Stable carbon isotopes of DOC from GO-SHIP cruises Dataset Description: Methods and Sampling: <p>Seawater samples&nbsp;were obtained from three GO-SHIP Repeat Hydrography transects to measure stable carbon isotopic composition of solid-phase extracted dissolved organic matter (SPE-DOC <em>δ</em><sup>13</sup><em>C</em>).&nbsp;Transect&nbsp;P16N (151°W) sampled in the year 2015, P18 (103-110°W)&nbsp;in 2016 and 2017, and transect&nbsp;I07N (50-70°E) in 2018&nbsp;aboard the NOAA Ship Ronald H. Brown (see Figure 1), at or within 1 station of an associated total DOC sample&nbsp;(Druffel et al., 2019, 2021, 2023). “Surface” and “deep” samples were collected at 0-200 meters&nbsp;and 2000-4000 meters, respectively. Due to the integration of seawater among different stations and depth, we report the weighted average depth which is the weighted mean that incorporates the relative amount of each water depth into the final value. (See Supplemental Files section for the equation).&nbsp;</p>
<p>&nbsp;Due to excess water availability, two samples (called "seawater duplicates or SD) were collected from P18 stations 77-79 (in deep water), and 168 (in surface water).&nbsp;For seawater samples from P18 and IO7N, solid phase extraction (SPE) was performed at sea using PPL cartridges (Bond Elut-PPL, 1&nbsp;gm 6&nbsp;ml, Part No. 12255002) according to Dittmar et&nbsp;al.&nbsp;(2008) and stored in the dark at 4°C until elution at UC Irvine. Seawater samples from the P16N cruise were processed after four years of freezing.&nbsp;Samples were then acidified to pH 2 with sulfuric acid (ACS grade, Lot #160,128) and extracted onto PPL cartridges. Before elution, PPL cartridges were dried under a steady stream of ultra-high purity N<sub>2&nbsp;</sub>gas&nbsp;for 30&nbsp;min to remove residual MilliQ water (3&nbsp;ppb DOC). SPE-DOC was eluted with LC/MS grade methanol following established methods (Dittmar et&nbsp;al.,&nbsp;2008). However, the elution volume of methanol was increased to 32&nbsp;mL to increase yield of SPE-DOC (Lewis et&nbsp;al.,&nbsp;2020). SPE-DOC was eluted into pre-weighed and pre-combusted (540°C/2h) 50&nbsp;mL centrifuge vials (VWR product #89091-460), and weighed after elution to determine the exact volume.&nbsp;</p>
<p>&nbsp;Splits were dried in a centrifugal evaporator with a −60°C chiller trap (Savant SpeedVac SC200) for a minimum of 12&nbsp;hours. Pre-baked cupric oxide and silver wire were added, and the outside of these quartz tubes were cleaned with acetone, dried, and placed inside larger 9&nbsp;mm diameter, 20&nbsp;cm long quartz vials. These “double tube” samples were sealed under vacuum and combusted at 850°C for two hours. Sample CO<sub>2</sub> was extracted cryogenically on a vacuum line and quantified manometrically.</p>
<p>Stable carbon isotopic measurements (<em>δ</em><sup>13</sup><em>C</em>) were made using a Gas Bench II and Thermo Electron Delta Plus mass spectrometer, and corrected using calibrated isotopic standards (NIST NBS-19). Measurements are reported as standard permille (‰) relative to V-PDB (Vienna Pee-Dee Belemnite) scale. Duplicate and triplicates taken from certain SPE-DOC extracts from all three cruises show our SPE-DOC δ<sup>13</sup>C measurement precision averages better than 0.2‰ providing confidence that the variability seen throughout different ocean regions is real.</p>

Cycling of Dissolved Organic Matter in the Pacific and Indian Oceans Using Radiocarbon

Cycling of Dissolved Organic Matter in the Pacific and Indian Oceans Using Radiocarbon
<p><em>NSF Award Abstract:</em><br />
Controls on the Aging of Marine Dissolved Organic Carbon</p>
<p>Most of the organic carbon in ocean water is in the dissolved form. Surprisingly, the age of this dissolved organic carbon is thousands of years old, even though it is thought to form during photosynthesis in the surface ocean. One explanation for the age of this carbon is the amount of time that it takes for carbon to circulate through the ocean. Investigators at the University of California Irvine (UCI) will investigate the aging of dissolved organic carbon in the Pacific, Southern and Indian oceans using C-14 isotopes. This work is important for knowing how carbon produced from human activities will be distributed on Earth in the future. This project will support the work of two graduate and two undergraduate students, providing hands-on experience that will prepare them for careers as scientists and educators. Both graduate students will be involved in a variety of educational activities. They will also help teach a short course on applications of C-14 in Ecology and Earth System Science for graduate students, technicians, postdocs and researchers during summer. UCI is a Hispanic-serving institution (27% of undergraduates identify as Hispanic), and 60% of students who attend UCI are first generation family representatives.</p>
<p>This study will examine the concentration, isotopic (14C, 13C) and molecular composition of dissolved organic carbon (DOC) in depth profiles from the Pacific, Southern and Indian Oceans. This information will help to determine the main controls on DOC cycling in the world’s oceans. The project will test the hypothesis that circulation is the primary control on DOC cycling in the deepest water (>3500 meters). The research will also investigate two alternative processes that could influence the age of DOC in deep water (2000-3000 meters): (1) dissolution of surface-derived particles and (2) input of ancient carbon from hydrothermal vents and flanks. Spectroscopic and spectrometric measurements designed to characterize a portion of the DOC will be performed on surface and deep water. Results will be incorporated into an inverse model of DOC cycling to determine the main processes controlling the DOC cycle in the ocean. DOC may serve as a sink for excess carbon dioxide produced from human activities and the size of the refractory DOC pool in the ocean could increase as circulation slows. Measuring the 14C age of DOC in the surface and deep ocean is important for understanding how the global carbon cycle will change as the Earth's climate shifts.</p>
<p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p>

Gas Bench II
PI Supplied Instrument Name: Gas Bench II PI Supplied Instrument Description:Stable carbon isotopic measurements (δ13C) were made using a Gas Bench II and Thermo Electron Delta Plus mass spectrometer Instrument Name: Thermo-Fisher Scientific Gas Bench II Instrument Short Name:GasBench II Instrument Description: An on-line gas preparation and introduction system for isotope ratio mass spectrometry that is designed for high precision isotope and molecular ratio determination of headspace samples, including water equilibration, carbonates and atmospheric gases. The instrument allows for the use of a dual viscous flow inlet system of repetitive measurements of sample and standard gas on a continuous flow isotope ratio mass spectrometer (CF-IRMS) system. The sample volume is the sample vial (instead of a metal bellows), and the reference gas volume is a pressurized gas tank. The instrument consists of a user programmable autosampler, a gas sampling system, a maintenance-free water removal system, a loop injection system, an isothermal gas chromatograph (GC), an active open split interface, a reference gas injection system with three reference ports, and one or two optional LN2 traps for cryofocusing. The gas sampling system includes a two port needle which adds a gentle flow of He into the sample vial, diluting and displacing sample gas. Water is removed from the sample gas through diffusion traps. The loop injector aliquots the sample gas onto the GC column, which separates the molecular species. The reference gas injection system allows accurate referencing of each sample aliquot to isotopic standards. The system can be used with several options including a carbonate reaction kit that allows injection of anhydrous phospohric acid into sample vials.
Note "Finnigan GasBench-II" is the previous brand name of this instrument.
