Christian Andreas Viktor Hensen and his studies of plankton

This paper gives a brief account of the attempt by the German zoologist Christian Andreas Viktor Hensen to quantify the amount of floating organisms in the sea, which he defined for the first time as plankton. To do this, he invented new collecting and analysing methods, and in 1887 led the first major German oceanographic expedition. Despite arousing criticisms, his methods influenced others to begin quantitative sampling and led to his recognition as one of the founders of ecology.
