H2O2 in the marine troposphere and seawater of the Atlantic Ocean (48 N - 63 S)
Abstract.Concentrations of H2O2 in gas phase and seawater have been measured in pristine regions of the Atlantic Ocean during the RV Polarstern expedition ANT X-1 from 11/15/91 to 01/02/92. A broad maximum of gaseous H2O2 mixing ratio in the troposphere was found between the tropic of cancer and the...
