Figure 52. Knudsen bottom sampler designed by Martin Knudsen, a professor at the University of Copenhagen. This machine was meant to improve the sampling ability of the Petersen sampling device in more compact sediment layers. It was tested in the Oresund between Denmark and Sweden off the DANA in 11 meters of water in 1926.
