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,
Forensic limnology base line samples then it concludes the information viable. In 2006, scientists began creating a diatom database. It is the 'fingerprint system' for diatoms. The computer recognizes different diatom species based on shape and color characteristics. The tallying of colonies present in a sample, as well as the preferences of flora for diatom colonies are in the system so that scientists can access the information. But, as of 2012 the database is not complete and not used in courts. As of 2012, a small percentage of forensic limnology is used as evidence in courts. The presence of diatoms in air,
