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
Limnology yellow-brown, tea-coloured waters. These categories do not have rigid specifications; the classification system can be seen as more of a spectrum encompassing the various levels of aquatic productivity. There are many professional organizations related to limnology and other aspects of the aquatic science. Some of these include: Professional and academic limnologists also participate in professional societies with a broader focus. There are numerous peer-reviewed scientific journals that include limnology articles. Some of these include: Limnology Limnology ( ; from Greek λίμνη, "limne", "lake" and λόγος, "logos", "knowledge"), is the study of inland aquatic ecosystems. The study of limnology includes aspects
