Limnology global inland waters as part of the Earth System created a sub-discipline called global limnology. This approach considers the role of inland aquatic ecosystems in carbon cycling. Limnology is closely related to aquatic ecology and hydrobiology, which study aquatic organisms and their interactions with the abiotic (non-living) environment. While limnology has substantial overlap with freshwater-focused disciplines (e.g., freshwater biology), it also includes the study of inland salt lakes. The term limnology was coined by François-Alphonse Forel (1841–1912) who established the field with his studies of Lake Geneva. Interest in the discipline rapidly expanded, and in 1922 August Thienemann (a German
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,
