||Estimated according to Annual hydrothermal flow (water mass) associated with ridges and ride-flanks of 2.4E16 kg H2O. If
one assumes that complete denitrification occurs in this entire
flow and that the original nitrate concentration is 30µM,
a denitrification rate of ~10 Tg N/year results (There are 14 g of N in one mole of Nitrate): (2.4E16 kg water/year)*(0.00003 moles nitrate/kg water)*(14g N per mole)=10.08E12g N/year=~10Tg N/year
