A Self-Closing Plankton Net for Horizontal Towing

Nature volume 88, page 597 (29 February 1912) | Download Citation



A SELF-CLOSING plankton net has long been needed for horizontal towing. It is especially necessary for the investigation of the vertical distribution of pelagic organisms. Numerous attempts have therefore been made, from the time of Pavesi (1883) onward, to devise a satisfactory instrument for this purpose. The latest, and apparently the most satisfactory one of its kind, has been designed by Prof. Kofoid after suggestions from Dr. G. H. Fowler, of the Research expedition.
