Figure 12. Borgert net devised by Dr. Adolph Borgert of Hamburg in 1893. Having found the Hensen and Buchet nets too heavy, too complicated, and difficult to manage, and too expensive, Dr. Borgert designed this net for collecting plankton at the surface at high speed. This net was first tested from the steamer BARCELONA between Hamburg and the western Mediterranean.
