Sept. 19th - Oct. 10th 2000
This cruise was organised by Wolfgang Balzer from the Institute for
Marine Chemistry of the University Bremen. The ain objectives of the cruise
were to investigate the distribution of nutrients and trace elements
in the water column and their transport from the photic zone into the sediments
in the upwelling region off the Namibian coast and to determine the effects
of bioproductivity and hydrography on the composition of radioisotopes
in the water column and surface sediments in the Angola and Cape basins.
In addition, Claudia Sprengel (University Bremen) and Markus Geisen
(NHM) had the possibility to carry intensive sampling for coccolithophores
resulting in
Light microscopy on board and scanning electron microscopy work
at the NHM confirmed the hight diversity and abundance of coccolithophores
in the samples. Until now 450 isolations have been made from the net samples,
hopefully resulting in several of new cultures. For a text version of
the report produced click here .
