Other nitrogen concentrations were ammonium, ranging from <0.1-95 µmol/L, nitrite and nitrate concentrations were <0.1-0.66 µmol/L and <0.1-8.51 µmol/L respectively and organic nitrogen concentrations varied from 0-9.44 µmol/L. Various reactions between the oxidation states were studied by calculations of redox potentials for given redox pairs.
Styrkur annara N tegunda voru ammoníum, <0.1-95 µmol/L, nítrít og nítrat voru <0.1-0.66 µmol/L og <0.1-8.51 µmol/L hvort um sig og styrkur lífræns köfnunarefnis var 0-9.44 µmol/L. Ýmis hvörf á milli oxunarstiga voru skoðuð með útreikningum á afoxunarmætti gefinna oxunarpara.
