procedure:</strong><br />
Niskin-X bottles were carried from a UNOLS trace-metal clean van to the starboard squirt boom, where they were secured by hand to the 1/4-inch Aracom Miniline using stainless steel hardware. The Niskins were attached incrementally so that each Niskin was lowered to its target depth when the deepest Niskin reached its target depth (~1000 m). Niskin bottles were allowed to sit at depth for ~5 minutes before triggered to close using a series of Teflon messengers.</p>
<p>The Niskins were recovered and returned to the trace metal clean van, where they were secured in PVC racks with wedges<strong> </strong>to keep the caps tight. A series of air lines were connected to the air ports at the top of the Niskins, which were then<strong> </strong>overpressured (~6-8 psi) with filtered air using a Gast pump.</p>
<p>Unfiltered samples were drawn from each Niskin-X for salinity and major nutrient measurements (ODF). The remainder of the volume was filtered using 47-millimeter (mm), 0.4-micrometer (μm) pore-size Isopore membrane filters<strong> </strong>installed in Advantec filter cartridges. The filtrate was collected into trace metal-cleaned (acid-washed) 125-milliliter (mL) LDPE bottles for dissolved trace metal concentrations.</p>
<p><strong>Special modifications to sampling operations:</strong></p>
<p>1. A small<strong> </strong>Ronstan Series 60 Single Orbit block (model #7298755) was used instead of a larger metering block, which eliminated the risk of the line jumping the sheave and the need for a deck-mounted snatch block. The block was attached to the starboard squirt boom which allowed for the Niskin-X bottles to be attached to the Aracom line without having to lean too far over the side of the ship.</p>
<p>2. The Niskin-X bottles were deployed from the starboard side of the ship by securing the Hawboldt winch at an angle, just aft of the ResTech locker. This allowed the Aracom line to be threaded through the Ronstan block mounted to the squirt boom. Even in heavier seas, the Niskin-X bottles were deployed reliably and reproducibly due to this arrangement (which was designed by Matt Durham, UCSD ResTech).</p>
<p>3. In order to better estimate the depths at which the bottles were deployed, a miniature temperature and pressure sensor (centi-TD, 5-1500 m; Star Oddi) was secured to each Niskin-X bottle. These sensors recorded the temperature and pressure (i.e., depth) at preset intervals (every 60 seconds). These depths were double-checked by comparing the salinity and nutrient values determined in samples from each Niskin-X bottle against (1) the temperature and salinity values from the ship's CTD sensors and (2) discrete salinity and nutrient concentrations determined from the ship's bottles.</p>
<p><strong>Analytical procedure (dissolved trace metals):</strong><br />
Filtered seawater samples were acidified to 0.024 M HCl using concentrated Fisher Optima HCl. The samples were allowed to sit for ~6 months to allow complete desorption of metals from the bottle walls, according to Jensen et al. 2020.</p>
<p>Aliquots of acidified seawater (~15 mL) were transferred to 30 mL FEP bottles (Savillex) for UV-oxidation (1.5 hours), according to Milne et al. 2010. The samples were then processed online using a SeaFAST S2 system (Elemental Scientific, Inc.), which includes online buffering with ammonium acetate buffer before passing over a 200-microliter (µL) column filled with Nobias Chelate PA-1. The extraction procedure captures trace metals from 10 mL of buffered seawater while allowing most of the major sea-salt cations (e.g., Na and Mg) to be directed to waste. The column is then eluted with 0.5 mL of 1.6 M HNO<sub>3</sub> (Fisher Optima) to release the trace metals, and this eluate is introduced directly to the High Resolution-Inductively Coupled Plasma-Mass Spectrometer (Thermo ELEMENT 2) for analysis. By eliminating the major seasalts and concentrating the trace metals by a factor of ~20 (10 mL sample loaded, 0.5 mL eluted), the matrix effects are minimized, and the metal detection limits are increased.</p>
<p>Metal concentrations were quantified upon comparison against external standards prepared in low metal surface seawater, which were processed identically to the samples. Blanks (n=93) were determined by running a complete loading-extraction-elution cycle without seawater (i.e., leaving the sample probe out of any sample or rinse solution, taking up only HEPA-filtered air). These blanks were applied to all samples and reference materials to determine any background metal contributions from the SeaFAST system, ICPMS sample introduction components, or reagent blanks.</p>
