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 food, drink, and close contact is not variable enough to be supportive evidence in determining locations of events. Even so, an investigation requires the use of forensic limnology in order to estimate time of death, location of drowning, and the determining of suspect. If the results of forensic limnology are not used in prosecution, the results are used to understand the crime. Forensic limnology Forensic limnology is a sub-field of forensic botany, which examines the presence of diatoms in crime scene samples and victims. Different methods are used to collect this data but all identify the ratios of different diatom
