“…Within N nutrients, nitrate demonstrated to be the dominant along the whole period, with global mean values of ~ 18 µM and reaching values up to ~ 50 µM (total discharge of N ~ 1.23 Ton DIN y−1). A very high load of organic matter (from ~ 2000 mg Cm−3 in the fall up to ~ 4000 mg Cm−3 during summer) is discharged from these streams into the marine coastal zone (which represents ~ 214 Ton POC y−1) and, even until now, response effects have not been recorded there. …”
