Description:
A phytoplankton net is described with which samples from six different depth zones can be obtained by a single vertical haul. The closing net is released by an electromagnet through single conductor wire (220 V D.C.). On a revolving disc which is driven by a spring, there are six buckets which are successively brought before the net opening. The parts made of bolting silk can be exchanged, the entrance opening can be reduced. The apparatus is independent from depth by means of pressure compensation.
