Limnology zoologist) and Einar Naumann (a Swedish botanist) co-founded the International Society of Limnology (SIL, from Societas Internationalis Limnologiae). Forel's original definition of limnology, "the oceanography of lakes", was expanded to encompass the study of all inland waters, and influenced Benedykt Dybowski's work on Lake Baikal. Prominent early American limnologists included G. Evelyn Hutchinson, Ed Deevey, E. A. Birge, and C. Juday. Physical properties of aquatic ecosystems are determined by a combination of heat, currents, waves and other seasonal distributions of environmental conditions. The morphometry of a body of water depends on the type of feature (such as a lake, river,
Association for the Sciences of Limnology and Oceanography Association for the Sciences of Limnology and Oceanography Initiated in 1947, the Association for the Sciences of Limnology and Oceanography (ASLO), formerly known as the American Society of Limnology and Oceanography, is a scientific society with the goal of Advancing the Sciences of Limnology and Oceanography. With approximately 4000 members in nearly 60 different countries, ASLO is the largest scientific society, worldwide, devoted to either limnology or oceanography or both. ASLO’s mission is to foster a diverse, international scientific community that creates, integrates and communicates knowledge across the full spectrum of aquatic sciences, advances public awareness and education about aquatic
