LIMNOLOGY Limnology is the oceanography of lakes (Forel 1892)… Forel, F.A. 1892-1901 Le Léman: monographie limnologique Editions Rouges & Cie, Lausanne. the study of inland waters (1922) International Association of Theoretical and Applied Limnology 1922
Limnology is: … "the study of inland waters, lakes, reservoirs, rivers, streams, and wetlands as systems. … a multidisciplinary field that involves all sciences that can be brought to bear on understanding the nature of such waters: the physical, chemical, earth, and biological sciences, and mathematics". Edmondson, 1994

The multiple claws resemble the multiple images used by Duchamp to indicate movement in his 1912 “Nude Descending a Staircase” –240 years ahead of its time.)
