Open ocean regions receive significant amounts of land-based N from atmospheric deposition ( 25 Tg N yr Dentener pers. comm.). This estimate of atmospheric deposition does not include dissolved organic nitrogen (DON), which may account for from 20% to as much as 80% of the total dissolved N in rainwater in remote marine locations (Cornell et al., 1995, 2001, 2003 Mace et al. 2003). Keeping in mind that this estimate of DON is uncertain because of the...