<p>Reference materials were included in every analytical run, including the GEOTRACES GS (n=9) and GD (n=3) consensus reference materials, as well as an in-house "daily check" sample of surface seawater collected from the Gulf of Mexico (n=18).</p>
<p>Details of the reference materials and daily check sample are included with the air blanks in the "QA/QC" summary file "BCO-DMO_SAMW_2021_dTM_QAQC_2024_06_04" (PDF and Excel formats provided; see Supplemental Files section of metadata).</p>

Collaborative Research: Biogeochemical and Physical Conditioning of Sub-Antarctic Mode Water in the Southern Ocean

Collaborative Research: Biogeochemical and Physical Conditioning of Sub-Antarctic Mode Water in the Southern Ocean
<p><em>NSF Award Abstract:</em><br />
Cold surface water in the southern Indian Ocean sinks to about 500 meters and travels in the dark for thousands of miles before it resurfaces some 40 years later near the equator in the other ocean basins. This major water mass is named the Sub-Antarctic Mode Water (SAMW). Nutrients it contains when it warms and rises into the sunlit subtropical and tropical waters are estimated to fuel up to 75% of the microscopic plant growth there. Before it sinks, the chemical properties of the SAMW are modified by the growth and distinct physiology of two common phytoplankton; diatoms with shells made of silica, and coccolithophores with carbonate shells. Local physical dynamics influence where and how fast these two phytoplankton classes grow. Consequently, differing nutrient and trace chemical fingerprints are established at the point of SAMW formation. This project is an exceptionally detailed field and modeling effort that will document and quantify the remarkable, interconnected processes that chemically connect two important oceanic ecosystems half a world apart. The scientists leading the project will study the complexity of the biological and chemical conditioning of the SAMW and thus provide critical data about the large-scale oceanic controls of the biological carbon pump that removes atmospheric carbon dioxide to the deep ocean over millennial timescales. Scientific impact from this project will stem from significant peer-reviewed publications and improved predictive models. Societal benefits will develop from training of a range of scholars, including high school, undergraduate, and graduate students, as well as technical and post-doctoral participants. A high school teacher and science communication specialist will go to sea with the project and share experiences from the ship with students on shore via social media and scheduled web interactions.</p>
<p>To examine how SAMW formation and subduction controls the productivity of global waters well to the north, two January expeditions to the SE Indian Ocean will identify, track, and study the unique mesoscale eddies that serve as discrete water parcels supporting rich populations of either coccolithophores or diatoms plus their associated microbial communities. The eddies will be tracked with Lagrangian Argo drifters and observations will be made of exactly how SAMW is chemically conditioned (i.e. Si, N, P, Fe, and carbonate chemistry) over time scales of months. Using data obtained on the feedback between ecological processes and nutrient, trace metal, and carbonate chemistry in these eddies and on related transect cruises, the project will have three main goals: (1) determine the rates at which SAMW coccolithophores and diatoms condition the carbonate chemistry plus nutrient and trace metal concentrations, as well as assess taxonomic and physiological diversity in the study area with traditional methods plus next-generation sequence DNA/RNA profiling, (2) explore growth limitations by iron, silicate and/or nitrate in controlling algal assemblages and genetic diversity, and (3) combine these findings with the Ekman- and eddy-driven subduction of SAMW to examine biogeochemical impact on a basin scale, using both observations and global numerical models. A meridional survey from 30 to 60 degrees south latitude will be used to characterize the larger-scale variability of carbonate chemistry, nutrient distributions, productivity, genetics and biomass of various plankton groups as SAMW is subducted and proceeds northward.</p>
