<div><p>Dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) were measured by high temperature (680 ºC) combustion using a Shimadzu TOC-L analyzer at the SOEST Laboratory for Analytical Biogeochemistry, University of Hawaii. Samples analyzed include those filtered in situ for crustal fluids as well as the CTD samples filtered on deck. Samples were acidified to pH <2 within the autosampler syringe and were purged with nitrogen to remove inorganic carbon. Five to six replicate analyses were performed using an injected sample volume of 150 μL. The detection limits of DOC and TDN were about 2 and 1.5 uM, respectively. Two consensus reference materials CRM, from University of Miami, deep seawater and low carbon water, were used extensively before, between, and after sample analysis to monitor analytical accuracy. The analytical reproducibility for DOC and TDN is better than 1.1 uM and 460 0.2 uM, respectively, by repeated analysis of four deep seawater CRM.</p></div>
Dissolved organic carbon and total dissolved nitrogen from the formation fluids recovered from the CORKs installed at the North Pond in 2012.
<div><p>Dissolved organic carbon and total dissolved nitrogen from the formation fluids recovered from the CORKs installed at the North Pond in 2012 on MSM20-5. The North Pond is an isolated, northeast-trending, ~8 km × 15 km sediment pond located on the western flank of the Mid-Atlantic Ridge (MAR) at 22°45' N and 46°05' W.</p>
<p>Details of these CORKS and their positions, construction and depth can be found in the Proceedings of the IODP expedition 336.

<p>In addition to NSF OCE-1061934 (to Girguis), this dataset was funded by C-DEBI (OCE-0939564) sub-award number 41940192 granted to Beate Kraft.</p></div>
