Online_Linkage: https://doi.org/10.5066/P13XVXQC Description: Abstract: Stable carbon isotope ratios (d13C), stable nitrogen isotope ratios (d15N), and molar percentage data of amino acids were determined on one to five cm subsamples of sediment push cores collected from the Escanaba Trough during May to June 2022. Purpose: Data were obtained to assess organic carbon storage, reactivity, and cycling within sediments of the Escanaba Trough, a hydrothermal spreading center which contains critical minerals. This work aids our understanding of the geochemistry of marine mineral host sediments and hydrothermal vent processes throughout the global ocean.

Online_Linkage: https://doi.org/10.1021/ac00178a015 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Instrument performance was monitored using both external and internal amino acid standards and directly measured d15N-amino acid and d13C-amino acid values were corrected based on bracketing external standards (McCarthy and others, 2004). The amino acid d13C values were determined from the measured values of the amino acid derivatives following the approach of Silfer and others (1991) with corrections based on an amino acid mixture standard for which isotopic values had been independently determined by offline elemental analyzer analysis. The directly measured amino acid d15N values were also corrected based on bracketing external standards as described in McCarthy and others, 2013. -8888 indicates peak was below the detection limit of 300 mV for carbon and 60 mV for nitrogen. The standard deviation of each isotope and molar percentage value was calculated from triplicate injections. Logical_Consistency_Report: Molar percentage data was checked to ensure the sum of the percentage of all individual amino acids was equivalent to one hundred percent. Completeness_Report: Dataset is considered complete for the information presented as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal accuracy for each sample was obtained from the ROV's Ultra Short Baseline Positioning System (USBL) navigation after calibration to the CASIUS (Calibration of Attitude Sensors In USBL Systems) calibration system. Accuracy for this depth is approximately 10 to 20 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The vertical accuracy was determined using multiple DVLs (Doppler Velocity Loggers) on the ROV, which are accurate to less than 1 m. Lineage: Process_Step: Process_Description: SEDIMENT COLLECTION. Samples were collected aboard the R/V Thomas Thompson via push coring using the ROV Jason. Once recovered shipboard, pore waters were extracted via rhizon samplers, cores were subsectioned into one to five cm slices, the exterior sediment which was in contact with the core liner was removed, and remaining sediment was stored frozen in pre-combusted glass jars. Process_Date: 20220611 Process_Step: Process_Description: COMPOUND SPECIFIC ISOTOPE ANALYSIS OF AMINO ACIDS: Amino acids were purified prior to compound specific isotope analysis of amino acids (CSI-AA) according to protocols of the McCarthy lab at the University of California, Santa Cruz (McCarthy and others, 2004). Sediments were subject to acid hydrolysis by adding 6N HCl to each sample, evacuating the headspace with N2 gas, and heating at 110 degrees Celsius for 20 hours. Samples were then mixed, centrifuged at 2200 revolutions per minute for five minutes (min), and supernatant pipetted off to new vial. This process (mixing, centrifuging, and removal of supernatant) was repeated with 1 mL 6N HCl and four 1 milliliter rinses of MilliQ H2O. The supernatant from all HCl and MilliQ H2O rinses were combined and dried under N2 gas at 80 degrees Celsius. Samples were redissolved in 0.1N HCl and a known quantity of Norleucine internal standard was added to each sample. Samples were filtered with pre-combusted glass wool followed by 1.0 micrometer glass fiber filters to remove large particles and then AA were purified using cation-exchange chromatography with Bio-Rad AG50WX8 resin (200-400 mesh) according to Takano and others (2010). Samples were dried under N2 gas at 80 degrees Celsius, redissolved in 0.2N HCl, flushed with N2 gas, and then heated at 110 degrees Celsius for 5 min to re-protonate the amino acids. Trifluoroacetyl isopropyl ester derivatives were prepared after Silfer and others (1991). A final purification step was completed via liquid-liquid extraction using chloroform and a phosphate buffer following Ueda and others (1989). Samples were dried under N2 gas at room temperature, rederivatized, and then stored at 20 degrees Celsius until analysis. Derivatized samples were analyzed for d13C-amino acid and d15N-amino acid isotope values by a Thermo Trace 1310 gas chromatograph coupled to an IsolinkII (Thermo combustion reactor 1000 degrees Celsius)/ConfloIV and Thermo Delta V Plus isotope ratio mass spectrometer. Samples were dried under N2 gas, redissolved in ethyl acetate, and injected in triplicate unless otherwise noted. Amino acids were separated for d15N analyses using a BPX5 column (60 meter x 0.32 millimeter, 1 micrometer film thickness; SGE Analytical Science, Trajan, Austin, TX, USA) and for d13C analyses using a DB-5 column (50 meter x 0.32 millimeter, 0.52 micrometer film thickness; Agilent Technologies, Santa Clara, CA, USA). The injector temperature was 250 degrees Celsius with He column flow rate of 2 mL/min. The GC temperature program for nitrogen isotope analysis was: initial temp = 70 degrees Celsius hold for 1 min; ramp 1=10 degrees Celsius/min to 185 degrees Celsius, hold for 2 min; ramp 2 = 2 degrees Celsius/min to 200 degrees Celsius, hold for 10 min; ramp 3 = 30 degrees Celsius/min to 300 degrees Celsius, hold for 6 min. The GC temperature program for carbon isotope analysis was: initial temp = 75 degrees Celsius hold for 2 min; ramp 1 = 4 degrees Celsius/min to 90 degrees Celsius, hold for 4 min; ramp 2 = 4 degrees Celsius/min to 185 degrees Celsius, hold for 5 min; ramp 3 = 10 degrees Celsius/min to 250 degrees Celsius, hold for 2 min; ramp 4 = 20 degrees Celsius/min to 300 degrees Celsius, hold for 5 min.
