Equipment and Methods 
Marine Physics: 
CTD Seabird SBE 911+ (SBE1, S/N 0577) with SBE 43 oxygen sensor, 3-Kanal 
Backscat II fluorimeter and rosette water sampler with twelve 10-liter bottles. 
ScanFish (SF1 = S/N 380, SF2 = S/N 390) with Seabird SBE 911+ CTD, AMT oxygen 
sensor, and TRIOS fluorimeter „TwinFlu“ (SF1, S/N 6811). 
Seabird thermosalinograph SBE 21 with turbidity and chlorophyll sensors. 
Nutrients: 
Oxygen determination according to Winkler-Carpenter by means of a SIS Dissolved 
Oxygen Analyser (DOA) with photometric end point determination at selected depths. 
Continuous pH determination via the sea water pipe. 
Continuous phosphate, silicate (MiniMon) and nitrate determination (nitrate spectrometer) 
via the sea water pipe and daily reference samples. 
Determination of the pH value (CTD samples). 
Determination of depth of visibility by means of a Secchi disk at every daylight station. 
Filtration of surface water samples and freezing of the glass fiber filters for the 
determination of chlorophyll via Lorenzen photometry after the cruise. 
Determination of alkalinity of sea water. 
Extra samples for the UK Shelf Sea Biochemistry Programme: 
- Daily filtration of nutrient samples (polycarbonate filters) and freezing. 
- Daily surface samples for DIC/TA (they were poisoned with Mercuric chloride). 
Radiochemistry: 
1 
2 x 35 | surface water for the extraction of strontium 90 after the cruise. 
One liter surface samples for the analysis of tritium after the cruise. 
100 I surface samples for the determination of plutonium und americium on board. 
270 | samples taken at selected stations at great depths for the determination of 
strontium and tritium after the cruise and of cesium, plutonium, and americium on board. 
At the above mentioned deep stations additionally 100 | surface water samples for the 
determination of plutonium and americium, which had been filtered before analysis in 
contrast to the other samples. 
100-150 I surface water samples for the on-board analysis of cesium-137 by means of a 
ion exchanger. 
Atmospheric Chemistry 
Continuous trace gas analysis of nitric oxides (NO,, NO und NO») by means of HORIBA 
APNA-370, of sulphur dioxide (SO) by means of HORIBA APSA-370 and of ozone (Os) 
by means of HOROBA APOA-370. 
CO» and water vapor determination by means of LiCOr840a (Co. LiCOR). 
Recording of meteorological parameter like wind speed and direction, air temperature, 
air pressure and precipitation by means of the meteorological monitoring system WS- 
600-UMB (Co. Lufft) and data logger ulOx (Co. Gemi).
