    Notes: Abstract From March to July 1989 (JGOFS pilot study), measurements were carried out on the oxygen uptake of natural zooplankton communities on five drifting stations (about three weeks each) in the Atlantic from 18°N to 72°N after a method of Martens (1986). The weight specific respiration rate decreased from south to north parallel to the water temperature, whereas the amount of mesozooplankton increased. No significant differences in the oxygen uptake of the zooplankton community between the five stations could be found. A rough estimate showed that less than 2% of the phytoplankton carbon was assimilated by the mesozooplankton per day. This is thought to reflect a typical spring situation. The weight specific respiration rate is influenced significantly by the water temperature and the mean length of the zooplankter.

    Inorganic phytoplankton nutrients in the Wadden Sea areas off Schleswig-Holstein. II. Dissolved ortho-phosphate and reactive silicate with comments on the zooplankton (1992)

    Notes: Abstract In the summer months of 1984, 1986, 1987 and 1988, several stations off the west coast of Schleswig-Holstein were investigated with regard to the situation of ortho-phosphate, reactive silicate and mesozooplankton. An increase in phosphate was observed, whereas an increase in silicate could only be found in the areas influenced by the River Eider. Polychaete larvae show a decreasing tendency in the summer months; this is thought to be influenced by water temperature.
