Determination of depth of visibility by means of a Secchi disk at daylight stations. 
Filtration of surface water samples and freezing of the glass fiber filters at -80°C for the 
determination of chlorophyll according to Aminot and Rey after the cruise. 
Visible pollution: 
Surface sampling of visible pollution (ViPo) using a 0.405 mm Neuston net and 
characterization of the non-biota part (e.g., paraffin wax, vegetable oil, plastics) in the lab 
after the survey. Individual net hauls for 30 min with 3 kn ship speed. 
Technical Problems 
CTD data acquisition: 
In the beginning of the survey it was not possible to establish a stable NMEA-input (data from 
navigation: position and time for start, bottom and end of the profile) to the CTD deck unit. 
Thus, for stations 1-11, 17 and 33 these data were added afterwards on the basis of the 
DSHIP data set. Only the bottle-files were corrected during the cruise.
