Surface active substances in the water column during POLARSTERN cruise ANT-XXI/3 (EIFEX) ...
Surface active substances (SAS) in the water column were measured by voltammetry using the electrochemical probe o-nitrophenol (ONP) during EIFEX, a mesoscale open ocean iron enrichment experiment in the Southern Ocean. SAS levels were low throughout the experiment (<0.005 - 0.03 mg/L Triton X-10...
