Abstract

This thesis compiles different studies that help to identify where, how and by whom N2O is produced in the ocean. A mixed layer budget of N2O in the upwelling region off Mauritania is calculated to quantify the N2O transport from the ocean interior to the atmosphere. N2O production mechanisms are investigated in a comparison study of N2O and δ15N-Nitrate measurements in the tropical Atlantic and Pacific Oceans. Evidence for N2O production from archaeal nitrification is presented from field studies as well as from culture experiments, and a method for improved measurements of hydroxylamine in seawater is presented that can help to identify the production mechanisms of N2O during nitrification.
