ion exchanger (KNIFC-PAN). 
100 I surface water samples for the on-board analysis of transuranic elements. 
Atmospheric Chemistry 
Continuous trace gas measurements of nitric oxides (NO,x, NO und NO»), of sulphur 
dioxide (SO»), ozone (Os), and of carbon dioxide (CO») by means of Airpointer (Co. 
‚ecordum/MLU, S/N: 2016-590). 
Remote sensing of NO» and SO»by MAX-DOAS measurements (Multi-axis Differential 
Optical Absorption Spectroscopy, Institute of Environmental Physics, University of 
Bremen, system of station Wedel). 
Monitoring of current AIS signals in order to relate measured increased concentrations to 
surrounding ships. 
Organic Pollutants 
Determination of polar and non-polar organic and inorganic pollutants as, e.g. pesticides, 
chlorinated hydrocarbons (CHC), polycyclic aromatic hydrocarbons (PAH) and trace 
metals in sediment cores and sediment pore water (Project NOAH-Synthesis). 
Trace Metals: 
Determination of metal concentrations in sea water and suspended matter. Sampling via 
Clean CTD with GoFlo sampler or MERCOS sampler with plastic covered wire.
