<div><p>Methodology: </p>
<p>Sediment samples were collected from hydrothermal areas of Guaymas Basin in the Gulf of California during cruise AT3706 of R/V Atlantis in December 2016. Push cores were obtained using the human-occupied deep diving vehicle Alvin during dives 4867 to 4872. Porewater was extracted from the sediment by centrifugation and then filtered through a 0.2 μm syringe filter. For rate measurements, approximately 3 mL of live sediment was transferred into a modified Hungate tube as described previously (Bowles et al., 2011). At each depth, triplicate live samples and one killed control were collected for the quantification of acetate and methanol turnover rates. The details of the rate measurements can be found in Zhuang et al. (2018). </p>
<p>Instruments: </p>
<p>Methanol and ethanol in the porewater were quantified with a purge and trap system connected to a GC–FID (SRI) (Zhuang et al., 2018).</p>
<p>Issues of note: Due to the limited volume of porewaters, methanol and ethanol were not determined for most of the samples collected from Dives 4867 to Dive 4870.</p>
<p>Missing data identifiers:<br />
* B.D.: Below detection limit.<br />
* nd:Not determined. nd is the default missing data identifier in the BCO-DMO data system.</p></div>

<div><p>BCO-DMO Data Manager Processing Notes:<br />
* Data submitted in Excel file "Data submission OCE.xlsx" sheet "Rate" extracted to csv<br />
* added a conventional header with dataset name, PI name, version date<br />
* modified parameter names to conform with BCO-DMO naming conventions (spaces, +, and - changed to underscores). Units in parentheses removed and added to Parameter Description metadata section.<br />
* The default missing identifier in the original file N.D. for "not determined" is displayed as "nd" in the data. nd is the default missing data identifier in the BCO-DMO system.<br />
* removed metadata notes at the bottom of the file and moved to parameter descriptions. E.g. "B.D.: Below detection limit."<br />
* Date formats converted to ISO 8601 yyyy-mm-dd<br />
* Lat/lon converted to decimal degrees from degrees decimal minutes<br />
* values rounded to integer instead of the scientific notation for _time_to_ columns which have units of days. (Acetate_turnover_time_to_methane, Actate_turnover_to_CO2, <br />
Methanol_turnover_time_to_methane, Methanol_turnover_to_CO2)</p></div>
