Multiple carbon incorporation strategies support microbial survival in cold subseafloor crustal fluids
19). Decreasing cell concentrations after drilling has also been observed in other CORKs [Juan de Fuca ridge flank; ( 21)] and groundwater well systems ( 5)], low cell counts likely indicate that the North Pond system had recovered from drilling and that the 2017 fluids (and resulting data) are the best representation of microbial activity in the cold, oxic crustal subseafloor aquifer to date. Table 1 North Pond CORK fluids and bottom water values for cell enumeration, dissolved inorganic carbon (DIC), and dissolved organic carbon (DOC) from 2017 samples collected for this study.
