Abstract

Carbon geochemistry is presented for subsurface fluids collected from Cork Observatories U1382A and U1383C installed on the Mid-Atlantic Ridge at North Pond as well as from bottom seawater. Data are summarized from fluids collected in 2012, 2014 and 2017. Parameters measured or calculated are pH, total alkalinity, DIC concentrations, d13C and D14C values and DOC concentrations, d13C and D14C values. Understanding carbon cycling in cool oceanic crust at sites like North Pond contributes to qua...

Results from fluids sampled in 2012 and 2014 are published in Table 1 of Shah Walter et al., 2018. Revised results for DOC isotopic values were subsequently released by NOSAMS radiocarbon facility and publisshed in an addendum: Shah Walter et al., 2022. Results from fluids sampled in 2017 were published in Table 1 of Trembath-Reichert et al., 2021 and Shah Walter et al., in prep.
