On this cruise CTD 1 was used only!
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, nitrite, and nitrate determination bv MiniMon via the sea
water pipe and daily reference samples.
Determination of the pH value (CTD samples and continuously).
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 for the
determination of chlorophyll according to Jeffrey and Humphrey after the cruise.
The determination of alkalinity of sea water was not feasible due to a malfunction of the
instrument. Only the first two stations could be sampled.
Radiochemistry:
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.
270 | samples taken at selected stations at great depths for the determination of
strontium and tritium after the cruise and of cesium on board.
One 600 | surface water samples for test purposes after the cruise.
