Figure 29. Gilson sounder, described in 1906 by Gustave Gilson of the University of Louvain. He described a perfected scoop sounder which was similar to the Stellwagen sounder but contained a number of improvements for assuring a larger quantity of sediment obtained than with the earlier instrument. It was first tested in 1899 near Ostende off the coast of Belgium.
